Air blowing device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air blowing devices fail to provide a uniform flow of air or clean air when aligned horizontally or vertically, resulting in inadequate air supply between and downstream of the devices, which is inappropriate for working spaces.
Innovation Solution
The air blowing device incorporates a rectifier mechanism with an air-permeable front surface and side surface portions featuring ventilation holes, which ensures a uniform air flow by directing air outward in the width and vertical directions, preventing air from flowing between devices and maintaining a uniform air flow across the working space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple air blowing devices are horizontally aligned to expand working space coverage, then the covered area increases, but air supply uniformity deteriorates in the regions between and downstream of the devices
Solution Approach 1:
The patent applies local quality by differentiating the ventilation hole distribution across different regions of the device. The front surface has a first distribution pattern while the side surfaces have a second distribution pattern, with each pattern optimized for its specific location to ensure uniform air supply across the entire working space when multiple devices are aligned horizontally.
Solution Approach 2:
The patent transitions from conventional single-direction (front-only) air blowing to multi-dimensional air distribution by adding side surface ventilation holes. This enables air to be supplied not only in the front-rear direction but also in the width direction, ensuring uniform coverage when devices are horizontally aligned and eliminating dead zones between adjacent devices.
2Stability of the object's composition
If air is blown outward in the width direction from side surface portions, then air supply between horizontally aligned devices is improved, but device complexity increases due to additional ventilation structures
Solution Approach 1:
The patent applies universality by designing the side surface portions to serve dual functions: they act as structural components of the device housing while simultaneously functioning as air distribution surfaces with integrated ventilation holes. This multi-functionality reduces the need for separate air distribution components, thereby limiting the increase in device complexity.
Solution Approach 2:
The patent segments the ventilation system into distinct functional zones: front surface ventilation holes for primary air supply and side surface ventilation holes for lateral air supply. This segmentation allows each zone to be optimized independently while working together to achieve uniform air distribution, managing complexity through functional decomposition.
3Stability of the object's composition
If a rectifier mechanism is added to ensure uniform air flow, then air flow uniformity improves, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent employs porous materials or plates with uniformly distributed ventilation holes as the rectification mechanism. These porous structures naturally distribute air flow uniformly without requiring complex mechanical rectifiers, maintaining ease of manufacture while achieving the desired air flow uniformity through the inherent properties of the porous material.

Function Achieved in This Case
This configuration ensures a uniform air flow across the entire width or vertical area of aligned devices, effectively creating a working space filled with clean air, preventing contamination and maintaining cleanliness.
Implementation Method 1
a rectifier mechanism disposed at a flow path through which air flows from an upstream side toward a downstream side of the flow path, whereby the air past the rectifier mechanism is rendered a uniform air flow to be supplied to a downstream side of the rectifier mechanism
Implementation Method 2
an air-permeable front surface formed at the downstream side of the rectifier mechanism and including a plurality of first ventilation holes distributed in the width direction and the vertical direction
Implementation Method 3
side surface portions extending toward the upstream side from lateral edges of the air-permeable front surface... configured to blow out part of the air past the rectifier mechanism outward in the width direction

AI summary
An air blowing device adapted to be used in such a manner that at least two of the devices are horizontally and/or vertically aligned with each other, thereby to obtain a uniform flow of air in the downstream direction from device to device. An air-permeable front surface (11f) is formed to the blowing device (1) at the downstream side of a rectifier mechanism, and side surface sections (11a) which extend in the upstream direction of the device (1) are formed at both edges of the air-permeable front surface (11f). First ventilation holes (70a) are distributed at the air-permeable front surface (11f), and second ventilation holes (70b) are distributed at the side surface sections (11a).
