Inventors Create Wheelchair Innovations for Safety,
Affordability and Mobility
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.
According to Ford, "our automatic wheelchair brakes and wheel
locks help prevent falls, free up staff and improve quality of
life... and that's gotta make a guy feel good."
On the other side of the world in Australia, Nick Morris is also
innovating with an eye toward reducing wheelchair related
injuries. His invention, the Vulcan Wheel, is an ergonomically
designed one-piece extruded aluminum wheelchair wheel for use in
general travel and sport. The unique Vulcan design has
streamlined both the push rim and wheel rim of a conventional
wheelchair wheel and provides the user with increased surface
area to propel the wheelchair.
Morris was injured in a motorcycle accident at age 16 and
credits his involvement in sport as the key to his
rehabilitation. Nick's passion for sport led him to design an
improvement on the conventional wheelchair wheel, in conjunction
with co-inventor David Goding.
Conventional wheelchair wheels have a base construction made up
of wheel rim, a push rim and a number of adjoining pieces
connecting the rims together. In order to apply force to move a
wheelchair, the user grips the push or wheel rim to propel the
wheelchair forward. The wheel rim and push rim are joined
together by five joins around the wheel causing a vast potential
for hands to get caught or jammed in the gaps. This causes
trauma and injury to the hands and fingers, often resulting in
friction burns, dislocation of the fingers, and skin abrasions.
It is also not uncommon for parts of clothing, or objects such
as sticks and debris, to get caught in the gap. Secondly, there
is insufficient room for placing the palms of the hand on the
push rim, as there is not enough surface area between the wheel
rim and push rim.
Morris and Goding's ergonomic design compliments the use of palm
and fingers and reduces the risk of trauma to the hand as there
is no area for fingers, thumbs or external objects to get jammed
in between the two rims.
The new wheel also weighs less due to a decreased number of
components, and is less likely to break down. Its one-piece
structure also provides the push rim with an additional degree
of stability, making it less likely to buckle and flex when
pressure is exerted during pushing, making it ideal for
wheelchair sports.
Elsewhere the needs of those who travel with wheelchairs have
been reviewed with an eye toward innovation. An Augusta Georgia
firm offers a "wheelchair in a bag" that folds and unfolds in
seconds and weighs in at just 17 lbs. The lightweight chair is
made possible due to the use of aircraft aluminum, which
provides the necessary strength with a fraction of the weight of
steel. These compact chairs can be bagged and carried with a
handle or shoulder strap and include features such as flip back
armrests, folding footrests and adjustable wheel locks.
Everything you would expect in a full weight chair.
Don Schoendorfer, Jerry Ford, Nick Morris and David Goding have
made significant contributions through their inventions, which
have improved access, efficiency and safety for wheelchair users
throughout the United State and across the globe. And with the
21st Century still in its infancy there is every reason to
believe there are more wheelchair innovations in store.
