Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing acoustic panels are complex and costly to produce, with a multi-layer structure that requires precise mounting and is not easily adaptable for offset-free, visually appealing surfaces, making them inefficient for room acoustics improvement.
Innovation Solution
An acoustic panel design featuring a base plate with locking profiles for adhesive-free connection and a multiplicity of recesses that penetrate through the base plate to an absorber unit, allowing for easy assembly and sound wave absorption without offset, using a wood-based material board with a cover layer and absorber unit for effective sound absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If acoustic panels use a multi-layer structure with perforations and separate absorber surfaces, then sound absorption efficiency is improved, but structural complexity and production cost increase
Solution Approach 1:
The patent combines the base plate and absorber unit into a single integrated acoustic panel component. The absorber unit is directly attached to the base plate, eliminating the need for separate mounting of absorber materials. This merging reduces structural complexity while maintaining sound absorption efficiency through the integrated design.
Solution Approach 2:
The patent uses a base plate with multiplicity of recesses (perforations) that allow sound waves to penetrate into the absorber unit. The porous structure of the base plate with its multiple recesses enables effective sound absorption while maintaining a simpler overall structure compared to traditional multi-layer perforated panels.
2Ease of operation
If acoustic panels are designed as independent components for separate attachment, then installation flexibility is improved, but mounting precision and visual alignment deteriorate
Solution Approach 1:
The patent incorporates locking profiles on the longitudinal sides and end faces of the base plate that enable self-aligning connection between adjacent acoustic panels. The locking profiles automatically ensure proper positioning and visual alignment when panels are installed, eliminating the need for precise manual positioning while maintaining installation flexibility.
3Reliability
If acoustic panels use complex structural designs for high efficiency, then sound absorption performance is improved, but production cost and manufacturing complexity increase
Solution Approach 1:
The patent segments the acoustic panel into two main functional parts: a base plate with locking profiles and a separate absorber unit. This segmentation allows for simplified manufacturing of each component independently using standard wood-based materials, reducing production costs while maintaining effective sound absorption through the integrated assembly.
Solution Approach 2:
The patent uses composite construction with a wood-based material board for the base plate and separate absorber material attached to it. This composite approach allows optimization of each material for its specific function while keeping overall production costs lower than using complex homogeneous structures.
4Strength
If acoustic panels require adhesive connection for assembly, then connection strength is improved, but installation complexity and time increase
Solution Approach 1:
The patent replaces adhesive chemical bonding with mechanical interlocking through locking profiles on the longitudinal sides and end faces. The locking profiles enable mechanical connection between adjacent panels through click-in or interlocking mechanisms, providing sufficient connection strength while eliminating the complexity and time requirements of adhesive application and drying.

AI summary
The invention relates to an acoustic panel for use as ceiling and wall covering, comprising a base plate, at least one wood-based panel with a top and a bottom surface and a top layer arranged on the top surface, an absorber unit arranged on the bottom surface for absorbing room sound, and a plurality of recesses completely penetrating the base plate for directing room sound striking the top surface of the panel into the absorber unit. To provide a structurally simple and cost-effective acoustic panel with which seamless and visually appealing surfaces can be created, it is provided that corresponding locking profiles are arranged on the longitudinal sides and/or end faces of the base plate for adhesive-free connection with further acoustic panels.
