Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-pressure liquid and air are mixed to form jet stream, then cleaning capability is improved, but nanobubbles cannot be effectively incorporated in the mist
Solution Approach 1:
The device segments the mixing process into two distinct stages: first, nanobubbles are generated and incorporated into liquid to form nanobubble water; second, this nanobubble water is mixed with air in the two-fluid nozzle to create mist containing nanobubbles. This segmentation allows each stage to be optimized independently, ensuring nanobubbles are effectively incorporated while maintaining cleaning capability.
Solution Approach 2:
The nanobubble generation device performs preliminary action by creating nanobubble water before the mist generation process. This pre-prepared nanobubble water is then supplied to the two-fluid nozzle, ensuring that nanobubbles are already incorporated into the liquid phase before mixing with air, thus resolving the contradiction between mist formation and nanobubble incorporation.
2Speed
If mist is sprayed at high speed, then application effectiveness is improved, but nanobubbles are lost or destabilized
Solution Approach 1:
The device carefully controls pressure parameters throughout the system. The nanobubble generation device operates at specific high pressure to create stable nanobubbles, while the two-fluid nozzle is designed to mix air and nanobubble water at pressure ratios that maintain nanobubble stability during mist formation. By optimizing pressure parameters, the system achieves high-speed spray while preserving nanobubble integrity.
3Device complexity
If conventional mixing methods are used, then device simplicity is maintained, but nanobubble generation and mist injection cannot be achieved simultaneously
Solution Approach 1:
The device merges the nanobubble generation device with the two-fluid nozzle system in an integrated configuration. The nanobubble generation device supplies nanobubble water directly to the two-fluid nozzle, combining bubble generation and mist injection functions into a unified system. This merging enables simultaneous nanobubble generation and high-speed mist injection while maintaining reasonable device complexity through functional integration.

Implementation Method 1
high-pressure liquid such as water is supplied from an upstream side of a joint body 5, and high-pressure air including abrasive agents such as metal particles and sand particles is supplied from high-pressure air pipe 12, and then the high-pressure liquid and air are mixed at a position of an inside piece 8
Implementation Method 2
the gas-liquid mixed fluid may collide with dirt and paint etc. attached to an object to be polished as a high-speed jet stream, thereby scrubbing off the dirt and paint from the object
Implementation Method 3
the gas-liquid mixed fluid pushed out from a pressurized liquid pump 12 is put into a pumping tube 13 and is returned to a steady state to be in a supersaturated state, cavitation (a phenomenon in which bubbles are formed and collapse) is strongly generated, thus to deposit the dissolved air and gases

AI summary
A jet injection device that incorporates nanobubbles (ultrafine bubbles) in a mist includes: a two-fluid nozzle configured from a circular nozzle outer cylinder and an air connection tube integrally and perpendicularly connected to the nozzle outer cylinder; a nanobubble generation device that supplies the nozzle outer cylinder of the two-fluid nozzle with high-pressure nanobubble water; and a compressor that supplies the air connection tube of the two-fluid nozzle with high-pressure air. The gas-injected bubble water generated from the nanobubble generation device is pressure-fed to the nozzle outer cylinder of the two-fluid nozzle, and compressed air from the compressor is pressure-fed to the air connection tube of the two-fluid nozzle. In the two-fluid nozzle, the high-pressure gas-injected bubble water and the compressed air serve as a gas-liquid fluid mixture, and are injected at a high speed in mist form from a nozzle cylinder of the two-fluid nozzle.
