Sanitary Drain Valve Actuation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drain valve operation systems in bathtubs and vanities are not reliably space-efficient and often have unfavorable guidance of pulling elements, leading to functional inconsistencies.
Innovation Solution
A compact design where the switching device is integrated into the drain valve housing, utilizing a cable pull with a sliding mechanism and rocker system for reliable actuation, allowing for concealed routing and effective power transmission, ensuring precise valve control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the switching device is arranged in the closure body, then the actuating part can be designed compactly, but the guidance of the pulling element becomes unfavorable and reliability decreases
Solution Approach 1:
The switching device is extracted from the closure body and relocated to the housing. This allows the pulling element to be routed favorably through the housing structure, improving guidance and reliability while maintaining compact actuating part design. The separation of the switching device from the closure body resolves the conflict between compactness and reliable pulling element guidance.
2Ease of operation
If a push button actuation system is used, then the valve can be operated simply, but the actuating part requires significant space
Solution Approach 1:
The switching device is merged with the housing structure, integrating the actuation mechanism into the existing spatial framework. This integration allows the push button actuation system to maintain its operational simplicity while significantly reducing the space required, as the switching device utilizes the housing's internal volume rather than requiring separate actuating part space.
3Device complexity
If the switching device is arranged on the housing side, then space is available for concealed routing, but the connection to the closure body must be extended
Solution Approach 1:
The pulling element is routed through the housing structure in three-dimensional space, utilizing available voids and channels rather than following a simple linear path. This spatial routing approach conceals the pulling element within the housing while managing the extended length through strategic positioning and routing through multiple dimensions, reducing visual complexity despite the increased length.

AI summary
The device (1) has a housing (5) fastened on a sanitary article (2) and mounted a pushbutton (7) for actuating a drainage valve. A cable (17) connects the pushbutton to a closure body, which is mounted in a displaceable manner in a housing of the drainage valve. A changeover device is mounted at the housing of the drainage valve, and is changed over under tension in each case of opening and closing the drainage valve. The changeover device has a changeover part and a rocker, which interacts for opening and closing the drainage valve.
