Compact Outlet Nozzle With Detachable Jet Regulator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outlet mouthpieces for sanitary water fittings require significant space and manufacturing effort to accommodate valve units and aerators, leading to inefficiencies in producing a homogeneous, sparkling-soft, and non-splashing water jet.
Innovation Solution
A compact outlet mouthpiece design featuring a valve unit that can be moved between open and closed positions without a protruding handle, incorporating a detachable jet regulator unit with a driver system for torque-proof connection, allowing for space-saving installation and easy replacement, and a self-closing mechanism to conserve water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a compact outlet mouthpiece design is used to reduce space and manufacturing effort, then space requirements and production complexity are reduced, but the functionality to produce a homogeneous, sparkling-soft, and non-splashing water jet may be compromised
Solution Approach 1:
The jet regulator unit is detachably inserted into the receiving cavity of the outlet mouthpiece, allowing the components to be nested within each other. This nesting approach reduces the overall space requirement and simplifies manufacturing while maintaining the functional integrity of the water jet formation system.
Solution Approach 2:
The outlet mouthpiece is divided into separate components: a connection section, a receiving section, and a detachable jet regulator unit. This segmentation allows each component to be manufactured separately with optimized complexity, then assembled to achieve the desired water jet quality without requiring the entire assembly to be manufactured as a single complex unit.
2Ease of repair
If a detachable jet regulator unit is used to simplify installation and replacement, then ease of maintenance is improved, but the reliability of the connection may be compromised
Solution Approach 1:
The jet regulator unit is pre-equipped with an external thread that corresponds to an internal thread in the receiving section, allowing for a secure and reliable connection to be established before use. This preliminary threading design ensures that when the components are assembled, they form a stable and dependable connection that maintains reliability while remaining easily replaceable.
3Volume of moving object
If the valve unit is integrated into the outlet mouthpiece without a protruding handle, then space requirements are reduced, but the ease of operation may be compromised
Solution Approach 1:
The valve unit is merged with the outlet mouthpiece body, eliminating the need for a separate protruding handle. The valve is directly integrated into the compact structure, allowing operation within the limited space while maintaining functional accessibility through the streamlined design.

AI summary
The invention relates to an outlet nozzle (1) which can be attached to an outlet fitting, or to a similar outlet end of a sanitary water line, and comprises a valve unit (3), which is displaceable between a locking position closing the water line and an open position releasing the water line, wherein at least one aerator unit having a jet divider, homogenizer, and/or flow rectifier, a shower unit, or similar jet former, is provided in the outlet nozzle (1). The outlet nozzle (1) according to the invention is characterized by the low space requirement and production costs thereof (compare FIG. 2).
