This project was to develop an innovative wheelchair design that addresses prevalent issues encountered by users, including back discomfort, inadequate weather protection, and dissatisfaction with conventional propulsion methods. The goal was to introduce a versatile, everyday-use wheelchair into the US market at a competitive price point of approximately $3000. The design approach emphasized ease of use and multifunctionality, leveraging user feedback and extensive market research. The Air Cruiser wheelchair is equipped with subsystems that significantly improve user experience. Its frame, made from lightweight aluminum tubing, ensures durability while keeping the wheelchair light. The weather protection subsystem features a manually operated crank and worm gear mechanism that swiftly deploys an umbrella, enabling users to comfortably navigate various weather conditions. The propulsion and braking subsystems are designed with a ratcheting mechanism that allows for effortless forward and backward movement and includes a twist handle to change direction of movement. Each wheel is fitted with an independent mechanical disc brake system procured from reputable manufacturers. Additionally, the seat and storage subsystems provide lumbar support for added comfort and includes integrated compartments for convenience. These subsystems were developed by specialized sub-teams within Trek Engineered, focusing on frame design, propulsion and braking, seating comfort, and weather protection. Through collaborative efforts and iterative design processes, the Air Cruiser wheelchair successfully meets its objectives of functionality, improved aesthetics, and increased user satisfaction.
