Solution Overview
Problem
Existing methods for measuring fluid turbidity and composition, such as light scattering/absorption techniques, face limitations in accuracy, particularly in determining the cloudiness and turbidity of fluid flows.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If light scattering/absorption techniques are used to measure fluid turbidity and composition, then the measurement can be performed, but the accuracy of determining cloudiness and turbidity is insufficient
Solution Approach 1:
The patent introduces an image pattern slide as an intermediary object between the light source and the fluid sample. This slide contains specific patterns (such as grids or geometric shapes) that serve as a reference for comparing light scattering effects. By capturing images of this pattern through the fluid and comparing them to reference images, the system can accurately quantify turbidity and composition, resolving the accuracy-reliability contradiction in traditional light scattering methods.
2Measurement precision
If traditional light scattering techniques are used, then fluid composition can be measured, but particle scattering angle determination is imprecise
Solution Approach 1:
The patent replaces complex mechanical angular measurement systems with an optical imaging approach. Instead of using mechanical goniometers or complex detector arrays to measure scattering angles, the system uses a simple imager to capture images of an image pattern slide through the fluid sample. The scattering angle information is extracted computationally from image analysis, significantly simplifying the device while improving angular measurement precision.
3Measurement precision
If image pattern slide with light source and imager is used to project light beam through fluid flow, then turbidity and composition measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The patent designs a multi-functional measurement system where a single imager serves multiple purposes: capturing images of the image pattern slide for turbidity measurement, analyzing light scattering patterns for composition determination, and potentially monitoring fluid flow characteristics. The image pattern slide itself serves multiple functions as both a reference pattern and a scattering target. This multi-functionality reduces the need for separate specialized components, thereby limiting the increase in device complexity despite the improved measurement accuracy.
