Coaxial Siphon Conveyance Assembly for Flooded Vertical Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid conveyance systems in vertical sections face issues with space inefficiency, aesthetic concerns, increased complexity and cost, and potential leaks due to siphon assemblies that require multiple joints and deviate from the vertical axis, leading to inaccurate measurements and air ingress.
Innovation Solution
A coaxial siphon-effect section integrated into a single-monolithic piece maintains the vertical conduit's axis, minimizing space, reducing joints, and ensuring continuous flooding, allowing for symmetrical velocity profiles and efficient installation of measurement systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional siphon assembly is installed in a vertical conduit, then the liquid column is maintained for flooding, but the vertical axis shifts and coaxiality is lost
Solution Approach 1:
The siphon assembly is divided into separate modular components: a vertical section, a siphon section with bends, and a downstream section. This segmentation allows each component to be optimized independently, with the siphon section providing the necessary liquid column stability while the modular design manages the axis shift through controlled transitions between sections.
2Stability of the object's composition
If a conventional siphon assembly is installed, then flooding is maintained, but more space is required
Solution Approach 1:
The siphon section is integrated within the vertical conduit structure, with the siphon bends and liquid column nested within the overall conduit volume. This nesting approach allows the siphon functionality to be incorporated without requiring a completely separate external structure, thereby reducing the total space required while maintaining the flooding effect.
3Stability of the object's composition
If a conventional siphon assembly is installed, then flooding is maintained, but aesthetic problems occur in visible constructions
Solution Approach 1:
The aesthetic considerations are applied locally to the visible portions of the conduit. The vertical sections are designed with smooth, clean lines suitable for visible installations, while the siphon bends are confined to less visible areas or designed with radii that maintain acceptable aesthetics. This local differentiation allows the flooding function to be maintained while preserving the visual appeal of visible conduit sections.
4Ease of manufacture
If independent plastic injection moulded parts are joined, then manufacturing is enabled, but the number of joints increases
Solution Approach 1:
Multiple conduit sections and the siphon assembly are merged into a single integrated component manufactured by plastic injection moulding. This consolidation eliminates the need for multiple separate joints, reducing the overall number of connection points while maintaining the manufacturing advantages of injection moulding. The single-piece construction directly addresses the leak risk associated with multiple joints.
5Adaptability or versatility
If more joints are present, then assembly flexibility is improved, but leakage risk increases
Solution Approach 1:
The conduit sections and siphon assembly are combined into a single integrated component, eliminating multiple joints and thereby reducing leakage risk. This merging maintains sufficient adaptability through the design of the siphon section itself, which can accommodate various installation requirements through its geometric configuration rather than requiring multiple separate jointed sections.
6Ease of operation
If siphon assembly is exposed, then functionality is visible, but measurement accuracy decreases
Solution Approach 1:
The measurement system is extracted and positioned in a separate location from the visible siphon assembly. This separation allows the siphon functionality to remain visible and operational while the measurement instruments are placed in a protected environment where they can maintain accurate measurements without being affected by the siphon's operational dynamics or visual exposure.

AI summary
The present invention relates to an assembly, segment, section or similar for conveying liquids which is fitted to an installation for conveying and supplying such liquids, in a vertical or approximately vertical section of the installation, with the liquid entering at the top and leaving at the bottom of the lower section, which is to be kept, at least in part, flooded, where the conveyance assembly consists of a single-piece main part which has a "U" section incorporated, constituting a coaxial siphon-effect part. The present invention also relates to an apparatus installed in a liquid supply installation which incorporates in the conveyance assembly, or close to it, a system for measuring the characteristics of the liquid and its flow.
