Engineering Contradictions & Design Principles

VSEngineering 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 system

Engineering Contradiction:
Improveamount of microbubblesVSAvoiddevice complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent extracts the gas introduction function from the system by using only liquid flow through the atomizing portion. The liquid itself is atomized to generate mist with microbubbles, eliminating the need for separate pressurized gas supply equipment and simplifying the overall device structure while maintaining the ability to generate sufficient microbubbles for effective mist generation

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The liquid flowing through the atomizing portion serves dual functions: it is both the mist-generating substance and the medium that creates microbubbles through atomization. The system uses the liquid's own kinetic energy and the atomization process to generate microbubbles without requiring external gas pressurization, achieving self-service operation

Inventive Principle:
Principle #25Self-service

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

Engineering Contradiction:
Improveamount of ultrafine bubblesVSAvoidease of operation
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent removes the gas pressurization requirement from the operational process. By using only liquid flow through the atomizing portion, the system generates ultrafine bubbles through the atomization mechanism itself, making operation simpler and eliminating the need for operators to manage gas pressure while achieving sufficient ultrafine bubble generation for effective mist production

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The atomization process automatically generates ultrafine bubbles using the liquid's own flow characteristics and the nozzle geometry, without requiring external intervention or pressurized gas supply. The system self-regulates the bubble generation through the liquid flow rate and atomization parameters, improving ease of operation

Inventive Principle:
Principle #25Self-service

3Quantity of substance

If liquid and gas are mixed in the atomizing portion to generate mist with microbubbles, then the mist generation effectiveness improves, but the device complexity increases due to requiring both liquid and gas supply systems

Engineering Contradiction:
Improvemist generation effectivenessVSAvoiddevice complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent extracts the gas supply system from the mist generation process, relying solely on liquid flow through the atomizing portion. The liquid is atomized to create mist with inherent microbubbles, reducing device complexity by eliminating gas supply infrastructure while maintaining effective mist generation through optimized liquid atomization

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The liquid flow serves multiple functions simultaneously: it is the mist-generating substance, the medium for creating microbubbles through atomization, and the driving force for the entire process. This multi-functionality eliminates the need for separate gas supply systems, reducing device complexity while maintaining mist generation effectiveness

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

The nozzle effectively produces a large amount of mist with mixed microbubbles and ultrafine bubbles without the need for pressurized gas, enhancing mist generation efficiency.

Implementation Method 1

Parts of the liquid ejected from the first and second ejection ports collide with each other. The liquid ejected from the first and second ejection ports becomes a turning flow that is swirled due to the collision of the parts of the liquid. Air bubbles in the liquid ejected from the first and second ejection ports are pulverized into a large amount of mist by the collision 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.
