Competition sponsored by PTC® (www.ptc.com), COMSOL (www.comsol.com), and Tech Briefs Media (www.techbriefsmedia.com) attracts nearly 1,000 innovative product ideas from engineers and students in 51 countries.
New York, NY – A new invention could help millions of manual wheelchair users increase their mobility while decreasing upper body, repetitive stress injuries. Many who suffer from muscle pain, torn rotator cuffs, joint degeneration, and carpal tunnel syndrome due to muscle overuse will benefit from the Rowheel Wheelchair Propulsion System. This innovative design uses a pulling/rowing motion as opposed to the standard pushing motion.
Developed by Salim Nasser of Merritt Island, FL, the Rowheel System design involves adapting a planetary gear system at the center of the wheel, which reverses the pulling motion of the user into a forward motion of the chair. The unique change from pushing to pulling along with the mechanical advantage created by the use of the gear system provides an overall increase in user endurance and range.
