Engineering Contradiction Analysis
1Reliability
If synchronization error detection is implemented during grinding, then abnormality detection capability is improved, but system complexity increases
Solution Approach 1:
The system continuously monitors synchronization errors between the workpiece and grinding tool during the grinding process, feeding this information back to the control unit. The control unit compares the synchronization error against predetermined thresholds and automatically determines whether an abnormality has occurred, enabling real-time quality control without manual intervention
Solution Approach 2:
The patent replaces complex mechanical measurement systems with a control unit that electronically monitors synchronization errors. By using phase difference detection and frequency analysis through the control unit, the system achieves abnormality detection without requiring additional mechanical measurement apparatus, thus improving reliability while minimizing the increase in system complexity
2Manufacturing precision
If phase difference data and frequency analysis are used for abnormality determination, then manufacturing precision is improved, but measurement complexity increases
Solution Approach 1:
The patent replaces complex mechanical measurement systems with a control unit that electronically monitors synchronization errors. By using phase difference detection and frequency analysis through the control unit, the system achieves abnormality detection without requiring additional mechanical measurement apparatus, thus improving reliability while minimizing the increase in system complexity
Solution Approach 2:
The control unit automatically performs frequency analysis on the synchronization error data and compares it against predetermined thresholds to determine abnormalities. This self-service capability eliminates the need for manual measurement and analysis, improving manufacturing precision while keeping the measurement process simple and automated
