| description | This report investigates alternative designs to replace the Boa lacing system in lower limb prostheses, addressing the limitations of existing tightening mechanisms. By adopting a different approach to prosthetic securing, this research aims to enhance comfort and adjustability for users. One of the primary challenges in prosthetic socket design is accommodating the variable size of the patient's residual limb stump, which, compounded by the socket's rigid structure and inadequate ventilation, can lead to ulceration. Drawing on principles from mechanical design, material science, and ergonomic considerations, the report details the ideation, prototyping, and testing phases of the new mechanism. Leveraging computer-aided modelling and 3D printing technology, rapid iterations and improvements are made based on testing outcomes and user feedback. The project targets the development of a lightweight, adjustable, and well-ventilated prosthetic specifically tailored for a 77-year-old male amputee weighing 76.6kg and standing at 166cm tall, with a transtibial amputation. The innovative design features a spring mechanism to ensure a secure fit and continuous adjustability throughout the prosthetic's usage. The kinematics result shows some similarity in motion from the left foot however there is still much to improve on. |
