Floating Floor Vibration Damping via Discrete Elements and Strip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floating floors are specifically designed for particular activities and impact energy levels, making them less suitable for other applications, and often require mechanical fastening which can lead to vibration and noise transmission.
Innovation Solution
A floating floor system with a support slat and discrete vibration-damping elements, combined with a vibration-damping strip that extends along the slat's length, allowing the floor to rest on the strip and elements without direct contact with the underground, providing universal vibration and noise damping across a wide range of impact energy levels and loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If floating floors are specifically designed with adapted static and dynamic rigidnesses for a specific activity, then the vibration and noise damping is sufficient for that specific application, but the floor becomes less suitable for other applications and activities
Solution Approach 1:
The support slat is designed to provide universal vibration and noise damping across multiple activities and impact energy levels. By incorporating discrete vibration-damping elements distributed along the slat, the system achieves multi-functionality that works effectively for various sports activities without requiring activity-specific customization.
2Strength
If the floating floor is mechanically fixed to support slats by means of screws, then the floor is securely attached, but vibrations and noise are transmitted between the floor and support structure
Solution Approach 1:
Discrete vibration-damping elements are introduced as intermediary components between the floor and support slat. These elements serve as mediators that decouple the mechanical connection while providing vibration and noise damping, eliminating the harmful effects of direct mechanical fastening.
3Reliability
If discrete vibration-damping elements are distributed at regular intervals along support slats, then efficient vibration damping is achieved for specific applications, but the construction complexity increases
Solution Approach 1:
The vibration-damping characteristics are optimized by adjusting parameters such as the distribution pattern, spacing, and physical properties of the discrete vibration-damping elements. This allows efficient vibration damping to be achieved while maintaining a relatively simple and practical construction approach.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution achieves improved vibration and noise damping with reduced friction and increased stability, allowing the floor to move freely and maintain comfort and reduce damage from vibrations across various activities without the need for mechanical fastening, while minimizing the building height and material usage.
Implementation Method 1
discrete vibration-damping elements distributed across the support slat at a distance from one another
Implementation Method 2
Thanks to an elastic deformation of the elements and the strip, the support slat can move in relation to the floor and the underground
