Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a projecting part is arranged on the insulated body to provide against surface, then the against effect is improved, but the space is wasted due to the size of the projecting part
Solution Approach 1:
The patent extracts the against function from a separate projecting part and integrates it into the receiving hole structure itself. The first wall of hole serves as the against surface, eliminating the need for an additional projecting part and thus saving space while maintaining the against effect.
Solution Approach 2:
The patent merges the against surface function with the receiving hole structure by making the first wall of hole serve dual purposes: both as a structural boundary for the receiving hole and as the against surface for the electronic component. This integration eliminates wasted space.
2Reliability
If constricted connection is used between conductive terminal and chip module, then electrical connection is established, but the conductive terminal and chip module are easy to get damage after long-term constriction
Solution Approach 1:
The patent changes the geometric parameters of the receiving hole, specifically making the first wall of hole higher than the second wall of hole. This parameter change creates asymmetric clearance that allows the conductive terminal to be positioned optimally, reducing excessive constriction force while maintaining electrical connection reliability.
Solution Approach 2:
The patent applies different wall heights at different locations of the receiving hole. The first wall of hole has greater height to provide clearance and reduce constriction force, while the second wall of hole has lesser height to maintain proper positioning. This local differentiation optimizes both connection reliability and damage resistance.
3Object-affected harmful factors
If the first wall of hole is made higher than the second wall of hole, then the against effect is improved and space is saved, but the manufacturing precision requirement increases
Solution Approach 1:
The patent segments the receiving hole into two distinct wall structures with different heights. This segmentation allows each wall to be optimized independently for its specific function while the overall structure remains integrated in the insulated body, balancing manufacturing feasibility with functional requirements.
