Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bubble removal methods for viscous fluids face challenges in increasing removal rates without enlarging the device, as they require significant stiffness for pressurization and depressurization, leading to increased device size.
Innovation Solution
A continuous bubble removal method and apparatus that uses a main container, a basic pressurization container, and a movable portion to iteratively pressurize and depressurize the target liquid, with a larger opening area for the supporting portion compared to the connecting portion, allowing for increased pressure application while maintaining a compact device size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the stiffness of the pressurization and depressurization mechanism is significantly increased to improve bubble removal rate, then the removal rate of bubbles increases, but the device size becomes larger
Solution Approach 1:
The device is divided into two functional sections: a first section with a smaller cross-sectional area for applying pressure changes, and a second section with a larger cross-sectional area for bubble removal. This segmentation allows the pressure-generating portion to be compact while the bubble treatment portion has sufficient volume, resolving the contradiction between compact size and effective bubble removal rate.
2Productivity
If pressurization and depressurization is performed from multiple locations in the container, then the bubble removal efficiency improves, but the device complexity increases
Solution Approach 1:
Instead of adding multiple pressurization locations in the horizontal plane (which would increase complexity), the invention utilizes the vertical dimension by creating a pressure gradient from the first section to the second section. The pressure changes propagate vertically through the liquid, achieving multi-location effect without requiring multiple independent pressurization mechanisms.
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
This approach enhances bubble removal rates by applying stronger pressure oscillations to the bubbles, improving the degassing effect while preventing the device from becoming larger, thus optimizing efficiency and size.
Implementation Method 1
iteratively pressurizing and depressurizing the target liquid from a region via the basic operating liquid by displacing, in a reciprocating manner, the basic movable portion
Implementation Method 2
the volume of bubbles in the liquid iteratively decreases and increases, and as a result, shearing occurs in the liquid around the bubbles. This shearing causes the viscosity of the liquid around the bubbles to decrease, such that the rate at which the bubbles rise due to buoyancy increases
Implementation Method 3
The basic movable portion iteratively applies force to the basic operating liquid held in the basic pressurization container, by being displaced in a reciprocating manner with respect to the basic pressurization container
Implementation Method 4
shearing occurs in the liquid around the bubbles. This shearing causes the viscosity of the liquid around the bubbles to decrease
Implementation Method 5
This shearing causes the viscosity of the liquid around the bubbles to decrease, such that the rate at which the bubbles rise due to buoyancy increases

AI summary
A continuous bubble removal method includes: preparing a main container, a basic pressurization container that connects to the main container and holds a basic operating liquid, and a basic movable portion that is displaceably attached to the basic pressurization container; flowing target liquid through the main container, the liquid including a bubble; and iteratively decreasing and increasing a volume of the bubble by iteratively pressurizing and depressurizing the target liquid from a region via the basic operating liquid by displacing, in a reciprocating manner, the basic movable portion, the region being surrounded by a basic connecting portion of the basic pressurization container that is closer to the main container than the basic supporting portion, wherein an opening area of the basic supporting portion is larger than an opening area of the basic connecting portion.
