Multi-Directional Air Blower Frame Design to Reduce Airflow Diffusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air blowers with pseudo windows face challenges in directing airflows effectively, as the collided airflows tend to diffuse towards the edges from which no airflow is produced, making it difficult to send them in a predetermined direction.
Innovation Solution
An air blower design with a frame member having multiple blowout ports arranged to produce airflows from different directions, which collide and guide the air current forward, reducing diffusion and allowing for adjustable airflow direction through a controller that regulates fan speeds and flow rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If airflows are blown out from two opposing edges and collide with each other, then the structure is simple, but the collided airflows diffuse toward the edges from which no airflow is produced, making it difficult to send them in a predetermined direction
Solution Approach 1:
The frame member is divided into multiple blowout ports (first, second, third, and fourth blowout ports) positioned at different locations and orientations. Each blowout port independently directs airflow in a specific direction, allowing segmented control of airflow patterns to prevent unwanted diffusion while maintaining overall system functionality.
2Ease of operation
If multiple blowout ports are arranged to produce airflows from different directions, then airflow direction control is improved, but the device complexity increases
Solution Approach 1:
Multiple blowout ports are integrated into a single frame member structure that surrounds the panel. The frame member combines several airflow generation functions into one unified component, reducing overall device complexity while maintaining the capability to produce controlled multi-directional airflow patterns.
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 air blower effectively directs airflows from multiple directions, reducing diffusion and allowing for precise control over the airflow direction, enhancing the perceived airflow and its application in various environments.
Implementation Method 1
a fan that sends air to the blowout port
Implementation Method 2
the frame member produces airflows that are blown out from the first blowout port, the second blowout port, the third blowout port, and the fourth blowout port and collide with each other, thereby producing an air current going forward to the panel

AI summary
An air blower includes: a panel (3); a frame member (5) arranged to surround the panel (3) and having a blowout port (13a, 13b, 13c, 13d, 13e, 13f, 13g) of air formed therein; and a fan (11a, 11b, 11c, 11d, 11e, 11f, 30) that sends air to the blowout port (13a, 13b, 13c, 13d, 13e, 13f, 13g). The frame member (5) produces airflows that are blown out from at least three directions and collide with each other, thereby producing an air current going forward to the panel (3).
