Publication number: 20150342050Abstract: An origami enabled manufacturing system. The system uses origami design principles to create functional materials, structures, devices and/or systems having an adjustable size and/or shape. An operational device can be coupled to a planar substrate shaped and sized to correspond to a desired origami shape of an origami pattern. A plurality of planar substrates can be coupled together by a plurality of connection members that corresponds to one or more crease of the origami pattern. An array of planar substrates can be formed that convert into a three dimensional structure with origami shape. The resulting three-dimensional structure provides smaller projection area, higher portability and deformability.Type: ApplicationFiled: January 15, 2014Publication date: November 26, 2015Inventors: Hanqing Jiang, Hongyu Yu, Goran Konjevod, Yong Xu
