Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple independent cooling circuits are used for different heating components, then each component can be cooled independently, but the system complexity and number of components increase
Solution Approach 1:
The patent merges multiple independent cooling circuits into a single integrated cooling system with one pump station. The pump station has multiple outlets that can independently supply cooling medium to different heating components (generator, converter, transformer, shaft system), eliminating the need for separate pump stations while maintaining independent cooling capability for each component.
2Adaptability or versatility
If multiple pump stations are used for different cooling circuits, then each circuit can operate independently, but the number of components and system complexity increase
Solution Approach 1:
The pump station is designed as a multi-functional device with a single pump body that has multiple outlets, allowing it to serve multiple cooling circuits simultaneously. Each outlet can independently supply cooling medium to different heating components, enabling the single pump station to perform the functions of multiple separate pump stations.
3Reliability
If complex line configurations are used to cool multiple components, then all components can be cooled, but the line layout becomes cumbersome and prone to failures
Solution Approach 1:
The cooling system is segmented into multiple independent cooling circuits, each serving a specific heating component. The pump station has separate outlets and dedicated piping for each circuit (first cooling circuit for generator, second for converter, third for transformer, fourth for shaft system), allowing simplified line layouts while maintaining comprehensive cooling coverage.
