Solution Overview

Problem

Existing soundproof panels are heavy, require strong foundations, and are not visually appealing due to material degradation from weather exposure, leading to increased installation costs and potential vibration issues that compromise soundproofing.

Innovation Solution

A lightweight soundproof panel design featuring a row of fiber-covered tubes clamped in U-profiles, with an elongated fixing element and mineral wool for enhanced stiffness and sound absorption, using materials like galvanized steel and coconut fiber to prevent vibration and maintain aesthetic appeal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If heavy materials like concrete are used for soundproof panels, then soundproofing effectiveness is improved, but foundation requirements and installation costs increase

Engineering Contradiction:
Improvesoundproofing effectivenessVSAvoidpanel weight
Core Design Contradiction:
ReliabilityVSWeight of stationary object

Solution Approach 1:

The patent uses a composite structure combining a lightweight core (polystyrene foam or similar insulating material) with outer layers of fiber cement boards or metal sheets. This composite construction achieves the required soundproofing and structural integrity without the weight of solid concrete panels, eliminating the need for heavy foundations and specialized installation equipment.

Inventive Principle:
Principle #40Composite materials

2Shape

If wood is used for soundproof panels to improve visual appeal, then aesthetic properties are improved, but durability worsens due to weather exposure requiring impregnation with unfriendly agents

Engineering Contradiction:
Improvevisual appealVSAvoiddurability
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

The patent applies different materials to different surfaces: the front and back faces use fiber cement boards or metal sheets that provide weather resistance and visual appeal, while the core uses lightweight insulating material. This local differentiation allows the panel to withstand weather exposure without requiring harmful impregnation agents, as the weather-exposed surfaces are inherently resistant.

Inventive Principle:
Principle #3Local quality

3Ease of manufacture

If tubes are loosely attached to the plate, then ease of assembly is improved, but vibration and resonance occur compromising soundproofing

Engineering Contradiction:
Improveassembly easeVSAvoidsoundproofing performance
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent incorporates U-profiles during the panel manufacturing process itself, embedding them into the plate structure before the tubes are attached. This preliminary integration ensures that the tubes are properly positioned and secured, preventing vibration and resonance while maintaining the ease of assembly through the standardized U-profile connection system.

Inventive Principle:
Principle #10Preliminary action
