Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a large number of unit battery cells are coupled into a battery module, then the power output is improved, but the complexity of electrical integration and signal detection increases
Solution Approach 1:
The connection board is divided into multiple connection board modules, each handling a specific group of battery cells. This segmentation allows the system to scale to larger numbers of cells without proportionally increasing overall complexity, as each module can be independently managed and assembled.
Solution Approach 2:
The connection board modules are designed with universal interfaces and standardized structures that can accommodate different numbers and configurations of battery cells. The same basic module design can be replicated and combined to handle various power requirements, reducing the need for custom designs for different cell counts.
2Power
If a large number of unit battery cells are coupled into a battery module, then the power output is improved, but the assembly process becomes more complex
Solution Approach 1:
The connection board is divided into multiple connection board modules, each handling a specific group of battery cells. This segmentation allows the system to scale to larger numbers of cells without proportionally increasing overall complexity, as each module can be independently managed and assembled.
Solution Approach 2:
The connection board modules are pre-assembled with circuit boards and connection members before being integrated into the battery module. This preliminary assembly simplifies the final integration process, as pre-tested modules can be quickly installed without complex on-site wiring and connection procedures.
3Ease of manufacture
If the number of battery modules is reduced by coupling more unit cells per module, then space and costs are saved, but the electrical integration difficulty increases
Solution Approach 1:
The connection board modules are designed with universal interfaces and standardized structures that can accommodate different numbers and configurations of battery cells. The same basic module design can be replicated and combined to handle various power requirements, reducing the need for custom designs for different cell counts.
Solution Approach 2:
The system allows for parameter changes in the number and configuration of connection board modules to match different battery cell arrangements. By adjusting modular parameters rather than redesigning the entire connection system, the patent achieves adaptability to various cell counts while maintaining integration simplicity.
4Power
If a large number of detection signals need to be measured, then the power output is improved, but the wiring complexity increases
Solution Approach 1:
Multiple detection signals from different battery cells are merged and routed through the circuit boards integrated with the connection board modules. This consolidation reduces the number of separate wiring paths needed, as the modular structure provides organized signal collection and transmission routes.
Solution Approach 2:
The circuit boards serve as intermediaries between the battery cells and the detection system. They collect, process, and transmit detection signals in an organized manner, reducing the complexity of direct wiring between numerous cells and the central detection system.
