Innovation Solution
A method involving the preparation of initial fine bubble-containing liquid, followed by filtration to concentrate fine bubbles, and adjusting the throttle valve to control the flow rate and achieve a target density, utilizing a high-density fine bubble-producing apparatus that includes a fine bubble-containing liquid producing part, vaporizing part, and filtration system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If mechanical mixing is used to generate fine bubbles in water, then fine bubbles are produced, but the number of fine bubbles per unit volume is limited and cannot be dramatically increased
Solution Approach 1:
The patent extracts and removes large bubbles from the liquid through filtration, leaving behind a concentrated solution of fine bubbles. The filtration step separates the desired fine bubbles (which pass through the filter) from the unwanted large bubbles and liquid components, thereby increasing the density of fine bubbles in the remaining liquid.
Solution Approach 2:
The patent changes the physical parameters of the liquid system by controlling the flow rate through a throttle valve and adjusting the filtration process. By varying the flow rate and filtration conditions, the density of fine bubbles in the liquid can be controlled to achieve a target density, transforming the liquid from a low-concentration to a high-concentration fine bubble solution.
2Quantity of substance
If filtration is applied to concentrate fine bubbles, then high-density fine bubble-containing liquid is obtained, but the flow rate of liquid must be controlled to achieve target density
Solution Approach 1:
The patent implements a feedback control mechanism where the degree of opening of the throttle valve is adjusted on the basis of measurement results of bubble density. The actual bubble density is measured and compared with the target density, and the flow rate is automatically adjusted to maintain the desired density level, making the operation easier and more precise.
3Manufacturing precision
If high-speed swirling is used to reduce bubble sizes, then fine bubbles are generated, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical high-speed swirling systems with a simpler filtration-based approach. Instead of using high-speed mechanical mixing or swirling chambers to generate fine bubbles, the system uses a filtration process to separate and concentrate fine bubbles that are already present or gently formed, thereby achieving fine bubble generation with much simpler apparatus.
4Quantity of substance
If nanobubbles are generated by gas-liquid mixing with turbulence, then fine bubbles are produced, but additional components like filters and pressurization means are required
Solution Approach 1:
The patent extracts only the essential filtration function needed to concentrate fine bubbles, removing unnecessary complex components. By focusing on the core separation mechanism rather than attempting to generate nanobubbles through complex pressurization and turbulence systems, the apparatus achieves fine bubble concentration with fewer components.

AI summary
Initial liquid containing fine bubbles is produced by mixing water and air (step S11). Fine bubbles have diameters of less than 1 µm. The density of bubbles in the initial liquid is measured (step S13), and when the measured density is less than a target density (step S14), by increasing the density of fine bubbles in the initial liquid with using a filter that does not pass all fine bubbles, high-density fine bubble-containing liquid is easily acquired (step S15). When the density of bubbles in the initial liquid is greater than the target density, the initial liquid is diluted (step S16).
