Electric Hinge Assembly

Fathom Make The Unmakeable Challenge #2 - Runner Up The Electric Hinge Assembly takes advantage of additive manufacturing technology by using fasteners designed to be printed in place, https://grabcad.com/library/rotational-lock-fastener-1 , https://grabcad.com/library/zip-shoulder-fastener-1 resulting in a reduction of manufacturing costs and assembly time. The first hinge assembly pictured can be printed today using a single print material, but must be disassembled in order for four conductive concentric rings with leads to be installed (Pictured in Red And Green). The Rotational Lock Fastener holds the conductive surfaces in contact. The second hinge assembly was designed with future print materials in mind. Once a conductive print material hits the market, the real benefit of additive manufacturing and the Electric Hinge Assembly can be realized. The entire assembly can be printed in a single run with support material between the two conductive surfaces. After the support material has been removed the two conductive surfaces can freely rotate. The Electric Hinge Assembly is a very flexible design that can be implemented in a number of applications. It could be installed in a refrigerator door to supply input and power to a touch screen or your home's front door to provide uninterrupted power to the smart lock just to name a few. With the rise of wearables, the hinge can be scaled down and used in watches and glasses to provide articulation between the sensor and battery. Benefits: The hinge has full 360 degrees of rotation, maintains contact between the conductors even after wear, can be used for power or signal, and can be printed preassembled in place, Technology: FDM Material: Assembly 1( Gray - ABS, Red & Green Copper Conductor) Assembly 2 (Gray - ABS, Yellow - Conductive Additive Material) ABS was selected because it will act as an insulator when paired with conductive materials.
