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

VSEngineering 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

Engineering Contradiction:
Improvestructural strengthVSAvoidassembly speed
Core Design Contradiction:
StrengthVSProductivity

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

Inventive Principle:
Principle #1Segmentation

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

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
Improvestructural stabilityVSAvoidmanufacturing cost
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #25Self-service

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

Engineering Contradiction:
Improveon-site assembly timeVSAvoidtransportation volume
Core Design Contradiction:
Loss of timeVSVolume of moving object

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

Inventive Principle:
Principle #1Segmentation

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

Inventive Principle:
Principle #7Nested doll (Nesting)

4Volume of moving object

If acoustic panels are designed as modular units, then the transportation efficiency is improved, but the assembly complexity increases

Engineering Contradiction:
Improvetransportation volumeVSAvoidassembly complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

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

Inventive Principle:
Principle #1Segmentation

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

Inventive Principle:
Principle #7Nested doll (Nesting)
