Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If contact force is transmitted through the printed circuit board insulation material to the comb tines, then the comb tines can be clamped in the electrical connection terminals, but the insulation material becomes overloaded and mechanically stressed
Solution Approach 1:
A metal support part is introduced as an intermediary element between the pressure piece and the comb tine. This metal support part receives the contact force from the pressure piece and transmits it to the comb tine, thereby mediating the force transmission and preventing direct loading of the insulation material.
Solution Approach 2:
The solution combines different materials (metal support part and insulation material) in a composite structure. The metal support part provides mechanical strength for force transmission, while the insulation material maintains its electrical insulation function without bearing mechanical loads.
2Force
If metal support parts are integrated into the comb tines, then contact force transmission is improved, but the device complexity increases
Solution Approach 1:
The metal support part is merged with the comb tine structure by integrating it directly into the comb tine. This combining of elements achieves improved force transmission while minimizing the increase in device complexity through a unified structural design.
Solution Approach 2:
The metal support part is strategically positioned only at the specific location where force transmission is needed (at the comb tine region subject to contact force), rather than throughout the entire structure. This localized approach improves force absorption without unnecessarily increasing overall device complexity.
