Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple detectors are used to accurately detect workpiece and grinding wheel positions, then measurement precision and manufacturing precision are improved, but device complexity increases
Solution Approach 1:
The detection system is segmented into multiple specialized detectors: a first detector for detecting workpiece position in the cutting direction, a second detector for detecting workpiece position in feeding directions, a third detector for detecting grinding wheel position in the cutting direction, and a fourth detector for detecting grinding wheel position in the feeding direction. Each detector is responsible for specific measurement tasks, enabling high-precision detection while maintaining clear functional separation and reducing overall system complexity.
2Extent of automation
If automatic calculation of grinding range is implemented using detected position information, then extent of automation is improved and operator burden is reduced, but device complexity increases
Solution Approach 1:
The control device performs preliminary calculations of the grinding range before actual grinding operations begin. By using position information detected by the four detectors, the control device automatically determines the optimal grinding range, enabling fully automatic grinding operations without requiring operator intervention for range setting, thereby achieving high automation while keeping the control logic straightforward.
3Productivity
If teaching operations are eliminated in favor of automatic detection and calculation, then productivity is improved and loss of time is reduced, but measurement precision requirements increase
Solution Approach 1:
The grinding apparatus performs self-service by automatically detecting workpiece and grinding wheel positions using the four detectors and autonomously calculating the grinding range without requiring external operator teaching operations. The control device uses the detected position information to automatically determine grinding parameters, enabling fully automatic operation that eliminates time-consuming teaching procedures while maintaining high measurement precision through the coordinated use of multiple detectors.
