Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If multiple cooling plates and heat pipes are used to cool battery cells, then heat dissipation capability is improved, but device complexity increases
Solution Approach 1:
The patent combines the cooling fluid distributor and housing into a single integrated component. The housing serves dual functions as both structural enclosure and cooling fluid distribution system, eliminating the need for separate cooling plates and heat pipes while maintaining effective heat dissipation capability
Solution Approach 2:
The housing is designed to perform multiple functions simultaneously: it provides mechanical protection for battery cells, serves as a structural support element, and acts as a cooling fluid distributor. This multi-functionality reduces the overall number of components needed in the battery assembly
2Volume of stationary object
If battery cells are arranged at small distances to minimize housing volume, then volume efficiency is improved, but cooling fluid flow distribution deteriorates
Solution Approach 1:
The housing is divided into multiple cooling channels with strategically placed openings that segment the cooling fluid flow. This segmentation ensures that cooling fluid is distributed evenly to multiple battery cells simultaneously, maintaining effective cooling even when cells are closely arranged
Solution Approach 2:
The housing features locally optimized cooling openings positioned at specific locations to target individual battery cells or groups. This local quality approach ensures uniform cooling distribution across all cells despite their compact arrangement, addressing specific cooling needs in different regions of the housing
3Reliability
If additional components like screws are used to assemble housing parts, then assembly reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The cooling fluid distributor and housing are merged into a single injection-molded component, eliminating the need for separate parts and assembly operations. This integration maintains sealing reliability while significantly simplifying the manufacturing process and reducing the number of fastening components required
4Quantity of substance
If cooling fluid distributor cross-section is large, then cooling fluid flow capability is improved, but housing volume increases
Solution Approach 1:
The cooling fluid distributor utilizes the three-dimensional space between the housing inner wall and battery cells effectively. By creating a distributed network of cooling channels and openings throughout the housing structure, the system achieves high cooling fluid flow capability without requiring a large cross-sectional area, thus maintaining compact housing volume
