Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe fastening devices fail to effectively decouple radial vibrations from pipes, leading to significant transmission of structure-borne noise into adjacent spaces due to compression of shock-absorbing interlayers, which reduces their soundproofing efficacy.
Innovation Solution
A pipe fastening device utilizing a conical, flexible connecting element between a fixing clamp and a bearing clamp, with the bearing clamp surrounding the pipe and the fixing clamp supported by this element, preventing direct contact and allowing for automatic centering, thereby reducing radial vibration transmission. The connecting element is made of a rubber-like material, and the clamps consist of rigid half-elements with elastomer inserts for enhanced sound insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the pipe clamp is clamped tightly around the pipe to prevent dropping, then the pipe is securely fastened, but the intermediate layer is compressed and sound insulation becomes insufficient
Solution Approach 1:
The patent introduces a conical connecting element made of flexible material as an intermediary between the fixing clamp and bearing clamp. This connecting element acts as a mediator that decouples the mechanical connection while maintaining sound insulation, preventing direct contact between the clamps and eliminating the need for compression of the intermediate layer for fastening strength.
Solution Approach 2:
The conical connecting element is made of flexible material that can deform to accommodate installation tolerances and pipe position variations. This flexibility allows the clamps to be securely fastened without requiring tight compression, thereby maintaining the sound insulation properties of the intermediate layer.
2Strength
If the pipe clamp is clamped tightly to ensure secure fastening, then the pipe cannot drop, but radial vibrations are transmitted into the masonry
Solution Approach 1:
The conical connecting element serves as a flexible intermediary that breaks the direct mechanical path for vibration transmission. By introducing this flexible element, the patent decouples the vibration path while maintaining the fastening function, preventing radial vibrations from being transmitted into the masonry.
Solution Approach 2:
The patent changes the mechanical parameters of the connection by introducing a flexible conical element with specific geometric and material properties. This parameter change allows the connection to maintain strength while reducing vibration transmission through the flexible deformation characteristics of the connecting element.
3Device complexity
If conventional clamps are used with direct contact between clamp elements, then the structure is simple, but sound insulation effectiveness varies with installation precision
Solution Approach 1:
The conical connecting element provides self-aligning and self-adjusting properties that automatically compensate for installation imprecisions. The conical geometry allows the element to self-center and distribute forces evenly, making the sound insulation effectiveness independent of installation precision while maintaining structural simplicity.
Solution Approach 2:
The flexible conical connecting element introduces dynamic deformation capabilities to the otherwise static clamp structure. This dynamic property allows the connection to adapt to various installation conditions and pipe positions, ensuring consistent sound insulation performance regardless of installation precision.

Function Achieved in This Case
The solution effectively decouples radial vibrations and enhances soundproofing by minimizing contact between the pipe and the wall, ensuring consistent sound insulation regardless of installation precision, and allowing for cost-effective manufacturing processes.
Implementation Method 1
The two clamps are connected by means of at least one conical flexible and/or pliable and/or elastic connecting element
Implementation Method 2
Tests have shown that radial vibrations in a pipe run are introduced into the masonry via the pipe attachment and radiated into the neighboring room
