The prolonged use of a wheelchair is a reality for over 100 million people across the globe due to disabilities brought about by illness, accident or advanced age. Among the challenges faced by this large and diverse group are; lack of access to adequate wheelchairs due to poverty, the risk of serious and even life threatening injury due to wheelchair roll-away or wheel pinning, and impediments to travel caused by the cumbersome nature of standard wheelchairs.

Fortunately, there are innovators at work who have in recent years addressed these issues through some truly amazing wheelchair inventions.

Don Schoendorfer, a mechanical engineer from Orange County, California, was aware that many of the poorest people around the world live on less than $2 a day, and that when they were needed, standard wheelchairs were financially out of reach at several hundred dollars per unit. Schoendorfer had a goal; to create the world's cheapest wheelchair for the benefit of poor people with disabilities.

Tinkering for three hours every morning in his garage workshop, Schoendorfer struggled to create a design for a wheelchair that would measure up to harsh terrains and climates at a fraction of the cost of standard wheelchairs. Finally inspiration came in the form of the ubiquitous white plastic lawn chair. The inventor used this low cost item as the centerpiece of his design, equipping his inexpensive chair with two sturdy bike tires and a custom designed chassis.

The result? A durable, low cost wheelchair that can be shipped anywhere in the world for under fifty dollars. Schoendorfer's nonprofit group, Free Wheelchair Mission, has delivered more than 75,000 to people in Angola, India, Peru, and Iraq. His mission? According to Schoendorfer, "I have a small goal. Twenty million chairs given away free by 2010."

In Minnesota, farmer turned inventor - Jerry Ford, was approached by his son Zack who worked in a nursing home and had noticed the dangers of elderly residents forgetting to set the brakes on their manual wheelchairs before attempting to stand. The result was often a bad fall as the wheelchair would roll-away from the resident as they applied weight to the chair’s arms when attempting to rise. A problem encountered by elders in other areas as well, especially among those who suffer from senility, Alzheimer's disease or just forgetfulness.

U.S. Congressman Gil Gutknecht of Minnesota has drawn attention to the problem, pointing out that a fall of this kind is “dangerous for the elderly, especially those in nursing homes, who are often fragile. Just one fall can be a painful death sentence."

Ford set to work almost immediately and in just a few hours, and with just $19 worth of spare parts, turned a mental picture of a new wheelchair automatic braking system into a reality. Ford’s invention is a revolutionary wheelchair safety system that allows the wheelchair to move when a patient is onboard, but which auto-sets a brake as soon as the user rises. The system does not compromise patient comfort or safety by causing pressure points and allows the wheelchair to operate normally including normal folding.
