Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a plurality of capacitors connected in parallel are electrically connected to an aging apparatus to subject them to aging simultaneously, then productivity is improved, but reliability deteriorates due to inability to verify electrical connection between connection terminals and connectors
Solution Approach 1:
The patent implements a preliminary electrical connection verification step before aging processing. The verification unit checks electrical continuity between connection terminals and connectors through the capacitors in parallel, ensuring reliable connections are established before voltage is applied for aging. This preliminary action prevents undetected connection failures from compromising the entire aging process.
Solution Approach 2:
The patent incorporates a feedback mechanism where the verification unit continuously monitors electrical connection status and provides feedback to the control unit. If connection failures are detected during the verification process, the system can identify and address specific faulty connections before proceeding with aging, ensuring that all capacitors receive proper voltage application.
2Reliability
If electrical connection between aging apparatus and capacitor electrodes is checked before aging processing, then reliability is improved, but device complexity increases due to additional verification components
Solution Approach 1:
The patent designs the verification unit to perform multiple functions: it verifies electrical continuity between connection terminals and connectors, identifies specific faulty connections, and provides feedback for process control. By making this single unit multi-functional, the patent avoids needing separate verification systems for each function, thereby reducing overall device complexity while maintaining high reliability.
Solution Approach 2:
The verification unit utilizes the existing electrical paths through the capacitors themselves to perform self-verification. By measuring electrical continuity through the capacitor array, the system uses the capacitors' own structure as part of the verification mechanism, eliminating the need for additional external verification equipment and reducing overall system complexity.
