Surrogate Fold Hinges: Replacing Paper Folds in Origami

Year: 2023

Presenter Name: Phebe Ramsdell

Origami has been practiced for generations, but only recently have we seen relevant usage of this art form emerge in technological applications. These applications have been found in space arrays for a compact design during space travel, uses in the biomedical world for surgical technology, and can even be utilized in safety products such as a Kevlar ballistic barrier, an easy set up bullet proof shield for police officers. With applications, comes the need for designers and manufacturers to consider specific hinges used for unique origami-based mechanisms. A traditional hinge will come with complications as enhanced complex mechanisms come into play. Therefore, compliant hinges are most advantageous concerning problems such as thickness accommodation and fabrication. Differing materials create difficulty because it may add flexibility or stiffness in the mechanism which will affect how the surrogate folds bend. With the help of current technology, we have researched existing surrogate fold joints that could be used as compliant hinges. Using this research, we are creating a surrogate fold characterization database. This tool will give designers the chance to consider the properties of their origami-based mechanism during the design stage, then use the database to select hinges that will fit their specific criteria. This surrogate fold characterization database will cut out time spent testing folding motion with a prototype. It will grant the engineer an efficient tool of determination, in which they can choose a compliant hinge that optimizes the function of their origami-based mechanism.
