Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If personalized information content is incorporated into optical images using traditional methods, then content uniqueness is achieved, but implementation speed and reliability deteriorate
Solution Approach 1:
The patent applies parameter changes by transforming the optical image into the frequency domain using Fourier transform. This changes the representation parameters of the image, allowing information to be embedded in the frequency spectrum rather than spatial domain, which enables both rapid processing and reliable protection against traditional image analysis attacks.
Solution Approach 2:
The patent introduces an intermediary mechanism by using watermarks or codes as mediators between the original information content and the optical image. These watermarks serve as reliable identifiers that can be rapidly detected and verified, ensuring content protection without requiring complex analysis of the entire image.
2Reliability
If error-resistant encoding schemes are used to protect information content, then reliability improves, but implementation complexity increases
Solution Approach 1:
The patent replaces complex mechanical or manual encoding verification systems with automated digital signal processing. By using Fourier transform and digital watermarking techniques, the system automatically detects and verifies embedded information, reducing implementation complexity while maintaining high reliability through mathematical error-resistant properties.
3Measurement precision
If discrete Fourier transforms are used to encode information in optical images, then precision and speed improve, but processing requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-computing and storing the Fourier transform basis functions and watermark patterns. This allows the actual encoding and decoding operations to be performed rapidly by simply comparing against pre-computed references, reducing real-time computational energy consumption while maintaining high detection precision.
