Gas-Containing Gel Material Retaining Functional Gas Bubbles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing gas-containing materials, such as hydrogen gas, are limited by the maximum concentration of dissolved hydrogen, which does not exceed 1.6 ppm, leading to insufficient functional gas release and reduced beneficial effects in applications like cosmetics, foods, and pharmaceuticals.
Innovation Solution
A gas-containing base material is developed with a gel-like composition that can retain functional gases at concentrations exceeding saturated solubility, using a method involving the dispersion of functional gases as fine bubbles in a raw material composition with a specific gelation temperature range, followed by cooling to solidify the composition, allowing for higher gas retention and release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If hydrogen gas is blown into purified water to generate microbubbles, then hydrogen-containing water with dissolved hydrogen concentration of 0.5 to 1.5 ppm is produced, but the amount of dissolved hydrogen gas does not reach 1.6 ppm or more of the saturated solubility
Solution Approach 1:
The patent changes the physical state parameter of the composition from liquid to solid gel form. By controlling the gelation temperature to be below the gas supply temperature, the functional gas can be retained in bubble state exceeding saturated solubility limits applicable to liquid solutions, thereby achieving hydrogen concentration above 1.6 ppm
Solution Approach 2:
The patent utilizes phase transition by cooling the liquid raw material composition containing dispersed functional gas bubbles below its gelation temperature to solidify it into a gel-like composition. This phase transition from liquid to solid traps the gas bubbles within the gel matrix, preventing gas escape and enabling retention of functional gas at concentrations exceeding saturated solubility
2Quantity of substance
If functional gas is dispersed as fine bubbles in liquid composition, then gas retention is improved, but shape collapse occurs during storage
Solution Approach 1:
The patent employs phase transition from liquid to solid gel by cooling below gelation temperature. This solidification provides structural rigidity to the composition, preventing shape collapse during storage while simultaneously trapping and retaining functional gas bubbles within the gel matrix
Solution Approach 2:
The patent creates a composite structure where functional gas bubbles are dispersed within a gelified matrix. The gel matrix provides mechanical support for shape stability while the dispersed gas bubbles maintain high functional gas content, achieving both shape stability and gas retention
3Quantity of substance
If gelation temperature is lowered to retain more gas, then gas concentration increases, but processing difficulty increases
Solution Approach 1:
The patent optimizes the gelation temperature parameter to fall within 0.5°C or higher and 65°C or lower. This parameter range allows the composition to remain processable at supply temperatures above gelation temperature while enabling effective gas retention upon cooling, balancing gas concentration achievement with manufacturing ease
