Multi-Tower Blower Layout for Uniform Vertical Air Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blowers with multiple discharge ports arranged vertically do not evenly distribute air pressure, leading to intensive clean air supply in local areas rather than uniform distribution across a space.
Innovation Solution
The blower design features a cone-shaped structure with a suction module and a blowing module, where the blowing module includes two towers with discharge ports that are symmetrically arranged to create a blowing space, facilitating uniform air distribution by guiding air flow through a series of flow guides and airflow converters to enhance airflow directionality and distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If multiple discharge ports are arranged vertically to supply clean air to high locations, then the blower can deliver clean air upward, but the air distribution becomes intensive in local areas rather than uniform
Solution Approach 1:
The blowing module is divided into multiple towers (first tower, second tower, third tower) with discharge ports distributed across different heights and positions. This segmentation allows air to be discharged from multiple locations simultaneously, transforming the concentrated local supply into a distributed uniform pattern across the vertical space.
Solution Approach 2:
Each tower and discharge port is positioned to serve specific spatial zones. The first discharge port is at a higher location, the second discharge port is at a lower location, and the third discharge port is at a specific height, creating locally optimized air distribution that collectively achieves overall uniformity throughout the space.
2Area of stationary object
If discharge ports are arranged to cover vertical space, then clean air can reach high locations, but air flow distribution remains uneven with intensive supply to local areas
Solution Approach 1:
The discharge ports are arranged not only vertically but also horizontally across multiple towers positioned at different locations. This multi-dimensional arrangement (vertical height + horizontal position) expands the coverage area while ensuring uniform air distribution by preventing concentration in any single local area.
3Length of moving object
If the blower structure is extended vertically to supply air to high locations, then upward air supply is achieved, but the structure becomes more complex
Solution Approach 1:
Multiple towers with discharge ports are merged into a single integrated blowing module. The first tower, second tower, and third tower are combined within one module, sharing common structural elements and control systems, which reduces overall device complexity while maintaining the vertical extension needed for high location air supply.

Function Achieved in This Case
This design ensures even air distribution in the vertical direction, reducing airflow deviations and variations in clean air supply, thereby improving the blower's ability to circulate clean air uniformly across a space.
Implementation Method 1
a flow guide provided in the space and extending in a direction crossing the longitudinal direction of the discharge port, and an airflow converter provided at the discharge port
Implementation Method 2
air flowing upward may be guided toward the discharge port by the flow guide
