Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent power sources are used for servers with different voltage requirements, then each server can receive the required voltage, but the space occupied by power supplies increases significantly
Solution Approach 1:
The patent implements a single power supply unit that can output multiple different voltages (e.g., 12V, 5V, 3.3V) simultaneously through multiple output terminals. This multi-functional power supply replaces multiple independent power sources, providing voltage compatibility for different server types while significantly reducing the space occupied by power supply equipment.
2Device complexity
If conventional power supplies are used without monitoring functions, then the system is simpler, but layout errors and voltage mismatches cannot be detected
Solution Approach 1:
The patent incorporates monitoring circuits that continuously detect the voltage and current at each output terminal of the power supply. These monitoring functions provide real-time feedback about the power distribution status, enabling the system to detect layout errors and voltage mismatches automatically while maintaining relatively simple system architecture.
3Adaptability or versatility
If numerous power supplies are deployed to serve many servers, then voltage requirements are met, but automatic power management becomes difficult
Solution Approach 1:
The monitoring circuits provide real-time data on voltage and current at each output terminal, enabling the controller to automatically manage power distribution. The system can detect when servers are connected or disconnected, identify voltage mismatches, and adjust power allocation automatically, achieving high extent of automation despite the complex power distribution requirements.
