Coaxial Nested Tubes for Stable Container Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for filling and emptying containers, particularly liquid containers, are unstable due to inadequate connection methods, leading to potential bending or twisting of tubes and complications in assembly and manufacturing.
Innovation Solution
A device featuring tubes of different diameters, where the smaller diameter tube is coaxially arranged within the larger diameter tube, with a fastening device and connecting piece to enhance stability, and a centering ring to secure the lower ends, allowing for secure fitting into container openings and uniform material flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If two tubes are connected parallel using clamps, then the device structure is simple, but the stability is poor and tubes can twist or bend
Solution Approach 1:
The patent applies nesting by placing one tube inside the other tube, forming a concentric arrangement where the smaller diameter tube is positioned within the larger diameter tube. This nested configuration provides mutual support between the tubes, preventing twisting and bending while maintaining structural simplicity without requiring additional complex fastening mechanisms.
2Ease of manufacture
If tubes are arranged parallel with clamps, then assembly is simple, but the tubes can bend and twist causing instability
Solution Approach 1:
The nested tube arrangement simplifies manufacture by eliminating the need for complex clamp assemblies and alignment mechanisms. The tubes are simply inserted one into the other, providing both ease of manufacturing and enhanced stability through the self-supporting concentric structure.
3Device complexity
If tubes are arranged parallel, then the structure is simple, but the upper ends can bend causing instability
Solution Approach 1:
By nesting the tubes concentrically, the upper ends of both tubes are supported by each other, preventing bending and twisting. This maintains low device complexity while significantly improving stability at the vulnerable upper end regions.
4Manufacturing precision
If tubes of different diameters are arranged coaxially, then uniform delivery is achieved, but the device complexity increases
Solution Approach 1:
The coaxial nested arrangement of tubes with different diameters naturally provides uniform delivery characteristics while maintaining relatively simple device structure. The concentric positioning ensures symmetric flow paths and uniform material distribution without requiring additional complex guiding or centering mechanisms.

AI summary
The device (10) has a pipe (20) for inflow and reflux which is fixed in a fixing device. The pipe has a diameter (d1) larger than the other pipe (30) which has a smaller diameter (d2). The pipe with the smaller diameter is coaxially arranged in the pipe with the larger diameter. The pipe with smaller diameter is longer than the pipe with larger diameter. An independent claim is included for application of device.
