Introduction
The client, Ms. Jill Caruso, currently uses a collapsible wheelchair. She plans to convert to a “rigid” chair in the near future for improved comfort and durability. She is able to get into the drivers seat from the wheelchair and seeks a device which will then take the empty chair and place it into the back of the van through the drivers side rear sliding door.

Problem Statement Sliding door opening is roughly 28” wide Wheelchair is roughly 35”x 26” (footprint) Chair is initially parallel to the van but must be rotated
perpendicular to fit through the door With less than 1 inch of clearance on both sides of the chair, the
device must be very consistent and accurate

Client Preferences
No traditional platform lifts Keep it simple - Client is willing and able to
“help” the chair into the van however possible Do not decrease resale value of the vehicle by
making too many permanent changes Would like to be able to easily transplant the
device to a new van in the future

Design #1
Platform lift design Wheelchair would need to rotate 90° while on
the platform Controlled remotely from the front seat
01/27/07 Ryan Keeler 6
Design #1
Simple to use for operator
Minimal effort required
Potential for wheelchair to fall off
Device requires an inordinate amount of space
Difficult to install in another vehicle
01/27/07 Ryan Keeler 7
Design #2
Side bar lift design Bar hinges to rotate
chair Attaches to arm or
wheel to lift
01/27/07 Ryan Keeler 8
Design #2
Less invasive than full platform lift
Relative ease of use
Limits front seat mobility
Exerts large amount of strain on wheel spokes and arm bars.
Difficult to re-install in new vehicle

Design #3
Under-seat lift design Flat bar under
wheelchair seat lifts chair into vehicle
Front and rear bars keep wheelchair in place on bar
01/27/07 Chad Wainscott 10
Design #3
Easy to use for operator
Least intrusive of all lift designs
Easiest lift design to remove and put in another van
Chance of chair moving sideways on bar
Difficult to load chair properly on lift
Design does not allow necessary preciseness required for placement in van

Design #4
Winch Assisted Lift Pulls wheelchair into
van using electric winch
Chair rolls into place along guided tracks
01/27/07 Chad Wainscott 12
Design #4
Easy to remove and place in new vehicle
Minimal space required Guided tracks allow for
repeated and precise chair placement in allowed space
Requires most setup by operator
Difficult attachment process
