Project Title: Dental Handpiece Redesign
Project Team: Elizabeth Shelley, Brian McGrath, Dave Golebiewski, Gary Stump
Executive Summary: Dentsply Preventive Care is manufacturing a new scalar
(device for cleaning teeth) as shown. They need a new handpiece cover that will
meet customer requirements. The project goal is to develop two different
prototypes that appear and feel like the final manufactured product. Two magnetic
coupling designs and three exterior handpiece covers were developed. A total of
five prototypes were created in a SLA rapid prototyping machine. These prototypes
satisfied the hygienist's need for balance, weight, size, comfort, and cable drag.
Also, the handpiece designs allow the user to easily slide the magnetic coupling
to interchange different front pieces of the scalar. The major areas of study
included ergonomic analysis, materials research, design development, design
analysis, CAD drawings, and rapid prototyping.
