Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional vehicle side electrical connector with fixed pole is used, then electrical connection can be established, but the pole is easily damaged when suffering vertical extrusion force
Solution Approach 1:
The patent transforms the fixed rigid pole into a flexible cable assembly that can dynamically adapt to vertical extrusion forces through bending and deformation, preventing damage while maintaining electrical connection stability
Solution Approach 2:
The patent replaces the rigid pole with a flexible cable structure that has bending resistance, allowing it to absorb vertical extrusion forces through elastic deformation without suffering hard damage
2Stability of the object's composition
If rigid electrical connection structure is used, then connection stability is maintained, but damage occurs under vertical extrusion force
Solution Approach 1:
The flexible cable assembly acts as a cushioning element that absorbs vertical extrusion forces before they can transmit damage to the electrical connection components, protecting the system in advance
3Object-affected harmful factors
If detachable seal connection between mounting seats is implemented, then waterproof performance is improved, but device complexity increases
Solution Approach 1:
The patent combines the sealing function with the mounting seat structure itself, integrating the seal into the existing components rather than adding separate sealing mechanisms, thus improving waterproof performance without significantly increasing complexity
