Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple coolant loops and refrigerant loops are used to connect each component for heat exchange, then heat management capability is improved, but device complexity increases and space occupation increases
Solution Approach 1:
The patent combines multiple coolant loops and refrigerant loops into an integrated heat management apparatus where plate heat exchangers serve multiple functions simultaneously. The plate heat exchangers are configured to handle both cooling and heating operations, and the pipelines are merged to reduce redundancy, thereby maintaining heat management capability while reducing overall system complexity
Solution Approach 2:
The plate heat exchangers are designed as multi-functional components that can perform both cooling and heating operations. The same heat exchanger structure is used across different loops, and the system can switch between cooling mode and heating mode using the same hardware infrastructure, eliminating the need for separate dedicated components for each function
2Reliability
If multiple coolant loops and refrigerant loops are used to connect each component for heat exchange, then heat management capability is improved, but space occupation increases
Solution Approach 1:
The patent merges multiple pipelines into a shared infrastructure where the same physical pipes and heat exchangers serve multiple loops. By combining the coolant and refrigerant loops into an integrated apparatus with shared components, the overall space occupation is reduced while maintaining the necessary heat management capabilities across all components
Solution Approach 2:
The heat management apparatus is designed with nested or stacked plate heat exchangers that maximize space utilization. The compact plate heat exchanger design allows multiple heat exchange surfaces to be nested within a small volume, enabling efficient heat transfer while occupying minimal space in the system
3Reliability
If multi-pipeline connection is used, then heat exchange capability is improved, but heat efficiency decreases
Solution Approach 1:
The patent merges the coolant and refrigerant loops into an integrated system where heat can be directly transferred between the two loops through the plate heat exchangers. This reduces the number of intermediate heat transfer steps and minimizes thermal losses that would occur in separate, disconnected loops, thereby improving overall heat efficiency while maintaining heat exchange capability
4Reliability
If multi-pipeline connection is used, then heat exchange capability is improved, but maintenance difficulty increases
Solution Approach 1:
The patent combines multiple loops into an integrated heat management apparatus with unified pipeline connections and centralized heat exchangers. This consolidation reduces the number of separate connection points and potential leak locations, making the system easier to maintain and repair while preserving the heat exchange capabilities of individual loops
5Reliability
If multi-pipeline connection is used, then heat exchange capability is improved, but overhaul area increases
Solution Approach 1:
The patent merges multiple pipelines and heat exchangers into a compact integrated apparatus, significantly reducing the physical footprint and overhaul area required. By consolidating components and using shared infrastructure, the system maintains full heat exchange capability across all loops while occupying minimal space during installation and maintenance operations
