COLLAPSING PIPE
The collapsing pipe utilizes three levels of product models derived from two triangular plane part models and one axial framework part model. As the controlling angle is reduced from 180° to 130°, the planar assembly contracts inward, with each connected element perpetuating the resultant curve.
The inspiration for this product model came from a piece of origami called the magic ball:
My attempt at replicating the basic structure and folding action:
The first product level is made from a series of triangular parts constrained by the driving angle (shown at 129°), and coincidences to two axial frameworks. These constraints allow the entire product to move relative to the single driving angle. Two more product levels are used to aggregate these products into the final result.
