Air Diffuser Baffle Layout for Multi-Room Airflow and Soundproofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air distribution systems in buildings struggle to efficiently direct air from a single duct to multiple rooms, especially in environments with movable walls, requiring additional ducting or intrusive installations, which is costly and inefficient.
Innovation Solution
An air distribution system featuring an air diffuser with a baffle that splits air flow into multiple components, allowing adjustable distribution to multiple rooms through separate outlets on either side of a partition, enabling precise control of airflow ratios and soundproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional air distribution system uses a single duct and diffuser per room, then each room receives dedicated air supply, but additional ducting and intrusive installation are required to serve multiple rooms, increasing device complexity and installation cost
Solution Approach 1:
The patent combines multiple air outlets and plenums into a single integrated diffuser unit that can serve multiple rooms from one duct connection. The diffuser incorporates first and second plenums with respective outlets on opposite sides of a partition, allowing one duct to supply air to multiple rooms without requiring separate ducting for each room.
Solution Approach 2:
The diffuser is designed as a multi-functional device that can simultaneously serve multiple rooms and adapt to different wall configurations. The adjustable baffle system allows the same diffuser unit to distribute air in various ratios to different rooms, making it universally applicable to different spatial arrangements without requiring custom installations.
2Adaptability or versatility
If movable walls are used to accommodate different room configurations, then space flexibility is improved, but conventional air distribution systems cannot efficiently deliver air to different rooms
Solution Approach 1:
The patent incorporates an adjustable baffle within the diffuser that can be dynamically repositioned to change airflow distribution ratios. This dynamic adjustment capability allows the air distribution system to adapt to different room configurations created by movable walls, maintaining efficient air delivery regardless of how the partition is positioned.
Solution Approach 2:
The system changes the airflow distribution parameter by adjusting the baffle position, which modifies the ratio of air delivered to each room. This parameter adjustment enables the same physical diffuser to efficiently serve different room configurations without requiring structural modifications.
3Reliability
If additional ducting is installed to serve multiple rooms from separate outlets, then each room receives dedicated air supply, but installation cost and structural intrusion increase
Solution Approach 1:
The patent merges multiple air supply functions into a single diffuser unit connected to one duct, eliminating the need for additional ducting while maintaining reliable air supply to multiple rooms. The integrated design with multiple plenums and outlets provides dedicated airflow paths to each room without requiring separate duct installations.
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
This system allows for efficient and accurate air distribution to multiple rooms from a single duct, maintaining control and soundproofing regardless of wall configurations, and can be supported independently without additional structural support.
Implementation Method 1
a baffle positioned in the receiving body and configured to distribute air received from the air distribution system selectively to the first plenum and second plenum in a predetermined flow ratio
Implementation Method 2
Air received from the air distribution system is delivered to the first and second room according to the predefined flow ratio through the receiving body, through the first and second plenums, and through the first and second outlets

AI summary
An air diffuser having a single air inlet has air outlets straddling a wall of a structure to distribute air to two or more rooms of the structure. The air diffuser includes an adjustable baffle that selectively directs air toward the first and second rooms. The air diffuser includes an acoustic dampener that prevents sound from moving through the air diffuser from one room to the next.
