Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple redundant power supplies are mounted on a single bus to ensure uninterrupted power supply, then power supply reliability is improved, but investment cost increases
Solution Approach 1:
The patent merges multiple high-voltage direct current power supply buses with different voltages into a unified system through DC/DC conversion modules. These modules enable power sharing and mutual backup between buses that previously required separate redundant systems, reducing the total number of power supplies needed while maintaining reliability.
Solution Approach 2:
The DC/DC conversion modules provide universal compatibility between different voltage-level power supply buses, allowing a single power supply to serve multiple voltage requirements. This multi-functionality eliminates the need for individualized power supply circuits for each voltage level, reducing investment while ensuring uninterrupted power supply.
2Adaptability or versatility
If different matching power supply circuits are built for different data load devices with different voltage requirements, then power supply adaptability is improved, but device complexity increases
Solution Approach 1:
The patent introduces DC/DC conversion modules as intermediary devices between different voltage-level power supply buses and data load devices. These modules act as mediators that handle voltage conversion and matching, allowing power supply buses to maintain standardized voltages while adapting to various device requirements, thereby reducing overall system complexity.
Solution Approach 2:
The system dynamically changes voltage parameters through DC/DC conversion modules that can convert between different high-voltage direct current levels (e.g., 240V, 336V, 400V). This parameter flexibility allows a standardized power supply architecture to serve multiple voltage requirements without building separate circuits for each device.
3Manufacturing precision
If individualized power supply circuits are constructed according to specific voltage requirements, then power supply precision is improved, but operation and maintenance difficulty increases
Solution Approach 1:
The patent segments the power supply system into standardized high-voltage direct current buses with fixed voltage levels and modular DC/DC conversion units. This segmentation allows each component to be designed and manufactured with high precision for its specific function, while the modular structure simplifies operation and maintenance compared to integrated individualized circuits.
Solution Approach 2:
The system employs dynamic voltage conversion through controllable DC/DC modules that can adaptively adjust output voltages based on real-time requirements. This dynamic capability maintains precise power supply for different devices while centralizing control functions, thereby reducing operation and maintenance complexity compared to static individualized circuits.
