Floor Panel with Nested Recesses for Acoustic Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor panels lack effective sound-absorbing properties, which are essential for reducing noise and improving speech intelligibility in rooms, particularly in spaces like concert halls and recording studios.
Innovation Solution
The floor panel design features a wood-based carrier board with a groove and tongue profile, incorporating a large number of recesses with small upper sections and larger lower sections, where the upper sections have a cross-sectional area that prevents liquid penetration and are designed to open into large cavities, enhancing sound absorption. Additionally, blind holes can be included to simplify production and appearance, with a final layer of acoustic fleece and porous material for improved sound insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cross-sectional area of upper sections is reduced to prevent liquid entry, then ease of operation is improved, but sound absorption deteriorates
Solution Approach 1:
The recesses are designed as nested structures where the smaller upper section is positioned within the larger overall recess structure, allowing the small opening to serve as a protective barrier while the larger lower section provides the volume needed for sound absorption
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
This design significantly improves sound absorption, reduces noise, and maintains panel stability while protecting against moisture and dirt, making it suitable for high-traffic areas with minimal visual impact.
Implementation Method 1
for each recess the cross-sectional area of each upper section is smaller than the cross-sectional area of the lower section
Implementation Method 2
Floor panel with sound-absorbing properties containing a support plate with a large number of recesses
