Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a voltage adjustment module is added between the LLC module and LED light strip to adjust the voltage, then the voltage provided to the LED light strip can be adjusted, but the power supply circuit becomes more complex and costly
Solution Approach 1:
The patent combines the voltage adjustment function with the existing power supply branches by introducing a power adjustment module that controls energy transfer between branches. This merges the voltage regulation capability into the existing circuit architecture rather than adding a separate adjustment module, thereby reducing overall circuit complexity while maintaining adaptability.
Solution Approach 2:
The power adjustment module serves multiple functions: it adjusts voltage for the LED light strip, maintains stability for the main board, and optimizes overall power distribution. By making the power supply system multi-functional, the patent reduces the need for separate dedicated adjustment circuits, thereby simplifying the overall design.
2Adaptability or versatility
If significant voltage adjustments are made to supply power to LED light strips, then the voltage can be matched to LED requirements, but the power supply efficiency decreases
Solution Approach 1:
The patent implements dynamic voltage adjustment by controlling energy transfer between power supply branches in real-time based on load conditions. This dynamic approach allows the system to optimize voltage distribution continuously, minimizing energy losses that would occur with static or excessive voltage adjustments.
Solution Approach 2:
The system changes operational parameters by adjusting the energy transfer ratio between branches rather than making significant absolute voltage changes. This parameter-based adjustment approach allows for fine-tuned voltage matching to LED requirements while minimizing energy conversion losses.
3Adaptability or versatility
If multiple power supply branches are used to supply different voltages, then different loads can be powered appropriately, but the circuit structure becomes more complex
Solution Approach 1:
The patent introduces a power adjustment module as an intermediary that controls energy transfer between the first and second power supply branches. This intermediary component provides a centralized control mechanism that simplifies the management of multiple voltage outputs, reducing the overall circuit complexity compared to having independent adjustment circuits for each branch.
