Description
This work presents methods for using membrane joints in origami-inspired mechanisms. Our method takes the previously presented hinge ideas of the Regionally Compliant Sheets (ReCS) method and the Compliant Rolling Contact Element (CORE) joint, and builds upon them to provide a hinge that has the benefits of being adhered between sheets using clamping with no adhesive needed, preserving panel volume that can be used as hard stops, and keeping the stress in the bending membrane below the yield stress, while reducing the parasitic motion of previous membrane joints. Two different configurations are presented: The Contacting Circles Embedded Membrane and the Enhanced ReCS. These two configurations are described for a planar, single-folding mechanism. A comparison between methods is presented, focusing on the axial parasitic motion of each configuration. Each configuration was also applied to a degree-4 origami vertex with a discussion of the benefits of each.
