The prolonged by using a wheelchair is a reality for upwards of 100 million people across the globe due to disabilities brought about by illness, accident or advanced age. One of the challenges faced at this large and diverse group are; insufficient access to adequate wheelchairs due to poverty, the chance of serious and in many cases life threatening injury due to wheelchair roll-away or wheel pinning, and impediments to visit caused by the cumbersome nature of normal wheelchairs.
Fortunately, you can find innovators in the office who have in recent years addressed these issues through some truly amazing wheelchair inventions.
Don Schoendorfer, a mechanical engineer from Orange County, California, was conscious that many of the poorest people world wide live on lower than $2 a day, and that when they were needed, standard wheelchairs were financially not even considered at several $ 100 per unit. Schoendorfer experienced a goal; to build the world’s cheapest wheelchair with the benefit of the indegent with disabilities.
Tinkering for three hours every morning in his garage workshop, Schoendorfer struggled to generate a design for just a wheelchair that might measure up to harsh terrains and climates at the 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 priced item as being the centerpiece of his design, equipping his inexpensive chair with two sturdy bike tires as well as a custom designed chassis.
The actual result? A durable, low cost wheelchair that can be shipped anywhere in the world for under 50 dollars. Schoendorfer’s nonprofit group, Free Wheelchair Mission, has delivered a lot more than 75,000 to individuals in Angola, India, Peru, and Iraq. His mission? In accordance with Schoendorfer, “I have a small goal. Twenty million chairs distributed free by 2010.”
In Minnesota, farmer turned inventor - Jerry Ford, was approached by his son Zack who worked in the nursing home together with noticed your schedule of elderly residents forgetting to put the brakes for their manual wheelchairs before attempting to stand. The end result was usually a bad fall as being the wheelchair would roll-away from the resident while they applied weight for the chair’s arms when attempting to rise. Problems encountered by elders in other areas as well, especially amongst those who suffer from senility, Alzheimer’s or just forgetfulness.
U.S. Congressman Gil Gutknecht of Minnesota has drawn awareness of the problem, mentioning that a fall with this kind is “dangerous for the elderly, specifically those in assisted living facilities, who are often fragile. Only one fall can be quite a painful death sentence.”
Ford set to work almost immediately along with just a few hours, and with just $19 in spare parts, turned a mental picture of your new wheelchair automatic foot brake into a reality. Ford’s invention is a revolutionary wheelchair safety system that allows the wheelchair to relocate when a patient is onboard, but which auto-sets a brake right after the user rises. The system does not compromise patient comfort or safety by causing pressure points and allows the wheelchair to control normally including normal folding.
In line with Ford, “our automatic wheelchair brakes and wheel locks aid the prevention of falls, regain staff and improve quality of life¦ and that’s gotta produce a guy feel happy.”
On the other side worldwide in Australia, Nick Morris is also innovating by having an eye toward reducing wheelchair related injuries. His invention, the Vulcan Wheel, is undoubtedly an ergonomically designed one-piece extruded aluminum wheelchair wheel to be used in general travel and sport. The initial Vulcan design has streamlined both push rim and wheel rim of a conventional wheelchair wheel and gives the user with additional surface area to propel the wheelchair.
Morris was injured in the motorcycle accident at 16 and credits his involvement in sport since the key to his rehabilitation. Nick’s adoration for sport led him to design an improvement about the conventional wheelchair wheel, jointly with co-inventor David Goding.
Conventional wheelchair wheels have a base construction derived from wheel rim, a push rim as well as a number of adjoining pieces connecting the edges together. So that you can apply force to move a wheelchair, the person grips the push or wheel rim to propel the wheelchair forward. The wheel rim and push rim are gathered by five joins throughout the wheel causing a vast likelihood of hands to have caught or jammed inside the gaps. This makes trauma and destruction of the fingers and hands, often leading to friction burns, dislocation in the fingers, and skin abrasions. It is additionally not uncommon for regions of clothing, or objects for instance sticks and debris, for getting caught from the gap. Secondly, there’s insufficient room for placing the palms in the hand around the push rim, since there is not enough surface between the wheel rim and push rim.
Morris and Goding’s ergonomic design compliments using palm and fingers and reduces the risk of trauma for the hand because there is no area for fingers, thumbs or external objects to acquire jammed between the two rims.
The new wheel also weighs less because of a decreased amount of components, which is less likely to collapse. Its one-piece structure also supplies the push rim having an additional amount of stability, which makes it less likely to buckle and flex when pressure is exerted during pushing, which makes it ideal for wheelchair sports.
Elsewhere the requirements of those who travel with wheelchairs have already been reviewed through an eye toward innovation. An Augusta Georgia firm comes with a “wheelchair in a bag” that folds and unfolds in seconds and weighs about just 17 lbs. The lightweight chair is done possible due to use of aircraft aluminum, that gives the necessary strength that has a fraction in the weight of steel. These compact chairs might be bagged and carried using a handle or shoulder strap and include features including flip back armrests, folding footrests and adjustable wheel locks. All you could would expect inside a full weight chair.
Don Schoendorfer, Jerry Ford, Nick Morris and David Goding make significant contributions through their inventions, that have improved access, efficiency and safety for wheelchair users through the entire United State and around the world. And with the Twenty-first century still in their infancy there’s every reason to think there are more wheelchair innovations waiting for you.
