Adjustable Throttle Element for Precise 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, resulting in inadequate control over the flushing process.
Innovation Solution
A line piece arrangement with a throttle element comprising fixed and movable throttle bars, allowing for adjustable throttling by moving the movable throttle bars relative to the fixed bars, which can be pivoted about the central axis, providing precise control over the water flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single throttling element is used in the pipe section, then the structure is simple, but fine adjustment of the rinsing water flow is not possible
Solution Approach 1:
The throttling element is divided into multiple independent throttling ribs (first throttling rib, second throttling rib, third throttling rib) that can be adjusted separately. Each throttling rib has its own adjustment mechanism allowing independent positioning to achieve fine control of water flow rate through cumulative throttling effects
Solution Approach 2:
The throttling ribs are designed to be movable relative to each other along the central axis of the pipe section. The adjustment mechanism allows dynamic repositioning of each throttling rib to change the effective cross-sectional area, enabling continuous fine adjustment of flow rate rather than fixed discrete settings
2Quantity of substance
If the movable throttle bar is positioned above the fixed throttle bar, then the flow rate is reduced, but the structure requires precise alignment
Solution Approach 1:
The adjustment mechanism is designed to automatically maintain proper alignment between movable and fixed throttling ribs during adjustment. The mechanical linkage and guide structures ensure that as one throttling rib is moved, the others follow corresponding paths, self-correcting alignment issues without requiring external precision alignment tools or procedures

AI summary
A conduit assembly (1) comprising a conduit 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 conduit section (2) by which the cross-section of the conduit section (2) can be changed. The throttling element (6) further comprises at least one throttling web (7) fixedly arranged in the conduit section (2) and at least one movable throttling web (8) which is movable relative to the fixed throttling web (7), wherein the throttling webs (7, 8) project into the cross-section of the conduit section (2).
