Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If pressurized gas is introduced into the atomizing portion to generate mist with microbubbles, then the amount of microbubbles mixed and dissolved increases, but the device complexity and operational complexity increase due to requiring pressurized gas supply systems
Solution Approach 1:
The invention extracts and eliminates the pressurized gas supply system from the mist generation device. Instead of introducing pressurized gas into the atomizing portion, the patent uses only liquid supply, allowing the liquid flow dynamics and collision mechanisms to naturally generate and mix microbubbles without external gas pressurization equipment.
Solution Approach 2:
The system enables self-generation of microbubbles through the inherent dynamics of liquid ejection and collision. The liquid flowing through the nozzle holes and colliding in the atomizing portion automatically entrains and pulverizes air, creating microbubbles without requiring external gas supply or pressurization systems.
2Quantity of substance
If pressurized gas is introduced to increase ultrafine bubbles in mist, then the amount of ultrafine bubbles mixed and dissolved increases, but the ease of operation deteriorates due to requiring pressurized gas introduction
Solution Approach 1:
The invention removes the requirement for pressurized gas introduction systems. The atomizing portion is designed to generate ultrafine bubbles solely through liquid flow dynamics, collision, and shearing forces, eliminating the need for complex gas supply infrastructure and simplifying operation.
Solution Approach 2:
The system performs self-pulverization of air bubbles through the kinetic energy of ejected liquid streams. The collision and turning flow mechanisms automatically create ultrafine bubbles without external intervention or pressurized gas, making the system easier to operate and maintain.
3Quantity of substance
If liquid is ejected at acute angles to generate collision and turning flow, then the amount of mist with microbubbles and ultrafine bubbles increases, but the manufacturing precision requirements increase for nozzle hole angles and positions
Solution Approach 1:
The nozzle is divided into multiple nozzle holes (first and second nozzle holes) with specific angular orientations. This segmentation allows each hole to contribute to the collision and turning flow patterns, distributing the precision requirements across multiple elements rather than requiring a single complex structure.
Solution Approach 2:
The invention specifies angular parameters (acute angles for nozzle holes relative to the plate surface) and dimensional parameters (hole intervals) that optimize mist generation through collision. By carefully controlling these geometric parameters, the system achieves high mist production while maintaining manufacturability through standardized angular specifications.
4Quantity of substance
If liquid streams are made to collide to create turning flow and pulverize bubbles, then the amount of mist with mixed microbubbles and ultrafine bubbles increases, but the device complexity increases due to requiring multiple ejection ports and specific hole arrangements
Solution Approach 1:
The atomizing portion is segmented into multiple nozzle holes arranged at specific angles and intervals. This segmentation creates multiple liquid streams that collide to generate turning flow and pulverize bubbles, achieving high mist generation through distributed simple elements rather than a single complex mechanism.
Solution Approach 2:
The invention combines the functions of multiple nozzle holes, liquid ejection, air entrainment, bubble pulverization, and mist generation into a single integrated atomizing portion. This merging of functions into one component reduces overall device complexity compared to having separate systems for each function.
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
Generates a large amount of mist with mixed microbubbles and ultrafine bubbles by ejecting liquid into outside air without the need for pressurized gas, enhancing mist production efficiency.
Implementation Method 1
Parts of the liquid ejected from the first and second ejection ports at the first and second acute angles collide with each other
Implementation Method 2
The liquid ejected from the first and second ejection ports at the first and second acute angles becomes a turning flow that is swirled due to the collision of the parts of the liquid
Implementation Method 3
The liquid ejected from the first and second ejection ports at the first and second acute angles and the air bubbles (gas/air) in the liquid are pulverized (sheared) by the collision (splash) of the parts of the liquid and the turning flow

AI summary
The present invention provides a mist generating nozzle capable of generating a large amount of mist (liquid droplets) in which a large amount of microbubbles and a large amount of ultrafine bubbles are mixed and dissolved by ejecting a liquid into outside air. The present invention includes a nozzle main body (Y1). The nozzle main body (2) includes first and second ejection ports (4, 5), first and second inflow ports (6, 7), a first nozzle hole (8) connected to the first ejection port (4) and the first inflow port (6), and a second nozzle hole (9) connected to the second ejection port (5) and the second inflow port (7). The nozzle main body (Y1) ejects water from the first and second ejection ports (4, 5) into outside air at first and second acute angles (θ1, θ2) to cause parts of the liquid ejected from the first and second ejection ports (4, 5) to collide with each other and turn the ejected water by the collision.
