Rotor-Gap Bubble Formation for Compact Ultrafine Bubble Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bubble formation apparatuses require a large configuration due to the inclusion of a porous body and a cylinder, which increases the overall size and complexity.
Innovation Solution
A bubble formation apparatus that forms bubbles by periodically repeating pressurization and depressurization of a gas-liquid mixture in a gap between a rotor and a to-be-pressed surface within a container, eliminating the need for a porous body and cylinder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a porous body and cylinder are included in the bubble formation apparatus, then bubbles can be formed effectively, but the overall configuration becomes large and complex
Solution Approach 1:
The patent extracts and eliminates the porous body and cylinder from the bubble formation apparatus. Instead of using these traditional components, the invention uses a rotor that directly generates bubbles through its rotation in a gas-liquid mixed fluid, thereby simplifying the device configuration while maintaining bubble formation effectiveness
Solution Approach 2:
The patent merges the bubble generation function directly into the rotor component. The rotor simultaneously performs the functions of fluid mixing and bubble generation by rotating in the gas-liquid mixed fluid, eliminating the need for separate porous bodies and cylinders, thus reducing device complexity
2Reliability
If a porous body and cylinder are used for bubble formation, then the device can operate, but the configuration becomes large
Solution Approach 1:
The invention removes the porous body and cylinder components that occupy significant space in traditional bubble formation apparatuses. The rotor-based system achieves the same bubble formation capability in a more compact configuration, reducing the overall device volume
Solution Approach 2:
Instead of using a porous body to release gas into liquid (traditional approach), the invention inverts the approach by rotating a rotor in a gas-liquid mixed fluid to generate bubbles. This inversion eliminates the need for large porous structures and guiding cylinders, significantly reducing device volume
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus achieves efficient bubble formation without a large configuration, enhancing bubble density and allowing for the formation of ultrafine bubbles through rotor rotation and pressurization-depressurization cycles.
Implementation Method 1
a bubble is formed by periodically repeating pressurization and depressurization of a mixture of the gas and the liquid in a gap between the to-be-pressed surface and a portion, pressed against the to-be-pressed surface, of the rotor due to the rotation of the rotor by the rotary device
Implementation Method 2
Bubbles are formed by stirring the gas, guided to the periphery of the rotor, by the rotor

AI summary
A bubble formation apparatus (500) includes: a rotor (100); a container (200) in which the rotor (100) is housed together with a liquid (LQ) and a gas (GS); and a rotary device (300) that causes rotation of the rotor (100) with the rotor (100) being pressed against an inner lower surface (221) that is the inner surface of the container (200). A bubble is formed by periodically repeating pressurization and depressurization of a mixture of the gas (GS) and the liquid (LQ) in a gap between the inner lower surface (221) and a portion, pressed against the inner lower surface (221), of the rotor (100) due to the rotation of the rotor (100) by the rotary device (300).
