Cistern Fill Valve Assembly for Left-Right Side Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve fittings for sanitary cisterns are not easily adaptable to change the connection of the water supply line from one side wall to the other, requiring complex conversions and limiting flexibility in installation positions.
Innovation Solution
A valve fitting design featuring a detachable shut-off valve connected to a pipe elbow with plug-in connections and a securing element, allowing the valve to be easily rotated and repositioned between left and right side wall installations without a flexible hose, and incorporating a lever-shaped actuating element for enhanced accessibility and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a rigid water section with fixed positioning is used, then manufacturing simplicity is improved, but adaptability to different installation positions deteriorates
Solution Approach 1:
The water section is divided into modular components (connecting element, shut-off valve, filling valve) that can be independently assembled and configured. The shut-off valve can be rotated to different positions while maintaining functional integrity, allowing adaptation to left or right side wall installations without requiring completely different rigid structures.
Solution Approach 2:
The shut-off valve is designed with rotational freedom around a horizontal axis, transforming from a fixed rigid connection to a dynamically adjustable connection. This allows the valve to be positioned in different orientations (left side or right side installation) while maintaining watertight sealing through the plug-in connection with securing element.
2Adaptability or versatility
If complex conversion mechanisms are used to change installation position, then adaptability is improved, but device complexity increases
Solution Approach 1:
The shut-off valve incorporates a simple rotational mechanism around a horizontal axis, allowing easy repositioning between left and right side wall installations. The plug-in connection with securing element provides a straightforward locking mechanism that requires no complex conversion tools or procedures, maintaining low device complexity while achieving high adaptability.
3Ease of manufacture
If the actuating element is positioned for standard installation, then manufacturing simplicity is improved, but ease of operation deteriorates when installation position changes
Solution Approach 1:
The actuating element is designed with universal accessibility from the front side regardless of whether the shut-off valve is installed on the left or right side wall. The lever-shaped design with horizontal rotation axis ensures that the actuating element always protrudes forward into the inspection opening area, maintaining ease of operation across different installation configurations without requiring specialized designs for each position.
Applied Scientific Principles

Implementation Method 1
a float connected to the filling valve can be moved by a rising water level in the cistern
Implementation Method 2
the actuating element of the shut-off valve in the functional position of the float by a substantially horizontal axis of rotation is rotatable
Implementation Method 3
the shut-off valve being detachably connected to the pipe elbow and the connecting element by plug-in connections, and the respective plug-in connection being provided with a securing element

AI summary
The invention relates to a valve armature (1) for the filling of a sanitary cistern (9), in particular a concealed cistern, comprising a connection element (2) for connecting the valve armature to a water supply line, a blocking valve (3) having an actuation element (4) for manually blocking the supply flow from the waster supply line, and a float-actuated filling vale (5), wherein the connection element (2), the blocking valve (3) and the filling valve (5) can be detachably connected to one another to form a stretch of water, such that water can be supplied from the water supply line into the internal space of the cistern (9), and wherein a float (6) connected to the filling valve can be moved by an increasing water level in the cistern, and the filling valve closes when a predetermined or predeterminable water level is reached, thereby interrupting the supply via the stretch of water. The valve armature (1) according to the invention is characterised in that the actuation element (4) of the blocking valve (3) can be rotated about a substantially horizontal axis of rotation (M) in the functional position of the float (6), wherein the blocking valve (3) is configured such that it can be deployed functionally in the valve armature (1) in at least two different positions, wherein the connection element (2) is/can be mounted in an opening (8) in the left lateral wall (9.1) of the cistern in one of the positions, and in an opening (8') in the right lateral wall (9.2) of the cistern in another of the positions, and wherein the actuation element (4) is accessible from the front side of the valve armature in the at least two positions of the blocking valve (3). The invention also relates to a sanitary cistern (9) having a valve armature (1) of this type.
