Spring Loaded knee brace is a medical device designed to support and protect the knee and is used for treating knee injuries and helps to relieve the pain in chronic conditions like arthritis.

This case study is made to resolve the problem that was identified in my research. The best way to solve the problem is to first identify and define the problem.

Here is the Problem: Knee brace require a mechanism that should use the spring force for levitation and this spring assistance can be adjusted precisely as the patient chooses to have without compromising the full range of motion of the knee joint.

Initial Brainstorming and design sketches were made to understand and to illustrate the mechanics. Analyzed if this mechanism is solving the problem defined. Sketches shows the preliminary understanding of how the product should look like so I prefer to draw them by hand.

Product design and modifications were completed, and I did a final refinement to document the product is meeting the design intent specified and furthermore dive deep into the detailing of the design. Entire product is designed keeping the patient comfort in mind. A unique mechanism is incorporated to precisely control the spring force output by adjusting the controller mounted on the side of the brace. This allows the patient to adjust the spring assistance as they wish to have and this can be done even when they are sitting on the chair and without even compromising the range of motion which the patient loves to have.
