Soundproof Booth Ventilation Using Integrated Wall-Channel Air Outlets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Open plan office environments require flexible and private spaces for workers, but existing isolated offices are inflexible and lack effective air circulation/ventilation systems, especially for freestanding soundproof booths that cannot be connected to surrounding ventilation systems.
Innovation Solution
A freestanding soundproof booth with an integrated ventilation system featuring a fan, air inlets, and an indirect air outlet path with apertures and channels within the walls and roof, allowing for efficient airflow and sound attenuation without connecting to external ventilation systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If freestanding soundproof booths are used to provide flexible private spaces, then adaptability and ease of relocation are improved, but effective air circulation and temperature control deteriorate due to inability to connect to external ventilation systems
Solution Approach 1:
The ventilation system is merged with the booth structure itself, integrating the fan, air channels, and apertures directly into the wall and roof assemblies. This self-contained integration allows the booth to function as a complete ventilation unit without external connections, resolving the contradiction between relocatability and temperature control.
Solution Approach 2:
The walls and roof serve multiple functions: they provide soundproofing, structural support, and simultaneously house the ventilation channels and apertures. This multi-functionality allows the same structural elements to fulfill both acoustic isolation and air circulation requirements, addressing the temperature control issue while maintaining booth flexibility.
2Productivity
If air outlets are provided on multiple surfaces of the booth, then ventilation effectiveness is improved, but sound transmission between adjacent booths deteriorates
Solution Approach 1:
The air outlet channels are routed through the thickness of the wall and roof structures, utilizing the dimensional space within the wall assembly rather than protruding outward. This dimensional approach allows air to exit through multiple surfaces while keeping the ventilation pathways enclosed within the soundproofing envelope, preventing sound leakage.
Solution Approach 2:
The wall and roof structures themselves act as intermediary elements that contain and guide the air outlet channels. These structural intermediaries provide both the ventilation pathway and the soundproofing barrier, allowing air to pass through while blocking sound transmission to adjacent spaces.
3Object-generated harmful factors
If ventilation channels are routed through wall structures, then sound attenuation is improved, but device complexity increases
Solution Approach 1:
The ventilation channels are merged with the wall and roof structures, using the same manufacturing processes and material layers to create both the structural assembly and the ventilation pathway. This integration eliminates the need for separate ventilation ducts and reduces overall system complexity while maintaining effective sound attenuation.
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 solution provides effective air circulation and soundproofing for freestanding booths, maintaining internal temperature and reducing sound transmission, while being adaptable to various space configurations and user needs without degrading cooling performance.
Implementation Method 1
at least one fan for providing an airflow
Implementation Method 2
the air outlet channel is provided inside one of the walls of the booth... An indirect air path from the first air outlet aperture to the second air outlet aperture... An indirect air path means that the air path has curves or bends between the first air outlet aperture and the second air outlet aperture
