Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one water-cooling system is used to control temperature of multiple batteries, then device complexity is reduced, but temperature control precision and heat exchange efficiency deteriorate
Solution Approach 1:
The patent divides the water-cooling system into multiple independent modules, each capable of controlling temperature for specific batteries. This segmentation allows each module to operate independently, achieving precise temperature control for individual batteries while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The patent implements dynamic allocation of water-cooling modules to batteries based on real-time temperature conditions. The system can flexibly connect and disconnect modules from different batteries, enabling adaptive temperature control that responds to varying thermal conditions of individual batteries.
2Stability of the object's composition
If supply water temperature is set to comprehensively consider thermal performance of all batteries, then system stability is improved, but heat exchange efficiency and charging speed deteriorate
Solution Approach 1:
The patent enables dynamic adjustment of water-cooling module allocation based on real-time battery temperature conditions. When batteries require different temperatures, the system dynamically connects or disconnects specific modules from corresponding batteries, allowing each battery to receive optimal cooling without compromising overall system stability.
3Device complexity
If water-cooling system heating capacity is insufficient for low-temperature batteries, then device simplicity is maintained, but battery safety and charging reliability deteriorate
Solution Approach 1:
The patent implements dynamic module allocation where water-cooling modules can be selectively connected to batteries requiring heating or cooling based on real-time temperature conditions. This dynamic capability ensures that batteries at low temperatures receive adequate heating capacity without requiring the entire system to be oversized for maximum heating demands.
