The Team

Goals

▪ Finalize Requirements ▪ Verify problem statement ▪ Finalize Design Scope

Problem Statement:

For people confined to wheelchairs, using public restroom facilities can be an extremely difficult and unpleasant experience, heightened if they have limited to no upper or lower mobility. As a result of this struggle, a trip to the restroom can take as long as an hour, leading users to avoid using public restrooms all together. Two of the main concerns are transferring from the wheelchair to the toilet and back, and the self cleanup process. The goal of this project is to design a device that will assist users in the transfer and cleanup process of using public handicapped restrooms to enhance their comfort and quality of life.

Stakeholders

1. Customer: Art North 2. People confined to wheelchairs 3. Caretakers 4. Donald Pophal 5. Doug Jaehn 6. Chris Hilderbrant 7. P19011 MSD Team 8. MSD Office

Scope

• 1. Little to no lower

mobility

• 2. Some upper body

strength

• 3. Low dexterity in

hands

• 4. Fits in ADA compliant

public restrooms

Constraints

• Budget: $500
• Easily installed in handicapped restrooms
• Resources for power available (i.e. certain level of

water pressure, electrical)

• Compliant with restrooms following ADA restrictions

and requirements.

• Adjustable for various models of toilets

Users in Mind No Lower Body Movement ▪ Wheelchair users, full upper body use ▪ Wheelchair users, moderate upper body use ▪ Users with caretakers Limited Lower Body Movement ▪ Wheelchair users, can stand/walk ▪ Motorized scooter users ▪ Walker users ▪ Leg brace users ▪ Crutches users

Use Case Scenario I

User enters the restroom

User transfers from chair to toilet

User removes necessary garments User cleans themselves

User transfers from toilet to chair

User replaces necessary garments

Wheelchair user, ADA restroom; moderate upper body strength no lower body use

• have to

lift/lower self

• nto toilet
• use toilet seat
• use grab bars
• cannot reach

under self

• cannot clean

any accidents

• have to

lift/lower self

• ff of toilet
• use toilet seat
• use grab bars

Use Case Scenario II

User enters the restroom

User transfers from chair to lifting seat

User removes necessary garments User cleans themselves

User transfers from toilet to lifting seat

User replaces necessary garments

Wheelchair user, W.A.R. 3 in restroom; moderate upper body strength no lower body use

• adjust height of

lifting seat

• lift handle
• use handles to

transfer

• replace handle
• lower seat
• lift seat as needed
• clean self
• adjust height of

seat

• lift handle
• use handles to

transfer to chair

• finish

Current State, Future State and the Gap

Current State:

• Hydraulic Lifts
• 8 in. height differential
• Liftable Arm Rests
• 420 in2 footprint
• Max load 405 lbs
• 155 lb for descent

Future State:

• Adjustable Height
• Secure supports
• Increased

Accessibility

• Minimal weight

required to descend
