Weed Whipper Redesign

Redesign by:
Michael Enochs Winter 2005 |
The Trimmer/Edger is a common lawn and garden tool used for weed-whipping and trimming grass along sidewalks, paths, or driveways. The design team was able to reduce the entire body into two injection molded pieces that can snap fit together. This will greatly lower the cost to manufacture each unit, which will in turn reduce the price for the consumer. A compliant member was designed to release the cutting twine, this will make the twine dispenser much more reliable when compared to the original design. A material change to PVC, which meets the mechanical properties of the current material but does so with a lower density and a lower cost, will satisfies two major customer requirements, cost and weight. This material also allows for a translucent shield, allowing the user to see what he or she is cutting. This redesign was developed by Michael Enochs, Joshua Martin, Adam Maurer, and Jonathan Neff in Winter 2005, instructors: Prof. Sridhar Kota, Mentor Dr. Donald Malen, and Teaching Assistant Audrey Plinta.
