Solution Overview
Problem
Existing sound absorbers for walls and ceilings lack simplicity in design and flexibility in accommodating varying material thicknesses, limiting their adaptability and functionality.
Innovation Solution
A sound absorber design featuring a circular opening sound absorber plate, a tube with external thread and flange, a mounting ring with internal thread, and a holding device that allows for flexible mounting on walls or ceilings, with optional features like a second mounting ring for suspended ceilings and integrated lighting, accommodating different material thicknesses and providing adjustable installation options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sound absorber uses a fixed mounting structure, then the installation is simple, but it cannot accommodate varying material thicknesses (10-60 mm)
Solution Approach 1:
The mounting structure incorporates an adjustable mechanism that allows dynamic adaptation to different material thicknesses. The mounting element can be positioned at various heights along the tube, enabling the sound absorber to accommodate material thicknesses ranging from 10-60 mm while maintaining a relatively simple overall structure.
Solution Approach 2:
The mounting system allows for parameter adjustment in terms of vertical position to accommodate varying material thicknesses. By changing the mounting position parameter along the tube length, the system adapts to different absorption material thicknesses without requiring complete structural redesign.
2Adaptability or versatility
If a sound absorber is designed with multiple mounting options and adjustable features, then it becomes highly adaptable to different installations, but the device complexity increases
Solution Approach 1:
The mounting system is designed to serve multiple functions: it can accommodate different material thicknesses, support various installation positions (wall or ceiling mounting), and provide stable fixation. This multi-functionality is achieved through a relatively simple tube-based structure with an adjustable mounting element, avoiding excessive complexity while maintaining high adaptability.
3Reliability
If a sound absorber uses a simple mounting structure, then the device complexity is low, but the reliability of secure mounting varies material thicknesses is poor
Solution Approach 1:
The mounting element can be dynamically positioned along the tube to ensure reliable engagement with the support surface regardless of material thickness. This dynamic adjustment capability ensures secure mounting by allowing the mounting element to engage at the optimal position, providing reliable fixation while keeping the overall structure relatively simple.

Function Achieved in This Case
The solution provides a simple, adaptable sound absorber that can be easily mounted on various thicknesses of materials, offering effective sound absorption and the option to incorporate lighting, enhancing both functionality and versatility.
Implementation Method 1
a tube with two tube ends, with an external thread and with an external flange protruding radially outwards, a first mounting ring with an internal thread
Implementation Method 2
the sound absorber plate is fitted with its opening onto the tube and clamped between the outer flange of the tube and the first mounting ring screwed onto the external thread
Implementation Method 3
the holding device has a mounting element to be fastened to the wall or ceiling, which is inserted into the interior of the tube and, viewed in the direction from the end of the tube facing away from the ceiling or wall towards the end of the tube facing the ceiling or wall, has an inner shoulder of the tube grips behind
Implementation Method 4
Sound absorbers mounted on the wall or ceiling are well known and serve to enable sound absorption of airborne noise. Sound waves are absorbed by the sound absorbers made of e.g. porous materials or fibrous absorption materials
Implementation Method 5
Sound waves are absorbed by the sound absorbers made of e.g. porous materials or fibrous absorption materials
