Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual deburring is used, then labor flexibility is maintained, but productivity is low and manufacturing precision is poor
Solution Approach 1:
The patent replaces manual mechanical deburring operations with an automated laser system. The laser beam eliminates the need for physical contact and manual manipulation, dramatically increasing deburring speed while maintaining precision. The automated positioning system guided by image processing further enhances productivity by eliminating human fatigue and inconsistency.
Solution Approach 2:
The system performs self-positioning and self-adjustment through image capture and processing. The actual contour is automatically determined from captured images, and the laser positioning is automatically adjusted based on the deviation between actual and target contours, eliminating the need for constant manual intervention and calibration.
2Manufacturing precision
If manual deburring is used, then equipment cost is low, but manufacturing precision and uniformity deteriorate
Solution Approach 1:
The system captures images of the component, determines the actual contour, compares it with the target contour, and automatically adjusts the laser positioning based on the deviation. This closed-loop feedback mechanism ensures high manufacturing precision by continuously correcting positioning errors and maintaining consistent edge quality throughout the deburring process.
Solution Approach 2:
The patent introduces image processing as an intermediate dimension between physical measurement and laser control. By converting physical contour information into digital image data and processing it computationally, the system achieves high precision positioning without complex mechanical measurement devices, simplifying the overall system while maintaining accuracy.
3Object-generated harmful factors
If conventional sawing is used, then manufacturing capability is achieved, but harmful burrs are generated on component edges
Solution Approach 1:
The system specifically targets and removes only the harmful burrs and chips from the component edges using the laser beam. The image processing identifies burrs as protruding elements beyond the target contour, and the laser precisely eliminates these unwanted material additions without affecting the base component, thereby removing the harmful effect while minimizing additional processing.
4Manufacturing precision
If manual deburring with triangular scraper is used, then burrs can be bent and removed, but uneven contact pressure causes imprecise results
Solution Approach 1:
The patent replaces manual mechanical scraping with laser ablation. The laser beam provides uniform energy distribution across the target area, eliminating the uneven contact pressure inherent in manual scraping. This substitution ensures consistent edge quality throughout the component while dramatically reducing the time required for deburring operations.
