Viscoelastic Structural Connector for Load-Bearing Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration damping and soundproofing solutions in building construction are not structurally capable of supporting large or complex loads and fail to effectively resist significant forces, and existing soundproofing methods are costly and primarily surface-based, lacking integration into structural elements.
Innovation Solution
A structural connector comprising two opposing sheets bonded with a solid piece of visco-elastic sound-attenuating vibration damping material, where the sheets have extended portions for attachment and channels for the damping material, preventing interlocking and allowing for reinforcement, enabling the connector to absorb and dissipate vibrations while supporting building elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If composite vibration dampers are used for soundproofing, then vibration damping is achieved, but they cannot support large or complex loads or resist significant forces
Solution Approach 1:
The patent merges vibration damping functionality with structural load-bearing capacity by integrating a viscoelastic polymeric layer between two steel sheets, creating a composite connector that simultaneously dampens vibrations and supports building loads
Solution Approach 2:
The patent uses composite materials consisting of steel sheets bonded to a viscoelastic polymeric layer, combining the high strength and rigidity of steel with the vibration damping properties of the polymeric material to achieve both structural support and soundproofing
2Object-affected harmful factors
If substantial insulation and specially designed building materials are used for soundproofing, then sound attenuation is improved, but cost increases and installation becomes difficult
Solution Approach 1:
The patent combines soundproofing functionality with structural connection elements into a single integrated component, eliminating the need for separate insulation materials and simplifying installation while maintaining effective sound attenuation
