Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional liquid cooling is used for engine components, then engine cooling is effective, but additional components in electric vehicles cannot be cooled
Solution Approach 1:
The air cooling system is designed to serve multiple cooling purposes: cooling battery modules, electronic components, and potentially other thermal-sensitive components in the electric vehicle. The system uses a single air cooling loop with evaporator coils strategically positioned to cool different components, eliminating the need for separate cooling systems for each component type.
2Ease of operation
If air cooling is used for operators, then operator comfort is improved, but component cooling capability is insufficient
Solution Approach 1:
The air cooling system is segmented into multiple zones with dedicated evaporator coils for different components. The system divides the cooling function into: (1) evaporator coils for cooling battery modules, (2) evaporator coils for cooling electronic components, and (3) air flow paths for operator comfort. This segmentation allows each zone to be optimized independently while using the same air cooling infrastructure.
3Productivity
If cool air is directed through the center of the battery housing, then cooling efficiency is improved, but system complexity increases
Solution Approach 1:
The system merges the cooling functions for battery modules and electronic components into a single integrated air cooling loop. The evaporator coils are positioned to utilize the same cooled air stream, and the return air paths are consolidated. This merging reduces the number of separate cooling circuits needed while maintaining high cooling efficiency through centralized air flow management.
