Our product is designed to be an adjustable, one-size-fits-all prosthetic that fits a wide range of users with different size arms and amputation site locations. The product’s adjustable length and connection point allows us to manufacture one design, instead of producing custom fitting prosthetics for each user. This reduces the need for a professional to scan and fit prosthetics for each user and allows our product to be mass produced – reducing the cost to our customer. The product itself is adjustable in length and in attachment location. The arm is designed as two concentric ellipses that can be fastened together at different heights to adjust the length of the arm to the user. The attachment strap and cushion can similarly be fastened to different locations along the arm to better fit users with different amputation locations. The hand is powered by long-lasting, rechargeable batteries that power four servo motors that pull the fingers to grip. User-friendly controls allow the hand to pinch and perform multiple holding grips with varying force. Overall, our product is designed to be a cost-effective, easy to use solution that will appeal and provide functionality to a wide range of amputees.
