                                                                                 2
Team Design                               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.




                                                                                                                  3
Team Design                                  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.                                 Product demonstration

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.

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.

                          Demonstration


   The device is designed to be a functional, child-friendly, and aesthetically pleasing product. The
   client is very creative and needs a way to express her ideas on paper.

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.

                                                          The team plans to start a
                                                          company within the personal
                                                          response industry. This company
                                                          will act as a Mission control

                                                          emergency responders. The
                                                          clients will maintain service

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.

Team: Biowomen                          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.

         Activating device

In an unactivated (ready) state, the unit awaits input from either the remote control or external buttons on the wall-
mounted 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.

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 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.
