Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cooling water pumps are used to satisfy performance requirements, then the cooling performance is improved, but the device complexity and number of parts increase
Solution Approach 1:
The patent merges multiple pump functions into a single screw pump by providing multiple outlets on one housing. This allows one pump to perform the work of multiple pumps while reducing part count and system complexity. The screw pump includes a first outlet for the first cooling line and a second outlet for the second cooling line, enabling single-pump multi-circuit operation.
Solution Approach 2:
The screw pump is designed as a multi-functional device that can serve multiple cooling circuits simultaneously. By incorporating multiple outlets with different flow rates, the single pump can satisfy the cooling requirements of different components (battery, electronic components) with varying cooling demands, replacing the need for dedicated pumps for each circuit.
2Adaptability or versatility
If multiple cooling water pumps and long pipes are used to connect parts, then the cooling coverage is improved, but the pressure drop increases and system efficiency decreases
Solution Approach 1:
The patent combines multiple outlet ports on a single pump housing, allowing direct connection to different cooling circuits without requiring long connecting pipes. The first outlet connects to the battery cooling line and the second outlet connects to the electronic component cooling line, reducing pipe length and minimizing pressure drop while maintaining comprehensive cooling coverage.
3Reliability
If multiple cooling water pumps are used, then the cooling capacity is improved, but the assembly process becomes complicated and difficult
Solution Approach 1:
The patent integrates multiple outlet ports and connection interfaces into a single pump assembly, reducing the number of discrete components that need to be assembled. The screw pump is provided as one integrated unit with multiple outlets, simplifying the assembly process compared to installing and connecting multiple separate pumps to the cooling system.
