Engineering Contradiction Analysis
1Reliability
If existing verification methods are used, then electrical connectivity verification can be performed, but the verification is unreliable due to noise interference
Solution Approach 1:
The patent introduces a dedicated verification apparatus as an intermediary device between the battery pack and the driven device. This apparatus includes a signal generator that creates verification signals and a processor that analyzes the signals, acting as a mediator to perform connectivity verification without being affected by noise from the high-voltage system.
Solution Approach 2:
The patent replaces traditional mechanical connection verification methods with electrical signal-based verification. By using signal generation and processing to detect connectivity status, the system achieves more reliable verification that is not susceptible to mechanical noise or interference from high-voltage environments.
2Reliability
If existing verification methods are used, then connectivity can be checked, but the cost of implementation is high
Solution Approach 1:
The patent divides the verification function into separate modular components: a signal generator module, a processor module, and connection interfaces. This segmentation allows for independent optimization of each component and enables the use of cost-effective individual parts while maintaining overall system reliability.
Solution Approach 2:
The verification apparatus performs self-verification by generating its own test signals and analyzing the responses without requiring external expensive equipment. The integrated design allows the system to serve its own verification needs, reducing dependency on costly external testing infrastructure.
