Abstract
We propose a method to create reconfigurable joints, where reconfigurability entails that a set of components can be connected in multiple ways. The advantage of this type of joint is the possibility of efficiently reusing limited components for multiple purposes. In established carpentry practices, a popular reconfigurable joint geometry called Kawai Tsugite has two components that can be reconfigured in different orthogonal angles. However, the general geometric requirements for the design of reconfigurable joints have not been defined previously. We clarify the conditions for reconfigurable joints from the perspective of symmetry-based geometry repetition and provide guidelines for constructing multi-component joints and for ensuring stability. Moreover, we present a system that assists in the design of voxel-based reconfigurable joints and use it to fabricate several stable reconfigurable joints.
