Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate power support units are configured for different server service functions, then the power supply can meet the specific power demands of each server type, but the device complexity increases and adaptability decreases
Solution Approach 1:
The power support unit is designed with multiple voltage converters that can be dynamically selected and combined to serve different power requirements. The same PSU can power servers with different service functions by activating appropriate voltage converters, eliminating the need for separate PSUs for each server type while maintaining reliable power matching.
Solution Approach 2:
The system dynamically selects and controls voltage converters based on the server's actual power needs. The control unit determines which voltage converters to activate and adjusts their output according to the target power supply power, enabling flexible adaptation to different server types without physical reconfiguration.
2Reliability
If separate power support units are configured for different server service functions, then each server type receives dedicated power support, but the adaptability of power support units decreases
Solution Approach 1:
A single power support unit incorporates multiple voltage converters that can be selectively activated to match different power requirements. This universal design allows the same PSU to serve multiple server types with different service functions, significantly improving adaptability while maintaining stable power supply through controlled activation of appropriate converters.
Solution Approach 2:
The power support unit is segmented into multiple independent voltage converters, each capable of providing specific voltage outputs. By selectively activating individual converters or combinations thereof, the system can adapt to different power requirements while maintaining stable and reliable power delivery for each server type.
3Productivity
If multiple voltage converters are deployed in parallel in a power support unit, then the power supply efficiency improves through dynamic selection, but the device complexity increases
Solution Approach 1:
The control unit dynamically selects and activates only the necessary voltage converters based on the server's target power supply power. This dynamic control optimizes power supply efficiency by avoiding unnecessary conversions and reducing power loss, while the automated selection process manages the complexity of having multiple converters in parallel.
