Innovation Solution
Implementing a system that uses structured, filtered light sources and digital cameras to capture and compare gemstone images with machine learning, enhancing image analysis through optical filters that enhance facet junctions and inclusions, and enabling remote verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional laser engraving is used to mark gemstones, then identification and tracking are enabled, but the inscriptions are vulnerable to counterfeiting
Solution Approach 1:
The patent applies color changes by using optical filters that cause different portions of the gemstone to appear in different colors or brightness levels under structured light illumination. This creates a visually distinctive, multi-color appearance for genuine inscriptions that is difficult to replicate with traditional monochrome laser engraving, thereby reducing counterfeiting risk while maintaining reliable identification.
2Measurement precision
If manual verification processes are used for gemstone inscriptions, then detailed inspection is possible, but the process is time-consuming and expensive
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated optical system that uses structured light sources and digital cameras to capture images of gemstone inscriptions. The system automatically analyzes these images to verify authenticity, eliminating the need for time-consuming manual examination while maintaining or improving inspection accuracy through consistent, repeatable measurements.
Solution Approach 2:
The patent creates digital copies (images) of the gemstone inscriptions under structured light illumination. These digital copies can be stored, transmitted, and analyzed automatically without requiring physical handling or manual inspection of the actual gemstone, significantly reducing verification time while preserving detailed inspection capabilities through high-resolution imaging and image processing.
3Reliability
If complex verification systems are implemented to prevent counterfeiting, then security is improved, but device complexity increases
Solution Approach 1:
The patent achieves enhanced counterfeit prevention through color changes produced by optical filters rather than through mechanically complex systems. The structured light source combined with filters creates distinctive multi-color patterns on genuine inscriptions that are simple to generate but difficult to replicate, providing high security with relatively simple device architecture.
