| Abstract: | Despite a growing global demand for prosthetic care, only 5–10% of individuals who could benefit from prosthetic devices currently have access to them. This disparity underscores the need for prosthetic solutions that are not only affordable and functionally effective but also adaptable to users' diverse needs. Amputees continue to face physical, psychological, and social challenges that impact their quality of life on a daily basis. In response to this need, Gyromotics introduced the Nova foot, a dynamic, high-performance, and cost-effective prosthetic foot designed for active lower-limb amputees (K2–K4), including both adults and children. However, a key limitation persists: the absence of an adjustable ankle joint. This constraint increases socket pressure, reduces terrain adaptability, and limits compatibility with varied footwear. This thesis proposes a modular design framework for an adjustable ankle mechanism that enables users to modify sagittal plane positioning manually. The framework supports integration into Gyromotics’ product portfolio while addressing market strategy, team structure, scalability, lifecycle, and portfolio management. Applied to the Nova foot, it emphasizes user-centred functionality and compliance with MDR and ISO standards. The proposed solution aims to improve the performance and ergonomic accessibility of dynamic feet, enhancing the quality of life for lower-limb amputees. |
