Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the liquid outlet nozzle is manually butted to the liquid injection port, then the operation is simple, but the butting accuracy is low affecting injection success rate
Solution Approach 1:
The patent replaces manual mechanical butting operations with an automatic positioning system that uses visual recognition (cameras) and automated adjustment mechanisms to achieve precise alignment between the liquid outlet nozzle and liquid injection port, eliminating manual operation while improving accuracy
Solution Approach 2:
The system performs self-positioning and self-adjustment through automated detection and correction mechanisms, where the device automatically identifies misalignment and adjusts its components to achieve accurate butting without requiring external manual intervention
2Manufacturing precision
If the battery position is not adjusted, then the operation is fast, but the liquid injection accuracy is poor causing potential damage
Solution Approach 1:
The system performs preliminary detection and positioning of the battery before the liquid injection operation, using cameras and positioning mechanisms to ensure accurate alignment in advance, which prevents injection errors while maintaining efficient workflow
Solution Approach 2:
The system uses real-time detection and feedback mechanisms where sensors and cameras monitor battery position, and the system automatically adjusts based on detected deviations to ensure accurate injection while maintaining high throughput
3Manufacturing precision
If automatic detection and adjustment mechanism is added, then the butting accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent integrates multiple functions into unified components, where the positioning system serves both detection and adjustment purposes, and the control system manages multiple operations (detection, positioning, injection) through a single integrated controller, reducing overall system complexity despite added capabilities
