Zhang, Lei, Shoutian Shao, Suxin Chen, Xinyu Li, Rui Jiang e Ziqi Li. "Individualized and accurate eco-design knowledge push for designers: a CAD-based feedback knowledge push method for the eco-design". Concurrent Engineering 29, n. 2 (24 gennaio 2021): 153–68. http://dx.doi.org/10.1177/1063293x20985539.
Testo completoAbstract (sommario):
In the conceptual design phase of eco-products, the evaluation of products eco-design is often considered by designers after determining the design scheme. In order to improve the eco-design efficiency, a CAD-based feedback knowledge push method was proposed to meet the designer’s eco-design knowledge requirements. Combine with the designer knowledge background, classified eco-design knowledge, and decomposed design tasks, eco-design knowledge requirements of designers can be obtained. Based on the cosine similarity algorithm of the knowledge vector space model (VSM), the knowledge requirements of the designer and the knowledge in the knowledge database are matched, and the eco-knowledge is actively pushed to the designer. The feedback and evaluation of designers on the initial push of knowledge was recorded by the system. When the designer is assigned relevant eco-design tasks again, the system conducts secondary filtering of eco-design knowledge through previous feedback records and pushes the filtered knowledge to designers, so as to achieve accurate feedback knowledge push. A CAD-based eco-design knowledge push prototype system for automotive products is developed. The eco-design of the front-end module of the automotive is used as an example to verify the effectiveness of the above method.

Testo completoAbstract (sommario):
Reflecting upon the constructionist model "learning-bymaking," prototyping (prototype making) as a product design and research approach is well recognised for assured development of innovative concepts in individual or collaborative working environments. A prototype is typically used as a tool to support experiments or interventions and to evaluate research goals. It also facilitates participatory design and user-centred design. However, it carries both coded and tacit knowledge that we, design educators and practitioners, find problematic to explain and instruct, particularly to non-designers. This paper amalgamates and argues the characteristics of prototyping including types, formats, and principles through literature review. Reflecting upon the designer’s intentions and the dual coding cognitive learning process, the author proposes a descriptive model that illustrates the dual actions experienced by the designer which can enable study on the improvement of the prototyping process.

A project-oriented type of thought is very important for the profession of a designer. The article describes project-oriented thought as the chief element of its activity. Students studying design constantly polish their skills in practice when creating tutorial design projects and thereby develop project-oriented thought. Academic disciplines of the artistic cycle are directed at the development of project-oriented thought, and they include such an academic discipline as calligraphy. Knowledge, proficiency and skills developed by calligraphy are revealed by means of research. The article produces a complex structure of project-oriented thought based on Siegfried Begenau’s work and an analogy from the perspective of mastering calligraphy. On the basis of this analogy lies the principle of creation of a calligraphic work, from the idea to its realization. Study of calligraphic rules of writing develops manual dexterity, creativity and imagination and provides discipline, which is an important trait of the designer’s profession. Perfection of calligraphic elements and fonts in practice becomes conducive to elaboration of project-oriented thought. The conclusion is also arrived at that projectoriented thought is developed among designers faster after they undergo studies of a basic course of calligraphy.

ABSTRAKMicrostock menjadi salah satu unsur penting yang menunjang aktifitas desainer grafis sehari-hari. Baik untuk mendapatkan konten grafis digital, mengetahui perkembangan tren desain kekinian dan menjadi jawaban mereka untuk bekerja secara freelance. Penelitian ini menyajikan apa dan sejauh mana hubungan microstock dengan desainer grafis, kesadaran desainer grafis tentang hak kekayaan intelektual dan fenomena pengaruh microstock terhadap kesadaran hak kekayaan intelektual desainer grafis. Jenis pendekatan yang digunakan adalah fenomenologi Edmund Husserl karena objek yang diteliti berkaitan dengan kesadaran manusia. Fokusnya adalah memaparkan fenomena kesadaran sebagai dasar tindakan yang diperoleh dari pemaknaan pengalaman desainer grafis selama berhubungan dengan microstock. Berdasarkan hasil penelitian, dapat disimpulkan bahwa microstock terbukti memiliki pengaruh terhadap kesadaran desainer grafis tentang hak kekayaan intelektual. Pengalaman-pengalaman tindakan yang berkaitan dengan microstock baik sebagai kontributor maupun non-kontributor telah membentuk suatu pengetahuan baru hingga akhirnya melahirkan kesadaran tentang hak kekayaan intelektual terutama pada masalah lisensi dan royalti. Kesadaran tersebut lalu menjadikan desainer grafis mampu aktif merespon fenomena penghargaan maupun pelanggaran hak kekayaan intelektual di lingkungannya masing-masing.ABSTRACTThe Microstock Influence on Consciousness of Graphic Designer’s Intellectual Property Right’s. Microstock has been one of important elements to support the daily activities of graphic designers. These activities involve finding digital graphic contents, finding out the current development of design trend and becoming their answer to work freelance. This research presents what and to what extent is the relationship between microstock and graphic designers, graphic designer’s consciousness of intellectual property rights and the phenomenon of microstock’s effect on graphic designers’ consciousness of intellectual property rights. The approach used is Edmund Husserl’s phenomenology since the object studied is related to human’s consciousness. The focus is to elaborate the phenomenon of consciousness as the basis of action which is obtained from interpreting graphic designer’s experience when they interact with microstock. Based on the research result, it can be concluded that microstock is found to have some influence on graphic designer’s consciousness of intellectual property rights. The experiences of action related to microstock both as contributors and non-contributors have shaped a new knowledge that in turn gives birth to their consciousness of intellectual property rights, particularly on license and royalty issues. This consciousness then allows graphic designers to actively respond to the phenomena of appreciation and violation of intellectual property rights in their own environment.

Testo completoAbstract (sommario):
The AIA design thinking has been validated in complex design tasks, which includes three overlapping design thinking fields and uses the knowledge field theory as a theoretical mechanism of knowledge flow among design thinking fields. Meanwhile, the design of complex sociotechnical systems highly relies on multidisciplinary knowledge and design methods. Despite the emergence of knowledge management techniques (ontology, expert system, text mining, etc.), designers continue to store knowledge in unstructured ways. To facilitate the integration of knowledge graph and design thinking, we introduce an integrated approach to structure design knowledge graph with the AIA design thinking, which organizes existing design knowledge through Agent (concept)-Interaction (relation)-Adaptation (concept) framework. The approach uses an optimized convolutional neural network to accomplish two tasks: building concept graph from text and stimulating design thinking information processing for complex sociotechnical system tasks. Based on our knowledge graph, the validation experiment demonstrates the advantages of promoting the designer’s extension of idea space and idea quality.

Testo completoAbstract (sommario):
Biology provides a rich and novel source of inspiration for product design. An increasing number of industrial designers are gaining inspiration from nature, producing creative products by extracting, classifying, and reconstructing biological features. However, the current process of gaining biological inspiration is still limited by the prior knowledge and experience of designers, so it is necessary to investigate the designer’s perception of biological features. Herein, we investigate designer perceptions of bionic object features based on Kansei engineering, achieving a highly comprehensive structured expression of biological features forming five dimensions—Overall Feeling, Ability and Trait, Color and Texture, Apparent Tactile Sensation, and Structural Features—using factor analysis. Further, producing creative design solutions with a biologically inspired design (BID) has a risk of failing to meet user preferences and market needs. A user preference prediction support tool may address this bottleneck. We examine user preference by questionnaire and explore its association with the perceptual evaluation of designers, obtaining a user preference prediction model by conducting multiple linear regression analysis. This provides a statistical model for identifying the relative weighting of the perception dimensions of each designer in the user preference for an animal, giving the degree of contribution to the user preference. The experiment results show that the dimension “Overall Feeling” of the designer perception is positively correlated with the “like” level of the user preference and negatively correlated with the “dislike” level of the user preference, indicating that this prediction model bridges the gap caused by the asymmetry between designers and users by matching the designer perception and user preference. To a certain extent, this research solves the problems associated with the cognitive limitations of designers and the differences between designers and users, facilitating the use of biological features in product design and thereby enhancing the market importance of BID schemes.

Testo completoAbstract (sommario):
Until now, industrial designers are solely educated with the epistemology of dialectical materialism; meanwhile, the spiritual aspect is often segregated from education affairs. Many kinds of literature highlighted that this segregation could lead to negative impacts. Supposedly as a Muslim, learning about our Creator through Asma’ul Husna is an essential trait to develop designers’ value, also known as sahsiah or characteristic of excellence. Therefore, this paper attempted to study the adaptation of Asma’ul Husna in the existing design practice among Muslim designers and at the same time devote the existent designer’s knowledge and awareness to this understanding. A set of questionnaires were distributed using stratified sampling. The result showed that the majority of the respondents did not adapt Asma’ul Husna in the existing design practice due to limited knowledge on ways to integrate Asma’ul Husna in the design process. Designers who claimed to use Asma’ul Husna in design are either still confused with the usage or only limits the usage to motif and zikr. As an overview, this paper highlights the general view of an adaptation of Asma’ul Husna’s among designers and emphasises the urgency to develop a guideline for designers to implement the values in their design process.

Testo completoAbstract (sommario):
During the design and development of new products, design engineers use many techniques to generate and define new and “good” concepts. Inherent in this search for solutions is the conscious and unconscious reliance on prior experience and knowledge, or design-by-analogy. In this paper, a quantitative metric for design-by-analogy is developed. This metric is based on the functional similarity of products. By using this product-similarity metric, designers are able to formalize and quantify design-by-analogy techniques during concept and layout design. The methods, as developed in this paper, allow a designer with limited experience to develop sophisticated solutions that enhance the overall design of a new product. Also, a designer’s current design-by-analogy vocabulary can be extended beyond his or her immediate experience, providing access and contributions to new domains by discovering different products with common functions. The similarity metric and its application are clarified and validated through a case study. The case study is the original design of a pickup winder.

Agent-oriented computing is a technique for generating an agent that operates autonomously according to behavioral knowledge. Moreover, an agent can have a characteristic called “learning” skill. More efficient operation of an agent can be expected by support an agent designer who designs and develops an agent equipped with “learning” skill. The authors propose a design support mechanism of a learning agent on a repository-based agent framework called the DASH framework. The proposed mechanism enables an agent designer to design and implement the learning agent without great expertise, thereby reducing the designer’s burden. Herein, they explain the DASH framework, Q-Learning, and the proposed design support mechanism. Moreover, the authors demonstrate the effectiveness of the proposed method using some experiments.

Testo completoAbstract (sommario):
In the conceptual design stage, inspirational sources play an important role in designers’ creative thinking. This paper proposes a retrieval method for semantic-based inspirational sources, which helps designers obtain inspirational images in the conceptual design stage of emotional design. The core principle involves solving the designer’s own deficiencies in associations and limited knowledge, by bridging the “semantic gap” faced by designers when they use Kansei words for inspirational sources. This method can be divided into two aspects: (1) based on the semantic richness of Kansei words, the first part describes how a lexical ontology for Kansei words called KanseiNet is constructed and proposes a spreading activation mechanism based on KanseiNet to complete the semantic expansion of Kansei words; (2) the second part describes how, using existing semantic techniques, relevant design website resources are crawled and analyzed, images’ context descriptions and Kansei evaluations are extracted, and Kansei evaluation index of inspirational images is established. The KanseiNet for Chinese is first constructed, and the Sources of Inspiration Retrieval System for Emotional Design (SIRSED) is developed. An experiment comparing the existing image retrieval systems with SIRSED proved the latter to be a more comprehensive and accurate way for designers to access inspirational sources.

Testo completoAbstract (sommario):
Purpose – The purpose of this paper is to introduce a library website model. Further, the paper discusses a designer’s checklist and an evaluative instrument that were constructed based on the proposed model. Design/methodology/approach – The model was developed through a Delphi study that was participated by two panels of experts. The researcher communicated with the panel members via e-mail using two Delphi instruments designed out of two item pools that were developed based on the knowledge gained from surveying the literature, visiting the selected libraries and exploring the library websites. Then, a designer’s checklist and an evaluative instrument were derived from the proposed model through a series of brainstorming sessions. Findings – The proposed model consisted of altogether 140 items (60 web content elements and 80 web design features). The designer’s checklist comprises all 140 items, and the evaluative instrument comprises 60 content elements and 57 design features. Research limitations/implications – This study has developed an academic library website model and derived two instruments based on the proposed model. Further studies are needed to customize, particularly, the web content pillar of this conceptual model, to meet the specific needs of different types of libraries including public libraries, special libraries, school libraries, etc. Practical implications – The designer’s checklist and the evaluative instrument derived from the proposed model are useful tools for library professionals in designing, re-designing, maintaining and evaluating their library websites. The librarians may use these tools for both institutional and research purposes. Originality/value – The model and the two instruments proposed by this study are unique in focus, origin, content and presentation.

Testo completoAbstract (sommario):
This article reviews organizing information—after gathering it in the first place—is the key to actually using it. In this web-linked, data-rich world, engineers, like other professionals, must organize for easy access both the growing amount of information they create during the course of their day and the information they need to do their jobs. Indexing and linking documents and other information sources is an important first step, but engineers also must have a way to organize the information so they can find it via an easy search. Concept maps can be used to collect a designer’s knowledge and cognitive skills not available to other designers. The concept map explains through a formal step-by-step visual representation how an engineer attacked a design problem, struggled with it, attacked it from another angle, and eventually solved it. The maps are archived in a database and can be referred to for help with similar problems.

Testo completoAbstract (sommario):
This article presents a number of novel approaches for deriving intelligence from the parameterisation of computer-aided design models to assist the engineer in making manufacturing-related decisions. During the design process, a disjoint can occur between the nominally defined computer-aided design feature parameters and the dimensions which govern manufacture and influence ease of product assembly. In this work, a link between the two representations is established, which simplifies the process of using the parameters defining the features in the computer-aided design model to make manufacturing-related decisions such as the allocation of dimensional tolerances or dealing with fit issues. It also offers insights about how the model should be parameterised to provide the optimal model utility from the designer’s perspective with respect to the manufacturing domain.

Testo completoAbstract (sommario):
The use of constraint-based knowledge assists designers in making well-informed decisions at different stages of digital design process. A constraint is conceived as a direct control on design formation, or as a filter which does not impose a control over a formation process. The paper aims to gain insights into the ways the designers manipulate constraints in the digital design process. It investigated whether the same type of buildings, designed by the same or different architects, presents different approaches to deal with the same constraint. Scenarios of handling a constraint using shaping and validation processes were identified before initial modelling, through modelling, and after modelling. Constraints can effectively participate in design formation by proposing a new shape or a typical shape at pre-modelling. They are refining or developing the initial design through modelling, and optimizing or enhancing the design after modelling. Furthermore, constraints play significant roles in the feasibility study of design solutions. This is done by evaluating the initial forms and selecting the fittest through modelling, in addition to testing and filtering the solution space after modelling, and approving the final design. The paper examined the impact of wind on the morphology of twelve contemporary tower designs. The findings support the opinion that constraints may not restrict the designer’s free will, inspiration, and creativity. They revealed that different scenarios of wind-driven processes had implemented at different design stages even by the same designer. The wind constraint had a substantial impact on the derivation of new morphologies. Through modelling, it had an active role in the refinement of the initial architectural and structural design. Constraint-based design was handled in iterative processes of evaluating and developing or refining the initial forms through modelling; and optimizing or enhancing, testing, and approving the final forms after modelling.

This article provides a soft skills detailed analysis. This group of skills, and the paper will prove that, represents one of the modern designer’s professional skills main components. The «soft skills» concept essence and structural components are revealed. The following categories of soft skills were studied: key emotional qualities of a person, skills of managing their own emotions, skills of interaction with the outside world and in society, as well as skills formed by individual characteristics of human thinking. The non-technical skills importance in the designer study is determined, their formation process is also studied. Next, the content of «soft skills», required for the formation of undergraduate students, who master the direction of training 54.03.01 «Design», is determined. In this article, in addition, the competencies provided for by the Federal State Educational Standard for Higher Education, which are directly related to the process of forming such skills in students of the «Design» direction are examined. Within the framework of this article, the analysis of the modern, dynamically developing system of the higher education is carried out. On its basis, the necessity of introducing such structural and organizational elements into the training process of future bachelors, which will most likely contribute to the soft skills formation is proved. The role of the higher school teacher in the process of the designer’s soft skills forming is also defined. The soft skills of the future design bachelor are considered by the author not only as a set of knowledge, skills and abilities, but also the sum of personal qualities based on tolerant, humanistic, ethical principles. According to the author, the human personality of the future designer finds the most complete expression at the level of professional and social culture. The article proves the necessity of applying a system-value approach in the process of preparing bachelor’s degrees in design. In turn, one of the most significant components of this approach is soft skills.

Model-based development is a potential approach to designing complicated mechatronic systems. This paper proposes a product design framework for mechatronic systems, which integrates model-based development with prototyping and focuses on its process of deployment with hypothesis and verification. SysML is adopted as the modeling language for representing the mechatronic system without depending on specific domains, and FMEA is adopted as the method for describing the results of validation by prototyping. The DRIFT framework is used to capture designer’s operations on the design tools of SysML and FMEA and to manage its process. This study defines design concepts and design operations that are extracted from the patterns embedded in design process with SysML and FMEA. A design example of a ball-sorting robot is created using LEGO Mindstorms to demonstrate the proposed framework.

In this paper main tasks of industrial design (especially transportation design) were discussed and the importance of development not only of conventional designs for production, that are economically efficient, but also conceptual designs was shown. That concepts form the vision of the future, that we all are striving for, they can form trends and show new options and alternatives, that new technologies can open for us. For that, in this paper the new classifier of conceptual designs is shown, and the distinctive competences of concept-designer are high lightened. Classifier shows the difference between industrial design, concept design and concept-art. Concept design mostly located in the area around the border of scientific knowledge and that allows in the new designs to consider the high-end scientific researches and at the same time propose some new ideas and possibly the new vector for scientific research in different fields. Concept designer’s competencies for this activity include the ability to work with the future (futurology) and additional competencies in directing and script writing for decent visual storytelling and future world’s value transfer.

Testo completoAbstract (sommario):
The efficient and accurate management of time in simulations of hybrid models is an outstanding engineering problem. General a priori knowledge about the dynamic behavior of the hybrid system (i.e. essentially continuous, essentially discrete, or ‘truly hybrid’) facilitates this task. Indeed, for essentially discrete and essentially continuous systems, existing software packages can be conveniently used to perform quite sophisticated and satisfactory simulations. The situation is different for ‘truly hybrid’ systems, for which direct application of existing software packages results in a lengthy design process, cumbersome software assemblies, inaccurate results, or some combination of these independent of the designer’s a priori knowledge about the system’s structure and behavior. The main goal of this paper is to provide a methodology whereby simulation designers can use a priori knowledge about the hybrid model’s structure to build a straightforward, efficient, and accurate simulator with existing software packages. The proposed methodology is based on a formal decomposition and re-articulation of the hybrid system; this is the main theoretical result of the paper. To set the result in the right perspective, we briefly review the essentially continuous and essentially discrete approaches, which are illustrated with typical examples. Then we present our new, split system approach, first in a general formal context, then in three more specific guises that reflect the viewpoints of three main communities of hybrid system researchers and practitioners. For each of these variants we indicate an implementation path. Our approach is illustrated with an archetypal problem of power grid control.

In the context of fashion/textile innovations towards Industry 4.0, a variety of digital technologies, such as 3D garment CAD, have been proposed to automate, optimize design and manufacturing processes in the organizations of involved enterprises and supply chains as well as services such as marketing and sales. However, the current digital solutions rarely deal with key elements used in the fashion industry, including professional knowledge, as well as fashion and functional requirements of the customer and their relations with product technical parameters. Especially, product design plays an essential role in the whole fashion supply chain and should be paid more attention to in the process of digitalization and intelligentization of fashion companies. In this context, we originally developed an interactive fashion and garment design system by systematically integrating a number of data-driven services of garment design recommendation, 3D virtual garment fitting visualization, design knowledge base, and design parameters adjustment. This system enables close interactions between the designer, consumer, and manufacturer around the virtual product corresponding to each design solution. In this way, the complexity of the product design process can drastically be reduced by directly integrating the consumer’s perception and professional designer’s knowledge into the garment computer-aided design (CAD) environment. Furthermore, for a specific consumer profile, the related computations (design solution recommendation and design parameters adjustment) are performed by using a number of intelligent algorithms (BIRCH, adaptive Random Forest algorithms, and association mining) and matching with a formalized design knowledge base. The proposed interactive design system has been implemented and then exposed through the REST API, for designing garments meeting the consumer’s personalized fashion requirements by repeatedly running the cycle of design recommendation—virtual garment fitting—online evaluation of designer and consumer—design parameters adjustment—design knowledge base creation, and updating. The effectiveness of the proposed system has been validated through a business case of personalized men’s shirt design.

Often, dynamical aircraft systems cannot always be accurate because some approximation assumptions, imprecisions or uncertainties may have been introduced or imposed during the modeling process. Mathematical models of aircraft systems always contain uncertain elements, which model the designer’s lack of knowledge about some parameter values, disturbances and unmodeled dynamics. Using both Lyapunov’s direct method and the linear matrix inequality approach, we develop the controller design procedure, and give a definite feel for stability analysis and robust control for aircraft systems with significant uncertainty. An example of an uncertain thrust vectoring aircraft is studied to illustrate our control design strategy.

Abstract With the development of electro-hydraulic integration technology, the control accuracy, complexity and dynamic response characteristics of aircraft hydraulic system actions have become a hot topic in the field of hydraulics. The traditional hydraulic system design method mainly uses the designer’s knowledge and experience to construct a dynamic system with real components, and then tests on the system, this method is more difficult to adjust parameters. Therefore, taking the hydraulic system of an aircraft as an example, the simulation model of each component of the system is established by using modeling and simulation technology and graphical modeling method, so as to provide support for aircraft fault diagnosis and prediction.

This paper presents the design and implementation of a behavior-based control scheme. The construction of the set of behaviors is based on the use of fuzzy logic as a means for materializing the designer’s knowledge into the behaviors. The behavior set was established by left and right wall following and obstacle avoidance. These three behaviors were programmed and coordinated by a subsumption architecture or behavioral inhibition. Behavior simulations and coordination scheme design were tested by means of real experiments using a mobile robotic platform. Finally, the results are presented, where the control actions are executed by the robotic system achieving a secure navigation.

For various underground concrete structures (basements, tunnels), which remain permanently in the groundwater, watertight concrete is of increasing importance. Watertight concrete structures have several advantages over structures with exterior waterproofing membrane. The design and execution of watertight concrete structures is regulated by guidelines. Although these principles and procedures are widely used, it can be problematic to make them failure-free. The causes of this situation are manifold, but primarily related to the lack of designer’s knowledge and contractor’s technological indiscipline. Considering the importance of leaking separation cracks in terms of serviceability and durability of watertight structures, the contribution analyses constructional, technological and execution measures to reduce the occurrence of failures. Perhaps the paper can contribute to a better understanding of the behaviour and reasons of failures of this advanced technology.

Design education has undergone transformations over time, although less emphasis has been placed on developing core areas such as form and aesthetics. Learning processes in design education are creative and comprehensive, but to an extent, learning has become a mission with a large focus on relevance and societal benefits. The designer’s role has become somewhat more instrumental, and designers’ function more often as facilitators than creators. Nevertheless, form and aesthetics are important competences that enable students to work creatively with both processes and results. As creators, design students need to develop their personal comprehension of forms and aesthetic expressions. This article demonstrates how aesthetics are activated through assignments and exercises that leverage awareness and experiences of concrete forms and abstractions. The assignments and exercises were given to bachelor’s degree and master’s degree students in Product Design at Oslo Metropolitan University, Norway, and to students from all levels (bachelor’s, master’s and PhD) at UNESP, Bauru in Brazil. Aesthetic awareness relates to perception and abstract form principles demonstrated through assignments and exercises, including various dramaturgies, results, and reflections. Examples demonstrate how haptic experiences change the way students perceive forms and spaces, particularly when the visual senses are muted or removed. Based on the students’ reflections and the results of the exercises, knowledge achieved through their explorations is equally valuable beyond the actual properties of forms and the engagement of personal affect from the creative processes.Keywords: aesthetic awareness, abstraction, comprehension of form, creativity, design education

Abstract The search for representative resistant systems for a concrete structure requires deep knowledge about its mechanical behavior. Strut-and-tie models are classic analysis procedures to the design of reinforced concrete regions where there are stress concentrations, the so-called discontinuous regions of the structure. However, this model is strongly dependent of designer’s experience regarding the compatibility between the internal flow of loads, the material’s behavior, the geometry and boundary conditions. In this context, the present work has the objective of presenting the application of the strut-and-tie method in linear and non-linear on some typical structural elements, using the Evolutionary Topological Optimization Method (ESO). This optimization method considers the progressive reduction of stiffness with the removal of elements with low values of stresses. The equivalent truss system resulting from the analysis may provide greater safety and reliability.

Today, in the fashion sector, which can be regarded as the driving force behind Turkish exports, the need for designs and designers is increasing day by day in parallel with the developments in domestic and foreign markets. The process of production in the fashion sector can be divided into four groups, namely design, planning, production and marketing. The fundamental properties of the product are determined in the design department, which constitutes the basis of the production process. In this study, the purpose was to investigate how effects having or not having technical knowledge related to the garment production process on fashion designers’ designs. This study, in which qualitative research methods were used, was conducted using the case study design. For the sample group, criterion sampling, one of the purposeful sampling methods, was used and four designer were selected as the sample group. Research data were collected through interview, observation and document review. The data that were collected were evaluated through description and comparative analysis and then made into a report. After evaluation of research findings it has been reached that designers with technical knowledge on garment production process scored higher points on their illustrations. In terms of sub dimensions, in evaluations related to creativity dimensions, designers with technical knowledge, even with a slight difference, scored higher. When design is studied in terms of commercial value which is the other sub dimension, again, points of designers with technical knowledge fount higher.Keywords: Fashion Designer, Illustration, Creativity, Technical Knowledge

This paper describes a generic approach to guiding designers when making decisions during the early stages of design. The objective of the research is to enable designers to foresee unintended life-cycle consequences during mechanical component design. Engineering design is a process of evolving solutions to a design problem through the commitment of decisions. As a designer commits a new design decision, a more concrete design solution is generated. Decisions made can have intended and unintended consequences on the performance of the life phase activities that follow, such as manufacturing, assembly, and disposal. Many existing tools only consider the impact of the design solution on later life-cycle phases when the solution is almost complete. This makes changes expensive and difficult. This paper presents a novel approach to how consequences encountered in down stream life-cycle phases can be brought to the designer's attention early in generation of component form. For this purpose, a knowledge model has been derived from a phenomena model. The phenomena model describes how life-cycle consequences are generated during component synthesis. An insight into the representation of the resultant knowledge model is discussed through examples. The implementation of a prototype Knowledge Intensive CAD tool, entitled FORESEE, aimed at supporting life-oriented, feature-based component synthesis and exploration, is also described. The results of the evaluation of FORESEE with a range of designers show that by using the system designers are motivated to explore alternative design solutions and are able to make more informed design decisions. This highlights that the knowledge structure provides a base for extending feature-based component design to a ‘Design Synthesis for Multi-X’ approach.

Abstract This article explores dramatic spaces and their role in the intellectual construction of urban design in contemporary architecture. Dramatic space, and its role in intellectual construction, have become more relevant to the organization of urban design through constituting of high-rise buildings in the city’s photos, memory, and sense formation of events dramas in memories for the city. Contemporary architecture depends on a common principle by all designers in the desire to produce spaces involved by the receiver and help structure human relations by checking drama in their spaces to be building something different. Thus, The research problem was determined in revealing the comprehensive theoretical perception of the dramatic space formulas in contemporary architecture in general and the patterns of its realization in particular, that achieve a social and stable reaction. The research aimed to reach reveal the role of the mechanisms of creating drama in achieving new dimensions in the thought of contemporary architecture by creating patterns that bear the attribute of drama as space and according to the mechanisms and strategies of the dramatic system. Thus, Through the realization of drama in space, the topics are fragmented and multiple in thought, and the vision opens to the recipient to weave the plot according to the designer’s intellectual visions and his awareness of the event within the social system and transform it into a dramatic system through which knowledge is generated for the rest of the recipients in the interpretation or embodiment to reach the aesthetic and intellectual patterns inferred in urban spaces.

The focus of this paper is the design and player reception of a serious game called Missing released on Google Play with the intention of spreading awareness of trafficking and its impact on individuals and society. The aim of the paper is to investigate how the game has been received by its players, focusing on its trafficking theme, by analyzing player metrics and app store data available from the Google Play digital distribution system. The paper presents results focusing on three main knowledge contributions: the identification and characterization of the tension between the designer’s intention with a game’s mechanics and how they help to convey the message of the game, the identification of the complexity of finding relevant reviews relating to the serious theme of the game and the identification and characterization of the tension between the star rating and the content of the reviews. One of the conclusions is that even a negative review can mirror a positive result in terms of fulfillment of the purpose.

The design discipline is faced with radical changes related to new technologies and to an increasingly globalized world with more and more competitive markets. These factors are profoundly influencing methods and processes of design, and the knowledge and skills related to the designer’s role. Consequently, the design educational models are radically changing. Today, one of the most impacting evolutions is related to rapid prototyping techniques, which are bringing design practice closer to the auto-production. This emerging trend cannot be anymore supported with traditional didactic approaches, but it is necessary to create spaces for allowing students to learn, design and experiment in a shared way. This paper presents the Polifactory Lab at Politecnico di Milano, an innovative makerspace established with the aim of creating a new research and teaching space. In this paper, the authors present the Polifactory Lab, its theoretical purposes, and some examples of didactic activities carried out in the lab.

Reactor core design is inherently a multi-objective problem which spans a large design space, and potentially larger objective space. This process relies on high-fidelity models to probe the design space, and sophisticated computer codes to calculate the important physics occurring in the reactor. In the past, the design space has been reduced by individuals with extensive knowledge of reactor core design; however, this approach is not always available. In this paper, we utilize a set of high-fidelity models to generate a reduced-order model, and couple this with a genetic algorithm to quickly and effectively optimize a preliminary design for a prototypical sodium fast reactor. We also examine augmenting the genetic algorithm with physical programming to generate the fitness function(s) that evaluates the degree to which a core has been optimized. Physical programming is used in two variations of multi-objective optimization and is compared with a traditional weighting scheme to examine the solutions present on the Pareto front. Optimization on the reduced-order model produces a set of solutions on the Pareto front for a designer to examine. The uncertainty for the objective functions examined in the reduced-order model is less than 7% for the given designs, and improves as additional data points are employed. Utilizing a reduced-order model can significantly reduce the computation time and storage to perform preliminary optimization. Physical programming was shown to reduce the objective space when compared with a traditional weighting scheme. It also provides an intuitive and computationally efficient way to produce a Pareto front that meets the designer’s objectives.

Testo completoAbstract (sommario):
Abstract This paper critically assesses John Danaher’s ‘ethical behaviourism’, a theory on how the moral status of robots should be determined. The basic idea of this theory is that a robot’s moral status is determined decisively on the basis of its observable behaviour. If it behaves sufficiently similar to some entity that has moral status, such as a human or an animal, then we should ascribe the same moral status to the robot as we do to this human or animal. The paper argues against ethical behaviourism by making four main points. First, it is argued that the strongest version of ethical behaviourism understands the theory as relying on inferences to the best explanation when inferring moral status. Second, as a consequence, ethical behaviourism cannot stick with merely looking at the robot’s behaviour, while remaining neutral with regard to the difficult question of which property grounds moral status. Third, not only behavioural evidence ought to play a role in inferring a robot’s moral status, but knowledge of the design process of the robot and of its designer’s intention ought to be taken into account as well. Fourth, knowledge of a robot’s ontology and how that relates to human biology often is epistemically relevant for inferring moral status as well. The paper closes with some concluding observations.

Testo completoAbstract (sommario):
With the increasing demand for electronic products, the electronic package gradually developed toward miniaturization and high density. The most significant advantage of the Wafer-Level Package (WLP) is that it can effectively reduce the volume and footprint area of the package. An important issue in the design of WLP is how to quickly and accurately predict the reliability life under the accelerated thermal cycling test (ATCT). If the simulation approach is not adopted, it usually takes several ACTCs to design a WLP, and each ACTC will take several months to get the reliability life results, which increases development time considerably. However, simulation results may differ depending on the designer’s domain knowledge, ability, and experience. This shortcoming can be overcome with artificial intelligence (AI). In this study, finite element analysis (FEA) is combined with machine learning algorithms, e.g., Kernel Ridge Regression (KRR), to create an AI model for predicting the reliability life of electronic packaging. Kernel Ridge Regression (KRR) combined with the K-means cluster algorithm provides a highly accurate and efficient way to obtain AI models for large-scale data sets.

Testo completoAbstract (sommario):
The purpose of this article is to provide information about the approach to developing circular fashion collections concepts built from scratch. I documented my approach to design my collection otherways[project], launched in 2020, to understand and analyse the challenges and barriers stemming from applying circular design strategies. Current literature highlights organizational but also individual factors as instrumental in hindering the transition from a linear industry into a new one that embraces the circular economy as a solution to tackle environmental and societal issues. Bridging the various design stages and production, fashion designers play a major role for the urgent industry shift. However, limited time availability and a lack of knowledge and guidance often influence the adoption of new skills that can foster circular fashion design. To address this, I exemplarily applied circular design strategies and used reflective practice as a research method to analyse the technical as well as the cognitive impact of designing for a closed-loop business model. By using a visual diagram of a core loop with four additional satellites to map my design decisions against, I identified opportunities of designing with a circular strategy affecting all aspects from material sourcing to collection production and distribution, repair, reuse/closing the loop. The consideration of external factors such as customers (here users) enriches the value of circular design; hence, I conducted a free pilot with five users to test the effectiveness of my prototype collection. Open-ended questionnaires revealed their experience of wearing a garment of their choice and enabled a user-centric iteration process resulting in improving my collection for lease. Flexibility and systems thinking were main internal factors that I defined as essential for creating my circular collection concept alongside expanding the designer’s role from garment developer to facilitator of closed fashion loops.

Testo completoAbstract (sommario):
The surrogate-assisted optimization (SAO) process can utilize the knowledge contained in the surrogate model to accelerate the aerodynamic optimization process. The use of this knowledge can be regarded as the primary form of intelligent optimization design. However, there are still some difficulties in improving intelligent design levels, such as the insufficient utilization of optimization process data and optimization parameters’ adjustment that depends on the designer’s intervention and experience. To solve the above problems, a novel aerodynamic data-driven surrogate-assisted teaching-learning-based optimization (TLBO) framework is proposed for constrained aerodynamic shape optimization (ASO). The main contribution of the study is that ASO is promoted using historically aerodynamic process data generated during the gradient free optimization process. Meanwhile, nonparametric adjustment of the TLBO algorithm can help relieve manual design experience for actual engineering applications. Based on the structure of the TLBO algorithm, a model optimal prediction method is proposed as the new surrogate-assisted support strategy to accelerate the ASO process. The proposed method is applied to airfoil and wing shape designs to verify the optimization effect and efficiency. A benchmark aerodynamic design optimization is employed for the drag minimization of the RAE2822 airfoil. The optimized results indicate that the proposed method has advantages of high efficiency, strong optimization ability, and nonparametric characteristics for ASO. Moreover, the results of the wing shape optimization verify the advantages of the proposed methods over the surrogate-based optimization and direct optimization frameworks.

Though rule-based reasoning system is easy to create and convenient to extend, it is not flexible because of the demand for precise matching. Geometric reasoning system can obtain engineering semantic from CAD model and connect geometric topology with design knowledge, but it can not drive product design directly. Utilizing the complementary of rule-based reasoning and geometric reasoning, a product design method based on integrated geometric and rule-based reasoning is presented. The method can standardize the expression of design scheme which is from geometric reasoning, and dock seamlessly design scheme and input condition in rule-based reasoning system. Furthermore, the result of rule-based reasoning can drive product design directly. The operation of human-computer interaction and designer’s experience needed are decreased greatly. Digital target in locater is significant to harmonize aircraft tie-in. there are different types in it, and the amount of it is huge, so its design process is complicated and fussy. On the basis of the method, a rapid design software package for locator digital target design is developed and has been applied in aircraft assembly tooling design. The application has proved the method can improve design efficiency, standardization and intelligence.

Testo completoAbstract (sommario):
This paper investigates the use of typological knowledge in the visual modality through a computer framework that combines multidisciplinary technologies from computer science, that is, artificial intelligence, software engineering, database system, and programming language, to help provide solutions and services to building designers. The solving of design problems frequently involves visual thinking, which has to do with the intensive use of visual knowledge like pictures, images, and other types of visual displays. The recognized power of typological knowledge in design problem solving is applied to support the exploration of a diversity of possible design solutions represented in a pictorial mode. The innovative use of computer science technologies enables a smooth link of visual typological knowledge with the design goals. Within the framework, a core technology was designed to respond to a designer's specific needs through dynamic user viewpoint generation, so that design solutions are associated with relevant (retrieved) visual typologies from the knowledge base. This has been achieved in a two-way process, in which the designer establishes an interactive dialogue with an experimental computerized framework.

Testo completoAbstract (sommario):
Currently design documentation rarely records the designer's decision process or the reasons behind those decisions. This paper describes an effort to improve design documentation by having the computer act as an intelligent apprentice to the designer to capture the rationale during the design process. The apprentice learns about the features that make a specific case different from the standard. Whenever the designer proposes a design action that differs from the apprentice's expectations, the interface will ask for the designer for justifications to explain the differences. Later queries for design rationale are answered using a combination of the apprentice's domain knowledge and the designer-supplied justifications. The apprentice model is being implemented in a prototype system called ADD (Augmenting Design Documentation). The initial focus of the work is on HVAC (Heating, Ventilation, and Air Conditioning) design. Our starting point for implementing the apprentice model is observing how people develop HVAC system designs and then explain those designs.

A large number of publicly available documents, including patent documents and journal articles, can provide designers with creative stimuli, which could facilitate product innovation and collaborative design. As an important tacit knowledge, the acquisition, sharing, and reuse of design rationale (DR) is of great value to designers, which could help designers to better understand design intentions and ideas, support design automation, and promote better collaborative design. However, due to the fragmentation of DR in documentation, this hinders designer acquisition and reuse. If the DR fragments could be automatically extracted from the technical documents to build an interconnected knowledge network system, the problem would be effectively solved, which would further promote the development and utilization of digital archives. To address this issue, this study proposes a three-dimensional design knowledge network metamodel, Design Knowledge Semantic Network (DKSN), and a DKSN-based knowledge fusion method for the construction of a Design Knowledge Network (DKN). We set up an empirical experiment to verify the feasibility and performance of the method. Patent documents and open access research articles are used as sample documents, and a product data dictionary imported from ISO/TS 23768-1 is used as the predefined artifact dictionary. The results further confirm the feasibility and good application prospects of the proposed method.

Contemporary cities are witnessing momentous shifts in how institutions and individuals produce and circulate data. Despite recent trends claiming that anyone can create and use data, cities remain marked by persistently uneven access and usage of digital technologies. This is the case as well within the emergent phenomenon of the ‘smart city,’ where open data are a key strategy for achieving ‘smartness,’ and increasingly constitute a fundamental dimension of urban life, governance, economic activity, and epistemology. The digital ethnography has extended traditional ethnographic research practices into such digital realms, yet its applicability within open data and smart cities is unclear. The method has tended to overlook the important roles of particular digital artifacts such as the database in structuring and producing knowledge. In this paper, we develop the database ethnography as a rich methodological resource for open data research. This approach centers the database as a key site for the production and materialization of social meaning. The database ethnography draws attention to the ways digital choices and practices—around database design, schema, data models, and so on—leave traces through time. From these traces, we may infer lessons about how phenomena come to be encoded as data and acted upon in urban contexts. Open databases are, in other words, key ways in which knowledges about the smart city are framed, delimited, and represented. More specifically, we argue that open databases limit data types, categorize and classify data to align with technical specifications, reflect the database designer’s episteme, and (re)produce conceptions of the world. We substantiate these claims through a database ethnography of the open data portal for the city of Calgary, in Western Canada.

Testo completoAbstract (sommario):
As the complexity of building tasks and requirements increases, designers often find themselves confronted with interdisciplinary problems that go beyond the specific challenges and methods of architecture. The iterative nature of the design process results in a continuous exchange between creative, analytical and evaluative activities, through which the designer explores and identifies promising design variants. The ability to compare and evaluate relevant reference examples of already built or designed buildings helps designers to assess their own design and informs the design process.
