Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic strips are used to ensure current flow for electrophoretic painting, then conductivity is achieved, but device complexity and manufacturing cost increase due to drilling holes and assembling magnetic strips
Solution Approach 1:
The patent combines the conductivity function and structural support function into a single integrated bearing point component made of conductive metal material. The bearing point directly provides the necessary current flow path without requiring separate magnetic strips, thereby eliminating the need for additional drilling and assembly operations while maintaining reliable electrical conductivity for electrophoretic painting.
Solution Approach 2:
The bearing point is designed to serve multiple functions simultaneously: it provides mechanical support for the tailgate or front lid, enables pivoting movement, and ensures electrical conductivity for the electrophoretic painting process. This multi-functional design eliminates the need for separate components like magnetic strips, reducing assembly complexity while maintaining all necessary functions.

3Reliability
If a conductive metal bearing point is used, then current flow is ensured and manufacturing is simplified, but friction during pivoting may increase
Solution Approach 1:
The patent introduces a bearing element (such as a bearing bush or roller bearing) as an intermediary component between the bearing point and the tailgate or front lid. This bearing element mediates the contact during pivoting movement, reducing friction and wear while allowing the conductive bearing point to maintain its electrical conductivity function. The bearing element acts as a mediator that separates the conductivity function from the friction-prone mechanical contact.
