Adjustable Throttle Element for Sanitary Conduit Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water closet bowl flushing systems lack the ability to finely adjust the flushing water flow, limiting the precision of water flow throttling.
Innovation Solution
A line piece arrangement with a throttle element that includes fixed throttle webs and adjustable closure elements, allowing for incremental increases in throttling resistance by inserting closure elements between throttle webs, which can be broken or arranged in specific configurations to achieve desired flow control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a simple insert with channel and exit ports is used (DE 31 28 525), then the structure is simple and easy to manufacture, but fine adjustment of flushing water flow is not possible
Solution Approach 1:
The throttle element is segmented into multiple closure elements (first closure element, second closure element, etc.) that can be individually removed or retained. Each closure element corresponds to a specific throttling level, allowing incremental adjustment of water flow by selectively removing segments rather than requiring continuous adjustment mechanisms.
Solution Approach 2:
The closure elements are pre-configured in specific positions within the throttle element during manufacturing. The installer can directly remove the desired number of closure elements to achieve the required throttling level without requiring complex adjustment mechanisms or preliminary calibration steps.
2Measurement precision
If an inner part that can be pushed into the insert is used to adjust outlet cross-section, then some flow adjustment is possible, but fine adjustment in small steps is not achievable
Solution Approach 1:
Instead of a single movable inner part, the throttle element is divided into multiple discrete closure elements that can be independently removed. This segmentation enables fine adjustment in small, predetermined steps by removing individual closure elements rather than requiring continuous positioning of a single component.
Solution Approach 2:
The closure elements are designed as simple, inexpensive components that can be easily removed and discarded. Each closure element represents a discrete throttling level, and the system allows incremental adjustment by removing these simple components rather than requiring complex adjustable mechanisms.
3Adaptability or versatility
If multiple closure elements are connected via predetermined breaking point, then the installer can break off the desired number for customization, but the structure becomes more complex
Solution Approach 1:
The closure elements are connected via predetermined breaking points that allow easy separation. This segmentation enables the installer to customize the throttling level by breaking off the desired number of closure elements from the chain, providing adaptability without requiring complex assembly mechanisms.
Solution Approach 2:
The closure elements are pre-connected in a chain configuration with predetermined breaking points during manufacturing. This preliminary arrangement allows the installer to easily customize the throttling level by simply breaking off the required number of elements rather than requiring complex selection and assembly procedures.

AI summary
A pipe assembly (1) for a sanitary article comprises a pipe section (2) extending along a central axis (M) with a wall (3) and with an inlet (4) and an outlet (5), and a throttling element (6) arranged in the pipe section (2) by which the cross-section of the pipe section (2) can be changed. The throttling element (6) comprises at least one throttling rib (7) fixedly arranged in the pipe section (2), wherein the at least one throttling rib (7) projects into the cross-section of the pipe section (2). Furthermore, the throttling element (6) comprises at least one closure element (8, 9) which can be arranged in contact with the at least one throttling rib (7) in the pipe section to increase the throttling.
