Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If noninvasive hyperspectral and multi-spectral diagnostic characterization techniques are used, then measurement precision and reliability are improved, but device complexity increases
Solution Approach 1:
The system segments the electromagnetic spectrum into multiple discrete spectral ranges (e.g., visible, infrared, ultraviolet) and captures images in each range separately using specialized sensors. This segmentation allows precise characterization of different material properties at different wavelengths while managing system complexity through modular sensor arrays and processed imaging approaches
Solution Approach 2:
The patent introduces computational algorithms and data processing intermediaries that transform complex multi-spectral raw data into simplified diagnostic characteristics and quantitative metrics. These intermediaries process the complex spectral information to extract meaningful authentication features, reducing the burden on final decision-making while maintaining high measurement precision
2Loss of information
If multiple electromagnetic spectrums are analyzed, then information completeness is improved, but data processing complexity increases
Solution Approach 1:
The system extracts specific diagnostic characteristics from the comprehensive multi-spectral data set, isolating only the most relevant features for authentication purposes. By taking out and focusing on key spectral signatures and material-specific characteristics, the system maintains complete information availability while simplifying the actual analysis to essential authentication-critical data points
Solution Approach 2:
The patent transforms multi-spectral image data into different parameter representations, such as spectral indices, material composition estimates, and quantitative chemical characteristics. These parameter changes convert complex spectral distributions into manageable numerical metrics that are easier to process and compare for authentication decisions
