Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spectroscopy analyzers are complex, expensive, and large due to the need for multiple spectrometers to cover multiple wavelength ranges, which is undesirable for high-volume product applications.
Innovation Solution
A compact spectroscopy analyzer integrates optical components to handle multiple wavelength ranges, including visible and near-infrared spectra, using a single device with a dichroic mirror-reflector to separate light into spectrometer and detector paths, allowing for efficient analysis of specimens with a small, uniform light spot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate spectrometers are used to cover multiple wavelength ranges, then the analyzer can determine multiple substances (glucose, creatinine, urea nitrogen) across different spectra, but the size and cost of the analyzer increases
Solution Approach 1:
The patent combines multiple spectrometers that cover different wavelength ranges into a single integrated spectrometer unit. This merging allows the device to analyze multiple substances across ultraviolet, visible, and infrared spectra while maintaining a compact form factor, thereby resolving the contradiction between versatility and device size.
Solution Approach 2:
The patent implements a universal spectrometer design that can handle multiple wavelength ranges (ultraviolet, visible, and infrared) within a single device. This multi-functional approach enables the analyzer to determine various substances including glucose, creatinine, and urea nitrogen without requiring separate specialized spectrometers for each wavelength range.

3Device complexity
If a broadband light source is used with a single spectrometer, then the device size is reduced, but the light output wavelengths must be highly stable which increases manufacturing complexity
Solution Approach 1:
The patent employs parameter changes by utilizing multiple light sources, each optimized for specific wavelength ranges (ultraviolet, visible, and infrared). This approach allows the system to maintain stable light output for each wavelength range by selecting appropriate light sources and optical parameters, thereby achieving reliable measurements across multiple spectra without requiring a single broadband source with extremely stable output.
