Optical Spectroscopy for Bubble Composition Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack practicality for accurately measuring the composition, particularly the concentration of ozone gas within bubbles in ozonated foams, as ozone decomposes quickly and existing measurement techniques are inaccurate due to decomposition during bubble collapse and absorption.
Innovation Solution
A method involving the optical spectroscopic assessment of bubbles by directing light through them while constrained between plates, measuring properties before and after passing through to estimate the chemical composition, specifically using wavelengths absorbed by ozone to quantify its concentration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If bubble collapse and liquid absorption methods are used to measure ozone concentration, then the measurement process can be completed, but the ozone gas decomposes during the process leading to inaccurate measurements
Solution Approach 1:
The patent applies preliminary action by measuring the ozone concentration in the bubble before the bubble collapses and before significant decomposition occurs. The measurement is performed while the bubble is still intact, capturing the ozone concentration at the time of measurement rather than after decomposition has occurred during collapse and absorption processes.
Solution Approach 2:
The patent replaces the mechanical/physical collapse and absorption method with an optical measurement method. Instead of relying on bubble collapse and liquid absorption to bring ozone into contact with a detector, the system uses optical sensors to detect ozone concentration through the bubble wall, substituting a non-invasive optical measurement for the destructive mechanical process.
2Measurement precision
If non-invasive optical measurement methods are used, then the bubble structure is preserved, but the measurement complexity increases
Solution Approach 1:
The patent uses the bubble wall itself as an intermediary medium that allows optical measurement without direct contact with the bubble interior. The optical sensor measures ozone concentration through the transparent or translucent bubble wall, using the wall as a mediator that enables non-invasive measurement while preserving the bubble structure.
Solution Approach 2:
The patent utilizes optical properties such as light absorption and transmission through the bubble wall to detect ozone concentration. By measuring changes in light intensity or spectral characteristics as light passes through the bubble wall, the system can determine ozone concentration without physically disrupting the bubble, leveraging optical color and intensity changes for detection.

Function Achieved in This Case
This approach allows for accurate and reliable determination of ozone concentration within bubbles, overcoming the limitations of rapid ozone decomposition and providing a precise analysis of bubble composition without disrupting the bubble.
Implementation Method 1
electromagnetic radiation, preferably light, is directed through the bubble and the light passing through the bubble has one or more of its properties measured for comparison between the light emitted and the light that has passed through the bubble
Implementation Method 2
using wavelengths absorbed by ozone to quantify its concentration

AI summary
A method of spectroscopically assessing the chemical composition of a bubble while the bubble constrains a gas within the interior of the bubble by passing light passing through the bubble and comparing properties of the light before and after the light has passed through the bubble. The bubble is located, preferably compressed between a first plate and a second plate providing a compressed bubble with relatively flat first polar end wall portion adjacent the first plate in a relatively flat second polar end wall portion adjacent a second plate and directing the light to pass through the bubble via the first and second polar end wall portions.
