4. THE PROBLEM Clip fatigue Surface Area of the Clip
Withstand chrome plating buildup
Steven
Clip fatigue
-once the clip becomes too fatigued from continuous bending, the parts become loose and fall, resulting in scrap
Surface Area of the Clip
-maximum surface area is needed for the current to flow through the stainless steel clip and plastic part

5. PROJECT GOALS Increase and quantify clip grip strength
Significantly prolong and quantify clip lifetime
Reduce scrap rate
Improve ergonomics
Steven
-lower overall cost by increasing the lifetime of the part and decreasing the scrap rate, even if overall complexity of the clip increases
-current scrap rate
-Stewards of the Environment =)

6. STATUS Designed and in process of constructing fatigue test device
Performed force testing of original clips
Obtained material for clips
In process of creating improved clip prototypes
Steven - Identify the problem with lacks - parts fall off
Research how to solve problem
brainstormed possible ideas such as: reduce stress concentrations, increased grip strength etc
Designed improved clips in CAD - Improved clips with lower stress concentrations and other clip geometry solution
currently at the prototyping stage
We will build many prototypes and make a decision from there
