abstract

Consideration of a product’s manufacturability is a vital aspect of product design. When considering manufacturability of panels for origami-adapted products, there are trade-offs between panel design approaches as well as thickness-accommodation techniques. The use of bent sheet metal for panels shows promise as a panel design approach that mitigates several of these trade-offs. This paper describes a process that can be employed to use sheet metal in designs of origami-adapted mechanisms that utilize specific thickness-accommodation techniques. The process is demonstrated for a square-twist mechanism designed using the hinge shift technique for accommodating thickness in origami patterns. A Miura-ori mechanism is also shown in sheet metal. The characteristics of these bent panel approaches are discussed and compared to other approaches for designing panels for manufacturing. The use of bent sheet metal panels allows for mitigation of several trade-offs and shows the applicability of origami-adapted design to sheet metal.
