Engineering Contradiction Analysis
1Reliability
If a fixed voltage analog reference is used to control the power supply chip, then the drive chip receives stable voltage signals, but the power supply chip cannot maintain optimal output efficiency as electricity quantity decreases
Solution Approach 1:
The patent implements dynamic adjustment of the analog reference voltage based on real-time detection of battery electricity quantity. The drive chip dynamically modifies the analog reference voltage signal according to the detected electricity quantity, enabling the power supply chip to operate at optimal efficiency across varying battery conditions rather than using a fixed voltage reference.
Solution Approach 2:
The patent introduces a feedback mechanism where the drive chip detects the electricity quantity of the battery and uses this information to adjust the analog reference voltage. This closed-loop feedback system allows the power supply chip to adapt its operation based on actual battery conditions, maintaining optimal efficiency while preventing excessive energy loss.
2Device complexity
If the analog reference voltage is kept fixed, then the power supply chip operation is simplified, but output efficiency continuously changes and cannot be maintained at optimal value
Solution Approach 1:
The patent transforms the static analog reference voltage into a dynamic parameter that adjusts according to battery electricity quantity. The drive chip modifies the reference voltage level based on detected electricity quantity, allowing the power supply chip to maintain high output efficiency across different operating conditions without requiring complex external control circuits.
Solution Approach 2:
The drive chip performs self-adjustment by detecting its own operating conditions (electricity quantity) and automatically modifying the analog reference voltage accordingly. This self-service mechanism eliminates the need for external control systems while maintaining optimal power supply efficiency.
3Use of energy by moving object
If electricity quantity decreases, then power consumption reduces, but output efficiency of power supply chip deteriorates and electricity loss increases
Solution Approach 1:
The patent changes the analog reference voltage parameter based on electricity quantity detection. When electricity quantity decreases, the drive chip adjusts the reference voltage to a level that maintains optimal conversion efficiency in the power supply chip, preventing excessive energy loss even at lower power consumption levels.
Solution Approach 2:
The patent implements a feedback loop that continuously monitors electricity quantity and adjusts the analog reference voltage to prevent energy loss. This feedback mechanism ensures that the power supply chip operates efficiently across the entire range of electricity quantities, from full to low power states.
