Mobix: trastibial leg

This project introduces the development of a transtibial prosthetic leg designed to improve the quality of life for individuals with below-knee amputations, particularly those engaged in self-employment or home-based work. The design focuses on addressing the unique needs of users who rely on mobility for everyday productivity while requiring a prosthesis that is comfortable, lightweight, and easy to maintain. The prosthesis is constructed using a titanium pylon, offering superior strength and corrosion resistance with minimal weight. A carbon-fiber reinforced, 3D-printed socket provides a custom fit tailored to the user's limb, optimizing pressure distribution and reducing skin irritation. For foot mechanics, a carbon-fiber composite spring blade is employed to simulate the energy return and fluid motion of a natural human gait. To enhance comfort during long hours of wear, a ventilated cosmetic cover is integrated, promoting airflow and reducing heat buildup inside the socket. An adjustable knee joint is incorporated to provide enhanced mobility during walking, sitting, and standing—accommodating the varying postures and activities common in small-scale work environments. The modular design also ensures that components can be easily replaced or adjusted for individual needs. This user-centered design demonstrates how thoughtful integration of materials, structure, and function can result in a prosthetic leg that is not only biomechanically effective but also tailored for real-world usability. It reflects a balance between medical functionality and daily lifestyle support, promoting both physical mobility and economic independence.
