Design Process
Design Process
The design was based on a slider-crank mechanism with three flexible joints known as lamina emergent compliant hinges. These joints are modeled as springs in the upper left in the figure on the right in accordance with the Pseudo-Rigid-Body Model (PRBM). The PRBM provides a simple method to analyze conservative systems that undergo large and non-linear deflections. This system has one degree of freedom, which is essential to keeping the mechanism’s motion reliable and user friendly.
Iteration
Iteration
Additive manufacturing made it easy to iterate between different LEM joint designs. PLA proved sturdy enough for researchers to test the prototypes with their bodyweight. Magnets created a fastening method which made it easy to switch the mechanism from a flat to high heel state while keeping the mechanism stable in that state. The motion of our deployable heel design was analyzed with simulation via SolidWorks FEA and analytically via MATLAB.
