Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If preset fixed adjustment factors are used for battery voltage control, then the control logic is simple, but the battery application flexibility is poor and usage duration is shortened
Solution Approach 1:
The patent transforms fixed adjustment factors into dynamic adjustable factors. The first and second adjustment factors are no longer preset constants but are dynamically adjusted based on real-time battery state (charge/discharge status, temperature, voltage deviation). This enables the control system to adapt to different application scenarios while maintaining manageable complexity through structured adjustment mechanisms.
Solution Approach 2:
The patent changes the parameters of the adjustment factors from fixed values to variable values that can be modified based on battery operating conditions. By allowing the adjustment factors to change according to temperature, charge state, and voltage deviation, the system achieves better adaptability without requiring complete redesign of the control logic.
2Duration of action of moving object
If fixed discharge voltage control is implemented, then the control implementation is simple, but the battery usage duration is reduced
Solution Approach 1:
The patent implements feedback mechanisms where the actual output voltage is continuously monitored and compared with the target output voltage. The difference (deviation) is fed back to adjust the first and second adjustment factors, creating a closed-loop control system that optimizes battery usage duration while managing complexity through systematic feedback processing.
Solution Approach 2:
The control system performs self-adjustment by automatically modifying the adjustment factors based on the voltage deviation feedback. The system serves itself by detecting its own state and making necessary corrections without external intervention, thereby extending battery usage duration while maintaining controlled complexity.
3Duration of action of moving object
If dynamic adjustment of factors is implemented, then battery usage duration is extended, but the control system complexity increases
Solution Approach 1:
The patent segments the voltage control into distinct phases (charging and discharging) with separate adjustment factors (first and second adjustment factors). Each factor can be independently adjusted based on specific conditions, which manages complexity by breaking down the overall control into manageable segments rather than requiring a single complex control mechanism.
4Stability of the object's composition
If real-time voltage monitoring and adjustment is performed, then output voltage stability is improved, but the processing overhead increases
Solution Approach 1:
The patent combines voltage monitoring, deviation calculation, and factor adjustment into an integrated control process. By merging these functions into a unified real-time control mechanism, the system achieves stable output voltage while minimizing processing overhead through efficient consolidation of operations rather than separate sequential processing.
