Solution Overview
Problem
Existing optical analysis systems struggle to accurately detect transmitted light and analyze components in samples with suspended materials, as incident light is often scattered or blocked by suspended particles, leading to inaccurate quantification due to changes in optical path length.
Innovation Solution
An optical analysis system that includes a container with light transmission walls and an ultrasonic irradiation unit, where the ultrasonic wave creates a transparent region by flocculating suspended materials, allowing unscattered light to pass through for analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a suspended sample containing scatterers is analyzed using conventional optical analysis, then the sample can be analyzed, but light is scattered or blocked by suspended particles causing inaccurate detection of transmitted light and incorrect quantification
Solution Approach 1:
The ultrasonic irradiation unit is activated before optical analysis to pre-flocculate suspended particles in the sample. This preliminary action aggregates the scatterers into larger clumps that can be more effectively removed or settled, preventing light scattering during the subsequent optical measurement and enabling accurate detection of transmitted light
Solution Approach 2:
The patent introduces an ultrasonic irradiation unit as an intermediary device between sample preparation and optical analysis. This intermediary treatment modifies the sample state by inducing flocculation of suspended particles, thereby eliminating the harmful scattering effect without directly altering the optical analysis system itself
2Adaptability or versatility
If suspended materials are present in the sample, then the sample represents real-world conditions, but optical path length changes due to multiple scattering preventing accurate component quantification
Solution Approach 1:
Before optical analysis, ultrasonic irradiation is applied to the suspended sample to induce flocculation of particles. This preliminary treatment creates a more uniform distribution of aggregated particles that settle or can be removed, establishing consistent optical path conditions that enable accurate component quantification while maintaining the ability to analyze real-world suspended samples
Solution Approach 2:
The patent changes the physical state parameters of suspended particles through ultrasonic irradiation, transforming them from dispersed individual particles to aggregated flocs. This parameter change in particle configuration eliminates multiple scattering effects while preserving the sample's compositional information, enabling accurate quantification
