Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling devices are arranged in battery housing parts, then cooling performance is improved, but manufacturing complexity increases and dynamic properties deteriorate
Solution Approach 1:
The patent merges the cooling function directly into the battery housing structure by forming cooling channels within the housing itself through integral forming or injection molding. This integration eliminates the need for separate cooling devices and assemblies, thereby improving cooling performance while reducing manufacturing complexity. The cooling channels are created as inherent features of the housing geometry rather than as add-on components.
Solution Approach 2:
The battery housing is designed to serve multiple functions simultaneously: it provides structural support, protection for battery cells, and integrated cooling. By incorporating cooling channels directly into the housing structure, the same component performs both mechanical and thermal management functions, reducing the overall number of parts and simplifying manufacturing while maintaining effective cooling performance.
2Temperature
If cooling devices are arranged in battery housing parts, then cooling performance is improved, but dynamic properties deteriorate
Solution Approach 1:
By integrating cooling channels directly into the battery housing structure through integral forming, the patent creates a unified component that maintains consistent mechanical properties throughout. This merging eliminates interfaces between separate cooling devices and housing, thereby preserving dynamic properties and structural integrity while achieving effective cooling performance.
3Temperature
If complex manufacturing processes are used, then cooling performance is improved, but production cost and complexity increase
Solution Approach 1:
The cooling channels are formed during the initial integral forming or injection molding process of the battery housing, rather than requiring subsequent assembly steps. This preliminary action incorporates the cooling function into the base manufacturing process, eliminating the need for complex post-processing or separate assembly operations, thereby maintaining effective cooling performance while simplifying production.
