The client asked for a design with no screws, so clips are chosen. However, the clip hook was broken during drop testing, what should we do?

---An engineer
 

1. Commonly used clip shapes




 
2. Factors to be considered before clips are designed
 
Mechanical properties of the plastic material
Number of times to be assembled or disassembled
Stress and strain that the clip to be withstand
   during assembly
Mechanical pressure applied to the clip after assembly
 


1. Reasonable lengths

2. To avoid stress concentration by adding round corners or fillets at the base of the clips



3. Clips shall be evenly distributed

4. Use positioning columns to assist the clip assembly



5. Well-designed clips should not increase mold complexity

6. Well-designed clips shall be easy for mold modification
