Traditionally, most of the mechanically driven systems utilize contact-dependent approaches. They have hosts of defects, including the need for lubrication to minimize friction, noise management, and a restricted operating life. The magnetic augmentation of existing devices within a mechanical system can resolve these issues by introducing a near-contactless method of operation. The design in focus is fundamentally a piston-styled shock absorber that is capable of generating energy as a product of applied force. The system absorbs shock in two separate manners. The first is due to a series of repelling magnets oriented on two separate plates that oscillate in closeness depending on the applied force. The second is via the internal section of the piston, where an incompressible fluid is forced to flow through small holes in a magnetically fitted oscillating plate. By placing multi-layered, enameled copper coils surrounding the magnets’ direction of translation in both methods of shock absorption, electric currents can be generated thus inducing passive energy generation as a product of shock absorption. In addition, this system is constructed to be variably recursive; in essence, any number of devices can be oriented, so they perform together with small variations in structure depending on the location of each device. The current prototype focuses on a vertically recursive model for applications concerning constrains in a horizontal surface area.
