Abstract
Recent interest in origami-based engineering design has illuminated opportunities for new products and has also introduced and many challenges. One such challenge is the inability to fold thick-sheet engineering materials using crease patterns which assume zero thickness. Several approaches have been developed which assist in accommodating the thickness of materials. Introduced in this work is a unique method to accommodate the thickness of materials in origami engineering without the need for assembly of its panels and joints. This fabrication out of monolithic thick-sheet materials is viable due to the incorporation of compliant mechanisms formed from the sheet. A general approach to apply the proposed method is described. An optimization of joints is used due to interference at a vertex. The thickness accommodation method and optimization are applied to a simple degree-four-vertex crease pattern in detail. As further proof of concept, the method is demonstrated on an origami square-twist crease pattern.
