Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminal conductors and wiring conductors are used to connect the circuit substrate to the connector, then electrical connection is achieved, but the number of components increases and weight increases
Solution Approach 1:
The patent integrates the terminal conductor and wiring conductor functions into a single integrated conductor structure. The terminal conductor is formed as an integral part of the circuit substrate, eliminating the need for separate wiring conductors and reducing the total number of components while maintaining electrical connection reliability.
Solution Approach 2:
The integrated conductor structure serves multiple functions simultaneously: it acts as both the terminal conductor for external connections and the wiring conductor for internal circuit connections. This multi-functional design reduces component count while achieving the same electrical connectivity.
2Reliability
If terminal conductors and wiring conductors are used with multiple connection operations, then electrical connection is established, but assembly operation complexity increases
Solution Approach 1:
The patent combines multiple assembly operations into a single integrated structure. The terminal conductor is pre-formed as part of the circuit substrate, eliminating the need for separate connection operations between terminal conductors and wiring conductors, thereby simplifying assembly while maintaining connection reliability.
3Reliability
If multiple connection portions are used to connect terminal conductors and wiring conductors, then electrical connectivity is achieved, but reliability of endurance decreases
Solution Approach 1:
The patent merges multiple connection portions into a single integrated conductor structure. By eliminating the interfaces between separate terminal conductors and wiring conductors, the design reduces the number of potential failure points and improves endurance reliability while maintaining electrical connectivity.
