Abstract
A system and method for a transportation device that utilizes an alternative biomechanics framework for the human lower body that may be used in any transportation vehicle in conjunction or as an alternative to wheels whereby the bones, muscles, and connective tissue of the lower body function together to produce the mechanics of a single wheel rather than the conjoined pendulums of the leading inverted pendulum model of biomechanics.
Claims8
A transportation system comprising:
- two foot spiral devices, each forming a single segment of a three-dimensional log spiral, wherein each spiral device comprises:
- component parts with torsion spring functionality;
- capability for inversion, clenching and abduction movements;
- a tread hub comprising two or more ankle-like joints;
- a shaft comprising two lower leg-like devices connecting the tread hub with a wheel hub, wherein the wheel hub comprises two knee-like joints;
- and
- an axle comprising two upper leg-like devices connecting the wheel hub with a pelvis-like device, wherein the pelvis-like device has two hip-like ball-and-socket joints and a swivel seat-like device that rotates back and forth elliptically around an attachment point.

A method for a transportation system, the method comprising:
- winding a first foot-like spiral device by inverting, clenching, and abducting it during a swing phase;
- simultaneously unwinding a second foot-like spiral device by everting, unclenching, and adducting it during a stance phase;
- translating torque generated at a tread hub to a pelvis-like device via a virtual shaft, wheel hub, and axle;
- rotating a swivel seat-like device back and forth elliptically around an attachment point while maintaining vertical and mediolateral stability;
- and
- repeating the winding and unwinding processes with the first foot-like spiral device and the second foot-like spiral device reversed to complete a full cycle of movement.
