Floor Covering Element With Acoustic Decoupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor covering elements often fail to create a flat surface due to unevenness in underlying construction levels, leading to tilting and wobbling, and suffer from high sound conductivity, causing discomfort and noise transmission in living and working spaces.
Innovation Solution
The floor covering element features a base plate acoustically decoupled from the subsurface with a soundproofing part made of porous mineral building materials, such as single-grain granules or foam glass, which dampens sound vibrations and provides improved thermal insulation, and is designed with feet that allow for leveling and stable support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid floor covering elements are used, then structural stability is improved, but sound insulation deteriorates due to high sound conductivity through the rigid structure
Solution Approach 1:
The base is constructed as a composite structure combining rigid mineral granules for structural stability and porous foam glass beads for sound insulation. This composite material approach allows simultaneous achievement of mechanical strength and acoustic performance by integrating materials with complementary properties within the same base structure.
Solution Approach 2:
The base exhibits spatially varying properties: regions with higher mineral granule concentration provide structural support, while regions with higher foam glass content provide sound insulation. This local differentiation of material composition allows the base to perform multiple functions simultaneously in different zones.
2Force
If the base plate is directly supported on the subfloor, then structural support is improved, but surface flatness deteriorates due to subfloor unevenness causing tilting and wobbling
Solution Approach 1:
The base is designed as a deformable element that can adapt its shape and position in response to subfloor irregularities. The porous foam glass structure allows controlled deformation and settling, enabling the base plate to achieve a level position while maintaining structural support function.
Solution Approach 2:
The porous foam glass beads in the base provide built-in cushioning capacity that absorbs and compensates for subfloor unevenness before the base plate settles into its final position. This pre-cushioning effect prevents tilting and ensures flat surface alignment.
3Stability of the object's composition
If rigid connection between floor covering elements and subfloor is used, then structural stability is improved, but horizontal shifting is prevented, but sound transmission is increased
Solution Approach 1:
The porous foam glass base acts as an intermediary element between the rigid base plate and the subfloor. It provides mechanical connection stability while acoustically decoupling the structure-borne sound path through its sound-absorbing properties.
