Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sensing board is provided on the cooling liquid flow path in a general battery cell module, then battery cell monitoring and safety functions are improved, but the flow of cooling liquid through the cooling channel is hindered and cooling efficiency is degraded
Solution Approach 1:
The cartridge is divided into multiple sections with cooling channels in specific regions, separating the sensing board area from the primary cooling flow paths. This segmentation allows the sensing board to perform its monitoring function while cooling channels maintain unobstructed flow in dedicated zones between battery cells.
Solution Approach 2:
Cooling channels are selectively disposed in specific local regions between battery cells where sensing boards are not present, creating zones of optimized cooling flow. The cartridge structure provides different functional qualities in different areas: monitoring functions where sensing boards are located and efficient cooling where channels are positioned.
2Temperature
If cooling channels are disposed between battery cells for direct cooling, then cooling performance is improved, but the presence of sensing boards on the flow path hinders cooling liquid flow
Solution Approach 1:
The cooling system utilizes the three-dimensional space within the cartridge by positioning cooling channels in the vertical and lateral dimensions between battery cells, rather than only in a single planar layer. This multi-dimensional arrangement allows cooling channels to bypass sensing board locations while maintaining effective thermal contact with battery cell surfaces.
Solution Approach 2:
The cartridge structure acts as an intermediary component that mediates between the sensing board and cooling channels. It provides a framework that accommodates sensing boards in certain areas while creating dedicated cooling channels in other areas, allowing both functions to coexist without direct interference.
3Stability of the object's composition
If protrusion structures are added to the cartridge for aligning and fixing battery cells, then structural stability is improved, but device complexity increases
Solution Approach 1:
The protrusion structures are merged with the cartridge body as integrated features rather than separate components. These protrusions are formed directly on the cartridge inner surface, combining the alignment and fixing functions with the existing cartridge structure, thereby providing stability without significantly increasing overall device complexity.
Solution Approach 2:
The protrusion structures provide self-aligning and self-fixing capabilities for battery cells within the cartridge. As battery cells are inserted, the protrusions automatically guide them into the correct position and secure them in place, eliminating the need for additional complex alignment mechanisms or assembly steps.
