Vivar Intelligent Wheelchair

To improve the physiological decline and psychological distress caused by prolonged sitting in wheelchairs for individuals with lower limb mobility impairments or those undergoing rehabilitation from sports injuries, this "stand/sit" convertible wheelchair is designed. The transition between standing and sitting positions is achieved through an "X"-shaped lifting structure, powered by a gear rack and motor, with hydraulic rods to support the user's hips. Users can switch between modes using physical buttons or control the transition via a smart belt, which detects muscle relaxation. The smart belt also monitor the user's body data in real-time, with the data displayed on a mobile app. The chair's appearance combines a sporty and high-tech aesthetic, breaking away from the conventional wheelchair design and challenging stereotypes of individuals with special needs.
