Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional A/D converter with average voltage detection is used, then device complexity is reduced, but measurement precision of battery voltage drops deteriorates
Solution Approach 1:
The detection system is segmented into two independent detectors: a first detector (A/D converter) for measuring average battery voltage and a second detector for detecting temporary voltage drops. Each detector operates independently with its own detection mechanism, allowing the system to maintain low complexity while achieving high measurement precision for both average voltage and voltage drop events.
2Device complexity
If single detector measuring average voltage is used, then device complexity is minimized, but reliability of battery defect detection deteriorates
Solution Approach 1:
The detection function is segmented between two detectors: the first detector monitors overall battery voltage levels while the second detector specifically monitors for temporary voltage drops. This segmentation enables reliable detection of battery defects without requiring a complex unified detection system.
Solution Approach 2:
The controller receives feedback from both detectors and integrates their information to determine battery utility levels. When the second detector detects a voltage drop, it provides feedback that triggers a utility level reduction, ensuring reliable defect detection while maintaining system simplicity.
3Ease of operation
If average voltage detection method is used, then ease of operation is maintained, but loss of information about temporary voltage drops increases
Solution Approach 1:
The detection system is segmented into two specialized detectors: the first detector continues to provide easy-to-interpret average voltage information while the second detector captures temporary voltage drop events. This segmentation preserves operational simplicity while preventing information loss about voltage drops.
Solution Approach 2:
The controller acts as an intermediary that receives information from both detectors and synthesizes the battery utility assessment. It mediates between the average voltage data and temporary drop data, converting both into a unified utility level indication that is easy to interpret while containing complete information.
