Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If voltage conversion function is integrated into power supply control box, then power supply to devices with different operating voltages is achieved, but arrangement of voltage conversion function lacks optimization
Solution Approach 1:
The patent segments the power supply system into distinct modules: power supply terminal, circuit branch portion, and voltage converter. This segmentation allows each component to be optimized independently while maintaining overall system versatility for different voltage requirements.
Solution Approach 2:
The circuit branch portion acts as an intermediary between the power supply terminal and the voltage converter, enabling flexible routing and distribution of power to multiple devices with different voltage requirements without direct integration complexity.
2Adaptability or versatility
If voltage converter is provided in circuit branch portion, then appropriate power supply to various devices is achieved, but system structure becomes more complex
Solution Approach 1:
The voltage converter is strategically positioned in the circuit branch portion where it is needed, rather than centrally locating all conversion functions. This local placement optimizes voltage adaptation for specific devices while keeping the overall system structure manageable.
Solution Approach 2:
The circuit branch portion is designed with universal connectivity to accommodate multiple devices with different voltage requirements, and the voltage converter can serve multiple downstream devices, providing multi-functionality without proportionally increasing structural complexity.
