Vented Aerator Housing for Flush Mounting and Easy Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary installation components, such as aerators and flow regulators, face challenges in achieving both functional equivalence and aesthetic appeal while ensuring easy handling and minimizing installation space, often requiring additional tools or spouts that can be visually distracting and costly.
Innovation Solution
A sanitary installation component with a multi-part housing featuring an external thread for screwing into a water outlet, incorporating a ventilation channel and tool engagement surfaces, allowing for easy installation without additional spouts and maintaining aesthetic appeal, while integrating a jet splitter and diffuser to mix ambient air with water for a homogeneous jet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the aerator is screwed deeply into the water outlet to improve aesthetic appearance, then the visible surfaces are more uniform, but the downstream end face does not protrude beyond the water outlet making mounting and dismounting difficult without special tools
Solution Approach 1:
The housing is divided into multiple sections with different functions: a first housing section containing the aerator components and a second housing section extending beyond the water outlet to provide tool engagement surfaces. This segmentation allows the aerator to be screwed deeply for aesthetics while the separate second section provides the necessary gripping surfaces for mounting and dismounting operations.
2Ease of operation
If additional spouts are added to enable tool engagement for mounting, then mounting and dismounting becomes easier, but the aesthetic appearance is compromised and installation space increases
Solution Approach 1:
The tool engagement surfaces are merged into the second housing section that also serves as part of the aerator body. This integration eliminates the need for separate additional spouts while maintaining both the aesthetic appearance and the ease of mounting and dismounting operations.
3Ease of operation
If the aerator is designed to protrude beyond the water outlet to provide tool engagement surfaces, then mounting and dismounting becomes easier, but the aesthetic appearance is compromised and the installation space increases
Solution Approach 1:
Only the second housing section protrudes beyond the water outlet to provide tool engagement surfaces, while the first housing section containing the aerator components is positioned at or below the water outlet level. This localized protrusion minimizes the overall installation space while maintaining ease of operation and aesthetic appearance.
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 solution provides a sanitary fitting that ensures easy handling, maintains aesthetic appeal, reduces installation space, and avoids the need for additional spouts, while ensuring consistent jet quality and efficient water-air mixing.
Implementation Method 1
the jet splitter is designed to generate a negative pressure in order to draw ambient air into the housing interior through the at least one ventilation opening
Implementation Method 2
a jet splitter, which is designed as a perforated plate, can be inserted into the mounting housing and that the jet splitter is designed to divide the water flow into a corresponding number of individual jets
Implementation Method 3
a diffuser ring which surrounds the diffuser and that a flow channel, which tapers in the direction of flow, is provided between the inner circumference of the diffuser ring and the outer circumference of the diffuser. The individual jets separated in the diffuser are accelerated in this flow channel
Implementation Method 4
ventilated aerators, so-called jet aerators, have also been developed, which are intended to form a homogeneous, non-splashing, and gently aerated water jet
