罟坶是一种新的建筑结构,更可以说像一种活的物体。一般意义上的建筑物都是死的,静止的结构,而罟坶是活的。就像一个有灵活关节的骨架一样,这同时也意味着罟坶不可能完美的稳定。事实上罟坶是可以和体验者在互动的时候摇摆和晃动的。它的表皮会缓慢变化拉扯和收缩,骨头会发出咯吱的响声,它的触须会颤抖。罟坶可以根据任何环境生成出合理的结构站立起来。
 
结构创新在于节点,节点创新在于材料。我们对橡胶、硅胶、木头、纸管等一系列材料进行测试,设计了不同形式可动的灵活节点。由木头制作出来的灵活节点脆性很大,可承受的扭力很小。最终选择了浇铸硅胶制作成的软性节点。硅胶相较于橡胶更加柔韧,并且与纸和木头的吸附性更强。纸管比木头要轻得多,这就可以大大减少整个结构的自重,从而减少建成后整体结构的下沉。更有利的是,因为纸管是中空的,我们可以把互动的电子元件隐藏在里面。但是,中空纸管的接触面却是有限的,不足以和硅胶形成强度高的连接。因此我们设计了另一种零件-木质暗榫-来抓紧纸管和硅胶,更有效的提高了节点的力学特性 
  
罟坶结构是一个使用标准化节点的参数化结构。罟坶结构系统中有三个主要结构成员。穹顶层是用标准化节点连接不同长度的纸筒预组装完成的。底部基础使用的是固定在地面的,被弯折到固定角度的铝管。在场地上的搭建过程,加入支撑结构使整个结构站立起来。
  
Gume is a new type of architectural structure, which has more in common with a living creature than a building. Whereas most buildings seem to be dead, static structures, Gume is alive! Like a skeleton its joints are flexible, which means that Gume is never perfectly stable. In fact, Gume will wiggle and wobble as users interact with it. Its skin will crawl, bones will rattle, and hair will stand on end. Gume makes its monstrous come on the stage in any condition!
 
The innovation of the structure lies on the joint, while the innovation of the joints lies on the material. We did a series test on rubber, silicon, wood and paper tubes and continuously improve the design of flexible joints. According to the test, rubber is not very stick to the wood, so the torsional strength is weak. Silicon is softer than rubber and performs well with wood and paper tubes. Paper tubes are much lighter than wood sticks. It will significantly reduce the subsidence of the whole structure. Further more, because it is hollow, we can hide the interaction electronic device inside. However, the contact surface of hollow paper tube is not enough to make strong connection with the silicon. Therefore, we designed a component - a dowel - to firmly grasp the tube and silicon.
 
Gume structure is a parametric system using prefabricated standard joints. There are 3 structural members in the system. The main cover sheet of the canopy is pre-assembled by standard joints linking the tubes in different lengths together. The foundation of the structure is fixed aluminum pipe bent in fixed angles. To make the canopy stand, the bracing members are added on in the construction on site.
