Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If water cooling is used to improve heat dissipation, then heat dissipation efficiency is improved, but device complexity increases
Solution Approach 1:
The patent merges the cooling function directly into the power supply module structure by integrating the water cooling plate with the housing. The water cooling plate is formed as an integral part of the module structure, combining thermal management with structural support functions, thereby improving heat dissipation while minimizing the increase in device complexity.
Solution Approach 2:
The water cooling plate serves multiple functions: it acts as both a thermal management component for cooling power electronic devices and as a structural element forming part of the module housing. This multi-functionality allows the system to achieve effective heat dissipation without adding separate dedicated cooling structures, thus controlling device complexity.
2Productivity
If power density is increased, then productivity is improved, but electromagnetic interference increases
Solution Approach 1:
The patent segments the power supply module into functionally isolated sections: a power component region containing high-power devices, a control component region for low-power control circuits, and a water cooling plate region. This spatial segmentation allows high power density in the power region while isolating electromagnetic interference from the control region, preventing interference propagation.
Solution Approach 2:
The patent applies local quality differentiation by providing enhanced shielding and isolation specifically in the control component region, while allowing higher power density in the power component region. The control region is positioned away from high-current paths and provided with additional electromagnetic shielding, creating locally optimized zones with different quality characteristics suitable for their specific functions.
3Ease of operation
If control module is positioned above power module, then ease of operation is improved, but electromagnetic interference increases
Solution Approach 1:
The patent introduces an insulating pad as an intermediary element positioned between the control module and the power module. This insulating pad serves as a mediator that provides electrical isolation and electromagnetic shielding, allowing the control module to be positioned above the power module for ease of assembly and signal routing while preventing harmful electromagnetic coupling and signal disturbance.
4Volume of moving object
If compact structure is achieved, then space utilization is improved, but heat dissipation becomes more difficult
Solution Approach 1:
The patent implements a nested arrangement where the water cooling plate is integrated within the module housing structure, and power electronic devices are mounted on or above the cooling plate. This nesting allows the cooling function to be embedded within the structural framework rather than adding external cooling components, achieving compact space utilization while maintaining effective heat dissipation pathways through the integrated cooling plate.
