Jet Aerator Handle Pivoting for Tool-Free Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jet regulators for sanitary outlet fittings require additional tools for assembly and disassembly, which are often misplaced or lost, and their design can compromise aesthetics or require storage of tools that are rarely needed.
Innovation Solution
A jet regulator with a handle designed as a holding bracket that can pivot between a use position protruding beyond the outlet end face and a ready position adjacent to the inner circumference, allowing for tool-free assembly and disassembly, with the handle integrated into the regulator or intermediate holder to prevent loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate assembly and disassembly tool is used, then the jet regulator can be installed and removed, but the tool is often misplaced or lost and is not available when needed
Solution Approach 1:
The patent integrates the assembly and disassembly function directly into the jet regulator housing by providing a crown-shaped front edge with alternating projections and indentations. This eliminates the need for a separate tool, combining the regulator and tool functions into one component, thereby ensuring the tool is always available and cannot be lost.
Solution Approach 2:
The jet regulator housing is designed to serve itself for assembly and disassembly operations. The crown-shaped front edge with projections and indentations allows the regulator to function as its own tool, enabling users to perform installation and removal without requiring external tools that could be misplaced or lost.
2Ease of operation
If the jet regulator housing protrudes sufficiently beyond the outlet end to allow manual grasping, then assembly and disassembly can be performed manually, but this impairs the aesthetics of the outlet fitting
Solution Approach 1:
The patent applies local quality by providing the crown-shaped front edge with projections and indentations only at the specific location where tool engagement is needed (the front edge of the housing), while the rest of the housing maintains a smooth, aesthetically pleasing appearance that does not protrude excessively beyond the outlet end.
3Volume of moving object
If the entire length of the aerator housing is inserted into the outlet end, then a compact design is achieved, but a sleeve-shaped turning tool is required which must be stored and is rarely needed
Solution Approach 1:
The patent merges the tool function into the aerator housing itself by designing the crown-shaped front edge with projections and indentations that serve as the tool working surface. This eliminates the need for a separate sleeve-shaped turning tool, reducing device complexity while maintaining the compact installation design where the entire housing is inserted into the outlet end.

AI summary
The aerator (1) has a housing insertable into an outlet end (9) of a sanitary outlet fitting (10) directly or with an intermediate holder (12). An external thread, a bayonet extension and a plug-in/rotary connection part are respectively connected with an internal thread, a bayonet cavity and a complementary plug-in/rotary counterpart at the outlet end of the outlet fitting. A C-shaped handle (15) i.e. retaining clip, is provided at a front region of the outlet end for manual gripping of the aerator and/or at the intermediate holder for screwing and unscrewing from the outlet fitting.
