Transportable Sound Absorbing Wall With Self-Supporting Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transportable sound-absorbing walls face issues with separate transportation of foam panels and stand rods, which are bulky and unstable, reducing the effectiveness of sound absorption due to reflection of sound on support frames.
Innovation Solution
A transportable sound-absorbing wall composed of individual panels with a stable, surrounding frame and sound-absorbing plates that enclose vertical support frame sections, allowing for easy assembly and self-supporting configuration without external rods, using a transport case with rollers and handles for efficient handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If foam panels and stand rods are transported separately, then the sound absorbing wall can be assembled from individual components, but the stand rods become bulky and unstable for transport
Solution Approach 1:
The patent merges the foam panel and support frame into a single integrated unit where the foam panel is directly attached to the support frame. This eliminates the need for separate transport of foam panels and stand rods, while maintaining the ability to assemble multiple units into a complete sound absorbing wall. The integrated design provides structural stability during transport while preserving modular assembly capability.
2Weight of moving object
If separate stand rods are used to support foam panels, then the wall can be assembled from modular components, but the stand rods are bulky and difficult to transport
Solution Approach 1:
The support frame and foam panel are combined into a single integrated component, eliminating the need for separate stand rods. This reduces the number of components to transport while maintaining modular assembly capability through the self-supporting design of each panel unit.
Solution Approach 2:
The sound absorbing wall is divided into multiple self-supporting panel units that can be individually transported and then assembled into a complete wall structure. Each panel is a complete functional unit with integrated support, enabling easy transport while maintaining overall system modularity.
3Stability of the object's composition
If peripheral support frames made of reverberant material are used, then structural stability is improved, but sound absorption effectiveness is reduced due to reflection
Solution Approach 1:
The foam panel extends beyond the support frame perimeter, creating a local quality difference where the exposed foam edges provide sound absorption at the boundaries. This compensates for the sound reflection from the support frame, maintaining overall sound absorption effectiveness while preserving the structural stability provided by the support frame.

AI summary
The wall has individual absorber panels (20-23) stacked on one another and comprising stable circular support frames (30), where sound-absorbing plates (40) are flush-mounted at the support frames. Horizontal frame portions (30b) of the support frames of the stacked panels are mechanically connected with each other to form a self-supporting stack. The horizontal frame portions comprise holes for retaining bolts such that the holes of the stacked panels are aligned with each other in a perpendicular direction. The panels are coated with a sound-absorbing non-woven fabric or a color layer.
