This document discusses the development of a universal clamping device to reliably attach a cord flexor to different fixtures. It considers using a C-clamp, band clamp, or strap wrench as the basis for the design. The document decides a strap wrench would work best if modified to have a way to attach to fixtures, rotate 90 degrees, and keep the strap tightened while allowing the cord to rotate.

1. Cord FlexorBrian JesticeSean Huerta-Ramos

2. ProblemCurrent method of attaching a device to a cord flexor is not reliableWe had to make a universal clamping device Clamp to current fixtureClamp to be portableClamp to be universalMust allow cord to rotate

3. Beginning IdeasC ClampBand ClampStrap Wrench

4. C ClampHas a crank to adjust the size of handleDoesn’t encompass the entire handle

5. Band ClampA good way to encompass entire handleHowever range of size for each clamp is small

6. Strap WrenchAllows a wide range of handle sizeHandle will have o be modified to fit on the fixture

8. Modifications for the Strap WrenchMost of the handle is chopped of to fit on the existing fixtureA way to attach to existing fixtureA way to rotate wrench 90°A way of keeping strap tightened
