Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If contact elements are connected through non-detachable connections, then structural stability is improved, but assembly complexity and difficulty increase
Solution Approach 1:
The contact element is divided into separate functional components: a body with multiple contact points and individual spring arms for each contact point. This segmentation allows each spring arm to be independently attached and adjusted, simplifying assembly while maintaining structural stability through the unified body structure.
Solution Approach 2:
The spring arms provide dynamic, detachable connections instead of rigid non-detachable connections. The spring mechanism allows for easy attachment and detachment while maintaining stable electrical contact during operation, resolving the contradiction between stability and assembly complexity.
2Ease of operation
If spring arms are designed separately from a common base, then ease of operation and reliability improve, but device complexity increases
Solution Approach 1:
Each spring arm is designed as a separate component that can be independently attached to the common base. This segmentation enables easy assembly and disassembly of individual spring arms without affecting other contact points, improving ease of operation while the modular design keeps overall complexity manageable.
Solution Approach 2:
The common base serves as a universal mounting structure for multiple spring arms, providing a standardized interface that simplifies the overall design. This universal base reduces complexity by consolidating the attachment mechanism while still allowing independent operation of each spring arm.
3Productivity
If multiple contact points are formed in a one-piece contact area, then manufacturing efficiency improves, but functional independence may be compromised
Solution Approach 1:
While the contact points are formed in a one-piece contact area for manufacturing efficiency, each contact point has its own independently mounted spring arm. This segmentation at the functional connection level ensures that mechanical processes at one contact point do not transfer to others, maintaining functional independence and reliability.
Solution Approach 2:
The individual spring arms act as intermediaries between the one-piece contact area and the external contacts. They isolate the mechanical interactions at each contact point while maintaining electrical continuity through the integrated contact area, thus preserving functional independence despite the unified contact structure.
