Flexible Pipe Cuff With Pocket Guide For Tool-Free Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of flexible connections for loss-in-weight scales in metal piping systems is often error-prone due to the need for skilled installation, time pressure, and adverse working conditions, leading to inaccurate and unsafe operation.
Innovation Solution
A flexible sleeve with an inner diameter matching the metal pipe's outer diameter, featuring a pocket for an axially acting pressure element that provides a dust-tight seal and centering, allowing tool-free connection and disconnection, and optionally incorporating a bellows to prevent force shunts, with a magnetic coupling for reliable sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional flexible sleeves are installed on metal pipes, then connection between pipes is achieved, but assembly errors occur due to complex installation requirements and lack of guidance
Solution Approach 1:
The sleeve is pre-formed with an integrated pocket structure that guides the pressure element into the correct position during assembly. The pocket is pre-positioned at a specific distance from the edge, ensuring proper alignment without requiring complex installation procedures or expert skill.
Solution Approach 2:
The pocket acts as an intermediary structure between the sleeve and the pressure element. It guides the pressure element into the correct position and maintains the required distance from the pipe end, preventing assembly errors while simplifying the installation process.
2Reliability
If flexible connections are designed for secure sealing, then dust-tight connection is achieved, but assembly and disassembly require tools and time
Solution Approach 1:
The pressure element automatically centers itself within the pocket during assembly through the pocket's guiding geometry. The sleeve's edge provides a stop that automatically positions the assembly at the correct location, eliminating the need for tools or complex alignment procedures.
3Reliability
If the pressure element is integrated into the sleeve structure, then sealing is improved, but manufacturing complexity increases
Solution Approach 1:
The sleeve is designed with a distinct pocket segment that is integrated into the sleeve body. This segmentation allows the pressure element to be held in a dedicated compartment, improving sealing reliability while keeping the overall structure relatively simple through the use of a single molded piece.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates quick, tool-free assembly and disassembly by inexperienced personnel, ensuring accurate and safe operation even under adverse conditions, while minimizing the risk of assembly errors and force shunts.
Implementation Method 1
The powerful magnetic coupling of the permanent magnets to the end section of the metal pipe achieves a very reliable, dust-tight sealing effect of the sleeve with the metal pipe.
