Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional micro bubble generating device is used, then bubbles at micro-scale level (several tens to several hundreds μm) can be generated, but bubbles at nano-scale level (less than 1 μm) cannot be generated
Solution Approach 1:
The invention changes the flow parameters by introducing a flow speed increasing part that accelerates liquid flow to high speeds. This parameter change enables the liquid flow to shear gas into nano-scale bubbles, resolving the contradiction between bubble size precision and application range by achieving nanometer-level precision through controlled flow velocity parameters
2Manufacturing precision
If the flow speed of liquid is increased to generate nano-scale bubbles, then bubble fineness is improved, but energy consumption increases
Solution Approach 1:
The invention uses hydraulic principles by designing a flow speed increasing part that utilizes liquid flow dynamics to generate high shear forces. This hydraulic approach enables nano-scale bubble generation through controlled liquid flow acceleration, achieving energy-efficient high-precision bubble production without requiring excessive energy input
3Manufacturing precision
If a complex structure is used to generate homogenized nano-bubbles, then bubble homogeneity is improved, but device complexity increases
Solution Approach 1:
The invention segments the device into three functional parts: flow speed increasing part, gas suction part, and super-micro bubble-containing liquid producing part. This segmentation achieves homogenized nano-bubble generation through specialized functional zones, resolving the contradiction by achieving high bubble uniformity through modular functional division rather than complex integrated structures

AI summary
To generate homogenized super-micro bubbles of nano-scale in a simple structure and at a low cost, a super-micro bubble generator has a cylindrical casing provided with an opening for the introduction of a liquid at one end and an outlet for delivery of the liquid at the other end, and the cylindrical casing includes: a flow speed increasing part for increasing the flow speed of the liquid introduced from the introduction opening; a gas suction part for drawing gas from the outside into the casing, wherein the pressure is decreased by a liquid flow whose flow speed is increased in the flow speed increasing part; and a super-micro bubble-containing liquid producing part for shearing, by the liquid flow whose flow speed is increased in the flow speed increasing part, the gas that is sucked by the gas suction part and generating a liquid including super-micro bubbles, in this order, from the introduction opening to the delivery opening.
