Team Akira
•
Client Description: A seven year old boy
with cerebral palsy needs a mobility device.
He requires constant adult supervision on
the playground because his current walker
gets lodged in the sand.
•
Objective: An all-terrain walker to facilitate
his independence and interaction with his
peers.
•
Design: The outdoor walker features large
wheels for better traction, partial open face
design for interaction with peers, a wide
base for stability, and fixed rear wheels for
better maneuverability.

Bad News Bears
•
Client Description: An autistic 13-year old
is an active youth who would benefit from
riding a bicycle independently. However,
safety concerns prevent him from riding a
regular bike.
•
Objective: A bicycle designed to prevent
falls or loss of control.
•
Design: The team added functional
modifications for overall safety and usability
on the three-wheel vehicle, Miami Sun
“Traditional Trike”. Features include a
supportive seat, safety harness, chain
guard, pedal guides, auxiliary brake control,
handle bar adjustment soothing handlebar
vibrations, and a basket.

Team Blue
•
Client Description: Home health agency
dealing with patients who must use oxygen
at all time and use walkers and/or
wheelchairs. The patient is attached to an
stationary oxygen concentrator having up to
50 feet of plastic tubing to increase travel
distance within the home.
•
Objective: constructing a device that will
allow ease of movement preventing the
client from getting tangled in and tripping
over the oxygen tubing.
•
Design: The Reel Solution. A patented
device was purchased and modified.
Modifications include: substituting circular
lumen tubing for star lumen tubing, and
mounting the device onto a 5 foot pole with
a weighted base to elevate the tubing from
the floor. The spring loaded reel
automatically retracts with one pull. A velcro
bracelet attached to the wrist puts tension
on the arm rather than the nasal canula.

The Dream Team
•
•
•
Client Description: A professional who
suffers from post-polio syndrome relies on
an electric wheelchair for mobility. She
cannot walk or use both arms properly, and
uses a respiratory device.
Objective: (1) an adapted desk to maintain
proper arm position and to prevent pencils
from rolling off. (2) a device that keeps the
ventilator hose out of the way, but available
for immediate use. (3) an effective wireless
phone system.
Design: (1) Rubber grips added to her desk
act both as pencil holders and handles to
manipulate with her hands. (2) A docking
device snaps over the end of the ventilator
hose allowing for easy access and storage.
(3) A Plantronics CS50 Wireless Office
Headset System allows her to call anywhere
in the office.

GANG GREENwave
•
Client Description: A professional woman
with paraplegia uses a wheelchair for
mobility, and drives to several work sites
daily. Arthritis causes pain in her hands
preventing a manual transfer from her chair
to the driver’s seat.
•
Objective: A device which the client will sit
on will allow independent transfers to and
from the van.
•
Design: An inflatable cushion connected to
a pump will lift her to an elevation equal to
that of the driver’s seat. A frame design will
provide stability. As the cushion inflates, the
frame expands, providing a level seating
area and keeping a balanced center of
mass. The frame will attach to a fixed point
on the van to provide additional support.

Greenwave Design
•
Client Description: A 5 year old nursery
school student with microcephaly who needs
an adapted device to independently use the
same bathroom as her peers.
•
Objective: Building a device which allows
the child to use the same restroom as her
peers.
•
Design: A nursery step stool has equally
spaced steps of appropriate height, a large
platform area having adequate strength and
weight to prevent tipping, a handrail for
balance, a non-slip surface, anti-skid
bottom, and a waterproof sealant.

Innominate
•
Client Description: Patients with head
injuries become agitated and lose control of
their motor functions causing lateral chair tip
overs.
•
Objective: a device added to an existing
wheelchair that will prevent tip overs.
•
Design: An anti-tipping device for
wheelchairs was designed. Heavy weights
are attached below the seat between the
wheels to lower the center of gravity. It can
be attached to all wheelchairs and can be
permanent if desired.

MGM Grand
•
Client Description: This child has spinal
bifida and Arnold Chiari II malformation of
the brain stem. He is paralyzed from the
waist down. He is severely allergic to latex,
is tube fed, has a shunt, and uses a
wheelchair.
•
Objective: Building a device which allows
the caregiver to more easily transfer the
child from the wheelchair to a low bath chair
in the tub, and vise versa.
•
Design: A bath chair attached to a high
base raises it to the height of the
wheelchair. This will reduce the strain on
the caregiver while in the transfer process.
The design is light in weight and water and
rust resistant. It provides support while in
the tub.

Grease Monkeys
•
Client Description: A 5 year old girl with
cerebral palsy has spastic quadriplegia
causing loss of lower body control and
decreased upper body control. She has
difficulty maintaining an upright position.
•
Objective: A device allowing her to sit on
the floor and play with her own peers.
•
•
Design: the supportive floor sitter will allow
her to support herself and interact with
children of her own age. It features fine
copper tubing, cherry mahogany finish on
the pine removable tray, rounded edges to
prevent injuries, lower back support, a tip
proof design, and a special seat cushion for
maximum comfort,

Stuck in an Elevator
•
Client Description: A 3 year old boy with
cerebral palsy has only partial control of his
legs and cannot walk unassisted.
•
Objective: An design which allows him to
stand erect and play outside.
•
Design: A system suspends the client from
above and tethered to a track. He is free to
move along the track. Three major parts in
the design are: (1) a frame to support the
weight of the client and all other parts, (2) a
track that can attach to the frame and
provide horizontal motion, (3) a harness to
hold the client comfortably and allows ample
range of motion with his arms and legs.

Yam Wars
•
Client Description: An 11-year old with
Rett syndrome enjoys riding a tricycle.
However, due to a large growth spurt, she
can no longer fit on a standard child-size
tricycle.
•
Objective: A safe, functional, adjustable,
portable, and entertaining bicycle that the
client can operate under the supervision of
an adult.
•
Design: A commercially available bicycle
was purchased and adapted with (1) rear
wheel stabilizers to compensate for poor
balance, (2) velcro attachments to bind the
client’s feet to the pedals, (3) a seat back
with an attached lap belt to provide torso
support.

Wheel of Fortune
•
Client Description: A 10 year old boy who
uses a wheelchair for mobility enjoys
frequent trips to the beach.
•
Objective: A design which allows easy
movement on sand and beach terrain.
•
Design: A beach adapted tricycle will allow
for easy movement on sand and beach
terrain. Using bike parts and special wheels
for beach travel, a specialized tricycle with a
hand crank, special seat, padded leg
holders, and harness was created. Special
considerations were taken to allow minimal
operating forces by the user to prevent
fatigue and correct crank and seat
positioning. The seat was designed to
maximize comfort for the client’s back.
