Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid twisted wires are tightly clipped by an elastic sheet, then wire connection stability is improved, but the number of contact points is limited to one or two
Solution Approach 1:
The electrical conducting contact surface is segmented into multiple contact regions through protrusions and inclined surfaces, transforming a single contact interface into multiple discrete contact points. This segmentation allows the rigid twisted wire to engage with multiple contact surfaces simultaneously, increasing the number of contact points from one or two to multiple points while maintaining connection stability.
Solution Approach 2:
The invention introduces dimensional complexity to the contact surface by adding protrusions with inclined surfaces that extend in multiple directions. This transforms a simple planar contact into a multi-dimensional contact structure, enabling the wire to make contact at multiple locations along the inclined surfaces, thereby increasing contact points without compromising stability.
2Ease of manufacture
If a planar electrical conducting contact surface is used, then manufacturing is simple, but current flowing capability is poor
Solution Approach 1:
Instead of making the entire contact surface complex, the invention applies local quality changes by adding protrusions and inclined surfaces only at specific locations on the contact surface. This localized modification increases current flowing capability through multiple contact points while keeping the overall manufacturing process relatively simple, as the base structure remains planar with localized features added.
