Para tal, são consideradas três principais vertentes: 1) investigar o estado da arte do origami, desde o seu surgimento histórico até a evolução cronológica de pesquisa científica, processos de comunicação e segmentos estéticos; 2) analisar diferentes publicações do design do origami, as técnicas envolvidas e áreas de atuação; 3) desenvolver estudos de caso em prototipagem baseados no material estudado. Através do método indutivo-confirmável, o estudo possui dois momentos: pesquisa teórica bibliográfica e pesquisa prática experimental. O estudo teórico baseia-se na leitura e seleção de artigos de periódicos, publicações de congressos e livros que elucidem as diferentes possibilidades de ação projetual das dobraduras como a técnica do crease pattern e as vertentes do design de origami adaptado. O estudo experimental trata-se da construção de protótipos para a comprovação prática das técnicas e segmentos estudados. O objetivo de pesquisa está na compreensão da importância do design de origami em diferentes áreas do conhecimento teórico e aplicado e como as dobraduras são reapropriadas para gerar novas formas de construção e modelagem com os materiais e estruturas. Busca-se uma contribuição geral no sentido de solidificar mais e melhor os conceitos e pesquisas com o design do origami no Brasil. / The present research aims to investigate the projetual and scientific role that origami, folding paper art, is performing globally and how folds design can contribute to the creative process and to technological innovations. To this end, three main aspects are considered: 1) to investigate the state of origami’s art, from its historical emergence to the chronological evolution of scientific research, communication processes and aesthetic segments; 2) analyze different publications of origami design, the techniques involved and acting areas; 3) to develop case studies with prototyping based on the material studied. Through the inductive-confirmatory method, this study has two moments: theoretical bibliographic research and practical experimental research. The theoretical study is based on reading and selection of articles from journals, congress publications and books that elucidate the different possibilities of folds design as crease pattern technique and origami-adapted design. The experimental study is based on prototypes construction for practical verification of techniques and segments studied. The research objective is to understand the importance of origami design in different areas of theoretical and applied knowledge, and how foldings are reappropriated to generate new forms of construction and modeling with materials and structures. A general contribution is considered to solidify more and better the concepts and researches with origami design in Brazil.

This work evaluates a specific origami device known as the kaleidocycle and the broad classof rigidly foldable origami. Both of these have potential for application in the design of deployableand foldable arrays of spatial mechanisms.Origami is considered a compliant mechanisms because it achieves its motion through thedeflection of paper creases. Compliant mechanisms generally do not allow for continuous rotation;however, the compliant kaleidocycle represents an exception to this generality. Along with theirability to rotate continuously, kaleidocycles may also be designed to exhibit multistable behaviorduring this rotation. These two characteristics make the kaleidocycle an interesting device withpotential for applications in engineering. This work presents the multistable characteristics ofkaleidocycles, showing that devices can be made which exhibit one, two, three, or four distinctstable equilibrium positions. Kaleiocycles may also be designed to exhibit a range over which thedevice is neutrally stable.The second type of origami presented in this work is rigidly foldable origami, a special classof origami in which all deflection occurs at the creases, allowing the panels to remain rigid. Thistype of origami is of particular interest because of its ability to be constructed from materials muchstiffer than paper while retaining its mobility. This property allows rigidly foldable origami to beapplied to fields such as architecture and deployable mechanisms. This work presents a method forevaluating rigid foldability in origami tessellations. This method is used to define seven theoremsfor the rigid foldability of origami twists and to develop new rigidly foldable origami “gadgets”and tessellations.
