Solution Overview
Problem
Current methods for generating stabilized, gas-infused liquids with high and ultra-high concentrations of infused gas are limited in their ability to maintain gas stability and efficiency, particularly in applications requiring large quantities of infused gas, such as medical treatments and chemical reactions.
Innovation Solution
A method involving the injection of a pressurized liquid and gas into a sealed vessel under high pressure, followed by stabilization through a tubular flow path to form nanobubbles, with repeated cycles of gas infusion and stabilization to achieve ultra-high concentrations of gas in liquids, such as oxygen in water, allowing for stable infusion even at high concentrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional gas infusion methods are used to generate stabilized, gas-infused liquids, then the process is simpler and requires less equipment, but the concentration of infused gas is limited and cannot achieve ultra-high concentrations
Solution Approach 1:
The gas infusion process is divided into multiple sequential stages, with each stage infusing a specific concentration range. The system segments the overall infusion target into manageable steps, progressing from low to ultra-high concentrations through controlled repeated cycles of infusion and stabilization.
Solution Approach 2:
Before attempting to achieve ultra-high gas concentrations, the system first establishes a stable base concentration through preliminary infusion cycles. This preliminary action creates a stabilized, gas-infused liquid that serves as the foundation for subsequent higher concentration infusions, preventing instability and gas loss.
2Quantity of substance
If high concentrations of gas are infused into liquids using conventional methods, then the gas concentration increases, but the gas becomes unstable and cannot be maintained
Solution Approach 1:
The system employs periodic cycles of gas infusion followed by stabilization periods. Each cycle consists of infusing gas to increase concentration, then allowing a stabilization phase where the liquid composition equilibrates. This periodic repetition enables progressive concentration increases while maintaining stability at each stage before proceeding to the next.
Solution Approach 2:
The system dynamically adjusts infusion parameters including pressure, flow rate, and cycle duration based on the current gas concentration level. As concentration increases from low to ultra-high ranges, parameters are modified to optimize both infusion efficiency and stability maintenance, preventing gas loss and composition instability.
3Quantity of substance
If repeated cycles of gas infusion are performed to achieve ultra-high concentrations, then the gas concentration increases significantly, but the process time increases
Solution Approach 1:
The system maintains continuous useful action by overlapping infusion and stabilization phases across multiple cycles. Rather than completing one full cycle before starting the next, the system continuously progresses through repeated infusion-stabilization sequences, maximizing productivity while achieving ultra-high concentrations through sustained operational flow.
4Quantity of substance
If high pressure is used to infuse gas into liquid, then the gas concentration increases, but the energy consumption and safety risks increase
Solution Approach 1:
The system applies high pressure partially during specific infusion phases rather than continuously, and uses moderate pressure during stabilization phases. This partial application of excessive force (high pressure) achieves the necessary gas concentration increases while reducing overall energy consumption and safety risks compared to maintaining high pressure throughout the entire process.

Implementation Method 1
discharging the gas-infused liquid from the sealed vessel, while still under the high pressure, into a tubular flow path arrangement which is configured to effect a multi-dense compaction of elements of the gas-infused liquid, and thereby form the infused gas into nanobubbles in the gas-infused liquid
Implementation Method 2
generating a gas-infused liquid by injecting a pressurized liquid and a gas into a sealed vessel under a high pressure of at least 20 psi

AI summary
A stabilized, gas-infused liquids containing ultra high concentrations of infused gas, produced by: generating a gas-infused liquid in a sealed vessel under a high pressure of at least 20 psi; stabilizing the gas-infused liquid by passing the liquid while still under the high pressure through a tubular flow path arrangement which compresses the infused gas into nano bubbles in the liquid; infusing an additional amount of the gas into the stabilized liquid by injecting the same, while still under high pressure, back into the sealed pressure vessel along with more of the gas; and again stabilizing the liquid by again passing liquid, while still under the high pressure, through the tubular flow path arrangement to thereby form the additional amount of infused gas into nano bubbles in the liquid.
