Air blower
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air blowers produce air currents that diffuse when airflows from two opposing edges collide, reducing the forward flow rate and creating an inefficient air distribution pattern.
Innovation Solution
An air blower design featuring a frame member with multiple blowout ports arranged to direct airflows from four different directions, which collide and produce a focused air current towards a central panel, utilizing cross-flow fans and a controller to adjust airflow rates and directions for optimal distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If airflows are blown out from two opposing edges and collide, then air distribution is achieved, but the air current diffuses and forward flow rate decreases
Solution Approach 1:
The frame member is divided into multiple sections with blowout ports at different locations (front, rear, left, right edges), allowing airflows to be segmented into multiple directed streams that converge toward the center panel, preventing diffusion and maintaining forward flow rate
Solution Approach 2:
The blowout ports are asymmetrically positioned and oriented to direct airflows from four different directions (front, rear, left, right) toward the central panel, creating a focused convergence pattern rather than symmetric opposition, which prevents diffusion and enhances forward flow concentration
2Productivity
If airflows collide from multiple directions, then airflow concentration towards panel is improved, but device complexity increases
Solution Approach 1:
The frame member serves multiple functions: it provides structural support, contains the fans, and acts as the airflow distribution system with integrated blowout ports. This multi-functionality reduces the need for additional components, maintaining simplicity while achieving multi-directional airflow concentration
Solution Approach 2:
Multiple airflow generation functions are merged into a single frame member structure with multiple blowout ports, rather than using separate devices for each direction. This consolidation achieves complex multi-directional airflow control without proportionally increasing device complexity
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 design enhances airflow directionality and concentration, preventing diffusion and ensuring most airflows reach the panel, providing a more efficient and realistic air distribution similar to natural wind patterns.
Implementation Method 1
a fan that sends air to the blowout port
Implementation Method 2
the frame member blows out 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

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).
