Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional acoustic screens require laborious and costly assembly using screws or rivets, and their transportation is inefficient due to bulkiness, increasing manufacturing and delivery costs.
Innovation Solution
A modular acoustic panel design featuring parallel side plates with longitudinal guides and 'U'-shaped closing profiles that allow sliding assembly without fastening elements, enabling efficient stacking and transportation by allowing the panels to nest within each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional acoustic screens use screws or rivets for assembly, then the structural strength and stability are improved, but the assembly time and manufacturing cost increase
Solution Approach 1:
The acoustic screen is divided into modular panels that can be assembled independently. Each panel contains integrated connection elements (protrusions and recesses) that allow quick coupling without additional fasteners, enabling rapid assembly while maintaining structural integrity through the distributed modular design
Solution Approach 2:
The connection elements (protrusions and recesses) are integrated directly into the panel structure during manufacturing, merging the fastening function with the panel body. This eliminates the need for separate screws or rivets, reducing assembly time while maintaining adequate structural strength through the built-in mechanical coupling
2Stability of the object's composition
If conventional acoustic screens use screws or rivets for assembly, then the structural stability is improved, but the manufacturing cost increases
Solution Approach 1:
The connection elements are manufactured as integral parts of the panels, combining the panel fabrication and fastener production into a single manufacturing process. This eliminates the need to purchase and install separate fastening elements, reducing overall manufacturing cost while maintaining structural stability through the designed mechanical interlock
Solution Approach 2:
The panels are designed with self-aligning and self-latching connection features where protrusions fit into recesses without requiring external tools or additional components. The structure serves its own fastening needs, eliminating the cost of separate fasteners and the labor for their installation while maintaining adequate structural stability
3Loss of time
If acoustic panels are delivered assembled from the workshop, then the assembly time on site is reduced, but the transportation space and cost increase
Solution Approach 1:
The acoustic screen is divided into smaller modular panels that can be transported in a compact, space-efficient manner. These modules can be stacked or nested during transportation, significantly reducing the volume required compared to delivering fully assembled structures, while still enabling rapid on-site assembly through the integrated connection elements
Solution Approach 2:
The modular panels are designed to nest within each other during transportation, with smaller panels fitting into the spaces of larger panels or stacking in configured arrangements. This nesting capability dramatically reduces the transportation volume required while maintaining the ability to quickly assemble the complete structure on-site through the integrated connection system
4Volume of moving object
If acoustic panels are designed as modular units, then the transportation efficiency is improved, but the assembly complexity increases
Solution Approach 1:
While segmentation into modules increases transportation efficiency, the connection mechanism is designed to be simple and intuitive, with protrusions and recesses that naturally guide alignment and require minimal assembly steps. The modular design standardizes the connection interfaces, actually reducing overall assembly complexity compared to custom-fit assembled structures
Solution Approach 2:
The nesting design for compact transportation incorporates alignment features and connection elements that guide the panels into their assembled positions automatically. The same geometric features that enable compact nesting also facilitate simple assembly, reducing the need for complex alignment procedures or additional fastening operations

AI summary
Modular panel for acoustic screens, intended to isolate and protect an inhabited area from ambient noise that occurs in an adjoining area, for example, roads, railways, or airports; the panel comprising two plates arranged in parallel and a filling of noise absorbent material arranged between the two plates; at least one plate having a plurality of perforations (10) for access of the noise to the interior of the panel (1); each of the plates (1a 1b) comprising a rectangular surface (11) which affects the entire length of the panel (1) and extensions (12a, 12b) on its longitudinal edges that form longitudinal guides for the sliding assembly of closing profiles (2a, 2b) of the top and bottom ends of the panel (1).
