为什么值得看
1985年被设计竞赛拒绝的三向拉链专利，经MIT CSAIL团队重新开发，实现物体在柔软与刚性结构间切换。对机器人抓取、可穿戴外骨骼等需要自适应刚度的场景有直接工程价值。
编辑判断
这个设计的真正价值不在拉链本身，而在它提供了一种极低成本的机械式刚度切换方案。目前可变刚度执行器（VSA）主流方案依赖气动、形状记忆合金或低熔点合金，要么需要气源要么响应慢。Freeman的拉链结构纯机械、可手动或电机驱动、断电保持状态，这在灾区救援机器人或太空展开结构中可能是更可靠的方案。CSAIL团队下一步需要验证的是循环寿命和负载重量比，以及能否用现代复合材料替代原型的金属齿来减重。

Not a mechanical engineer, but I'd figure both the "rigid" and "load-bearing" aspects will be far poorer than conventional beams of the same size an
Depends on the material that is being used and application. I could see this being highly useful for tents and similar fabric structures. I probably would not build a satellite solar panel structure/frame with them (atomic oxygen is a nasty critter) but for some lightweight terrestrial applicat
Interesting, which material?
