Abstract: This paper introduces a new concept of manual wheelchair (MWC), consisting in different modules enabling customizations based on specific pathologies as well as patients’ environment. This wheelchair is as maneuverable as an electric wheelchair while remaining lighter, more convenient and less costly. The module concept allows adaptability aimed at specific uses making it particularly suitable for the elderly. The first modules proposed in our study concern the standing and folding systems. A new unpublished propulsion system, was also designed to facilitate movement by reducing the physical effort required. These functional aspects are supported by numerical simulations of the structure on the one hand and of the patient’s muscular activity required for wheelchair motion on the other hand. In relation with industry the next step of our study is to propose a rapid prototyping for a better optimization.
