Sanitary Unit Handle External Actuation Water Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary units require users to reach into the water flow to adjust functional positions, making handling cumbersome and inconvenient.
Innovation Solution
A sanitary unit with a sleeve-shaped outlet mouthpiece featuring a handle that can be adjusted via a transmission element guided axially, allowing the actuating element to be gripped externally without entering the water stream, and an outlet structure that connects the actuating element to the transmission element, facilitating easier handling and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the actuating element is positioned inside the water flow for adjustment, then the transmission element can directly actuate the functional element, but the user must reach into the water flow making handling cumbersome
Solution Approach 1:
The patent introduces an intermediary transmission element (a transmission rod or linkage mechanism) that bridges the gap between the externally positioned actuating element and the internally located functional element. This intermediary component transmits the actuating force through the outlet mouthpiece wall, allowing the user to operate the device from outside the water flow while still controlling the functional element positioned inside the water stream.
Solution Approach 2:
The patent relocates the actuating element from the internal water flow dimension to the external ambient space dimension. By positioning the actuator outside the water stream and using a transmission mechanism that penetrates through the outlet mouthpiece wall, the system separates the user interaction space from the water flow space, eliminating the need for users to reach into the water.
2Ease of operation
If the actuating element is positioned outside the water flow for easier handling, then user convenience is improved, but a transmission mechanism through the outlet mouthpiece is required increasing device complexity
Solution Approach 1:
The patent merges the transmission element with the outlet mouthpiece structure itself. The transmission rod is integrated into the outlet mouthpiece wall, and the actuating element is combined with the outlet structure in such a way that the transmission mechanism becomes part of the overall housing structure rather than a separate additive component. This reduces the perceived complexity by consolidating functions into existing structural elements.
Solution Approach 2:
The outlet mouthpiece structure itself serves the dual function of both containing the water flow and housing the transmission mechanism. The wall of the outlet mouthpiece acts as the transmission pathway, eliminating the need for separate complex transmission housings or additional structural components. The existing structure serves its own transmission function.
3Adaptability or versatility
If ventilation openings are closed for unventilated spray jet, then spray jet performance is improved, but ambient air cannot be mixed with water for soft sparkling jet
Solution Approach 1:
The patent designs the functional element with multi-functionality, where a single component structure serves multiple purposes: it acts as both the spray jet generator and the ventilation control mechanism. The same element that creates the spray jet also controls the ventilation openings, allowing one actuating element to control both jet type and ventilation status without requiring separate control mechanisms.
Solution Approach 2:
The patent combines the ventilation control function with the jet regulation function into a single integrated functional element. The component that regulates the water flow for jet formation also controls the ventilation openings, merging two control functions into one element. This allows simultaneous control of both spray jet and soft sparkling jet modes through a single actuating mechanism.

AI summary
The invention relates to sanitary unit (1, 116, 118) which has a sleeve-like outlet mouthpiece (2), which (2) can be installed on a water outlet of a sanitary outlet fitting and has a sleeve interior, into which is inserted a sanitary functional unit (5) with at least one functional element (5), which (5) has a component (6), which (6) can be adjusted between at least two functional positions, by means of an externally accessible handle, via a transmission element (9) which is guided in an axially displaceable manner in the functional element (5). The sanitary unit according to the invention is characterized in that the handle is configured in the form of an actuating element (7) which is retained in a displaceable manner on the outer circumference of a sub-region, forming part of the outlet mouthpiece (2), which projects beyond the water outlet of the outlet fitting, and in that the actuating element (7), which serves as a handle, has retained on it a water-jet-permeable or water-jet-guiding outlet structure (8), which connects the actuating element (7) to the transmission element (9).
