Guide Rail Holder With Pivot Connection For Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional guide rail assemblies for submersible machines experience material fatigue and risk of guide rail ends splitting due to rigid connections, which lead to wear and vibration issues in the wall connections.
Innovation Solution
A guide rail holder with a radially expandable member that can be reversibly manipulated between active and inactive states, allowing for a flexible connection between the guide rail and holder, reducing stress and enabling vibration damping, and featuring an engagement head positioned away from the guide rail end to prevent splitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid connection is used between the guide rail and guide rail holder, then the connection is stable and secure, but the guide rail ends experience great stress and risk to split open due to forces and bending moments
Solution Approach 1:
The guide rail holder is designed with a pivot connection that allows the guide rail to rotate dynamically relative to the holder, transforming the rigid static connection into a dynamic one. This enables the system to adapt to forces and bending moments by rotating at the pivot point, preventing stress concentration at the guide rail ends while maintaining connection stability.
Solution Approach 2:
The invention changes the connection parameter from rigid fixed to pivoting rotational, allowing the guide rail to change its angular position relative to the holder. This parameter change enables the system to accommodate varying loads and bending moments without compromising the strength of guide rail ends.
2Stability of the object's composition
If a rigid connection is used between the guide rail and guide rail holder, then the connection is stable, but material fatigue occurs and the wall is worn out and shredded
Solution Approach 1:
The pivot connection introduces dynamic movement capability, allowing the guide rail to rotate and absorb pulsating forces generated during mixer operation. This dynamic adaptation prevents the rigid stress transfer that causes material fatigue and wall wear, while maintaining stable operational connection.
Solution Approach 2:
The pivot connection acts as a cushioning mechanism that absorbs and dissipates pulsating forces before they can transfer to the wall structure. By providing this beforehand cushioning, the system prevents material fatigue and wall damage while maintaining connection stability.
3Stability of the object's composition
If a rigid connection is used, then the guide rail is securely held, but vibrations generated during operation are not dampened
Solution Approach 1:
The pivot connection creates a dynamic joint that can rotate to accommodate vibrational movements. This dynamic capability allows the system to dampen vibrations generated during mixer operation while maintaining secure guide rail positioning, as the pivot absorbs vibrational energy through controlled rotation.
4Manufacturing precision
If tight tolerances are required for guide rail assembly, then precise alignment is achieved, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The pivot connection provides inherent alignment tolerance by allowing rotational adjustment during assembly. This dynamic feature enables installers to accommodate misalignments and tolerance variations without requiring complex adjustment mechanisms, simplifying the assembly process while achieving proper alignment.
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 increased structural flexibility to absorb bending moments, reduces material fatigue, and effectively dampens vibrations, preventing guide rail ends from splitting and minimizing wall wear.
Implementation Method 1
a radially expandable member (16) that is adapted to be reversibly manipulated between an active state, in which the expandable member (16) is in engagement with the guide rail (4), and an inactive state, in which the expandable member (16) is disengaged from the guide rail (4)
Implementation Method 2
It is another object of the present invention to provide a guide rail holder that dampen vibrations generated during operation in the entire guide rail assembly and especially in the guide rail holder

AI summary
A guide rail assembly for a submersible machine as well as a guide rail holder for such a guide rail assembly is described herein. The guide rail holder includes a radially extending support body and an axially extending post, which is rigidly connected to the support body and which is adapted to be inserted into an end of the guide rail. An engagement head is connected to the post at a distance from the support body and has a greater radial extension than the post. The engagement head includes a radially expandable member that is adapted to be reversibly manipulated between an active state, in which the expandable member is in engagement with the guide rail, and an inactive state, in which the expandable member is disengaged from the guide rail.
