Microbubble Jet Assembly That Avoids Clogging Orifices

Solution Overview

Problem

Existing micro bubble generating apparatuses are inefficient and impractical for large-scale production due to high costs and clogging issues with small orifices, making them unsuitable for use with fluid dispensing fittings like hydrotherapy jets and shower heads.

Innovation Solution

A micro bubble generating system that includes a shell with a well for retaining a liquid and a micro bubble apparatus that provides a pressurized mixture of a second liquid and dissolved gas to create micro bubbles, which can be attached to hydrotherapy jets, shower heads, or nozzles, using a housing body with fluid passages to enhance bubble generation and prevent clogging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If small orifices and screens are used to generate micro bubbles, then micro bubble generation is achieved, but debris and contaminants clog the small orifices requiring expensive prefiltering and continuous cleaning

Engineering Contradiction:

Improvemicro bubble generationVSAvoidclogging of small orifices

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The bubble generation process is segmented into two distinct stages: first, large bubbles are generated through a larger orifice that is less prone to clogging; second, these large bubbles are mechanically disrupted into micro bubbles through interaction with turbulent water flow and internal structures within the jet assembly. This segmentation allows the initial bubble formation to occur through a larger opening while the micro-bubbling effect is achieved through fluid dynamics rather than forcing liquid through restrictive small orifices.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of the conventional approach of forcing liquid through small orifices to create micro bubbles, this invention inverts the process by first creating large bubbles through a larger orifice and then breaking them down into micro bubbles through turbulent flow and internal jet structures. This reversal eliminates the clogging problem associated with small orifices while still achieving the desired micro bubble generation.

Inventive Principle:

Principle #13The other way round (Inversion)

Core Design Contradiction:

Quantity of substanceVSUse of energy by moving object

Solution Approach 1:

This invention replaces the electrical/electrochemical process of electrolysis with a purely mechanical and fluid dynamic approach. Micro bubbles are generated through the mechanical disruption of larger bubbles by turbulent water flow and internal jet structures, eliminating the need for electrical energy input and expensive electrode systems while achieving large-scale micro bubble generation.
