CAD ratchet mechanism prototype to hold the spring's potential energy.
The aim of the prototype is to hold and store the potential energy in the spring. The storing the energy work by turning the ratchet. The ratchet gets turned when the user squats down. The mechanism supports the user's downward motion when squatting, whilst storing the reactive force perpendicular to the ground. The ratchet is locked to turn on one direction by the pawl. The servo motor pull/releases the pawl from the ratchet via wire, enabling the freedom movement of the ratchet to turn the opposite direction.
