GFD: Glasses Floatation Device Design Proposal
Introduction:
The GFD is a floatation device for glasses. It's a glasses strap but has a part that will have polyethylene foam inside wrapped in flexible rubber. The device would be used by anyone who goes fishing or is often out on a boat.
Objectives:
The objective of the device is to be an item that anyone can put on and use to prevent losing a pair of glasses. The glasses would use rubber and polyethylene foam. The rubber would be used to attach the strap to the glasses and to case the polyethylene foam. A Dyneema rope would be used as the main strap part.
Design Strategy:
The attachment will be the main focus when starting construction. When the attachment is made it will be tweaked depending on how it performs and if it works. Then floatation will be attached to the Dyneema rope.
Plan of Action:
Research any additional materials. Gain the materials needed to make the prototypes and begin construction. Do a test then based on data redesign, test, and redesign. Then have a final test to verify the redesigns worked.
Testing Procedures:
The device will be tested on floatation and security to the glasses' arm. The first test will be on how secure the device is to the glasses. Then the second test will be the floatation of the device with and without the glasses attached.
Tolerance Analysis:
The attachment and floatation piece would be the priority for durability. The attachment piece has to be the main focus since it would be moved around and held onto the glasses.
Cost/Schedule:
Neoprene rubber is 8.79, Rubber adhesive is 9.99. Polyethylene foam is 14.99, and the 2mm Dyneema rope is 9.99. Total for materials:$43.76. Scissors and a utility knife would cost 14.96.
Starting construction on 10/9. 10/9-10/11 measuring and cutting materials. 10/11-10/13 Building the device with the materials. 10/16-10/17 testing the device. 10/18-10/19 redesigning. 10/23-10/24 testing. 10/15-10/27 redesigning. 10/30-11/1 Final testing and redesigns.
