Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening methods for furniture fail to effectively dampen structure-borne sound and vibrations across various building types, particularly when installation instructions are not followed, leading to noise emissions and non-compliance with vibration attenuation standards.
Innovation Solution
A fastening part with elastomer inserts and supports that decouple the furniture from the building structure, using elastomer-lined holes and guide sleeves to absorb vibrations and sound, ensuring effective damping and compliance with standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If special anchors are used to dampen sound transmission, then vibration attenuation is improved, but installation complexity increases and reliability decreases when instructions are not followed
Solution Approach 1:
The patent introduces an intermediate fastening part with elastic material between the furniture and the building structure. This intermediary component absorbs vibrations and dampens sound transmission without requiring precise installation procedures, thereby resolving the contradiction between effective sound dampening and ease of installation.
Solution Approach 2:
The patent changes the physical parameters of the fastening system by incorporating elastic material that can deform under load. This parameter change allows the fastening part to adapt to different installation conditions while maintaining vibration attenuation, thus improving both sound dampening and installation ease.
2Object-affected harmful factors
If special anchors are used for vibration attenuation, then sound transmission is reduced, but adaptability to different building types decreases
Solution Approach 1:
The fastening part is designed with universal applicability to work with different building wall types. The elastic material and modular design allow it to function effectively across various building materials and structures, thereby achieving both vibration attenuation and broad adaptability.
Solution Approach 2:
The elastic material's ability to change physical parameters under different loading conditions enables the fastening part to adapt to various building types while maintaining consistent vibration attenuation performance.
3Strength
If rigid fastening is used to securely attach furniture, then connection strength is improved, but vibration transmission increases
Solution Approach 1:
The fastening part combines rigid structural components with elastic damping material to create a composite system. This composite structure maintains connection strength while the elastic component absorbs vibrations and reduces structure-borne sound transmission.
Solution Approach 2:
The elastic material acts as an intermediary between the rigid fastening components, decoupling the strength transmission from vibration transmission. This allows the connection to remain strong while preventing the propagation of structure-borne sound.
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 at least 3 dB reduction in sound transmission, with optimal conditions showing up to 14.2 dB reduction, effectively addressing noise emissions and meeting regulatory standards.
Implementation Method 1
the at least one hole for the fastening means towards the building and/or the provisions (at least one hole, support surfaces) for attachment to the furnishing item can be equipped with an elastic material in order to introduce damping into the transmission chain
Implementation Method 2
introduce damping into the transmission chain from the interior furnishing item via the fastening part and the fastening means into the building wall

AI summary
For interior furnishings (15), e.g. kitchen cabinets or floor-standing kitchen modules, there are specific requirements to prevent the transmission of structure-borne sound, e.g. to avoid sound emissions via the building wall. The transmission of structure-borne sound is dampened by installing at least one damping insert (25; 41) and, if appropriate, external damping layers (17) in a fastening part (3). The fastening part (3) has at least two types of holes, namely a hole (11) for the fastening means towards the building and one or more holes (21) for fastening to the furnishing, of which at least one of the holes of the first and second type is equipped with a damping insert made of an elastomer in order to prevent the transmission of structure-borne sound between a fastening means, such as a screw, in the hole to the fastening part.
