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

VSEngineering 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

Engineering Contradiction:
Improveflexibility and relocatability of boothVSAvoidinternal temperature control
Core Design Contradiction:
Adaptability or versatilityVSTemperature

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If air outlets are provided on multiple surfaces of the booth, then ventilation effectiveness is improved, but sound transmission between adjacent booths deteriorates

Engineering Contradiction:
Improveventilation effectivenessVSAvoidsound transmission
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-generated harmful factors

If ventilation channels are routed through wall structures, then sound attenuation is improved, but device complexity increases

Engineering Contradiction:
Improvesound attenuationVSAvoidventilation system complexity
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)
