Design method of uniform convex polyhedron device with variable volume

The invention discloses a design method of a volume-variable uniform convex polyhedron device, which comprises the following steps of: constructing each surface of a uniform convex polyhedron by using plane hinging and embedding, applying a force of which the centroid points to the vertex direction on the vertex of each surface, and simultaneously unfolding each vertex at the same speed, so as to obtain an expandable body design method with innovativeness and systematicity. According to the method, a series of uniform convex polyhedrons with variable volumes can be quickly constructed. Due to the characteristics that the uniform convex polyhedron is highly symmetrical and each surface is a regular polygon, the uniform convex polyhedron has a wide application scene in actual work and life. The design method is simple in form, does not need an additional frame, has the technical advantage of volume expansibility and artistic expressive force, and has high application potential in the fields of artwork design, m
