Easel 5000 New Adjustable Easel

Introduction  Senior Design Team 3  Team Easel 5000  Alison Biercevicz  Seth Novoson  Justin Yu  Cooperative effort between UConn’s Biomedical Engineering Senior Design and the National Science Foundation

Who the Project will Benefit  National Science Foundation  Engineering Projects to Aid Persons with Disabilities  Mission- To assist individuals in reaching their maximum potential for enjoyable and productive lives  Clients  Dr. Brooke Hallowell  Tom Depugh

What is the Project?  An adjustable art easel for an artist with cerebral palsy

Cerebral Palsy  Cerebral palsy is a condition resulting from brain damage  The symptoms  Loss of fine motor ability  Abnormal muscle tone  Abnormal movements  Vision problems

Why the Project is Being Done  The easel created in 2003 did not completely meet the needs of the artist, Tom Depugh  Previous design  Complicated motor  Not completely adjustable  Tripping hazard  Was not portable  The canvas did not project  No light source

2003 Design Legs created a tripping hazard The canvas didn’t fully project toward the artist Too large to be portable Motor was too complicated

Project Objectives  Expected Results  An easel designed and constructed to completely meet the needs of Tom Depugh  A design that addresses the problems with the previous design

Team Objectives  Use educational background to create an effective design  Develop design process  Learn  Project Planning  Management  Troubleshooting

Methodology
