Ortho-Planar Spring

This design was developed by the Compliant Mechanisms Research Group (CMR) from Brigham Young University (BYU). To learn more about compliant mechanisms, see the [BYU Compliant Mechanisms Research (CMR)](https://compliantmechanisms.byu.edu/) website.

The Ortho-Planar Spring is a compact spring with a platform that undergoes a large displacement in either direction, but does not rotate like conventional planar springs. This invention has numerous advantages.

Compact: this planar spring is much more compact than traditional helical springs.
No rotation: unlike conventional-planar springs, the center of this spring does not rotate relative to the base perimeter of the spring.

Large deflections: this spring has the potential for larger deflections than conventional planar springs.

Low cost: the planar nature of this spring allows for low-cost sheet manufacturing processes.

Reduced wear and noise: because the platform does not rotate or slide to rub adjoining parts, there is
