Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional chip-level voltage bias adjustment is used, then the adjustment process is simple, but the voltage precision is insufficient due to external circuit impacts
Solution Approach 1:
The patent introduces a test board as an intermediary device between the balance module and the external circuit. The test board includes precision reference voltage sources and measurement circuits that isolate the balance module from external circuit impacts, enabling accurate voltage deviation detection and adjustment without being affected by peripheral circuit variations.
Solution Approach 2:
The patent replaces conventional chip-level voltage bias adjustment with a systematic test board-based adjustment method. Instead of relying on chip internal mechanisms that are susceptible to external influences, the system uses external precision voltage references and measurement circuits to achieve accurate voltage deviation detection and correction.
2Ease of operation
If voltage deviation adjustment is performed using conventional methods, then the adjustment can be made, but the adjustment is irreversible and may cause damage or waste of the module
Solution Approach 1:
The patent implements a reversible adjustment mechanism where voltage deviation corrections can be undone if needed. The test board allows for dynamic adjustment where parameters can be modified, tested, and reverted without permanent changes to the balance module, enhancing operational flexibility and safety.
Solution Approach 2:
The patent employs a test board that provides a safe testing environment before final implementation. Voltage deviation adjustments are first tested and validated on the test board, allowing potential issues to be identified and corrected before deploying changes to the actual battery management system, thus preventing damage or waste.
3Device complexity
If conventional voltage bias adjustment is used, then the adjustment process is straightforward, but it cannot make statistics on final test results which is unfavorable for product upgrades
Solution Approach 1:
The patent incorporates comprehensive data collection and feedback mechanisms in the test board. Test results including voltage deviations, adjustment parameters, and module performance data are systematically recorded and fed back for analysis. This enables statistical analysis of final test results, supporting product quality improvement, upgrade decisions, and future development planning.
