Engineering Contradiction Analysis
1Measurement precision
If conventional spectroscopic analysis devices are used, then measurement accuracy is maintained, but device cost and complexity increase significantly
Solution Approach 1:
The patent uses an image sensor to capture optical signals instead of requiring complex spectroscopic detection systems. By converting optical information into image data that can be processed computationally, the system replicates the functionality of expensive spectroscopic devices using more affordable imaging components combined with quantum dot wavelength filtering.
Solution Approach 2:
The patent replaces traditional mechanical spectroscopic analysis systems with an optical system using quantum dots and image sensors. Instead of using complex mechanical spectrometers or expensive detectors, the system uses wavelength-selective quantum dot filters combined with standard image sensors and computational algorithms to achieve component analysis.
2Measurement precision
If conventional spectroscopic analysis methods are used, then component analysis capability is achieved, but analysis time increases significantly
Solution Approach 1:
The patent employs sequential illumination with different wavelengths corresponding to different quantum dot layers, capturing multiple images in rapid succession. This periodic wavelength switching allows the system to collect spectral information across multiple wavelength bands quickly, enabling real-time or near-real-time component analysis without the time-consuming procedures of conventional spectroscopy.
Solution Approach 2:
The system continuously captures images while sequentially activating different quantum dot layers, maintaining uninterrupted data collection. The image sensor continuously records optical signals as wavelengths are switched, allowing for rapid accumulation of spectral information without the start-stop nature of traditional spectroscopic methods.

Solution Approach 1:
The system incorporates automated image processing and component identification algorithms that perform spectral analysis without requiring expert intervention. The control unit automatically processes captured images, identifies components based on their spectral signatures, and outputs results, making the system self-sufficient and easy to operate for non-experts while maintaining measurement accuracy.
Solution Approach 2:
The patent introduces computational algorithms as an intermediary between the image sensor and the user. These algorithms automatically interpret the raw image data, perform spectral unmixing, identify components, and present results in an easily understandable format, bridging the gap between complex optical measurements and user-friendly output without requiring expert knowledge.
