Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional gemstone certification processes are used, then authentication can be performed, but the process is time-consuming and vulnerable to counterfeit inscriptions
Solution Approach 1:
The patent replaces manual inspection methods with automated optical imaging and machine learning algorithms. A standardized lighting system with specific illuminants (D65, A, F2) and a digital camera capture inscriptions and facet patterns, which are then analyzed by AI models to authenticate gemstones, eliminating time-consuming manual verification while improving reliability through consistent, objective analysis
Solution Approach 2:
The system performs preliminary capture of inscription images and facet patterns during the grading process itself, storing these images in a database. When authentication is needed later, the pre-captured images are retrieved and compared using machine learning, eliminating the need for repeated physical inspection and significantly reducing verification time
2Reliability
If manual inspection methods are used, then gemstone authentication can be performed, but the process is vulnerable to counterfeit inscriptions
Solution Approach 1:
The patent replaces subjective manual inspection with automated optical imaging and machine learning analysis. The system captures high-resolution images of inscriptions and facet patterns using standardized lighting and camera equipment, then uses AI algorithms to objectively analyze and compare these features, making counterfeit detection more reliable while removing human error and bias from the process
Solution Approach 2:
The system creates digital copies of gemstone inscriptions and facet patterns through standardized imaging. These digital images are stored in a database and used for comparison and authentication. The machine learning models analyze these copies to verify authenticity, allowing multiple verifications without physical handling of the original gemstone
3Measurement precision
If standardized lighting and filtering are applied, then image clarity is improved, but the device complexity increases
Solution Approach 1:
The patent applies standardized lighting parameters (specific illuminants D65, A, F2 with defined color temperatures and spectral power distributions) to improve image consistency and clarity. By controlling lighting parameters and using filters to achieve standardized illumination, the system produces comparable images across different gemstones and viewing conditions, enhancing measurement precision while maintaining systematic control over the added complexity
