Zusammenfassung

The term “origami” is usually associated with the outcome of a given folding process rather than the process itself. Once we focus on the folding, every piece of origami becomes a (more or less intricate) mechanism and can provide awealth of inspiration to efficiently design kinematic structures from flat sheets. A critical point for origami-based structures made for real-world applications that need to be produced from thicker materials is the availability of practical hinge concepts that need to meet several requirements, including ease and economy of manufacture, robustness, and longevity. Compliant hinges show promise with regard to these requirements. Recently introduced plastically annealed lamina emergent origami (PALEO) combines this concept with non-trivial programmable states to which agivenstructures will return elastically without any additional actuators or external stimuli.This paper explores the potential of PALEO structures intended for use as facade elements, which are one focus of the Collaborative Research Centre 1244 ”Adaptive Skins and Structures for the Built Environment of Tomorrow” at Stuttgart University. Issues of design, manufacturing, scalability, longevity and feasibility of origami-inspired structures in an architectural context will be addressed and augmented by data gathered from finite element analysis and real-world mechanical testing of selected structures.
