Abstract Origami-based structures have been widely implemented in the design of deployable systems. They possess desirable properties such as easiness in manufacturing, high transportability, programmability, and the capability to fold into complex three-dimensional (3D) structures starting from planar configurations. However, their geometric complexity poses major challenges in developing efficient design methods, in which optimizing their geometries and folding motions remains a challenging task. This paper investigates the motion and shape inverse design of a Miura-based origami deployable system for architectural applications. The proposed structure folds from a flat to different 3D shapes, has 1 degree of freedom, and can fold rigidly being also flat foldable. The capabilities of the structure to fold approximating symmetrical target shapes of different geometries and achieve tailored folding motions are investigated. Furthermore, an inverse computational design workflow is proposed. The structure showed good accuracy in approximating target shapes, folding within desired motion envelopes, and avoiding collisions with surrounding objects. The origami-based system could be designed to deploy in different scenarios at the architectural scale, and could find applications as deployable canopy for improving comfort in outdoor conditions. Although limited to early design stages, the proposed design workflow is a flexible tool that could be applied to shape and motion inverse design tasks by simply variating its objective function. The method could be further applied to different typologies of rigid-foldable origami-based structures at different scales. |
