Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate components are used to install cooling channels in battery modules, then cooling function is achieved, but process costs increase and assembly complexity increases
Solution Approach 1:
The patent integrates the cooling channel directly into the battery module case structure, merging the case and cooling channel into a single integrated component. This eliminates the need for separate cooling channel components and their installation processes, thereby reducing both process costs and assembly complexity while maintaining the cooling function.
2Productivity
If separate components are used to install cooling channels in battery modules, then cooling function is achieved, but assembly processes increase
Solution Approach 1:
By integrating the cooling channel into the case structure, the patent reduces the number of assembly steps. The cooling channel is formed as part of the case during case manufacturing, eliminating separate installation processes and reducing assembly time, thereby improving productivity.
3Device complexity
If integrated end plate with coolant flow tube is used, then assembly processes are simplified, but manufacturing complexity of end plate increases
Solution Approach 1:
The patent employs integral molding technology to manufacture the end plate with integrated coolant flow tubes. This manufacturing approach, while complex in process, allows for the production of integrated structures as a single component, simplifying assembly and reducing the number of parts without requiring multiple separate manufacturing and assembly operations.
