Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the battery is used continuously without performance control, then the device can operate for extended periods, but the internal resistance increases causing voltage variations and reduced reliability
Solution Approach 1:
The patent adjusts the full charge voltage parameter based on the number of charge-discharge cycles. As the battery ages and internal resistance increases, the system dynamically modifies the charging voltage threshold to maintain optimal performance and reliability throughout the battery's lifespan
Solution Approach 2:
The system monitors the number of charge-discharge cycles and uses this feedback to adjust battery management parameters. The processor tracks usage patterns and modifies charging behavior accordingly, creating a closed-loop control system that adapts to battery degradation
2Productivity
If the full charge voltage is maintained at initial levels throughout battery life, then charging efficiency is maximized initially, but battery degradation accelerates reducing overall device reliability
Solution Approach 1:
The patent transforms the static full charge voltage parameter into a dynamic one that changes with battery age and usage patterns. The system adapts the charging voltage threshold based on accumulated charge-discharge cycles, optimizing both charging efficiency and battery longevity throughout its operational life
Solution Approach 2:
The system proactively adjusts charging parameters before significant battery degradation occurs. By monitoring cycle counts and preemptively modifying full charge voltage thresholds, the system prevents excessive stress on aging batteries while maintaining acceptable charging performance
