Dissertations / Theses on the topic 'Origami applications'

Origami, the art of folding paper, was once only an art form. In recent years, it has collided with the world of engineering and is acting as a source of inspiration for solutions to various engineering problems. Paper, the typical material used in the art form, is thin and works well for origami, but is not often suitable for use in engineering. Researchers have developed a handful of methods for accommodating thick/rigid materials in origami design. Most of these preserve only the kinematics of the model or its range of motion. Not only does the offset panel technique (OPT) preserve both the kinematics and the range of motion, it also allows for flexibility in design. This work focuses on the further development of the OPT and its potential to be implemented in real-world applications. The OPT provides design flexibility by allowing for the use of various and multiple materials, the modification of panel geometry, and the utilization of any rigid-foldable origami pattern. These and other capabilities are demonstrated in several application examples.

Origami can be a powerful source of design inspiration in the creation of reconfigurable systems with unparalleled performance. This thesis provides fundamental tools for designers to employ as origami-based designs are pursued in their respective fields of expertise. The first chapter introduces origami and makes connections between origami and engineering design through a survey of engineered applications and characterizing the relationship between origami and compliant mechanisms. The second chapter evaluates the creasing of non-paper sheet materials, such as plastics and metals, to facilitate origami-based compliant mechanism design. Although it is anticipated that most origami-based design will result from surrogate folds (indirect methods of replacing the crease), it is valuable to provide information that may help in more direct approaches for origami-based design in materials other than paper. Planar sheets of homogeneous material are considered as they maintain the principles fundamental to origami (flat initial state, low cost, readily available). The reduced stiffness along the axis of the crease is an enabling characteristic of origami. Hence a metric based on the deformation of the crease compared to the deformation of the panels enables engineering materials to be evaluated based on their ability to achieve the "hinge-like" behavior observed in folded paper. Advantages of both high and low values of this metric are given. Testing results (hinge indexes, residual angles, localized hinge behavior and cyclic creasing to failure) are presented for various metals and polymers. This methodology and subsequent findings are provided to enable origami-based design of compliant mechanisms. The third chapter proposes a basic terminology for origami-based design and presents areas of considerations for cases where the final engineering design is directly related to a crease pattern. This framework for navigating from paper art to engineered products begins once the crease pattern has been selected for a given application. The four areas of consideration are discussed: 1) rigid foldability 2) crease characterization 3) material properties and dimensions and 4) manufacturing. Two examples are concurrently presented to illustrate these considerations: a backpack shell and a shroud for an adjustable C-Arm x-ray device used in hospitals. The final chapter provides concluding remarks on origami-based design.

For origami-based designs to be functional, they need to be stable. Typically, stability is achieved through the introduction of exterior supports or members. This work focuses on incorporating stability into deployable origami-based engineering applications, including the development of deployable stiffeners or hard stops and generating concepts for stable origami-based systems in specific applications. Two types of deployable stiffeners are developed. Models for transcrease hard stops are presented, which can be directly implemented into origami-patterns to block motion at a specified angle. Thickness Utilizing Deployable Hard Stops (ThUDS), adapted from the transcrease hard stop models, can be implemented into thick materials for use in origami-based design. The application of self-deploying, self-locking ThUDS in an origami-based CubeSat reflectarray is shown, designed using optimization principles. Last, various multistable furniture concepts are presented, with stability incorporated into the concept design. These concepts focus on using composite wood as the base material, due to wood's abundance and commonality in furniture design.

La thèse conduit une analyse cinématique des mécanismes spatiaux allant de mécanismes sphériques aux mécanismes spatiaux sur-contraints basés sur la méthode matricielle D-H et l’applique pour explorer le comportement rigide de pliabilité et de mouvement des modèles d’origami. Dans ce processus, la pliabilité rigide du motif origami en torsion triangulaire est d’abord examinée sur la base de la cinématique du réseau de mécanismes 4 R sphériques et de nouveaux mécanismes 6 R sur-contraints dérivés par la technique du kirigami. Ensuite, la cinématique du mécanisme de Bricard 6 R plan-symétrique est analysée et ses variations de bifurcation sont discutées. Après cela, les résultats sont appliqués pour étudier le pliage symétrique de l’origami de la waterbomb à six plis à panneau épais, qui est modélisé sous laforme d’un réseau de mécanismes de Bricard 6 R plan-symétriques. Le comportement de mouvement de sa tessellation correspondante de feuille de zéro-épaisseur est démontré par unréseau de mécanismes 6 R sphériques. Enfin, le comportement de mouvement de la forme cylindrique fermée de l’origami de la waterbomb est analysé à travers une étude paramétrique, en le modélisant comme un réseau fermé de mécanismes 6 R sphériques. Ces études aident à approfondir la compréhension de la cinématique des mécanismes spatiaux et du mouvement rigide de l’origami, et à jeter les bases des applications techniques des mécanismes spatiaux et des motifs d’origami rigides<br>This dissertation conducts kinematic analysis of spatial linkages ranging from spherical linkages to overconstrained linkages based on the D-H matrix method, and applies it to explore the rigid foldability and motion behaviour of origami patterns. In this process, the rigid foldability of triangle twist origami pattern is firstly examined based on the kinematics of spherical 4 R linkage network and new overconstrained 6 R linkages are derived by kirigami technique. Then the kinematics of the plane-symmetric Bricard 6 R linkage is analyzed and its bifurcation variations are discussed. After that, the results are applied to study the symmetric folding of six-crease thick-panel waterbomb origami, which is modelled as a network of planesymmetric Bricard 6 R linkages. The motion behaviour of its corresponding tessellation of zerothickness sheet is demonstrated by a network of spherical 6 R linkages. Finally, the motion behaviour of the closed cylindrical form of waterbomb origami is investigated through a parametric study, by means of modelling it as a closed network of spherical 6 R linkages. These studies help to deepen the understanding of spatial linkage kinematics and rigid origami motion, and lay the foundation for engineering applications of spatial linkages and rigid origami patterns

Origami has been extensively studied by engineers for its unique motions and ability to collapse to small volumes. Techniques have been studied for replicating origami-like folding motion in thick materials, but limited practical applications of these techniques have been demonstrated. Developable mechanisms are a new mechanism type that has a similar ability to collapse to a low profile. The cylindrical developable mechanism has the ability to emerge from and conform to a cylindrical surface. In this work, a few practical applications of devices with novel expanding motions are presented. The design and testing of an origami-inspired deployable ballistic barrier, which was designed by combining and modifying existing thickness accommodation techniques, is discussed. The properties of cylindrical developable mechanisms are examined and two devices designed for use with minimally invasive surgical tooling are presented. Various hinge options for small-scale cylindrical developable mechanisms are then reviewed and discussed. A planar modeling assumption for curved lamina emergent torsional joints in thin-walled cylinders is then analytically and empirically validated. Conclusions are drawn and recommendations for future work are given.

Bottom-up self-assembly can be used to create structures with sub-20 nm feature sizes or materials with advanced electrical properties. Here I demonstrate processes to enable such self-assembling systems including block copolymers and DNA origami, to be integrated into nanoelectronic devices. Additionally, I present a method which utilizes the high stability and electrical conductivity of graphene, which is a material formed using a bottom-up growth process, to create archival data storage devices. Specifically, I show a technique using block copolymer micelle lithography to fabricate arrays of 5 nm gold nanoparticles, which are chemically modified with a single-stranded DNA molecule and used to chemically attach DNA origami to a surface. Next, I demonstrate a method using electron beam lithography to control location of nanoparticles templated by block copolymer micelles, which can be used to enable precise position of DNA origami on a surface. To allow fabrication of conductive structures from a DNA origami template, I show a method using site-specific attachment of gold nanoparticles to and a subsequent metallization step to form continuous nanowires. Next, I demonstrate a long-term data storage method using nanoscale graphene fuses. Top-down electron beam lithography was used to pattern atomically thin sheets of graphene into nanofuses. To program the fuses, graphene is oxidized as the temperature of the fuse is raised via joule heating under a sufficiently high applied voltage. Finally, I investigate the effect of the fuse geometry and the electrical and thermal properties of the fuse material on the programming requirements of nanoscale fuses. Programming voltages and expected fuse temperatures obtained from finite element analysis simulations and a simple analytical model were compared with fuses fabricated from tellurium, a tellurium alloy, and tungsten.

Lamina emergent mechanisms (LEMs) are a subset of compliant mechanisms which are fabricated from planar materials; use compliance, or flexibility of the material, to transfer energy; and have motion that emerges out of the fabrication plane. LEMs provide potential design advantages by reducing the number of parts, reducing cost, reducing weight, improving recyclability, increasing precision, and eliminating assembly, to name a few. However, there are inherent design and modeling challenges including complexities in large, non-linear deflections, singularities that exist when leaving the planar state, and the coupling of material properties and geometry in predicting mechanism behavior. This thesis examines the planar and spherical LEMs and their relation to origami. Origami, the art of paper folding, is used to better understand spherical LEMs and flat-folding mechanisms in general. All single-layer planar four-bar LEMs are given with their respective layouts. These are all change-point pinned mechanisms (i.e. no slider cranks). Graph representations are used to show the similarities between action origami and mechanisms. Origami principles of flat-folding are shown to be analogous to principles of mechanisms including rules for assembly and motion.

Operational parameters and adjuvants were varied in order to obtain stable enzymes with high activities during storage. The experiments were divided into adjuvant discrimination, optimization of the drying conditions, storage of the raw enzymatic extract (REE) and powders, evaluation of drying on the physical-chemical characteristics of the endoglucanase, and powder morphology. Statistical experimental designs were used to evaluate the effect of the variables exit air temperature, solution flow rate, proportion REE/adjuvant, and total solid content on the enzyme activity retention and powder moisture content. The adjuvant Arabic gum was selected from the discrimination assays. From the optimization experiments, it was determined that the lower flow rate and air exit temperature resulted in the highest enzyme activity retention, while low temperature and solution flow rate resulted in the lowest retention. The total solid concentration was not statistically significant. The powders produced in the Best and in the worst drying conditions were stored at room temperature and under refrigeration and the enzymatic activity was measured at 15 days intervals. The statistical analysis did not show any difference in the enzymatic activity retention after long periods of storage for both drying conditions and both storage alternatives. The influence of temperature and pH on the enzyme activity was also investigated before and after the drying process, and it was noticed that these physical-chemical properties were not affected by the adjuvants and by the drying process. The morphology of the powders, obtained using the inert gas adsorption method, indicated that the powder obtained under the worst drying condition presented specific superficial area twice ...

La dynamique des parois de domaine magnétiques (DW) soulève actuellement un très fort intérêt à la fois du point de vue fondamental mais aussi en lien avec ses applications dans des dispositifs logique et mémoire. Des dispositifs nouveaux basés sur les DW ont déjà été proposés, par exemple présentant des très fortes densités de stockage et des taux de transfert élevés pour un remplacement des disques durs. De plus dans les Mémoires Magnétiques à Accès Aléatoire (MRAM), identifiées comme l'une des solutions les plus prometteuses pour le remplacement des DRAM et SRAM, le retournement de l'aimantation implique une propagation des DW. Le contrôle de la dynamique des DW sous courant est longtemps resté un challenge, principalement à cause d'imperfections dans les matériaux utilisés. Des déplacements rapides et contrôlé des DW au moyen d'un courant ont été reportés il y a quelques années seulement dans des multicouches présentant une asymétrie d'inversion (SIA). Plus récemment un mécanisme a été proposé basé sur la présence de couple de spin orbite (SOT) et de l'interaction Dzyaloshinskii-Moriya (DMI), tout deux trouvant leur origine dans l'interaction spin-orbite et nécessitant une SIA.Mon objectif initial était de tester ce modèle dans deux systèmes présentant différents SIA. Dans des multicouches Pt/Co/Pt à faible SIA, j'ai étudié la propagation des DW sous courant et sous champ et j'ai mis en évidence l'existence d'un amortissement chiral. Ce phénomène nouveau, pendant de DMI pour les mécanismes dissipatifs, influence à la fois la dynamique sous courant et sous champ et doit être pris en compte pour avoir une description complète des mécanismes. Dans des multicouches Pt/Co/AlOx à fort SIA, j'ai étudié de nouvelles géométries pour lesquelles le mouvement de la paroi de domaine et la direction du courant ne sont pas colinéaires. J'ai mis en évidence un déplacement asymétrique des DW en fonction de cette non-colinéarité qui ne peut pas être expliquée avec un modèle simple DMI+SOT. En se basant sur ces résultats expérimentaux, j'ai introduit un nouveau concept de dispositifs, appelé « origami magnétique » : la forme du dispositif gouverne le mécanisme de retournement. Ce concept apporte une grande flexibilité dans la construction de mémoires magnétiques non volatiles, rapides et peu gourmandes en énergie : des fonctionnalités différentes peuvent être obtenues sur un même wafer simplement par la maîtrise de la forme des différents éléments. Je montre la preuve de concept de deux dispositifs<br>Magnetic domain wall (DW) dynamics is currently attracting tremendous interest both from a fundamental point of view as well as in relation with emerging magnetic memory and logic devices. New DW-based devices were recently proposed, for example to replace hard drive disks with higher density and faster date transfer. Moreover, in Magnetic Random Access Memory (MRAM), identified as one of the most promising candidate for DRAM and SRAM replacement, switching occurs through DW propagation. Control of current induced DW dynamics has long been a challenge mainly due to material imperfections. Only some years ago, fast and controllable motions were reported in multilayers presenting structural inversion asymmetry (SIA). More recently, a mechanism was proposed based on the presence of spin orbit torques and Dzyaloshinskii-Moriya interaction (DMI), both phenomena originating from the spin orbit interaction and needing (SIA).My initial objective was to test this model in two systems presenting different SIA. In Pt/Co/Pt multilayers with weak SIA, I studied both current and field induced DW motion and evidenced a chiral damping. This new phenomena, counterpart of the DMI for the dissipative aspects, influences both current and field induced dynamics and has to be taken into account for a complete picture of the mechanism. In Pt/Co/AlOx multilayers with strong SIA, I studied new geometries where the DW motion the and current flow are not collinear. I evidenced asymmetric DW motion as a function of this non-collinearity that cannot be explained with a simple SOT+DMI model. Based on these experimental results I introduce a new device concept named “magnetic origami”: the shape of the device governs the switching mechanism. This concept provides large flexibility to construct fast, low power non-volatile magnetic memory: different functionalities can be achieved on a wafer by simply mastering the shape of the different elements. I show the proof of concept of two such devices

abstract: Origami and Kirigami are two traditional art forms in the world. Origami, from ‘ori’ meaning folding, and ‘kami’ meaning paper is the art of paper folding. Kirigami, from ‘kiri’ meaning cutting, is the art of the combination of paper cutting and paper folding. In this dissertation, Origami and kirigami concepts were successively utilized in making stretchable lithium ion batteries and three-dimensional (3D) silicon structure which both provide excellent mechanical characteristics.<br>Dissertation/Thesis<br>Doctoral Dissertation Materials Science and Engineering 2016

碩士<br>國立中興大學<br>生醫工程研究所<br>105<br>We successfully demonstrate a novel three-dimesnional (3D) origami paper-based analytical device (oPAD) for immunoassay applications. By combining surface modification of the cellulose paper and the slip design, users can easily perform immunoassay in rapid and stable manners. Costly nitrocellulose membrane for affinity biorecognition molecules covalently conjugated is replaced using carboxymethyl cellulose (CMC), N-(3-Dimethylaminopropyl)-N’-ethylcarbodiimide hydrochloride (EDC) / N-Hydroxysuccinimde (NHS) modified cellulose paper. In addition, biorecognition molecules are lyophilized to extend the lifetime and portability of the device during storage and transportation. The results showed that anti-human immunoglobulin G conjugates HRP dried in a variety of sugar matrices retained 80 % of their activity after 75 days of storage at four degrees Celsius. The detection limit of 3D origami paper-based analytical device for Human IgG is 0.1 ng/mL, and the assay results could be visualized in 7 min.

<p>Biological systems have inspired interest in developing artificial molecular self-assembly techniques that imitate nature's ability to harness chemical forces to specifically position atoms within intricate assemblies. Of the biomolecules used to mimic nature's abilities, nucleic acids have gained special attention. Specifically, deoxyribonucleic acid is a stable molecule with a readily accessible code that exhibits predictable and programmable intermolecular interactions. These properties are exploited in the revolutionary structural DNA nanotechnology method known as scaffolded DNA origami. For DNA origami to establish itself as a widely used method for creating self-assembling, complex, functional materials, current limitations need to be overcome and new methods need to be established to move forward with developing structures for diverse applications in many fields. The limitations discussed in this dissertation include 1) pushing the scale of well-formed, fully-addressable origami to two and seven times the size of conventional origami, 2) testing cost-effective staple strand synthesis methods for producing pools of oligos for a specified origami, and 3) engineering mechanical properties using non-natural nucleotides in DNA assemblies. After accomplishing the above, we're able to design complex DNA origami structures that incorporate many of the current developments in the field into a useful material with applicability in wide-ranging fields, namely cell biology and photonics.</p><br>Dissertation

碩士<br>國立臺灣大學<br>機械工程學研究所<br>106<br>In recent years, the use of origami manufacturing methods has gradually become a popular manufacturing method in engineering manufacturing, but at present it has not been used excessively in medical device. The application of origami technology can not only reduce the trauma during surgery, accelerate the recovery of patients&apos;&apos; wounds, shorten recovery time, improve efficiency, but more importantly, reduce medical costs. The idea of using origami to propose medical device will become the future trend of developing medical device. Today, liver cancer is the sixth most common cancer in the world, and the death toll is even ranked third among all cancers. One of the treatments for liver cancer is to use the embolized hepatic artery to block the blood flow to the cancer cells. The most common cause of vertebral compression fractures is osteoporosis. Bone mineral density and strength in the vertebrae are reduced, causing internal fractures of the spine under mild violence and a high degree of decline. The incidence of vertebral compression fractures caused by osteoporosis is high, and it is mainly seen in older women as aging increases year by year. The purpose of this study was to propose the design of medical devices for the treatment of liver cancer and spinal compression fractures by means of origami manufacturing, and to simulate the three-dimensional model structure through software. The manufacture is carried out using a nickel-titanium alloy sheet having shape memory characteristics. For the embolization structure of liver cancer, the heat treatment was used to determine the blocking rate. For the scaffold structure for the treatment of compression fractures, the finite element analysis was carried out first, and the force at the time of compression was measured through experiments. Since the two medical devices are currently in the design test phase, their size is different from the actual size, but the designed device can meet the functions to be achieved by the treatment.

碩士<br>國立臺灣科技大學<br>設計系<br>107<br>The origin of origami has started since 5th century in China. It was a kind of traditional art for children to have fun in their spare time. Later on, the technique has spread by Japanese, transformed and innovated across the island. In 18th century, Japanese origamist Akira Yoshizawa in particular was responsible for a number of innovations, such as wet-folding and the Yoshizawa–Randlett diagramming system. It is not until 1960s that origami has become widespread in the field of mathematics, engineering, design and art, as the technology become advanced. These fields keep growing and evolving together. Using origami as a form of design elements needs to consider the practical aesthetics (function, structure, interface, texture) first. If considering artesian aesthetics (image, context) in design phase, the product will balance between practical and artesian aesthetics. This paper studied several forms of origami and cases from the past to current day. After that, the author experimented several materials for origami, and invented five different form categories of origami, including Pop-up, X Pleats, Twisted Pleats, Twisted Rings, Twisted Columns. Rice papers and PP board were selected as the 3 final works of the material. And then, the author applied V Pleats, X Pleats and Twisted Pleats to the works, which connects origami forms to natural image. Three final works were inspired by nature image, such as phototropism, plants falling in autumn and waves on lake. These images found in nature were turn to 2 lighting designs 【Face The Sun】, 【Come Fall】 and partition design 【Lakeside】 as home decor.

Atualmente, o aproveitamento de excedentes de produção e de subprodutos agro-alimentares é bastante desejável e necessário em termos de sustentabilidade de produção e de consumo. Não obstante, para satisfazer o consumidor, as estratégias de inovação alimentar devem incorporar no seu processo de construção não só as tendências de consumo, mas também a interação direta com o consumidor, percebendo antecipadamente a sua aceitação e potencial comercial. O objetivo principal deste estudo foi desenvolver aplicações gastronómicas com o uso de protótipos de emulsões inversas de origem vegetal, inovadoras, com qualidade sensorial e nutricional, para que se tornem apelativas ao consumidor final. Foram analisadas 5 amostras de emulsões: um creme de barrar de morango, dois cremes de barrar de pimento – pimento amarelo refogado e pimento vermelho assado e dois cremes frutados de mostarda – um de beterraba e framboesa e outro de framboesa e mirtilo. Inicialmente fez-se uma avaliação sensorial, com um painel de provadores e foi utilizada a ferramenta online de Foodpairing®. Após definição do objetivo de cada preparação, desenvolveu-se um receituário com base nos resultados anteriores e também assente no know how gastronómico e culinário da investigadora. Estabeleceu-se um roteiro do menu de degustação e um caderno de prova com parâmetros de aceitação/ intenção de compra/ potencial de comercialização/ utilização. Finalmente realizou-se um teste de aceitação através de um almoço de degustação inserido em restaurante pedagógico, para 40 profissionais do sector alimentar. O painel apreciou positivamente as emulsões mas nenhuma foi apontada como tendo potencial de utilização gastronómica, por si só, mas sim sempre como ingrediente de alguma composição. Obtiveram-se 33 emparelhamentos de ingredientes com a ferramenta de Foodpairing®, que cruzados com a avaliação do painel de provadores conduziram a 34 composições gastronómicas, que foram desenvolvidas em oficina culinária. No almoço de avaliação, foi o creme de pimento amarelo o mais apreciado e o de morango o menos apreciado globalmente. Em relação às iguarias desenvolvidas e apresentadas, todas tiveram apreciação positiva. Na intenção de compra houve um incremento substancial para a maior parte das amostras, após degustação das iguarias confecionadas com os mesmos: a maior parte dos provadores compraria os cremes analisados e vê potencial de comercialização em todas as emulsões. A opinião dos chefs foi bastante importante e útil, mas nem sempre coincidente com os ingredientes propostos pela aplicação de Foodpairing®. A avaliação sensorial e o teste de consumidor demonstraram que o desenvolvimento de aplicações culinárias, após a inovação de produtos é deveras importante, pois pode resultar na aceitação ou não do produto pelo consumidor final, seja ele pertencente ao Food Service ou sendo consumidor doméstico. A inovação global implica aceitação pelo consumidor e educação de aplicação gastronómica, situação evidenciada com o teste de aceitação realizado.<br>Currently, the use of surplus production and agro-food by-products is very desirable and necessary in terms of production and consumption sustainability. Nevertheless, in order to satisfy the consumer, food innovation strategies must incorporate in their construction process not only consumer trends but also direct interaction with the consumer, anticipating their acceptance and commercial potential. The main objective of this study was to develop gastronomic applications with the use of water-in-oil inverse emulsion prototypes, innovative, with sensory and nutritional quality, so that they become appealing to the final consumer. Five samples were analyzed - 3 emulsions of strawberry and pepper (red and yellow) processed differently, with aqueous vegetable phase and 2 mustards with red fruits or beet. Initially a sensory evaluation was carried out with a panel of tasters and the online Foodpairing® tool was used. After defining the purpose of each culinary preparation (entry, main course, dessert, for Food Service or domestic end consumer), a recipe set was developed based on previous results and based on culinary know-how, creative/ aesthetic talent of the researcher. A script of the tasting menu was established, and also a test book with parameters of acceptance/ purchase intention/ marketing/ use potential. Finally, an acceptance test was carried out through a tasting lunch inserted in a pedagogical restaurant for 40 professionals from the food sector. The panel positively evaluated all emulsions but none was pointed out as having potential gastronomic use by itself, to be used alone, but always as an ingredient of some composition. There were 33 combinations of ingredients with the Foodpairing® tool, which, cross-checked with the panel of tasters, led to 34 gastronomic compositions that were developed in a culinary workshop. At the evaluation lunch, the yellow pepper emulsion was the most appreciated and the strawberry was the least appreciated globally. In relation to the delicacies developed and presented, all had positive appreciation. For the intention to buy there was a substantial increase after tasting the delicacies made with them: most tasters would buy the creams analyzed and see commercialization potential in all emulsions. The opinion of the chefs was quite important and useful, but not always coincident with the ingredients proposed by the application of Foodpairing®. Sensory evaluation and consumer testing demonstrated that the development of culinary applications after product innovation is very important because it can result in the acceptance or not of the product by the final consumer, whether it belongs to the Food Service or is a domestic consumer. Global innovation implies acceptance by the consumer and education for the gastronomic application, situation evidenced with the consumer test that was realised.
