Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If an EI transformer is used for voltage conversion, then voltage conversion function is achieved, but the weight and size increase significantly
Solution Approach 1:
The patent replaces the traditional EI transformer with an electronic voltage conversion circuit comprising a rectifying element, filtering element, and control unit. This substitution eliminates the need for heavy magnetic components while achieving the same voltage conversion function through electronic means, thereby significantly reducing weight and size.
Solution Approach 2:
The invention changes the operating parameters and working mode of the power supply system by transitioning from transformer-based electromagnetic conversion to electronic switching conversion. This parameter change enables high-frequency operation with smaller components, reducing both weight and volume while maintaining power conversion capability.
2Power
If an EI transformer is used for voltage conversion, then voltage conversion function is achieved, but environmental compatibility deteriorates
Solution Approach 1:
The patent replaces the EI transformer with an electronic voltage conversion circuit that operates more efficiently and generates less electromagnetic interference and heat. This substitution improves environmental compatibility by reducing harmful emissions and energy losses associated with traditional transformer-based power supplies.
3Ease of operation
If a modular structure is maintained, then ease of assembly and maintenance is improved, but accommodating new components becomes difficult
Solution Approach 1:
The patent designs a universal power supply module where the control unit and voltage conversion circuit can accommodate different component configurations. The modular structure includes standardized interfaces and mounting arrangements that allow new components to be integrated without compromising the modular advantage, enabling both ease of assembly and adaptability to new technologies.
Solution Approach 2:
The invention divides the power supply system into independent modular units including a control unit module and a voltage conversion module. Each module can be independently designed, assembled, and replaced. This segmentation allows new components to be accommodated within specific modules while maintaining the overall modular structure and its associated ease of assembly and maintenance benefits.
