Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-plate structure or upper-lower housing structure is used for battery accommodating assembly, then battery protection is improved, but adaptability to different connection modes deteriorates and device complexity increases
Solution Approach 1:
The battery accommodating assembly is divided into multiple detachable separators, each separator being an independent module that can be assembled in different configurations. This segmentation allows the same basic module to be adapted for different connection modes (series, parallel, series-parallel) by simply changing the arrangement and number of separators, without requiring redesign of the entire structure.
Solution Approach 2:
The separators are designed with detachable connections that allow dynamic reconfiguration. The connection structures enable separators to be easily assembled, disassembled, and rearranged to match different battery connection requirements, providing flexibility and adaptability while maintaining protection functionality.
2Reliability
If multi-plate structure or upper-lower housing structure is used for battery accommodating assembly, then battery protection is improved, but manufacturing cost and time increase due to redesign requirements
Solution Approach 1:
Each separator is designed as a universal module that can serve multiple functions and configurations. The same separator design can be used across different battery module configurations by varying the number and arrangement of separators, eliminating the need for custom designs for each connection mode and reducing manufacturing complexity.
Solution Approach 2:
The modular separator design allows individual separators to be independently replaced, maintained, or upgraded without affecting the entire battery assembly. This facilitates easier manufacturing, repair, and maintenance operations, reducing overall manufacturing costs and time.
3Adaptability or versatility
If traditional wire-based power connection and signal transmission is used, then connection flexibility is maintained, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The power connection lines and signal collection lines are merged into a single integrated substrate structure. This consolidation reduces the number of separate components and connections required, simplifying the overall device complexity while maintaining the flexibility to accommodate different battery configurations through the modular separator design.
4Adaptability or versatility
If detachable separators are used for battery accommodating assembly, then adaptability to different connection modes is improved, but structural stability may deteriorate
Solution Approach 1:
The separators are designed with pre-formed connection structures and positioning features that ensure stable and precise assembly. The detachable connection mechanisms are pre-engineered to provide reliable mechanical and electrical connections, maintaining structural stability while enabling reconfiguration for different connection modes.
