折纸技术，如折叠和展开，可用于收缩结构。特别是当折痕图案是刚性可折叠的时，它可以被视为通过铰链连接的刚性面板的机械连杆。由于刚性可折叠折痕图案具有小平面不能拉伸或弯曲的强几何约束，因此难以设计新的折痕图案，并且现有图案的变化受到限制。然而，已知存在通过添加一些狭缝可以使折痕图案刚性可折叠的情况。本文提出了一种机械连杆机构，折叠成一个类似的平面形状，通过添加狭缝。本文提出了一种在任意多边形中生成刚性可折叠折痕图案的方法，该方法折叠得更小，并且证实了可以使用刚性厚面板和铰链从这些折痕图案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 using rigid thick panels and hinges.
