Building Stud Vibration Isolation With Resilient Fastener Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound reduction methods and devices are inadequate in effectively reducing vibration transmission between building components, particularly between a building stud and other members, which can lead to unwanted noise and structural instability.
Innovation Solution
A vibration reducing system that includes a vibration mat with a resilient member and a fastener, where the resilient member is interposed between the building stud and the fastener to absorb vibrations, and a rigid sleeve limits the compression of the mat and resilient member, ensuring effective vibration isolation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a fastener directly secures the building stud to the member, then the structural strength is improved, but the vibration transmission increases
Solution Approach 1:
The patent introduces a resilient member as an intermediary element between the fastener and the building stud. This resilient member absorbs and dampens vibrations while still allowing the fastener to secure the structural connection, thus resolving the contradiction between maintaining structural strength and reducing vibration transmission.
Solution Approach 2:
The patent employs a composite assembly consisting of multiple materials with different properties: a rigid fastener for structural strength, a resilient member for vibration absorption, and a vibration mat for additional damping. This composite structure allows simultaneous achievement of both structural integrity and vibration reduction.
2Object-generated harmful factors
If a resilient member is added between the fastener and building stud, then the vibration transmission is reduced, but the device complexity increases
Solution Approach 1:
The patent combines multiple vibration reduction functions into a single integrated resilient member that performs both vibration absorption and shock damping. This merging of functions reduces the overall complexity compared to using separate components for each function.
Solution Approach 2:
The resilient member is designed to serve multiple purposes: it acts as a vibration absorber, a shock damper, and a stress distributor. This multi-functionality eliminates the need for multiple separate components, thereby reducing device complexity while still achieving vibration reduction.
3Object-generated harmful factors
If the vibration mat is compressed to improve vibration isolation, then the vibration reduction effectiveness is improved, but the structural stability may be compromised
Solution Approach 1:
The patent employs a resilient member that dynamically adjusts its compression based on the applied load and vibration frequency. Under normal structural loads, it maintains sufficient compression for vibration isolation, but automatically adjusts to prevent excessive compression that would compromise structural stability.
Solution Approach 2:
The resilient member's physical parameters (such as stiffness and damping coefficient) are carefully selected to change with compression level. At low compression levels, it provides effective vibration isolation, while at higher compression levels, it becomes stiffer to maintain structural stability, thus resolving the contradiction between vibration reduction and structural stability.

Function Achieved in This Case
The system significantly reduces vibration transmission between building components, enhancing sound insulation and structural stability by decoupling the building stud from other members, thereby minimizing noise and vibration-related issues.
