Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional unidirectional BMS is used, then the system structure is simple and hardware cost is low, but the battery management capability and adaptability are limited
Solution Approach 1:
The patent merges the BMS with the application processor by integrating the fuel gauge functionality into the application processor. This combination allows the BMS to access system resources and communicate bidirectionally with the OS, enhancing battery management capabilities while reducing hardware complexity through resource sharing.
Solution Approach 2:
The application processor is designed to perform multiple functions including both general computing tasks and specialized battery management functions. By making the application processor universal, it can handle diverse workloads while also providing advanced battery management capabilities through integrated fuel gauge functionality.
2Duration of action of stationary object
If a conventional unidirectional BMS is used, then the hardware cost is reduced, but the ability to optimize charging and extend battery life is restricted
Solution Approach 1:
The patent implements bidirectional communication between the BMS and the OS, enabling the system to receive feedback about device usage patterns, application requirements, and environmental conditions. This feedback loop allows the BMS to dynamically adjust charging strategies, optimize battery performance, and extend battery life based on real-time system state.
Solution Approach 2:
The BMS uses bidirectional communication to obtain advance information about future device usage patterns and application requirements. This preliminary information allows the system to proactively optimize charging schedules and battery management strategies before actual usage occurs, thereby extending battery life.
3Adaptability or versatility
If bidirectional communication is implemented, then the battery management capability is enhanced, but the device complexity increases
Solution Approach 1:
The patent resolves the complexity issue by merging the BMS functionality into the application processor rather than maintaining separate hardware components. This integration enables bidirectional communication and enhanced adaptability while reducing overall system complexity through shared hardware resources and unified control architecture.
