Abstract

The radial folding ratio of single-vertex multi-crease rigid origami, from the folded configuration to the unfolded configuration, is satisfactory. In this study, we apply two approaches to add non-zero thickness for this kind of origami and identify the different geometrical characteristics. Then the model of the secondary folding origami, which can help to further decrease the folding ratio, is constructed. We apply the method of constraining the edges of the panels on prescribed planes to geometrically obtain the kinematic model. Based on the kinematic model and the screw theory, the non-zero thickness origami is transformed into the deployable mechanism with one degree of freedom. Other similar mechanisms can be derived based on this basic configuration. The computer aided design examples are presented to indicate the feasibility.
