Tap Aerator Radial Compactness Stepped Diffuser Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tap aerators with diffusor rings require a large radial dimension due to the diffusor ring encompassing the diffusor, leading to space inefficiency and complex centering mechanisms.
Innovation Solution
The diffusor and diffusor ring are arranged with stepped ring-shaped holding regions, where the diffusor ring's outside edge is smaller and not encompassing the diffusor, allowing for a positive locking mechanism using undercuts in the mounting housing, enabling securement without radial extension, thus reducing the overall radial size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the diffusor ring encompasses the diffusor to secure it axially, then centering of the diffusor is achieved, but the radial dimension becomes large
Solution Approach 1:
The patent transitions from radial encompassment to axial stacking by arranging the holding regions at different heights in the axial direction. The diffusor ring's holding region is positioned at a lower axial level than the diffusor's holding region, allowing securement without radial extension.
Solution Approach 2:
The diffusor ring is positioned within the mounting housing such that its holding region abuts against the diffusor's holding region from below, creating a nested arrangement where components are stacked axially rather than extending radially.
2Stability of the object's composition
If the diffusor ring encompasses the diffusor, then axial securing is achieved, but the arrangement becomes complex
Solution Approach 1:
The securement function is divided between two separate holding regions at different axial levels, with the diffusor ring providing support from below and the mounting housing providing retention from above, eliminating the need for encompassment.
Solution Approach 2:
Instead of the diffusor ring encompassing the diffusor from the outside, the holding regions are arranged to abut against each other from different axial directions, inverting the traditional encompassment approach.
3Area of moving object
If the holding regions are arranged at different heights axially, then radial space is reduced, but axial space is increased
Solution Approach 1:
The patent accepts increased axial dimension as the trade-off for reduced radial dimension, utilizing the axial direction for stacking components that would otherwise require radial space for encompassment.

AI summary
The invention relates to a tap aerator (1) comprising a mounting housing and containing, in said mounting housing (2), an insert part that is designed as a jet divider and diffuser (7) which interacts with a diffuser ring (8). The annular retainer regions (7a) and (8a) of said diffuser (7) and diffuser ring (8), each arranged on the largest outer circumference, are located, when in a use position, in the interior of the mounting housing (2) at different height positions relative to one another in the axial direction, i.e. the retainer region (7a) of the diffuser (7) is not enclosed and the largest outer diameter of the diffuser ring (8) and its retainer region (8a) is only as large as, or if required even smaller than, the largest outer diameter of the diffuser (7) and its retainer region (7a). This allows the formation of an arrangement which saves space in the radial direction.
