Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for infusing gas into liquids struggle to achieve high levels of stable nanobubble formation and longevity, with previous systems producing larger bubbles that are not stable and have limited gas concentration and duration.
Innovation Solution
A system with a pressurized gas and liquid source, a 3D fluid path with radial bends and straight sections that creates multi-dense compaction of gas-infused carrier fluid, forming smaller and more stable nanobubbles, and a self-cleaning injection nozzle for efficient gas infusion and prevention of cavitation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If gas is infused into liquid using conventional methods, then gas infusion occurs, but the bubbles formed are large and unstable with short duration
Solution Approach 1:
The gas is divided into numerous small bubbles rather than forming large bubbles. The patent describes creating 'a large number of small bubbles' through the interaction of liquid jets and gas flow, segmenting the gas phase to achieve stable nanobubble formation that persists in the liquid for extended periods
Solution Approach 2:
The patent changes physical parameters including liquid pressure (5-50 psi), gas pressure (10-50 psi), and liquid flow rate (1-10 gallons per minute) to optimize bubble formation. By adjusting these parameters, the system achieves stable nanobubble formation with sizes of 0.5-200 nm that remain in the liquid for weeks rather than seconds
2Quantity of substance
If gas infusion level is increased, then more gas is infused into liquid, but stability and longevity of nanobubbles decrease
Solution Approach 1:
The system performs preliminary actions by pre-mixing gas and liquid under controlled conditions before the gas can coalesce into large bubbles. The liquid jets are positioned to create turbulence and distribute gas uniformly throughout the liquid stream, preventing premature bubble growth and maintaining stability even at high gas concentrations
Solution Approach 2:
The patent introduces a spatial dimension by using multiple liquid jets arranged in specific patterns (e.g., alternating sides of a central gas flow). This multi-dimensional arrangement ensures uniform gas distribution and prevents localized gas accumulation that would lead to unstable large bubble formation, allowing high gas concentration with maintained stability
3Productivity
If pressurization is applied to infuse gas into liquid, then gas infusion efficiency increases, but system complexity increases
Solution Approach 1:
The system uses the kinetic energy of the liquid flow itself to mix and distribute the gas, rather than requiring external mixing devices. The liquid jets create turbulence and shear forces that automatically break up gas bubbles and distribute them uniformly, making the system self-mixing and reducing mechanical complexity while maintaining high infusion efficiency
Solution Approach 2:
The patent employs pneumatic and hydraulic principles by using pressurized liquid jets (5-50 psi) and gas flow (10-50 psi) to achieve gas infusion. The system leverages fluid dynamics and pressure differentials to create efficient gas-liquid mixing without complex mechanical components, using only valves, pressure regulators, and nozzle arrangements

Function Achieved in This Case
The system generates smaller, more stable nanobubbles with higher gas concentration, achieving complete dissolution of gas in liquid, with a half-life of at least 30 days, and efficiently produces gas-infused liquids for various applications.
Implementation Method 1
a pressurized gas source; a pressurized liquid source; an enclosed vessel into which the pressurized gas and pressurized liquid are introduced such that the gas becomes infused into the liquid
Implementation Method 2
the fluid path includes multiple radial bends fixed in a three dimensional (3D) arrangement such that the when the gas-infused carrier fluid flows through the fluid path it is pressed inwardly of the 3D arrangement from multiple different directions to effect a multi-dense, orbital or spherical compaction of elements of the gas-infused carrier fluid, thereby forming the infused gas into nanobubbles
Implementation Method 3
The turbulent and laminar flow regions function to stabilize the infused gas in the liquid so that all or most of the gas will stably remain in the liquid for an extended period of time
Implementation Method 4
The turbulent and laminar flow regions function to stabilize the infused gas in the liquid
Implementation Method 5
a self-cleaning injection nozzle for efficient gas infusion and prevention of cavitation
