Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If fast-charge function is enabled, then charging speed is improved, but battery life is shortened and battery capacity is wasted
Solution Approach 1:
The patent implements dynamic switching between fast-charge mode and normal-charge mode based on real-time detection of leakage events. The charge mode is not fixed but adapts to system conditions, allowing the system to use fast-charge when safe and switch to normal-charge when leakage is detected, thus resolving the contradiction between charging speed and battery life
Solution Approach 2:
The patent employs a feedback mechanism where the management chip continuously monitors the system for leakage events and adjusts the charge mode accordingly. When leakage is detected, the system provides feedback to switch from fast-charge to normal-charge mode, and can revert to fast-charge when the leakage condition is resolved, optimizing both charging speed and battery longevity
2Duration of action of moving object
If battery capacity is increased, then stand-by time and usage time are extended, but leakage causes electric quantity consumption and reduces usage time
Solution Approach 1:
The patent implements preliminary detection of leakage events before they cause significant battery drainage. The management chip continuously monitors the system state and proactively switches to normal-charge mode or enters temporary failure state when leakage is detected, preventing the waste of increased battery capacity before it occurs
Solution Approach 2:
The patent converts the potential harm of leakage-induced battery drainage into a benefit by using the leakage detection mechanism to trigger charge mode switching. The leakage event, which would normally waste battery capacity, instead serves as a signal to switch to a more conservative charge mode, thereby protecting the increased battery capacity from being wasted
3Duration of action of moving object
If leakage detection and prevention functions are added, then battery life and usage time are improved, but device complexity increases
Solution Approach 1:
The patent integrates leakage detection and charge mode management functions into the existing battery management chip, making the chip perform multiple functions: normal battery management, leakage detection, and dynamic charge mode switching. This multi-functionality approach adds leakage protection capabilities without requiring completely separate dedicated hardware components, thus limiting the increase in device complexity
