A reconfigurable joint based on extruded polyhedrons

An extruded polyhedron is a reconfigurable geometric shape based on the extrusion of each surface of a polyhedron along the normal direction. This paper introduces an extruded polyhedral joint that uses its own spatial structure to generate multiple states. The component primarily consists of an extruded polyhedron and is equipped with an optional adaptor to adapt to various situations. This research proposes that the formal deformations of a partially extruded polyhedron due to the instability of its own structure give it potential as a reconfigurable joint. To cope with the inevitable deformation of the extruded polyhedron branch cross-section during the overall deformation process, an adaptor - an indispensable component of the entire joint - is utilized at strategic branch locations. In addition, the reconfigurable methods and internal structure of the joints are discussed in detail. Finally, some practical application scenarios for connection components and their advantages in application scenarios are introduced.
