Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the size of the radiator is increased, then the cooling performance of the engine coolant is improved, but the motor capacity of the blower increases and the layout of the engine compartment becomes complicated
Solution Approach 1:
The radiator is divided into multiple independent coolant passages (first coolant passage and second coolant passage) that can be independently controlled. The inlet valve unit and outlet valve unit segment the flow paths, allowing selective activation of different passages based on cooling demands, thereby improving cooling performance without increasing the overall radiator size or blower capacity requirements.
Solution Approach 2:
The system employs dynamic control of coolant flow paths through inlet and outlet valve units that can switch between different passages based on coolant temperature and cooling demands. This dynamic adjustment allows the system to optimize cooling performance in real-time without requiring a larger static radiator structure, thus avoiding increased blower capacity and engine compartment complexity.
2Reliability
If the size of the radiator is increased, then the cooling performance of the engine coolant is improved, but the cost and weight increase
Solution Approach 1:
The radiator core is segmented into multiple independent coolant passages that can be independently controlled by inlet and outlet valve units. This segmentation allows the system to activate only the necessary passages based on cooling demands, achieving improved cooling performance without requiring a larger overall radiator structure, thereby avoiding increased weight and cost.
Solution Approach 2:
The system changes the operational parameters of the radiator by dynamically adjusting which coolant passages are active through valve control. Instead of increasing the physical size of the radiator, the system optimizes performance by changing flow distribution parameters, thereby maintaining the same weight and cost while achieving improved cooling performance.
3Reliability
If the size of the radiator is increased, then the cooling performance of the engine coolant is improved, but the motor capacity of the blower increases
Solution Approach 1:
The radiator flow path is segmented into multiple independent passages controlled by inlet and outlet valve units. This segmentation allows the system to distribute coolant flow more efficiently through selective passage activation, improving cooling performance without requiring increased blower capacity, as the existing blower can effectively circulate coolant through the optimized passage configuration.
Solution Approach 2:
The system dynamically adjusts coolant flow distribution through valve control based on real-time cooling demands. This dynamic optimization allows the existing blower capacity to effectively support improved cooling performance by intelligently distributing flow across different passages, rather than requiring a larger blower to handle increased radiator size.
