ENGINEER
DESIGNS WHEELCHAIR COSTING LESS THAN $50
Don's (Don Schoendorfer - FWM President & CEO) approach to this design was to use components that
are manufactured in high volume for other products.
By this method, we enjoy a low piece price cost.
He removed every extra feature possible, ending
up with the least expensive design that will satisfy
a large portion of the world's need for wheelchairs.
This wheelchair design lends itself to manufacture
by highly efficient companies where assembly costs
are relatively low.
A
LAWNCHAIR?
For
a wheelchair you need a chair. He selected the least expensive
chair he could find - a molded plastic patio chair. Perfect!
It's waterproof. It's durable. It's comfortable to sit
in for long periods. It's washable. It's made in many countries.
You can drill holes in the arms and legs so it can be mounted
on the frame.
MOUNTAIN
BIKE WHEELS - A GOOD FIT! A
wheelchair needs wheels. He selected 24 inch bicycle wheels. For
added durability he selected bicycle tires made for mountain bikes.
The difference
between the ones we use and those on millions of bikes made around
the world is a special wheelchair hub. Ours is considerably stronger.
The mountain bike tires allow our chair to transverse rocky, uneven,
and even muddy terrain that would be impossible in a regular wheelchair.
We are frequently asked about using inflatable instead of hard tires.
Inflatable tires allow movement over terrain that would be impossible
with a hard tire. There is almost no place on earth where the tools
to repair a flat tire aren't available.
HUNT
FOR FRONT WHEELS SUCCESSFUL
You need castors for the front legs. Don found 8 inch diameter
castors that are inexpensive but rugged enough for this wheelchair.
GONZO
HELPS
PUT IT ALL TOGETHER
For
a wheelchair you need a frame. We started with steel conduit because
he could bend it himself. Once we got something close, Don took
it to a steel fabrication company in Los Angeles called Mark IV Metal
Products. (www.markivmetal.com).
There Gonzo Viana used his creativity and his years of
experience to turn his crude design into something that could be mass-produced.
The bends in the single piece frame follow the contours of the molded
plastic chair. At the same time, the frame is something that can be made
relatively inexpensively.
VOILA!
These parts, plus a simple footrest, a few dozen
nuts and bolts and miscellaneous pieces is all that it takes to make
one wheelchair.
Another benefit from this design is standardization. There are relatively
few parts, so there is little to stock for repair.
CHAIR AND SHIPPING TO DEVELOPING COUNTRY UNDER $50
The
plan was to ship the wheelchair in a kit - for two reasons. One reason
is that they take up less space that way. We can pack 550
kits in a standard 40 foot container. The second reason is that in
most countries the labor to assemble a kit will be very low. With little
training,
someone who is good with his or her hands can make three wheelchairs
in one hour.
ASSEMBLY IS DONE ONSITE AFTER DELIVERY
Don made assembly instructions with photographs so someone
who cannot read English can learn to assemble these kits. We supply an
assembly tool kit (5 simple wrenches and one air pump) with every 20
wheelchair kits.
We verified that volunteers in developing countries can
easily manage wheelchair assembly. We shipped 43 wheelchairs in kit form
to Luanda, Angola. Our assembly team consisted of 16 young Angolan volunteers
using simple hand tools.

New Wheelchair Design
After seeing thousands of chairs in action,
Don has made some revisions to the original chair.
The changes seen
above were made in 2004.
Below is a picture
of
the
wheelchair being tested.

Assembling in Iraq (above)
2004
was such a year of celebration for Free Wheelchair Mission.
One of the main reasons was because we found a new wheelchair supplier
and they've made upgrades to the wheelchair. It is more effective and comfortable
for a larger number of users.
Among the improved design features are side panels placed alongside the
seat of the wheelchair, giving more protection from anything thrown up
from the ground by the movement of the chair. The wheel has been fitted
with a hand-rim to make the propelling of the chair easier and cleaner;
the footrest has been repositioned for easier entry into the chair and
more comfort while in the chair, the brakes are better, and the axle is
larger, creating more strength and durability and propulsion once the chair
is set in motion. The wheelchair is still relatively lightweight and is
now more rugged and suitable to the locations where it's being utilized.
The most exciting part about these new
features is that they do not cost more and we can still deliver a
chair for under $50. It will ALSO include
a bicycle tire pump and a couple of tire patches . Isn't it astounding
that God would lead us to a new manufacturer with an innovative approach
to our design needs? |
