Solution Overview

Problem

Existing soundproof panels made of transparent materials for noise barriers suffer from light reflection issues, causing glare for motorists and residents, and the attached films or coatings are prone to detachment over time.

Innovation Solution

A soundproof panel with an anti-glare function is developed, featuring a base layer made of polycarbonate or polymethyl methacrylate and integrally formed anti-glare protrusions containing anti-glare particles with a specific particle diameter range, which provide diffuse reflection to prevent glare.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If transparent materials are used for soundproof panels, then aesthetic appeal and transparency are improved, but light reflection causing glare worsens

Engineering Contradiction:
ImprovetransparencyVSAvoidglare from light reflection
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by creating anti-glare protrusions only on the light-incident surface of the soundproof panel, while maintaining the transparency of the base material. These protrusions are distributed locally to scatter light without compromising the overall aesthetic appeal and transparency of the panel.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent employs spheroidality by forming protrusions with curved, dome-like surfaces on the panel surface. These curved surfaces effectively scatter incident light in multiple directions, reducing glare while maintaining a visually appealing appearance that complements the transparent material.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Object-affected harmful factors

If films are attached to glass surfaces to reduce light reflection, then anti-glare effect is improved, but durability worsens due to detachment over time

Engineering Contradiction:
Improvelight reflectionVSAvoiddurability of film attachment
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent merges the anti-glare function directly into the soundproof panel structure by forming protrusions on the panel itself rather than attaching separate films. This integration ensures the anti-glare effect is permanently embedded in the material, eliminating detachment issues while maintaining effective light scattering.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent uses composite materials by combining the transparent base material (polycarbonate or polymethyl methacrylate) with protrusion structures that have different surface properties. This composite approach allows the panel to maintain transparency while the protrusions provide durable anti-glare functionality.

Inventive Principle:
Principle #40Composite materials

3Object-affected harmful factors

If coatings are applied on glass surfaces to reduce light reflection, then anti-glare effect is improved, but durability worsens due to coating detachment

Engineering Contradiction:
Improvelight reflectionVSAvoidservice life of coating
Core Design Contradiction:
Object-affected harmful factorsVSDuration of action of stationary object

Solution Approach 1:

The patent merges the anti-glare function directly into the soundproof panel structure by forming protrusions on the panel itself rather than attaching separate films. This integration ensures the anti-glare effect is permanently embedded in the material, eliminating detachment issues while maintaining effective light scattering.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent avoids using separate detachable coatings or films that have limited service lives. Instead, the anti-glare protrusions are formed as an integral part of the soundproof panel, ensuring long-term durability without requiring replacement or maintenance.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

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 soundproof panel effectively prevents glare by diffuse reflection of incident light, maintains durability and aesthetic appeal, and does not require frequent replacement due to the integral formation of the anti-glare protrusions.
