Vibration-Isolated Fastening Unit for Slotted Profile Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fastening units for sanitary fittings and other applications behind false walls face issues with noise and vibration due to the direct engagement of metal components, which can lead to unwanted noise and vibration transmission, particularly when securing pipes.
Innovation Solution
Incorporating a support element with a first layer of vibration isolating material on the underside of the washer element and a second layer on the upper side of the oblong anchoring element, providing a barrier against vibrations and enhancing clamping force when fastened to a profile element, using materials like elastomeric materials for optimal vibration isolation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal washer element and metal anchoring element directly engage the flanges of the profile element, then fire resistance and creep prevention are improved, but vibration and noise transmission increase
Solution Approach 1:
The patent introduces a support element with vibration isolating material as an intermediary between the metal washer element/anchoring element and the profile element flanges. This mediator allows the metal components to maintain their fire-resistant engagement while the vibration isolating material absorbs and dampens vibrations, preventing noise transmission. The support element acts as a buffer that decouples the rigid metal-to-metal contact path for vibrations while preserving the structural connection for fire safety.
Solution Approach 2:
The support element combines vibration isolating material with structural components to create a composite fastening system. The vibration isolating material (such as elastomeric materials) is integrated with the support element structure to form a composite assembly that provides both mechanical support and vibration damping. This composite approach allows simultaneous achievement of fire resistance (through metal components) and vibration isolation (through the elastomeric material).
2Strength
If metal components directly engage the profile element, then structural strength is improved, but noise generation increases
Solution Approach 1:
The support element with vibration isolating material serves as an intermediary that breaks the direct metal-to-metal contact path. The vibration isolating material absorbs impact forces and dampens vibrations generated by water flow through the pipe, converting mechanical vibration energy into heat through internal friction. This prevents the generation and transmission of noise while maintaining structural integrity through the combined metal-vibration isolating material system.
3Object-affected harmful factors
If vibration isolating material is added to the fastening unit, then noise and vibration are reduced, but device complexity increases
Solution Approach 1:
The patent merges the vibration isolating material with the support element structure to form an integrated assembly. Rather than adding separate vibration isolation components, the vibration isolating material is incorporated into the support element itself, creating a unified component that provides both structural support and vibration damping functions. This integration reduces the number of separate parts and simplifies assembly while achieving noise reduction.

AI summary
A fastening unit for fastening an object to a profile element includes a first layer of vibration isolating material arranged on an underside of a washer element and a second layer of vibration isolating material arranged on an upper side of an oblong anchoring element. The oblong anchoring element and the second layer of vibration isolating material each have a width that allows them, preferably in unity, to be aligned with a longitudinal slot of the profiled element inserted therein, and then turned to receive flanges of the profile element between the first layer of vibration isolating material and the second layer of vibration isolating material, so as to provide, at least in a fastened state of the fastening unit, a barrier for vibrations between the washer element and the flanges and between the oblong anchoring element and the flanges.
