Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-plate structure or upper-lower housing structure is adopted for battery accommodating assembly, then battery protection is improved, but combination mode flexibility deteriorates and redesign is required for different battery configurations
Solution Approach 1:
The battery accommodating assembly is segmented into multiple independent separator components, each capable of accommodating batteries. These separators can be detached and reconfigured to create different combination modes (series, parallel, or series-parallel connections), enabling flexibility without requiring complete redesign of the housing structure.
Solution Approach 2:
The battery accommodating assembly transitions from a fixed rigid structure to a dynamic reconfigurable structure. The detachable separators allow the system to adapt its configuration dynamically based on different battery combinations and service requirements, maintaining protection while enabling flexibility.
2Reliability
If multi-plate structure or upper-lower housing structure is adopted, then battery protection is improved, but production automation compatibility deteriorates and cost increases
Solution Approach 1:
By dividing the battery accommodating assembly into modular separator units with standardized connection interfaces, the system enables automated assembly and disassembly operations. Each separator can be independently manufactured and assembled, facilitating production automation while maintaining protective functions.
Solution Approach 2:
The standardized separator design serves multiple functions: battery accommodation, protection, and easy assembly/disassembly. This universal modular structure can be used across different battery configurations and production lines, improving automation compatibility without sacrificing protection.
3Ease of manufacture
If traditional signal collection and power connection methods are used, then assembly is simple, but wire shaking and insulation failures occur reducing safety
Solution Approach 1:
The signal collection assembly and power connection member are merged into an integrated unit. This combination ensures that signal lines and power connections are arranged together in a structured manner, preventing wire shaking and insulation failures while maintaining assembly simplicity through the unified design.
Solution Approach 2:
The integrated signal collection assembly acts as an intermediary structure that organizes and protects both signal lines and power connections. This mediator component prevents direct contact and potential short circuits between wires while maintaining proper electrical connections, thereby improving safety without complicating assembly.
