Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing devices for mixing air and liquid, such as foam dispensers, often fail to achieve thorough mixing of the two constituents before they are pushed through a mesh for foam production, affecting the quality of the produced foam.
Innovation Solution
A mixing chamber design that diffuses a single stream of air into multiple smaller streams and directs a single stream of liquid into an annular sleeve surrounding the air diffuser, ensuring thorough mixing of air and liquid before they pass through a mesh insert, with optional configurations for improved mixing patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single stream of air and liquid are pushed through a mesh for foam production, then the device structure is simple, but the mixing of the two constituents is insufficient
Solution Approach 1:
The air stream is divided into multiple smaller streams by the air diffusing structure with multiple air channels. This segmentation increases the surface area of air contact with liquid and improves mixing efficiency without significantly complicating the overall device structure
Solution Approach 2:
The liquid stream is transformed from a single central stream into an annular sleeve configuration, adding a dimensional change that surrounds the air streams. This geometric transformation enhances the contact between air and liquid phases, improving mixing while maintaining structural simplicity
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
This design enhances the mixing of air and liquid, resulting in improved foam quality by ensuring thorough initial mixing of the constituents before they are dispensed, applicable to any two fluid constituents.
Implementation Method 1
A single stream of air is diffused into a plurality of smaller streams of air. In the exemplary embodiment an air diffusing structure is used and is inserted into the air flow stream. When the single flow stream of air contacts the air diffusing structure, that single stream of air is separated and directed into a plurality of air channels which account for the plurality of smaller streams of air.
Implementation Method 2
The production of foam requires a mixing of the air and the liquid, and an initial mixing may occur prior to pushing those two constituents through a mesh or screen for bubble production by aeration.
Implementation Method 3
pushing those two constituents through a mesh or screen for bubble production by aeration

AI summary
A mixing chamber for two fluid constituents is disclosed which provides improved mixing before the mixture is pushed through a mesh insert for the production of foam. Foam production using air and liquid is the basis of the exemplary embodiment though the disclosed mixing chamber could be used for any two fluid constituents. A single stream of air is diffused into a plurality of smaller streams of air. The single stream of liquid is directed into an annular sleeve resulting in a thinner wall of liquid flow as compared to the entering liquid stream. This annular sleeve of a thinner wall of liquid flow surrounds the plurality of smaller streams of air. In a second embodiment, there are individual streams of liquid which are directed inwardly toward the individual streams of air. The mixing chamber construction is disclosed herein can be used for any two fluid constituents which would benefit for more thorough mixing.
