Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If water-cool type cooling cabinet is used, then cooling efficiency is improved, but risk of water leakage and electrical hazards increases
Solution Approach 1:
The patent extracts the power supply system into separate modules (power shelf, power distribution boards) and isolates electrical components from water-cooling components. The power shelf converts AC to DC and distributes it through dedicated power distribution boards, creating physical and electrical isolation between water and electricity systems, thereby maintaining cooling efficiency while eliminating electrical hazards from water leakage.
2Device complexity
If alternating current is used for all components, then device complexity is reduced, but safety risk increases due to higher voltage
Solution Approach 1:
The patent changes the electrical parameter from AC to DC for internal components. The power shelf converts AC to DC, and the power distribution boards distribute DC power to fans and other components. This parameter change reduces voltage levels and eliminates the hazards associated with AC power, while the modular power distribution architecture manages the added conversion complexity efficiently.
3Object-affected harmful factors
If DC power is used for fans and components, then safety is improved by reducing voltage, but power conversion complexity increases
Solution Approach 1:
The patent segments the power supply system into distinct functional modules: a power shelf for AC-to-DC conversion, and separate power distribution boards for distributing DC power to different components (fans, pumps, controllers). This segmentation isolates the complexity of power conversion to a dedicated module while simplifying the rest of the system, managing complexity through modular architecture rather than increasing overall system complexity.
