Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional soundproof windows that are non-openable lack ventilation, and those that are openable often fail to provide adequate noise insulation in high-noise environments, such as near harbors or airports, compromising both user comfort and noise protection.

Innovation Solution

A window arrangement featuring a ventilation duct formed from an acoustic absorber element arrangement that can be attached in front of the window, allowing air flow while reducing sound transmission by incorporating deflections and open-pored materials like mineral wool or rock wool, ensuring seamless integration and effective sound absorption.

1Object-affected harmful factors

If a non-openable soundproof window is used, then sound insulation is improved, but ventilation capability deteriorates

Engineering Contradiction:

Improvesound insulationVSAvoidventilation capability

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The window system is divided into two separate components: a fixed soundproof window and a movable window attachment. The soundproof window remains closed to maintain sound insulation, while the window attachment can be opened independently to provide ventilation. This segmentation allows both functions to operate simultaneously without compromising either sound protection or air exchange capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The ventilation duct acts as an intermediary element that connects the interior space to the exterior environment while passing through the soundproof window structure. It enables air flow without requiring the main window to open, thus maintaining sound insulation while providing ventilation functionality through a separate pathway.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If a ventilation duct is added to a soundproof window, then ventilation capability is improved, but device complexity increases

Engineering Contradiction:

Improveventilation capabilityVSAvoiddevice complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The ventilation duct is integrated into the window attachment structure, merging the ventilation function with the existing movable window component. This combination allows the ventilation duct to be installed and operated as part of the window attachment system, reducing the need for separate complex ventilation infrastructure and simplifying overall system integration.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The ventilation duct is formed from acoustic absorber element arrangement, which provides both ventilation functionality and sound absorption properties. This use of porous acoustic materials allows the duct to serve dual purposes: enabling air flow while maintaining sound insulation, thereby reducing the need for additional separate components and simplifying the overall system design.

Inventive Principle:

Principle #31Porous materials
