Suspended Sound Absorption Element for Sanitary Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sanitary installation systems face increased installation time due to the need for filling cavities with sound absorption materials like mineral wool, which also poses technical disadvantages if overfilled.
Innovation Solution
A sanitary installation system with a mounting structure and a cavity that includes a freely hanging sound absorption element suspended using a fastening unit with an upper and lower support element and a connecting element, allowing for flexible assembly and reduced component count, with the sound absorption element designed as a determinate body for easier handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the cavity is filled with mineral wool or flake material for sound insulation, then sound insulation is improved, but installation time increases significantly
Solution Approach 1:
The sound absorption function is segmented from the filling process. Instead of filling the entire cavity with loose material, discrete sound absorption elements are suspended at specific locations within the cavity using fastening units, dividing the sound insulation task into targeted segments rather than requiring complete cavity filling
Solution Approach 2:
The sound absorption elements are extracted from the cavity filling concept and suspended freely within the cavity space. This removes the need to fill the cavity with material while maintaining sound absorption functionality through strategically positioned hanging elements
2Object-affected harmful factors
If too much mineral wool or flake material is pressed into the cavity, then sound insulation is improved, but technical disadvantages occur
Solution Approach 1:
The sound absorption capability is segmented into multiple discrete elements rather than requiring a large volume of filling material. These individual elements can be independently positioned and secured, avoiding the complexity of managing excessive filling material
Solution Approach 2:
The sound absorption elements are designed to be self-sufficient units that can be individually fastened to the mounting structure. Each element serves its sound absorption function independently without requiring additional material or complex assembly procedures
3Ease of operation
If freely hanging sound absorption elements are used, then installation is simplified, but the number of components increases
Solution Approach 1:
The fastening unit combines multiple components (upper support element, lower support element, connecting element) into an integrated assembly mechanism. This merging allows the sound absorption element to be suspended as a unified unit, simplifying installation while managing component count through functional integration
