Air Blowing Device Side Ventilation for Uniform Multi-Unit Flow
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 directs air flow uniformly across the downstream area, preventing air from flowing between devices and ensuring a uniform air flow or clean air supply.
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 configuring different ventilation hole distributions in different regions of the air-permeable front surface. The side surface portions have ventilation holes specifically arranged to blow air outward toward adjacent devices, while the central region maintains uniform flow characteristics. This localized differentiation ensures that each region of the aligned device configuration receives appropriate air supply, maintaining uniformity across the entire covered area.
Solution Approach 2:
The patent introduces a width-direction component to the air flow by adding side surface portions with ventilation holes that blow air outward in the width direction. This dimensional addition allows air to be supplied not only in the front-rear direction but also laterally toward adjacent devices, ensuring uniform air distribution across the entire multi-device configuration area.
2Manufacturing precision
If air is blown outward from side surface portions toward adjacent devices, then air supply between aligned devices improves, but air flow uniformity in the forward direction may be affected
Solution Approach 1:
The patent segments the air flow into two distinct components: forward flow through the air-permeable front surface and lateral flow through the side surface portions. This segmentation allows independent optimization of each flow direction - the front surface maintains forward uniformity while the side portions provide lateral coverage, and the two components work together to achieve overall uniformity without compromising each other.
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 configuration ensures a uniform air flow or clean air supply across the entire width or height 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 that are disposed at respective side portions of the air-permeable front surface in the width direction... a plurality of second ventilation holes are distributed at at least one of the side surface portions opposite to each other in the width direction, wherein the second ventilation holes are 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).
