Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the duty cycle of switching elements is adjusted to control supply power, then the supply power can be controlled, but power fluctuations occur and energy efficiency is reduced
Solution Approach 1:
The patent applies dynamics by making the switching parameters adaptive rather than fixed. The control unit dynamically adjusts switching parameters based on operating conditions to optimize power delivery and minimize energy losses. This is achieved through real-time modification of switching behavior in response to system state changes.
Solution Approach 2:
The patent implements parameter changes by modifying switching parameters (such as duty cycle, switching frequency, or phase angle) to control and optimize supply power. The control unit varies these parameters according to the desired power level and operating conditions, enabling precise power adjustment while maintaining energy efficiency.
2Power
If the duty cycle of switching elements is adjusted to control supply power, then the supply power can be controlled, but power supply stability is reduced
Solution Approach 1:
The patent employs feedback mechanisms where the control unit monitors the actual power delivery and switching element behavior, then adjusts switching parameters accordingly. This closed-loop control ensures stable power supply by compensating for fluctuations and maintaining consistent output despite varying operating conditions.
Solution Approach 2:
The system uses dynamic parameter adjustment to maintain stability across different operating states. By continuously adapting switching parameters based on real-time conditions, the system achieves both power control flexibility and supply stability.
3Device complexity
If the duty cycle of exclusively one switching element is changed to adjust supply power, then the control is simplified, but the power adjustment range is limited
Solution Approach 1:
The patent segments the power control function by independently controlling different switching elements for different power ranges or operating modes. This allows one switching element to handle specific power ranges while others manage different ranges, achieving both simplified control logic within each segment and extended overall power adjustment range through coordination of multiple segments.
Solution Approach 2:
The switching elements are designed to serve multiple functions: primary power control, auxiliary power adjustment, and operational mode selection. This multi-functionality allows the system to achieve a wide power adjustment range while maintaining relatively simple control structures through unified control architecture.
