Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling fins are disposed between pouch-type battery cells, then heat dissipation is achieved, but device complexity and structural inefficiency increase
Solution Approach 1:
The invention extracts and eliminates the separate cooling fins from the battery system structure. Instead of having independent cooling fins between battery cells, the system uses the natural thermal conductivity of the adhesive material itself to transfer heat, thereby removing the unnecessary structural component while maintaining effective heat dissipation.
Solution Approach 2:
The adhesive material serves multiple functions: it provides structural bonding between components and simultaneously acts as a thermal conduction path for heat dissipation. This multi-functionality eliminates the need for separate cooling fins, reducing structural complexity while maintaining effective thermal management.
2Temperature
If separate cooling fins are used between battery cells, then heat transfer is enabled, but manufacturing complexity and assembly difficulty increase
Solution Approach 1:
The invention merges the cooling function with the adhesive bonding function into a single integrated component. The adhesive material is applied directly between battery cells during assembly, combining structural attachment and thermal management in one step, thereby simplifying both manufacturing and assembly processes.
Solution Approach 2:
The adhesive material inherently provides thermal conduction properties without requiring additional cooling fin components. The system uses the existing adhesive layer to self-perform the heat transfer function that would otherwise require separate cooling structures, reducing assembly complexity.
3Temperature
If cooling fins are installed between battery cells, then thermal management is achieved, but space occupation and structural efficiency deteriorate
Solution Approach 1:
The invention removes the separate cooling fin structures that occupy additional space between battery cells. By using the adhesive material's inherent thermal conductivity, the system eliminates the volume-consuming cooling fins while maintaining effective thermal management through the existing adhesive layers.
