Flat Sound Insulation Structure With Modular Cassette Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing noise protection constructions are time-consuming and costly to assemble due to the need for individual placement and fastening of sound insulation cassettes, which increases construction time and labor costs.
Innovation Solution
The development of plate-shaped, transportable cassette modules that combine multiple cassettes into a stable unit with a closed frame structure, allowing for quicker assembly and reduced construction time by grouping cassettes into modules that can be easily transported and installed as a single unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual cassettes are assembled and fastened separately, then the soundproofing structure can be constructed with modular components, but the construction time and labor costs increase significantly
Solution Approach 1:
Multiple individual cassettes are merged into a single integrated cassette module assembly that functions as one installable unit. The cassettes are connected to each other and to the support structure through a unified framework, allowing the entire assembly to be installed in one operation rather than individually fastening each cassette.
Solution Approach 2:
The cassettes are pre-assembled and pre-connected to the support structure in a factory or pre-construction setting, creating a ready-to-install module. This preliminary assembly includes attaching the cassettes to the framework and preparing all connection points before the module is transported to the installation site, eliminating on-site assembly time.
2Productivity
If multiple cassettes are combined into a single module, then construction time is reduced, but the structural complexity of the module increases
Solution Approach 1:
The cassette module is segmented into distinct functional components: the support framework, the individual cassettes, and the connecting elements. Each component has a specific function and can be independently manufactured, then assembled into the complete module. This segmentation allows for standardized production of parts while maintaining overall module functionality.
Solution Approach 2:
The support framework serves multiple functions simultaneously: it provides structural support for the cassettes, acts as a connection mechanism between cassettes, and integrates with the building structure. This multi-functionality reduces the number of separate components needed, simplifying the overall module design while maintaining assembly speed.
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
Significantly reduces construction time and costs by allowing for the assembly of multiple cassettes as a group, rather than individually, while maintaining effective noise protection and stability, and can be easily adapted for use as both walls and ceilings.

AI summary
The invention relates to a planar soundproofing construction (1) with supports (2) and cassettes (4) arranged side by side in parallel rows (3) between them, each cassette having a back (7) and a front (21) permeable to airborne sound and sound-absorbing material (33) arranged between the front (21) and the back (7), wherein both the supports (2) and the cassettes (4) as well as adjacent cassettes (4) are each closely connected to each other.To develop an alternative soundproofing structure characterized in particular by a short construction time, the present invention provides for plate-shaped cassette modules (9) that group a certain number of cassettes (4) together and each consist of an upper chord (10, 10'), a lower chord (11, 11'), and at least one row (3) of cassettes (4) extending between the upper chord (10, 10') and the lower chord (11, 11'), wherein the longitudinal axes (5) of the cassettes (4) are oriented perpendicular to a longitudinal axis (8) of the row (3) of cassettes (4), and the cassette modules (9) extend between at least two adjacent supports (2) and are attached to them. Furthermore, the present invention relates to a method for manufacturing a cassette module (9) and for assembling a soundproofing structure (1, 1').
