Engineering Contradiction Analysis
1Object-affected harmful factors
If Raman spectroscopy is used for non-invasive blood glucose measurement, then non-invasive testing can be implemented, but the device becomes bulky and cannot be portable
Solution Approach 1:
The patent replaces the complex mechanical Raman spectroscopy system with an optical fluorescence detection system. This substitution maintains the non-invasive advantage while significantly reducing device complexity and improving portability, as fluorescence spectroscopy requires simpler optical components and can be implemented in a compact form factor.
Solution Approach 2:
The patent changes the detection parameter from Raman scattering to fluorescence emission. By using fluorescence spectroscopy instead of Raman spectroscopy, the system achieves non-invasive measurement with reduced device complexity. The fluorescence method allows for portable implementation while maintaining measurement capability through appropriate wavelength selection and detection.
2Object-affected harmful factors
If absorption spectroscopy is used for non-invasive glucose testing, then non-invasive measurement can be achieved, but spectral signals of different components are mixed together making it difficult to perform fine separation
Solution Approach 1:
The patent segments the spectral measurement by selecting specific fluorescence excitation and emission wavelength ranges. Instead of analyzing the entire absorption spectrum where signals are mixed, the system divides the measurement into targeted wavelength bands that selectively capture glucose-related fluorescence signals while minimizing interference from other skin components.
Solution Approach 2:
The patent introduces fluorescence as an intermediary phenomenon between light interaction and glucose detection. By using fluorescence spectroscopy with specific excitation wavelengths, the system converts the complex absorption problem into a selective emission detection problem, where glucose molecules act as fluorescent intermediaries that emit at characteristic wavelengths, enabling better signal separation.
3Productivity
If electrochemical method is used for glucose testing, then real-time glucose data can be collected continuously, but invasive sensor implantation is required
Solution Approach 1:
The patent replaces the invasive electrochemical sensor implantation with a non-invasive optical fluorescence detection system. This substitution eliminates the harmful invasive implantation while maintaining the capability for continuous real-time monitoring through repeated rapid measurements using portable fluorescence spectroscopy equipment.
Solution Approach 2:
The patent achieves continuous monitoring capability through rapid sequential fluorescence measurements. By using a portable fluorescence spectrometer that can perform measurements quickly and repeatedly, the system maintains continuous tracking of glucose levels without requiring invasive implantation, thus preserving the continuity of useful action while eliminating the harmful invasive aspect.
