Feeding Device
The Goal: A spoon support system will assist our client with independent feeding. The client has cerebral palsy
and has difficulty with independent feeding due to muscle spasms and fine motor involvement.
The Product: The design consists of : (a) a Steady Spoon from Sammons Preston Rolyan which keeps level
even in the event of tremor or changes in arm position, (b) parallel two-member architecture drafting lamp with
side table clamp, (c) spiral- spring assembly to allow the spoon to spin from scoop to bite orientation, (d) a
velcro spoon attachment.

Feeding Device
The design will dampen spastic movements of the hands and
eliminate spills from the utensil. The client will be able to
scoop food and position the spoon for hands-free biting. The
spoon is removable for washing.

Team: Pho Dac Biet To Go!
Motorized Easel
The Goal: The client is an accomplished artist who has osteogenesis imperfecta, a condition which results in fragile
bones. Range of motion is severely limited. Mode of transportation is a motorized wheelchair. The team endeavored to
produce an easel which will allow the client to independently move a canvas. Prior to this project, the client painted on a
vertical canvas while lying on the floor or table. Any movement of the canvas or easel had to be done by another person.
The Product: A motorized
easel has separate pulley
systems operated by motors
to provide the vertical and
horizontal movement.
Mounting the easel on wheels
provides the front/backwards
motion. The team plans to
place the entire structure on a
track and use another motor
to operate this movement. A
tilting device similar to those
on computer monitors will
accommodate a rotational
movement. Large clips attach
the canvas to the easel can
easily be adjusted for different
canvas sizes.

Team: Krewe BME
Assisted Drawing Device
The Goal: Cerebral palsy severely affects a public school student’s creative ability. The client requires the
assistance of an occupational therapist to participate in daily classroom activities. Her most successful
drawings are produced when her hand is guided by an assistant. The goal is to provide an assisted drawing
device allowing more independence.
The Product: A modified pantograph which enlarges or reduces a primary drawing includes the following
modifications: (a) the image transferred onto the user’s paper is half the size of her hand movements, (b) a
cushy ball fits atop an easy grip handle, (c) a guide (rod below the cushy ball) prevents the user from applying
enough force to break the writing utensil, (d) the fabrication of the wood bars in the pantograph provides a
natural resistance to the user’s hand to prevent jerky movements.

Team: The Solution
Emergency Locating System
The Goal: An emergency locating system will solve the
issue of locating people with physical disabilities during a
disaster.
The Product: Specifications include: a Global
Positioning System receiver, encode, 5-watts radio
transmitter operating at 406.025 MHz, and lithium
battery. The EPIBRS (Emergency Positioning Indicating
Radio Beacon) will be used in the operation of a device
mounted onto the client’s mobility assistive equipment .
The proposed system will allow the clients to call for help
without using cell phones or landline communication.
Emergency preparedness has become a prevalent
issue in the United States because of recent
events involving terrorism and natural disasters.
Hundreds of people lost their lives during Hurricane
Katrina and many are still missing. Many deaths
were secondary to people’s inability to call for help.
If these individuals could have been located, their
lives could have been saved.

Team: The Solution
Emergency Locating System
The team plans to start a
company within the personal
response industry. This company
will act as a Mission control
Center that will filter pertinent
emergency responders. The
clients will maintain service
through a monthly service
charge.

Team: Biowomen
A Chair on Wheels
The Goal: A preK student with amyoplasia
congenita suffers from joint stiffness along
with muscle and nerve degeneration. She
uses a special chair with casters that fit under
preschool tables. The team’s goal is to alter
the device to provide more comfort and
support.
The Product: The alterations to the chair
include: Maximum maneuverability allowed
by caster wheels, an adjustable footrest that is
unobtrusive for the other students in the class,
a head pointer for craft-making and other
class uses, new cushions and upholstery, and
a storage bag to hold markers and the head
pointer. The cushion coverings are easily
removable for washing, and the head pointer
and footrest are both adjustable.

A Chair on Wheels
Because the client requires her chair at school,
the team could not make alterations until after
the design show. A mock up of her chair was
built for the prototype review. All the pieces are
easily removable for easy attachment onto the
actual chair.

Team: Refugee All-star Design
Van Transport System
The Goal: The client has Osteogenesis Imperfecta, a disorder characterized by brittle bones. Due to the nature of the
disease, the client has to ride lying on a pad on the floor of a minivan. The team devised a safe, comfortable and less
restrictive chair as a method of transport.
The Product: The chair is a raised
platform upon which a 4 inch
Tempura-pedic pad rests. The top of
the pad is just above the level of the
van’s window to allow the client
viewing access. Surrounding the
platform is a safety net attached to
the frame and hung from the roof by
steel wire and carabiners. In event
of a collision and/or a rollover, the
net is designed to catch the client
and slow her down as gently as
possible to prevent striking a hard
surface. The platform is constructed
of PVC reinforced by steel wire, and
locked into place using the original
seat base. It is covered with a
removable skirt which can be
interchanged and washed. The pad
has a removable case for similar
purposes.

Team: Pro Bono
Emergency Communication Device
The Goal: This product is a communication device designed for use during
any natural disaster when normal means of communication are down.
The Product: The design is an
Emergency Communication device
(ECD) capable of keychain remote
activation. The system repetitively
sends a voice message receivable
on a standard AM radio. The
synthesized voice has location and
other customizable information
included as needed. The ECD
mounts on a wall, has status
information of the user and a two
mile effective range. The unit will
operate for a fixed period and will
then stop operating without user
action. Rescuers can pick up the
distress signal by using an ordinary
portable or car radio. The ECD is
customized for each user’s needs.
The transmitted message is
preprogrammed with info that will
direct the rescuers. It also prompts
the user for specific action and
remits info regarding the ECD’s
status.
21
Team: Pro Bono
Emergency Communication System
Activating device
In an unactivated (ready) state, the unit awaits input from either the remote control or external buttons on the wallmounted unit. Once activated, the transmission begins and continues at a series of non-repeating intervals. In
order to avoid mistaken activation or continued transmission after rescue, the user is required to acknowledge the
device once every eight hours. Any automatic deactivation is noted clearly by the device both visually and aurally.
This product was designed to be an additional life-line during a natural disaster when normal means of
communication are often down.

Team: BANG'N
Deck and Ramp System
The Goal: A deck and ramp system will enable our client to access to his front yard, back court, and home. His
home is about 30 inches above ground level and has several access points to the ground level, all which require the
use of stairs. His muscular dystrophy condition makes it difficult to access the stairs. He expects of use a
wheelchair at some point.
The Design: Due to
the physical restraints
of the property, the
ramp will be only 30
inches wide, 12
inches less than the
standard 42 inch
ramps in the city. It is
very important to our
client that the space
in the back courtyard
is not compromised.
To accomplish this,
the ramp extends into
the backyard at a
grade of 6:1 rather
than the standard
12:1.

Design features include: (a) slip guards and edging blocks to
prevent falls, ((b) pressure treated lumber lifted off the ground
to prevent water accumulation, (c) semi-modular for ease of
assembly- (the system is tied together with removable
screws), (d) aesthetics and usability—the system opens up
extra space outside the back door, which can be used for
hobbies.

Classroom Ramp
The Goal: The client is a four year old with amyoplasia, a condition which causes joint contractures. She uses a
wheelchair for mobility. The school’s computer lab is a portable building outside of the main school building and is
not wheelchair accessible. Individuals enter and exit by stairs. The team’s goal is to give the client access to the
lab via a ramp system located at a secondary entrance.
The Design: A ramp system
will enable wheelchair access
to a trailer classroom. The
ramp has to reach a height of
31.25 inches, and must have
a 1:12 slope (5 º), as
specified by the Americans
with Disabilities Act. Total
ramp length is 31.25 feet with
a width of 42 inches. The
ramp must not block the
other entrance or the
sidewalk. Therefore, it is
designed with an 180 º turn
attained through the use of a
5 by 8 foot landing. The
design also includes a 5 by 5
foot landing at the entrance
to allow the user to make a
90 º turn into the classroom.
27
Team: Teenage Mutant Ninja Turtles (TMNT)
Classroom Ramp
The ramp includes a
handrail 3 feet tall
supported by posts 4
feet apart. There is
also a 3 inch curb at
the edge to keep the
wheelchair from
straying off the ramp.
Lattice work will be
placed under the
edges of the ramp
and platforms to keep
other children from
crawling under it. The
load capacity must be
at least 50 pounds per
square foot.
