Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a compression spring structure is used to fix the copper sheet, then the copper sheet can be supported and maintain contact with the copper bar, but the copper sheet deforms and loses resilience after installation, making repeated installation difficult
Solution Approach 1:
The patent introduces a movable power supply structure that can dynamically adjust its position. The power supply structure includes a convex portion that moves along the track to maintain contact with the power transmission bar, allowing the system to adapt to installation variations and facilitate repeated installation without permanent deformation.
Solution Approach 2:
The patent changes the physical state of the power supply structure from fixed to movable. By allowing the power supply structure to move and return to its initial state, the system maintains elastic deformation capabilities, enabling repeated installation and contact stability without the copper sheet losing resilience.
2Reliability
If the copper sheet is fixed with a compression spring structure, then power transmission can be maintained, but the structure becomes complex and the copper sheet cannot be easily repositioned
Solution Approach 1:
The patent divides the electrical connection into separate functional components: the substrate provides mounting, the power supply structure provides power transmission with a movable convex portion, and the elastic member provides restoring force. This segmentation allows each component to perform its function independently, reducing overall structural complexity while maintaining reliability.
Solution Approach 2:
The elastic member acts as an intermediary between the fixed substrate and the movable power supply structure. It provides the necessary restoring force to return the power supply structure to its initial state after deformation, simplifying the overall mechanism while ensuring reliable power transmission contact.
3Ease of operation
If the copper sheet is deformed to fit the track, then installation is achieved, but the copper sheet cannot be reused due to permanent deformation
Solution Approach 1:
The power supply structure is designed to be movable rather than fixed. The convex portion can move along the track during installation and return to its initial state, allowing the copper sheet to be deformed for installation and then reused without permanent deformation affecting functionality.
Solution Approach 2:
The elastic member enables the power supply structure to be temporarily deformed during installation and then recovered to its initial state. This recovering mechanism allows the copper sheet and power supply structure to be reused multiple times without losing their functional properties.

Function Achieved in This Case
The design ensures stable power connection and facilitates repeated installation by allowing the power supply structure to move and return to its initial state, avoiding deformation and enhancing reliability.
Implementation Method 1
the elastic member may be configured to generate elastic deformation in a case that the convex portion and the power transmission bar are pressed against each other, so that the convex portion and the power transmission bar may be kept abutting against with each other
