Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual welding is used to connect irregularly arranged leads to connector terminals, then connection flexibility is achieved, but assembly efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-arranging the leads in a regular, comb-like configuration before the welding process. The leads are positioned in advance within a comb structure that aligns them with corresponding connector terminals, eliminating the need for manual positioning during assembly and significantly improving assembly efficiency while maintaining connection flexibility.
2Ease of manufacture
If shielding layer is peeled off to facilitate lead welding, then welding accessibility is improved, but electromagnetic interference resistance deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the cable structure into distinct functional zones: a shielded section for signal transmission and an unshielded comb section for automated lead arrangement and welding. The comb structure is positioned such that only minimal portions of leads require exposure, and even these are protected where possible. This segmentation allows welding accessibility in the comb region while preserving electromagnetic interference resistance in the main cable transmission sections.
3Ease of operation
If relay circuit board is added to connect coaxial wire and connector, then welding operation convenience is improved, but device complexity and signal integrity deteriorate
Solution Approach 1:
The patent applies merging by integrating the lead arrangement and connection functions directly into the comb structure formed by the leads themselves, rather than using a separate relay circuit board. The comb-like arrangement of leads serves both as the structural organizer and as the electrical connection medium, eliminating the need for additional circuit boards and reducing overall device complexity while maintaining welding operation convenience through automated positioning.
