Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment method is used for double-layer coating die, then flexibility in adjustment is maintained, but debugging effectiveness and efficiency deteriorate due to high skill requirements
Solution Approach 1:
The patent replaces the manual mechanical adjustment system with an automated control system that uses sensors to detect slurry parameters and automatically adjusts coating die parameters through electronic control, eliminating the need for manual intervention and reducing skill requirements
Solution Approach 2:
The system enables self-adjustment by automatically detecting slurry parameters and adjusting coating die parameters without human intervention, allowing the system to service itself and improve debugging efficiency
2Device complexity
If manual adjustment method is used for double-layer coating die, then system complexity is kept simple, but debugging effectiveness deteriorates
Solution Approach 1:
The patent replaces simple manual adjustment with an automated control system that uses sensors and electronic control to improve reliability and debugging effectiveness, accepting increased system complexity as necessary for achieving consistent, high-quality results
3Productivity
If automated adjustment is implemented, then debugging effectiveness and efficiency are improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback control system where sensors detect slurry parameters and automatically adjust coating die parameters based on detected values, creating a closed-loop system that improves coating efficiency while managing complexity through intelligent control
Solution Approach 2:
The automated control system serves multiple functions including parameter detection, analysis, and adjustment, consolidating multiple operations into a single integrated system that improves efficiency without proportionally increasing complexity
