The motivation of this research was twofold: to (1) develop a method for designing origami-based devices with multiple stable fold states, and (2) help engineers identify which stability techniques would be best for their application. This paper presents the Origami Stability Integration Method (the OSIM), an 8-step design method to help engineers achieve single or multiple stable positions in origami-based products. The OSIM helps the designer visualize how the different existing loads affect the movement of the origami-based device. Existing stability techniques are categorized to help the designer select appropriate techniques for their specific application, and a number of origami-based design considerations and resources related to stability are also included. The categorization is partially derived from a study of 69 origami-based products that were evaluated to determine which techniques are being used in products and how often they are used. Case studies of an origami-based anti-buckling guide for a medical catheter and an origami-based ballistic barrier are presented.
