Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If transformers and electronic components are configured independently on a circuit board, then the power supply device can be assembled and maintained easily, but the overall volume cannot be miniaturized and circuit complexity increases
Solution Approach 1:
The patent integrates the transformer and electronic components into a single integrated power conversion module. The transformer windings are directly formed on the circuit board as integrated circuits, and electronic components are mounted on the same board, merging previously separate elements into one unified structure. This reduces overall volume while the integration is performed in a systematic way that manages circuit complexity.
Solution Approach 2:
The patent utilizes the z-dimension (vertical space) by stacking components and using multi-layer circuit board structures. The transformer windings are formed in multiple layers on the circuit board, and components are arranged in three-dimensional space rather than only planar configuration, enabling miniaturization without excessive planar complexity.
2Ease of manufacture
If transformers and electronic components are configured independently on a circuit board, then the power supply device can be assembled and maintained easily, but the hardware costs increase
Solution Approach 1:
By integrating multiple components into a single module, the patent reduces the total quantity of discrete components needed, thereby reducing hardware costs. The integrated power conversion module combines the transformer, rectifier circuits, and control components into one unit, reducing component count and assembly steps while maintaining ease of manufacture through standardized integration processes.
3Adaptability or versatility
If multiple power supply modules are used for different AC voltages, then the power supply device can adapt to different voltage inputs, but the device complexity and volume increase
Solution Approach 1:
The integrated power conversion module is designed with universal functionality to handle different AC voltage inputs. The module incorporates switching circuits and control logic that can adapt to various voltage levels without requiring separate dedicated modules for each voltage type. This multi-functional design achieves voltage adaptability while maintaining compact size.
Solution Approach 2:
The power conversion module employs dynamic switching and control mechanisms that can adjust its operation based on the input voltage level. The switching control module dynamically reconfigures the circuit topology and switching parameters to optimize performance for different voltage inputs, enabling adaptability without requiring multiple fixed-configuratio n modules.
