Solution Overview
Problem
Existing methods for measuring the composition of substances in reaction vessels face challenges such as contamination, changes in composition due to gas, liquid, or solid additions, and difficulty in performing continuous measurements without mixing samples, leading to inaccurate analysis.
Innovation Solution
An optical analysis apparatus with a flow passage system that introduces bubbles to divide the substance, allowing for precise measurement by irradiating the substance and bubbles with light, thereby preventing mixing and ensuring accurate analysis at the sampling time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the substance is extracted using an instrument such as a dropper or syringe, then measurement can be performed, but continuous measurement is difficult and contamination or composition changes occur
Solution Approach 1:
The substance flow is segmented into discrete portions by introducing bubbles that divide the continuous flow into separate segments. Each segment contains a specific sample taken at a specific time, allowing continuous measurement without mixing between samples while maintaining measurement accuracy.
Solution Approach 2:
Bubbles are introduced as an intermediary substance to divide and separate the liquid flow. The bubbles act as physical barriers that prevent mixing between different samples while allowing the measurement to proceed continuously through the flow passage.
2Quantity of substance
If the lid of the vessel is opened to extract the substance, then the substance can be sampled, but gas is released or air enters causing composition changes or contamination
Solution Approach 1:
The harmful effect of opening the lid is eliminated by extracting only the necessary function (substance sampling) through the closed lid structure. Sampling ports or injection points are provided in the lid, allowing substance extraction without opening the vessel, thus preventing contamination and composition changes.
3Productivity
If the substance is circulated through flow passages, then continuous measurement is possible, but samples taken at different times mix together causing inaccurate analysis
Solution Approach 1:
The continuous flow in the flow passage is segmented into discrete portions by introducing bubbles. Each bubble divides the flow, creating separate segments that contain samples from specific time points. This segmentation prevents mixing between samples while allowing continuous circulation and measurement.
Solution Approach 2:
Bubbles are introduced periodically into the flow passage at regular intervals to divide the continuous substance flow. This periodic introduction of dividing elements ensures that samples taken at different times remain separated, maintaining analysis accuracy while enabling continuous measurement.
