折纸技术，如折叠和展开，可以用于收缩结构。特别是当折痕图案是刚性可折叠时，可以将其视为由铰链连接的刚性板的机械连杆。由于刚性可折叠折痕图案具有刻面不能拉伸或弯曲的强烈几何约束，设计新的折痕图案难度很大，现有图案的变化有限。然而，众所周知，有一些情况下，折痕图案可以通过添加一些狭缝来使其刚性折叠。本文提出了一种通过增加缝隙折叠成类似平面形状的机械连杆机构。提出了一种在折叠较小的任意多边形中生成刚性可折叠折痕图案的方法，并证实了由这些折痕图案可以通过使用刚性厚板和铰链来生成具有收缩机制的结构。
Origami techniques, as folding and unfolding, can be utilized in shrinkable structures. Especially when the crease pattern is rigid foldable, it can be treated as a mechanical linkage of rigid panels connected by hinges. Since rigid foldable crease patterns have the strong geometrical constraint of the facets not being able to stretch or bend, it is difficult to design new crease patterns, and variations of existing patterns are limited. However, it is known that there are cases where crease patterns can be made rigid foldable by adding some slits. This paper proposes a mechanical linkage that folds into a similar flat shape by adding slits. A method is presented of generating rigid foldable crease patterns in arbitrary polygons that fold smaller, and it is confirmed that structures that have a mechanism for shrinking can be generated from these crease patterns by using rigid thick panels and hinges.
