Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fast charging function is enabled to achieve rapid battery charging, then charging speed is improved, but risk of abnormal charging and safety hazards increases
Solution Approach 1:
The patent applies preliminary action by detecting battery charging parameters (voltage, current, temperature) before and during the fast charging process to identify potential abnormalities early. The terminal detects these parameters continuously and determines whether abnormal charging occurs before serious safety issues arise, allowing preventive action to be taken.
Solution Approach 2:
The patent implements feedback by continuously monitoring battery charging parameters during fast charging and using this information to control the charging process. When abnormal charging is detected through parameter analysis, the system provides feedback to turn off the fast charging function, creating a closed-loop control system that balances charging speed with safety.
2Productivity
If fast charging is performed with high current to reduce charging time, then charging efficiency is improved, but current loss through leakage paths increases
Solution Approach 1:
The patent uses feedback by continuously detecting battery charging parameters including current and comparing them against expected values. When current loss or leakage is detected through parameter analysis, the system adjusts or terminates the fast charging to prevent energy loss, maintaining charging efficiency while minimizing waste.
Solution Approach 2:
The patent replaces physical inspection methods with electrical parameter detection and analysis. Instead of mechanical checks for leakage paths, the system uses electronic detection of charging parameters (voltage, current, temperature) to identify and respond to abnormal charging conditions, enabling more precise and rapid detection.
3Reliability
If continuous monitoring of battery parameters is implemented to ensure safety, then charging reliability is improved, but system complexity increases
Solution Approach 1:
The patent applies universality by using the existing battery management system components to perform multiple functions. The same detection circuits and processors used for normal battery management are utilized for abnormal charging detection, eliminating the need for separate dedicated monitoring hardware and reducing overall system complexity while maintaining safety.
Solution Approach 2:
The patent implements self-service by enabling the terminal's existing battery management system to autonomously detect and determine abnormal charging conditions without requiring external monitoring equipment. The system uses its own built-in capabilities to monitor charging parameters and make safety decisions, simplifying the overall architecture.
