Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional stacking processes are used, then battery cells can be stacked, but different polarity combination modes cannot be arranged according to production requirements
Solution Approach 1:
The system segments battery cells into different conveying members based on polarity groups, allowing independent handling and arrangement of cells with different polarities. This segmentation enables flexible combination modes while maintaining efficient automated processing.
Solution Approach 2:
The gripping mechanism is designed to be dynamically adjustable, capable of adapting its gripping pattern and arrangement mode according to different polarity combination requirements. This dynamic capability allows the system to switch between different stacking patterns without manual reconfiguration.
2Adaptability or versatility
If manual arrangement is used for different polarity combinations, then flexibility is achieved, but production efficiency decreases
Solution Approach 1:
The system implements self-service through automated gripping mechanisms that automatically identify and arrange battery cells according to preset polarity combinations. The mechanism autonomously adjusts its operation mode based on the required configuration, eliminating the need for manual intervention while maintaining flexibility.
Solution Approach 2:
The system changes operational parameters of the gripping mechanism to adapt to different polarity combination modes. By adjusting gripping force, movement speed, and arrangement patterns, the system achieves versatile configuration capabilities while maintaining high-speed automated operation.
3Manufacturing precision
If multiple conveying members are used for different polarities, then polarity combination precision is improved, but device complexity increases
Solution Approach 1:
The gripping mechanism is designed as a universal device capable of handling battery cells from multiple conveying members with different polarities. This multi-functional design allows a single mechanism to perform arrangement tasks for various polarity combinations, reducing overall system complexity while maintaining precision.
Solution Approach 2:
The gripping mechanism acts as an intermediary between multiple conveying members and the stacking position. It receives cells from different polarity-specific conveying members and orchestrates their precise arrangement according to the required combination mode, simplifying the coordination between multiple components.
