Solution Overview
Problem
Current optical analyzers, such as single-beam and double-beam spectrometers, face challenges in quickly measuring absorption spectra of fluids due to slow wavelength switching and large size, which affects light intensity monitoring and makes them unsuitable for portable use.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-beam spectrometer uses a spinning beam splitter to switch detection light rays of different frequencies, then the device structure is simplified, but the wavelength switching speed is slow and real-time measurement of fast-flowing fluids cannot be achieved
Solution Approach 1:
The patent replaces the mechanical spinning beam splitter with a solid-state light source that directly emits multiple wavelengths. This eliminates the mechanical moving parts and achieves instantaneous wavelength switching, resolving the contradiction between simplified structure and fast switching speed.
Solution Approach 2:
The solid-state light source emits light rays of different wavelengths in a periodic sequence, allowing rapid wavelength switching without mechanical movement. This periodic emission pattern enables real-time measurement of fast-flowing fluids while maintaining structural simplicity.
2Productivity
If both detection light rays pass through the absorption cell before being received by detectors, then the measurement process is completed, but the light intensity of the original detection light rays cannot be monitored in real time
Solution Approach 1:
The patent divides the light path into two separate paths: one for measuring the absorption spectrum and another for monitoring the original light intensity. This segmentation allows simultaneous completion of measurement while preserving real-time monitoring capability through the reference detector.
3Adaptability or versatility
If multiple mirrors including a beam splitter are used to change light path direction, then the detection function is enhanced, but the device size increases and portable use becomes difficult
Solution Approach 1:
The patent extracts and removes the beam splitter and multiple mirrors from the system by using a solid-state light source that directly emits multiple wavelengths. This elimination of optical components significantly reduces device size while maintaining enhanced detection functionality through the solid-state emission approach.
4Device complexity
If the light intensity is too low after being split by the beam splitter, then the device structure is maintained, but the spectrum cannot be formed when light absorption of the liquid-to-be-measured is large
Solution Approach 1:
The patent replaces the beam splitter mechanism with a solid-state light source that emits multiple wavelengths directly. This substitution eliminates light loss from beam splitting while maintaining simple device structure, ensuring reliable spectrum formation even when the liquid-to-be-measured has large light absorption.
5Device complexity
If the angle of the beam splitter changes, then the device structure is maintained, but the changes in light intensity are affected
Solution Approach 1:
The patent replaces the angularly-adjustable beam splitter with a solid-state light source that emits multiple wavelengths. This eliminates the sensitivity to angle changes and associated manufacturing precision requirements, while maintaining structural simplicity through the solid-state emission approach.

AI summary
An optical analysis system and an optical analyzer thereof. The optical analyzer comprises a solid state light source emitter, a uniform mixing or light splitting assembly, a first optical receiver, and a second optical receiver. The solid state light source emitter comprises a light source comprising multiple light-emitting assemblies respectively radiating light having at least one light-emitting peak wavelength and at least one wavelength range; the light emitted by the multiple light-emitting assemblies passes through the uniformly mixing or light splitting assembly to form first light and second light which passes through a fluidic object to be detected to form detection light (i.e., after the second light passes through the fluidic object to be detected, the part of the second light not absorbed by the fluidic object to be detected forms detection light. The first optical receiver receives the first light. The second optical receiver receives the detection light.
