Solution Overview

Problem

Existing bubbling devices fail to mix air and water evenly, resulting in uneven bubble sizes and an inconsistent water flow with smooth and delicate bubbles.

Innovation Solution

A fine bubble generating device featuring a venturi tube mechanism with a neck portion, a bubble fining mechanism comprising first and second vortex members with slant holes, and an orifice board with jetting holes, which enhances the mixing of air and water by creating reverse vortexes and increasing the flowing speed of water to produce evenly sized bubbles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If air and water are mixed directly in the bubbling device without any mechanism, then the device structure is simple, but air and water are not mixed evenly resulting in bubbles of different sizes

Engineering Contradiction:
Improvebubble size uniformityVSAvoidmixing mechanism complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The mixing process is segmented into multiple stages: first the venturi tube creates preliminary mixing, then the first vortex member creates a first mixing zone, followed by the second vortex member creating a second mixing zone. This multi-stage segmentation allows progressive refinement of bubble size uniformity while managing overall device complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The vortex members act as intermediary elements between the venturi tube and the outlet. These intermediaries create controlled vortex flows that enhance mixing efficiency at each stage, serving as mediating structures that transform the flow characteristics to achieve uniform bubble distribution

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If a venturi tube mechanism is used to mix air and water, then the mixing efficiency is improved, but the device structure becomes more complex

Engineering Contradiction:
Improvemixing efficiencyVSAvoiddevice structure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The venturi tube mechanism serves multiple functions: it creates the pressure differential for air intake, initiates the mixing process, and generates flow velocity. By making this single component multi-functional, the patent improves mixing efficiency while minimizing the addition of separate dedicated components for each function

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

3Manufacturing precision

If vortex members with slant holes are used to create reverse vortexes, then the mixing of air and water is enhanced, but the manufacturing complexity increases

Engineering Contradiction:
Improvemixing enhancementVSAvoidvortex member manufacturing complexity
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The slant holes in the vortex members are designed with asymmetric orientations - the first vortex member has slant holes inclined in one direction while the second vortex member has slant holes inclined in the opposite direction. This asymmetric design creates the reverse vortex effect that enhances mixing, while the repetitive pattern of slant holes makes the manufacturing process standardized and manageable

Inventive Principle:
Principle #4Asymmetry
