Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment and separate grinding and observation processes are used, then the engineer can observe and adjust the angle during grinding, but the processing efficiency is low and it takes a lot of time
Solution Approach 1:
The patent combines the grinding process and observation process into a single integrated system. The automated positioning system allows the workpiece to be precisely positioned and ground while the imaging system simultaneously captures and analyzes the facet angles, eliminating the need for separate observation steps and significantly improving processing efficiency
Solution Approach 2:
The patent replaces manual mechanical adjustment and visual observation with an automated imaging and analysis system. The camera system captures images of the facets, and the analysis software automatically measures angles and provides feedback, substituting human skill-based operations with automated optical and computational systems
2Manufacturing precision
If a manually adjusted fixing device and magnifying glass are used for continuous grind and observation, then the engineer can adjust the angle, but a highly skilled engineer is required and the process is time-consuming
Solution Approach 1:
The system performs self-measurement and self-correction through automated imaging and analysis. The system automatically captures images of the facets, analyzes the angles using image processing algorithms, and provides feedback for adjustment, eliminating the need for highly skilled engineers to perform manual measurements and adjustments
Solution Approach 2:
The patent implements a closed-loop feedback system where the imaging system continuously monitors the facet angles during grinding, compares them against target values, and provides real-time feedback for automatic adjustment. This ensures high precision grinding without requiring skilled manual operation
3Adaptability or versatility
If traditional grinding devices are used for 57 or 58 facet jewels, then the existing devices can process these standard patterns, but it is impossible to implement grinding of 36 facets at a crown and girdle to achieve a display effect of 9 hearts and 27 arrows
Solution Approach 1:
The patent employs dynamically adjustable positioning mechanisms that can adapt to different facet patterns. The workpiece holder and grinding head can be programmatically repositioned to accommodate various facet configurations, including the complex 36-facet crown and girdle pattern, while maintaining precise angular control through automated systems
Solution Approach 2:
The patent creates a universal grinding system that can process multiple facet patterns (57-facet, 58-facet, 36-facet, and other custom patterns) using the same equipment. The system achieves this through programmable positioning and automated control that can be configured for different jewel types and facet arrangements

AI summary
The present invention provides a jewel grinding system applied to fields of grinding and processing detection. The jewel grinding system includes a base, a placement rack, a loading robot arm, a movable clamping module, a grinding module, a travel monitoring module, a light spot analysis module, and a control module. An angle of a grinding disc can be freely adjusted to meet different grinding requirements. In addition, a designed first transmission mechanism can achieve transmission to the grinding disc that is flexibly adjusted, and the structure is simple and efficient. By providing the travel monitoring module, a grinding effect can be monitored and measured in real time, which is conducive to intelligently adjust operation of the movable clamping module. Therefore, processing of 36 facets at a crown and a girdle can be well achieved, so that a display effect of 9 hearts and 27 arrows is achieved. Symmetric facets can be grinded at the same time by grinding discs that are symmetrically provided, and thus a grinding efficiency and accuracy are improved. A grinding degree of each facet can be visually and intelligently detected by providing the light spot analysis module. Accurate and rapid mounting can be assisted by providing the loading robot arm.
