gefold

GeFold is a term used to describe a conceptual framework and set of methods for designing and analyzing the folding of geometric structures. Encompassing elements of computational geometry, origami mathematics, and materials science, gefold aims to transform flat crease patterns into three-dimensional forms while accounting for physical constraints such as material thickness, crease accuracy, and mechanical stability.

Core problems in gefold include selecting crease networks, planning feasible sequences of folds, and predicting the final configuration under elastic deformation. The approach often combines formal theorems from origami—such as Kawasaki’s and Maekawa’s criteria for flat-foldability—with optimization techniques that minimize energy, actuation effort, or structural stress.

Applications of gefold-inspired methods span deployable structures and lightweight engineering (such as space deployables and portable shelters), soft robotics, architectural façades, and packaging design. In research settings, gefold serves as a bridge between abstract crease-pattern theory and practical fabrication, enabling simulations that guide material choice and scoring patterns.

Limitations include sensitivity to material thickness, fabrication tolerances, and the complexity of real-world dynamics. Ongoing work seeks to improve predictive accuracy, scale to larger systems, and integrate gefold pipelines with computer-aided design and manufacturing workflows.
