In origami engineering, folds are precisely designed to impart desired mechanical properties and functionalities to the material. Folds can be sharp or smooth, single or multiple, and arranged in various patterns to achieve different structural configurations.
Unfolds: Unfolds are the reverse of folds, where a folded structure is flattened or deployed into a different shape. Unfolding mechanisms are crucial for applications such as deployable structures and self-assembling systems. Origami engineers carefully design crease patterns and material properties to enable controlled and reliable unfolding.
Crease patterns: Crease patterns are the arrangements of folds and unfolds that define the geometry and behavior of an origami-inspired structure. These patterns determine the overall shape, strength, and flexibility of the structure. Origami engineers utilize mathematical and computational techniques to design crease patterns that result in structures with specific properties and functionalities.
The interplay of folds, unfolds, and crease patterns allows origami engineers to create structures with remarkable properties, such as lightweight, strength, compactness, and adaptability. These structures find applications in diverse fields, including aerospace, architecture, robotics, and biomedical engineering.
