Sandwich-Wall Ventilation Channels for Soundproof Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Movable soundproof spaces face challenges in ventilation due to the need for non-bulky structures that maintain soundproofing and minimize noise, as traditional ventilation systems can compromise soundproofing and produce unwanted noise.
Innovation Solution
A sandwich-type wall, roof, or floor structure with integrated ventilation channels and fans that form indirect air paths with curves and bends, ensuring adequate airflow without compromising soundproofing or increasing bulk, and positioning apertures to minimize noise impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional ventilation systems are installed in movable soundproof spaces, then air circulation is improved, but soundproofing is compromised and noise increases
Solution Approach 1:
The air channel is divided into multiple separate channels (first air channel, second air channel, third air channel, fourth air channel) formed in different layers of the sandwich-type wall structure. Each channel is isolated from the others, preventing sound transmission through air gaps while maintaining ventilation functionality. The segmentation of air paths ensures that sound cannot easily transmit from one side to another through the ventilation system.
Solution Approach 2:
The air channels are nested within the layers of the sandwich-type wall structure, with channels formed in panel layers that are part of the composite wall assembly. The ventilation system is integrated into the existing wall structure rather than added as a separate external component, allowing the air channels to be embedded within the soundproofing layers themselves.
Solution Approach 3:
The air channels incorporate curves and bends in their path through the wall structure, rather than straight linear paths. The channels include curved sections that redirect air flow while maintaining sound isolation. The curved geometry helps prevent direct sound transmission paths while still allowing adequate air circulation through the ventilation system.
2Object-affected harmful factors
If thick walls are used to maintain soundproofing, then sound isolation is improved, but the structure becomes bulky and difficult to arrange ventilation components
Solution Approach 1:
The air channels utilize the thickness dimension of the sandwich-type wall structure by forming channels within the panel layers themselves. Rather than requiring additional external space for ventilation ducts, the channels are created by removing or modifying material within the existing wall thickness, effectively using the third dimension (depth) of the wall to accommodate ventilation pathways.
Solution Approach 2:
The sandwich-type wall structure uses different materials with specific properties in different layers - sound-absorbing materials in some layers and sound-blocking materials in others. The air channels are strategically positioned in layers where they will not compromise overall sound isolation. This local differentiation of material properties allows the wall to maintain soundproofing while accommodating ventilation channels.
3Productivity
If ventilation apertures are positioned for optimal air flow, then ventilation efficiency is improved, but noise transmission increases
Solution Approach 1:
The air channels include curved sections and bends in their path from the inlet aperture to the interior space. These curves and bends redirect air flow while preventing direct sound transmission paths. The curved geometry diffuses sound waves and prevents noise from traveling straight through the ventilation system, thereby reducing noise transmission while maintaining ventilation efficiency.
