Cork-Filled Lacquer Composite for Walking Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flooring and furniture materials do not effectively reduce unwanted noise, leading to disturbances within and between rooms, and require additional sound insulation layers, complicating installation.
Innovation Solution
A composite element with a substrate, a lacquer layer containing cork powder, and a top layer is used to dampen sound, eliminating the need for separate sound insulation layers and simplifying installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional flooring materials are used, then the installation process requires additional separate sound insulation layers, but this increases device complexity and installation time
Solution Approach 1:
The patent combines the sound insulation function with the flooring material itself by incorporating cork powder into the lacquer layer. This merging of functions eliminates the need for separate sound insulation layers, reducing the total number of layers from multiple separate components to an integrated composite structure, thereby simplifying the installation process and reducing installation time
2Productivity
If traditional flooring materials are used, then the structure is simpler, but this results in increased installation time due to additional sound insulation layers
Solution Approach 1:
By integrating the sound insulation function into the lacquer layer through cork powder incorporation, the patent eliminates the need to install separate sound insulation layers beneath the flooring. This reduces the number of installation steps and materials required, directly decreasing installation time and improving productivity despite the enhanced composite structure
3Object-affected harmful factors
If conventional materials are used, then the material composition is simpler, but this fails to reduce unwanted noise effectively
Solution Approach 1:
The patent employs a composite material system where cork powder particles are dispersed within a lacquer matrix. This composite structure combines the sound-absorbing properties of cork with the binding and protective properties of lacquer, creating a material that effectively reduces unwanted noise from foot traffic and objects while maintaining a relatively simple overall composition suitable for flooring applications
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 composite element effectively reduces walking and impact noise, enhancing room comfort and reducing installation time by integrating sound reduction directly into the material.
Implementation Method 1
the sound is transferred from the top layer to the lacquer layer and dampened by the cork powder embedded in the lacquer
Implementation Method 2
the lacquer layer, in combination with the cork powder, reduces the noise produced when the composite element is used
