Pneumatic Lumbar Support Cushion

Team members:

Tony Nelson (Group Leader)
Mike Swift (Communications)
Sara Alford (BWIG)
Dan Hartman (BSAC)
Heather Shaner
Yim Chan (Cindy)

Client:

Julie Sherry, MS, PT
4176 Medical Sciences Center
(608) 265-9601

Reporting period:

December 8 - December 15

Problem statement:

To design a pneumatic lumbar support cushion that undergoes continuous passive motion for a duration of time when a patient is in a sitting position such as driving an automobile.

Restatement of team goals:

Find motor to use in the prototype
Begin construction of prototype
Begin formulating final paper and poster
Update PDS for final paper and poster

Accomplishments:

Decided to use lever for prototype rather than a motor
Finished construction of the lumbar roller prototype
Began working on final paper, poster, and presentation
Updated PDS for final report

Goals for next reporting period:

Finish final paper
Finish poster and presentation
Present prototype and poster in class on Friday
Meet with professor Gruben to discuss final paper and presentation

Project schedule:

Week 1: Met with Client
Week 2: Background Research
Week 3. Research, Brainstorm, PDS completion
Week 4: Finalize 4 main designs and start researching the equipment
needed for these projects
Week 5: Complete draft of Mid-Semester report (start on speech)
Week 6: Give presentations and turn in reports
Week 7: Combine with large group and begin selection of final design
Week 8: Choose final design and split into smaller groups to work on different aspects of
the design
Week 9: Present final design options to client to determine final design and begin
working on finding materials for prototype.
Week 10: Chose final design with the aid of the client, split into small groups to begin details of the final design, research details of the final design
Week 11: Met in small groups (since class was cancelled), researched individually for prototype design, decided what needed to be done for class on friday
Week 12: Worked in small groups on individual aspects of the prototype, continued research for prototype construction, made plans for beginning construction of prototype
Week 13: Constructed prototype for the lumbar roller, began working on final paper, poster, and presentation

Difficulties thus far:

Finding time to meet to work on the final report, poster, and presentation with everyone's busy schedules.

Activities:

Meeting with group in class: ~1.0 hr
Individual work on paper/poster/presentation: ~ 2 hrs
Small group meetings: ~1.5 hrs
Tony, Mike, Dan, and Yim building prototype: ~5.0 hrs
Tony consolidating/making corrections to the final paper: ~2.0 hrs
