Pipeline Joint Stabilizing Mechanism for Vibration Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipeline connection technologies fail to effectively compensate for manufacturing tolerances and changes caused by vibration or temperature, leading to instability and misalignment between pipeline sections.
Innovation Solution
A connecting device featuring a stabilizing joint with movably connected retaining plates and flexible connecting rods, combined with a compensator flange and flexible connection components like corrugated tubes or hoses, allows for flexible and secure attachment to pipeline sections, enabling movement and alignment adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If pipeline sections are rigidly connected to compensate for manufacturing tolerances and dimensional changes, then alignment stability is improved, but flexibility to accommodate vibration and temperature changes deteriorates
Solution Approach 1:
The connecting device is divided into distinct functional components: a compensator for absorbing dimensional changes and a stabilizing joint for maintaining alignment. This segmentation allows each component to specialize in one aspect of the contradiction - the compensator provides flexibility while the stabilizing joint provides stability.
Solution Approach 2:
The stabilizing joint acts as an intermediary between the flexible compensator and the rigid pipeline sections. It mediates between the need for flexibility (from the compensator) and the need for stability (for pipeline alignment), allowing movement while maintaining proper orientation.
2Adaptability or versatility
If a compensator is used to provide flexible connection between pipeline sections, then adaptability to dimensional changes is improved, but stability and alignment maintenance deteriorates
Solution Approach 1:
The invention merges two previously separate functions into a single integrated connecting device: the compensator for flexibility and the stabilizing joint for alignment stability. This combination allows the system to simultaneously achieve both adaptability and stability that were previously contradictory.
Solution Approach 2:
The connecting device serves multiple functions simultaneously: it compensates for manufacturing tolerances, accommodates thermal expansion and vibration, and maintains pipeline alignment. This multi-functionality resolves the contradiction by making the system capable of both flexibility and stability.
3Strength
If connecting rods are rigidly mounted to retaining plates, then structural stability is improved, but ability to accommodate movement and vibration deteriorates
Solution Approach 1:
The connecting rods are designed with flexible mounting through bearings instead of rigid fixation. This dynamic mounting allows the connecting rods to maintain structural stability while accommodating movements caused by vibration and temperature changes, resolving the contradiction between strength and adaptability.
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
The solution provides a stable and flexible connection that compensates for tilting and length changes in pipeline sections without altering the alignment of connected sections, ensuring reliable and secure attachment through screw connections or welding.
Implementation Method 1
The connecting rods are each flexibly mounted with a first rod end in a bearing of the first retaining plate and with a second rod end in a bearing of the second retaining plate

AI summary
The device has a compensator (9) for flexible connection of pipe line portions (1, 2), and a stabilization joint (10) comprising a support plate (15) i.e. angle connector, fastened with one of the pipe line portions and another support plate (16) fastened with the other pipe line portion. The support plates are movably connected with one another by two tie bars (17). Each bar end (22) in a bearing (20) of the former plate and another bar end in a bearing of the latter plate are arranged orthogonal to a connecting direction and parallel to each other on different sides of the compensator.
