柔性杯垫-可变形--双稳态结构/Flexible coaster - deformable - bistable structure

柔性杯垫-可变形--双稳态结构/Flexible coaster - deformable - bistable structure    看到一种很有趣的结构--双稳态结构：指具有两个稳定平衡状态，且能在无能量输入条件下维持稳定性的机械或材料系统。这类结构的特点是存在两个能量最低点，通过外部触发可切换状态，并依靠自身特性保持稳定。     其基本构成一眼看上去就应该是杯垫，所以做了出来，各部件转轴需用耗材丝穿起来， 杯垫有打开和闭合两种大小，可用于不同大小的杯子 I see a very interesting structure - bistable structure: refers to a mechanical or material system that has two stable equilibrium states and can maintain stability under no energy input conditions. The characteristic of this type of structure is the existence of two lowest energy points, which can be switched through external triggering and maintain stability through their own characteristics. Its basic structure should look like a coaster at first glance, so it was made, and the rotating shafts of each component need to be threaded with consumable threads, The coaster comes in two sizes, open and closed, and can be used for cups of different sizes
