Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rigid conductive wires are fixedly connected to conductive terminals, then electrical connectivity is maintained, but design freedom and positioning flexibility are restricted
Solution Approach 1:
The patent replaces rigid fixed connections with dynamic spring-based conductive members that can move and deform. The springs are configured to maintain constant contact with conductive terminals while allowing relative movement, enabling both design flexibility and reliable electrical connectivity simultaneously.
Solution Approach 2:
The conductive members transition from rigid wires to elastic springs, changing the physical state from rigid to flexible. This parameter change allows the conductive members to adapt to different positions and orientations while maintaining electrical contact, resolving the contradiction between design freedom and connectivity reliability.
2Stability of the object's composition
If conductive wires are made rigid and fixedly connected, then structural stability is achieved, but twisting and entanglement occur during displacement
Solution Approach 1:
The patent uses flexible spring-based conductive members instead of rigid wires. These springs can bend and deform to accommodate relative movement between components, preventing twisting and entanglement while maintaining structural stability through their elastic properties.
Solution Approach 2:
The springs are designed to dynamically adapt to movement and displacement, allowing the conductive members to flex and reposition themselves during operation. This dynamic behavior prevents the twisting and entanglement that would occur with rigid fixed connections.
3Ease of manufacture
If rigid wires are used for electrical connection, then manufacturing simplicity is maintained, but positioning precision and flexibility are reduced
Solution Approach 1:
The spring-based conductive members are designed to self-position through their elastic deformation. The springs naturally conform to the available space and maintain optimal contact positions, achieving high positioning precision without complex manufacturing processes.
Solution Approach 2:
The springs automatically adjust their position and orientation based on the relative movement between components. This self-adjusting capability eliminates the need for precise pre-positioning during manufacturing, maintaining manufacturing simplicity while achieving high positioning precision during operation.

AI summary
A conductive mechanism includes two bases, an inner conductive spring and an outer conductive spring. The two bases are opposite to each other. Each of the bases includes a surface and a partition wall protruding relative to the surface. The inner conductive spring is disposed at inner sides of the two partition walls of the two bases. The outer conductive spring is disposed at outer sides of the two partition walls of the two bases. At least one of two ends of each of the inner conductive spring and the outer conductive spring rotatably abuts against the surface of one of the bases.
