Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a battery voltage threshold is set for charger recognition, then the charger can identify charged batteries, but batteries with significantly dropped voltage cannot be recognized or charged
Solution Approach 1:
The system performs preliminary action by detecting batteries with voltage below the threshold and automatically applying a boost voltage before the normal charging process begins. This preliminary voltage enhancement enables the charger to recognize and charge batteries that would otherwise be undetectable, resolving the contradiction between maintaining a detection threshold and charging low-voltage batteries.
Solution Approach 2:
The system changes the voltage parameter dynamically by applying a temporary boost voltage to batteries detected with low voltage. This parameter modification allows the battery to meet the charger's detection threshold requirements, enabling recognition and subsequent charging of previously undetectable batteries.
2Device complexity
If the charger uses a fixed voltage threshold for battery recognition, then detection is simple, but batteries with dropped voltage remain undetected
Solution Approach 1:
The system introduces an intermediary component (voltage boost circuit) between the charger and the low-voltage battery. This intermediary temporarily enhances the battery voltage to meet detection thresholds, allowing the simple fixed-threshold detection system to reliably identify and charge low-voltage batteries without increasing detection complexity.
3Device complexity
If no voltage boost is applied, then the charging system operates simply, but batteries with significantly dropped voltage are not charged
Solution Approach 1:
The system applies preliminary voltage boosting action to undetected or partially charged batteries before initiating the main charging process. This preliminary action ensures that all batteries, including those with significantly dropped voltage, are properly recognized and charged, thereby improving charging completion rate without substantially increasing overall system complexity.
