Engineering Contradiction Analysis
1Measurement precision
If traditional light splitting systems are used in spectrometers, then light can be dispersed into spectral lines, but the structure becomes complex and manufacturing difficulty increases
Solution Approach 1:
The patent integrates the light splitting function and the light guiding function into a single optical waveguide body. The optical waveguide body includes both the input waveguide for receiving light and the array of output waveguides for emitting spectral lines, eliminating the need for separate micro-nanostructures to derive spectral lines. This merging reduces structural complexity while maintaining spectral detection capability.
Solution Approach 2:
The optical waveguide body serves multiple functions: it acts as both the light splitting medium (through the dispersion grating) and the light guiding structure (through the array of output waveguides). This multi-functionality eliminates the need for additional specialized components, simplifying the overall device structure.
2Measurement precision
If micro-nanostructures are used to derive spectral lines, then spectral detection can be achieved, but light efficiency decreases
Solution Approach 1:
By combining the spectral line derivation function with the light guiding function in the same optical waveguide body, the patent eliminates additional light transmission interfaces and components. This reduces light loss and improves light efficiency while maintaining the capability to derive and detect spectral lines.
3Measurement precision
If traditional light splitting systems are used, then spectral lines can be dispersed, but manufacturing cost increases
Solution Approach 1:
The integration of multiple functions into a single optical waveguide body reduces the number of components that need to be manufactured and assembled. This simplification directly reduces manufacturing cost while preserving the spectral line detection capability.
4Measurement precision
If complex micro-nanostructures are implemented, then spectral line derivation is achieved, but detection process complexity increases
Solution Approach 1:
By merging the spectral line derivation function into the light guiding structure, the patent creates a more straightforward detection process. The array of output waveguides directly emits spectral lines without requiring additional complex derivation steps, simplifying the overall detection process.
