Solution Overview
Problem
Existing pipe fixing devices fail to effectively attenuate vibration forces normal to the wall while ensuring a solid hold, often compromising between damping performance and mechanical strength, and are often costly and difficult to produce in a single material.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a double collar structure is used, then good damping performance is achieved, but cost increases, assembly becomes difficult, bulk increases, appearance becomes unattractive, and single-material production is not possible
Solution Approach 1:
The damping bridge is segmented into distinct functional zones: a collar portion for pipe attachment, a base portion for wall mounting, and an intermediate damping portion with cavities. This segmentation allows each zone to perform its specific function optimally while enabling single-material production through injection molding.
Solution Approach 2:
The damping bridge features nested cavities within the damping portion, creating a multi-chamber structure that provides vibration damping functionality. This nested design achieves the damping effect of complex structures while maintaining a compact form factor and enabling single-material manufacturing.
2Adaptability or versatility
If open collars are connected by a flexible bridge and bending elements, then connection flexibility is achieved, but both good damping and good mechanical strength cannot be ensured simultaneously
Solution Approach 1:
Different portions of the damping bridge have different structural qualities optimized for their specific functions: the collar and base portions have higher rigidity for mechanical strength, while the intermediate damping portion has cavities for vibration absorption. This local differentiation achieves both flexibility and strength simultaneously.
3Adaptability or versatility
If a damping bridge with two deformable rings is used, then deformation in all directions is possible, but the device cannot withstand heavy loads without excessive deformation
Solution Approach 1:
The damping bridge has localized damping cavities in the intermediate portion while maintaining rigid collar and base sections. This allows controlled deformation for vibration damping while preserving load-bearing capacity for heavy loads.
4Ease of operation
If curved lips are used in elastomeric material, then easy deformation is achieved, but lateral and angular deformation occurs easily
Solution Approach 1:
The damping bridge has a rigid overall structure with localized damping cavities, providing structural stability while allowing controlled local deformation for vibration absorption. This prevents excessive lateral and angular deformation.
