Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current asset verification systems, such as the Sarine TruMatch diamond verification system, are limited in that they only scan tags on the surface of gems and require additional user scanning for QR/bar code output, lacking comprehensive and efficient methods for verifying assets internally.
Innovation Solution
An asset verification system comprising a reader with a holder, light source, magnifying optics, and a multi-function hardware device for reading laser-etched tags within the asset, utilizing a distributed ledger for data storage and processing, enabling efficient and accurate identification, registration, and tracking of assets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surface scanning is used for tag reading, then the system complexity is reduced, but the verification completeness and security are insufficient
Solution Approach 1:
The patent transitions from surface-level scanning to internal volumetric reading by embedding tags within the asset body. This dimensional shift from 2D surface to 3D internal space enables more secure and complete verification, as the embedded tags cannot be easily replicated or tampered with compared to surface tags.
Solution Approach 2:
The tag is nested within the body of the asset rather than placed on the surface. This nesting approach embeds the verification element inside the asset structure, providing enhanced security and verification completeness while maintaining system feasibility through integrated design.
2Productivity
If manual QR/bar code scanning is required, then the device complexity is reduced, but the productivity and user experience deteriorate
Solution Approach 1:
The system automatically reads the embedded tag when the asset is placed in the holder, eliminating the need for manual scanning operations. The verification process occurs autonomously through the integrated reader and processing system, significantly improving productivity and user experience.
Solution Approach 2:
The patent combines the holder, reader, optics, and processing systems into an integrated verification unit. This merging of functions allows automatic tag reading and verification without requiring separate manual scanning steps, enhancing efficiency while consolidating system components.
3Measurement precision
If high magnification optics are used for internal tag viewing, then the measurement precision is improved, but the device complexity and size increase
Solution Approach 1:
The patent replaces complex mechanical magnification systems with optical approaches using transparent materials and focused light sources. This substitution achieves high precision tag reading through optical properties rather than mechanical magnification, reducing overall system complexity.
Solution Approach 2:
The system utilizes changes in light parameters (wavelength, intensity, focus) to achieve high precision reading of internal tags. By adjusting optical parameters rather than relying solely on magnification, the system achieves accurate tag detection with a more compact and manageable optical configuration.
