Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security measures are used for computer systems and networks, then implementation is straightforward, but security is inadequate particularly as systems become more complex
Solution Approach 1:
The patent replaces traditional electronic/data-based security measures with an optical security system using volume holograms. The holographic identifiers store security data in a physical optical medium that is resistant to digital attacks, data breaches, and electromagnetic interference, thereby improving security reliability while avoiding the complexities of sophisticated cyber security infrastructure
Solution Approach 2:
The patent uses volume holograms embedded in optical substrates as a composite security medium. The holographic structure combines multiple layers and optical properties to create a tamper-resistant identifier that integrates physical security with data storage, providing robust security without requiring complex electronic security systems
2Reliability
If volume holograms are used to store unique identifiers, then tampering resistance and data security are improved, but reading and data transfer require specialized equipment
Solution Approach 1:
The patent uses optical copying principles where a laser reads the volume hologram and projects the stored identifier onto a camera sensor or display medium. This allows the secure holographic data to be optically copied and transferred to digital formats or displayed for verification, enabling data retrieval with relatively simple optical equipment rather than complex specialized readers
Solution Approach 2:
The patent introduces an optical projection intermediary between the volume hologram and the detection medium. The laser acts as a mediator that illuminates the hologram, and the projected image serves as an intermediary representation that can be captured by standard cameras or displayed, simplifying the reading process while maintaining security
3Quantity of substance
If optical identifiers with volume holograms are used, then data capacity and electromagnetic pulse resistance are improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs parameter changes in the holographic recording process, including varying the laser wavelength, angle of incidence, and exposure parameters to optimize the volume hologram fabrication. By adjusting these parameters, the system achieves high data capacity storage with improved tolerance to manufacturing variations, reducing the stringency of precision requirements while maintaining high information density

AI summary
A system includes a multiplexed optical identifier and a reader for the optical identifier. The multiplexed optical identifier includes an optical substrate, and a plurality of volume holograms in the optical substrate. The reader includes an illumination source and a camera. The illumination source is configured to direct light into the optical identifier to produce an image of a corresponding one of the volume holograms at the camera, and the camera is configured to capture the image, which is stored in a digital format by the system. The multiplexed optical identifier contains more than one code page, wherein each of the code pages is used for a different purpose.
