Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If battery boards are removed for diagnosis, then diagnosis accuracy is improved, but system operation continuity deteriorates
Solution Approach 1:
The patent introduces other battery boards as intermediary power sources to provide compensation power during diagnosis. Instead of removing the battery board under test, the system uses functional battery boards as mediators to maintain power balance, enabling in-situ diagnosis without affecting system operation or grid stability.
2Ease of repair
If battery boards are removed for diagnosis, then component inspection capability is improved, but power grid stability deteriorates
Solution Approach 1:
The patent ensures continuous power compensation during diagnosis operations. By dynamically adjusting the charge/discharge status of other battery boards, the system maintains continuous power balance, allowing component inspection to proceed without interrupting power grid connection or compromising grid stability.
3Ease of operation
If power compensation is performed between battery boards, then in-operation diagnosis is enabled, but control complexity increases
Solution Approach 1:
The patent implements a feedback control mechanism where the management device continuously monitors the charge/discharge status of battery boards and dynamically adjusts power compensation. The control device receives status information and automatically calculates required compensation power, reducing manual intervention complexity while enabling in-operation diagnosis.
