Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery gauge IC is used to calculate battery power, then power supply function is provided, but rapid fluctuations in estimated power level occur affecting system stability
Solution Approach 1:
The patent applies dynamics by making the slope parameter adjustable based on charging/discharging states. The system dynamically adapts the conversion curve from estimated power to display power according to real-time battery conditions, transforming a static measurement system into a dynamic one that compensates for measurement inaccuracies while maintaining system stability.
Solution Approach 2:
The patent changes the parameter of the conversion function by introducing an adjustable slope parameter. This parameter modifies the relationship between estimated power and display power, allowing the system to compensate for measurement fluctuations by adjusting the conversion characteristics based on charging/discharging states rather than using a fixed conversion ratio.
2Ease of operation
If fixed conversion method is used from estimated power to display power, then simple implementation is achieved, but rapid power changes and jumps occur
Solution Approach 1:
The system transitions from a static fixed conversion method to a dynamic conversion method where the slope parameter changes based on charging/discharging states. This maintains ease of operation through automated adjustment while improving power display stability by adapting to real-time battery conditions.
Solution Approach 2:
The system implements feedback by monitoring the charging/discharging state and using this information to adjust the slope parameter in the conversion function. This closed-loop approach ensures that the conversion from estimated power to display power responds to actual battery conditions, preventing rapid power changes while maintaining simple implementation through automated control.
