Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If standard Raman scattering or conventional detection methods are used, then the measurement process is simple, but the detection range and sensitivity are insufficient for trace components
Solution Approach 1:
The patent introduces molecular sensors as intermediary components that contain tags with characteristic Raman spectra. These tags act as mediators between the measurement apparatus and the target components, enabling highly sensitive detection of trace components through their unique spectral fingerprints without requiring direct detection of the trace components themselves.
Solution Approach 2:
The patent utilizes changes in Raman spectral parameters (frequency, intensity, shape) of tags under different measurement conditions to enable sensitive detection. By monitoring parameter changes in the Raman spectra of tags when they interact with target components, the system achieves high detection sensitivity for trace substances.
2Measurement precision
If molecular sensors with tags are designed for specific measurement ranges, then detection sensitivity improves, but the adaptability to different measurement apparatuses decreases
Solution Approach 1:
The patent designs molecular sensors with tags that have characteristic Raman spectra detectable across multiple measurement ranges and techniques (standard Raman scattering, CARS, SRS). This universal design allows the same tag-based sensor to function with different types of Raman measurement apparatuses, providing both high detection accuracy and broad adaptability.
Solution Approach 2:
The patent employs dynamic selection and optimization of tags based on the specific measurement apparatus and conditions being used. The system can adaptively choose appropriate tags from a library whose Raman spectra are optimized for different measurement ranges, enabling the same sensor platform to achieve high detection accuracy across various measurement techniques.
3Adaptability or versatility
If multiple tags are combined to detect multiple components, then the analysis capability increases, but the complexity of sensor design and selection increases
Solution Approach 1:
The patent segments the detection function into separate modular tags, each designed to detect specific target components. By dividing the multi-component analysis task into individual tag responsibilities, the system achieves high versatility in detecting multiple components while managing design complexity through modular, standardized tag units that can be independently optimized and combined.
Solution Approach 2:
The patent utilizes parameter changes in Raman spectral characteristics (frequency position, intensity ratio, spectral shape) of different tags to enable simultaneous detection of multiple components. By assigning distinct spectral parameter signatures to different tags targeting different components, the system achieves multi-component analysis capability while maintaining manageable sensor design through spectral differentiation.
4Measurement precision
If trace components are measured directly without molecular sensors, then the measurement process is straightforward, but the detection limit is insufficient
Solution Approach 1:
The patent introduces tags as intermediary substances that bind to or interact with trace target components and provide enhanced detection signals through their characteristic Raman spectra. This intermediary approach allows detection of trace components at very low concentrations by measuring the spectral signal of the tag rather than the trace component directly, thereby achieving lower detection limits while managing measurement complexity.
