3. Project Background Client Details Work Completed By Others
8 year old male, only child
Physical disabilities in upper extremities
Client currently has a personal assistant
Cannot use the restroom by himself
Is able to pull down his pants
Work Completed By Others
ES 140 students at Vanderbilt
Private assistive technology companies
No one has come up with a feasible solution to the client’s personal needs.

4. Project Definition/Overview
Goals
The client and his family have expressed the need for a wiping device, which will be completed by April 2007.
We plan to continue our iterative process of building prototypes and improving them based on client feedback.
Desired Characteristics
Easy install
Sanitation
Compact and portable

5. Current Status Prototype A constructed December 2006
Presented to prosthetist and advisor
Visited client’s house to ascertain personal needs
Prototype B tested January 2007
Hands-on testing by client
Usable but still crude

6. Prototype A

7. Prototype Iteration Problems with Prototype A Mounting location
Unnatural motion
Potentially high device failure rate
Unrealistic materials
Has to be preloaded

8. Prototype B

9. Prototype B

10. Prototype Iteration Solution solved by Prototype B
Mounted on toilet vs. wall
Front to back wiping
Highly stable
More comfortable and realistic materials
Self-loaded
The client has tested Prototype B and is able to install and uninstall the device on his toilet. He is optimistic about the design and excited about the autonomy it will provide.

11. Current Work Prototype C Progress Client interaction
Optimal position for client usage
Custom molded plaster alginate for perfect fit
Decision on final materials/hybrid of materials
Possible hinge design
Client interaction
House call to make toilet mold
Phone and communication with advisor
Dunc Face

12. Future Plans Prototype C Learn CAD Safety features Client usage
Applicable on all toilets
Placement of wipes (Swiffer design)
Learn CAD
Send to get machined ($300)
