Frameless Sound-Absorbing Panels With Guide Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound-absorbing panels are cumbersome due to support frames, costly, and aesthetically unappealing, making them difficult to handle, install, and integrate with interior designs, especially when requiring two visible sides.
Innovation Solution
A system comprising guides with longitudinal grooves allows panels to slide and be fixed without frames, using guides made of materials like wood or metal, and featuring fixing members for wall mounting, enabling flexible arrangement and aesthetic integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If sound-absorbing panels are made with a perimetral frame and sheet covering, then the panel structure is rigid and stable, but the weight increases and aesthetic appearance deteriorates due to visible frames and joints
Solution Approach 1:
The patent removes the perimetral frame from the panel structure entirely. The sheet is no longer wrapped around a frame but is instead stretched and fixed directly between the parallel guides, eliminating the frame component that caused weight increase and aesthetic deterioration while maintaining structural stability through the guide system.
Solution Approach 2:
The support structure is segmented into separate functional components: the guides (which provide structural support and positioning) and the panels (which provide acoustic function). This separation allows the panels to be lighter and more aesthetically pleasing while the guides bear the structural load.
2Strength
If sound-absorbing panels use a perimetral frame with sheet covering, then the panel maintains its shape and rigidity, but the manufacturing cost increases due to the frame being the most costly item
Solution Approach 1:
The patent extracts and eliminates the perimetral frame from the panel construction. The sheet is stretched and secured directly between the guides without requiring a frame, thereby removing the most costly manufacturing component while preserving panel rigidity through the guide system.
3Shape
If the sheet is wrapped around the perimetral frame to mask joints, then the aesthetic appearance improves, but the complexity of installation increases especially when two visible sides are required
Solution Approach 1:
By removing the perimetral frame entirely, the patent eliminates the complex wrapping and joint-masking process. The sheet is simply stretched and fixed between the guides, dramatically simplifying installation while maintaining aesthetic appearance through the tensioned sheet configuration that works equally well on both visible sides.
Solution Approach 2:
Instead of wrapping the sheet around a frame to hide joints, the patent inverts the approach by stretching the sheet taut between guides so that the tensioned surface itself becomes the aesthetic feature, eliminating the need for joint masking entirely.
4Weight of moving object
If sound-absorbing panels are made without frames using only guides and sheets, then the weight is reduced and aesthetics improve, but the panel stability and rigidity must be maintained through alternative means
Solution Approach 1:
The patent introduces parallel guides as intermediary structures that bear the structural load and provide stability. These guides act as mediators between the wall mounting system and the lightweight frameless panels, transferring forces and maintaining panel position without requiring the panels themselves to be rigid or heavy.
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 eliminates the need for support frames, reduces panel weight, enhances aesthetic appeal, and allows for customizable acoustic compositions by adjusting panel positions and types, improving sound absorption and reflection control.
Implementation Method 1
each of said guides comprises at least two guide grooves which extend longitudinally parallel to the longitudinal axis of the guide. One of the grooves acts as a guide for an edge of the first panel and the other of the grooves acts as a guide for an edge of the second panel so that the first and second panels may slide parallel to each other.
Implementation Method 2
Sound-absorbing materials have the property that they absorb at least a part of the acoustic energy and reduce the amount of reflected energy.
Implementation Method 3
For each guide, at least one fixing member may be provided. The fixing member may comprise a wall mount with a pin and a screw configured to engage inside a threaded hole of said pin and a hole in the guide.

AI summary
A system for arranging a plurality of sound-absorbing panels or the like is described. The system includes a first and a second guide and a first and a second panel, and each of said guides further includes a longitudinal axis, and a first longitudinal groove and a second longitudinal groove substantially parallel to said longitudinal axis, such that the first panel is retained in the first groove of the first and second guides and the second panel is retained in the second groove of the first and second guides and further such that at least one of the panels is displaceable in a guided manner inside the respective longitudinal groove.
