3D-Printed Wheelchair Light Enhances Visibility and Communication

A team of student engineers and designers at the University of Illinois Urbana-Champaign, collaborating with the (dis)Ability Design Studio, has developed 'Sol,' a novel mountable light designed for wheelchairs and other mobility devices. The project was initiated by graduate student Carter Schott, who has muscular dystrophy and sought to improve his own daily activities, recognizing the broader applicability of such innovations for others with disabilities.

Sol is conceived as a solution to enhance the visibility of wheelchair users, particularly in hazardous environments like parking garages where they are often below a driver's line of sight. Additionally, it functions as a signaling device in academic settings, allowing users to attract attention, similar to raising a hand, to ask questions during lectures. Schott's design process involved sketching, computer modeling, and the creation of 3D-printed prototypes, with him personally designing all components, including the attachment mechanisms, circuitry, and light fixture.

The project expanded with the involvement of the (dis)Ability Design Studio, bringing in four industrial design students and one graphic design student. This collaborative approach emphasizes user-focused design, with the studio's founder, Deana McDonagh, stressing the importance of technologies being designed by, as well as for, their intended users. Sol features a USB-powered LED that shines through a frosted acrylic loop, diffusing the light for visibility without being distracting. A switch, mountable on the wheelchair's arm, controls the light's functions, offering modes such as always-on and flashing.

Schott is currently developing Sol using a 3D printer in his dorm room. The team is actively seeking user feedback through a global survey, aiming to refine the design for universal application across various mobility devices like scooters and walkers. The demand for Sol is evident, with over 400 survey responses received in the first week. Schott plans to offer the lights for free on the Illinois campus and sell them through his company, Innovative Independence, prioritizing affordability and accessibility over the often-expensive and insurance-navigating assistive technology market.
