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 features an air-permeable front surface with strategically positioned ventilation holes that extend beyond the rectifier mechanism, allowing air to expand and collide with adjacent devices, ensuring a uniform flow of air across the entire working space by preventing rear-side air from flowing forward.
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 spaces between and downstream of the devices
Solution Approach 1:
The patent applies local quality by creating different airflow characteristics at different locations of the device. The front surface is designed with air-permeable portions having ventilation holes that allow air to escape laterally, while the rear surface has a different structure. This local differentiation enables the device to maintain uniform air supply even when multiple devices are aligned horizontally, resolving the contradiction between expanded coverage area and air supply uniformity.
Solution Approach 2:
The patent introduces a new dimension to the airflow pattern by allowing air to escape not only in the forward direction but also laterally through the front surface ventilation holes. This multi-directional airflow approach (adding lateral dimension to the primarily forward flow) enables better air distribution in the spaces between horizontally aligned devices, maintaining uniformity while expanding coverage area.
2Manufacturing precision
If air-permeable front surface extends beyond rectifier mechanism to enable lateral air expansion, then air flow distribution improves, but device structure complexity increases
Solution Approach 1:
The patent applies the porous materials principle by making the front surface air-permeable with distributed ventilation holes. Instead of a solid front surface, the design uses a porous or perforated structure that allows air to pass through laterally. This achieves improved air flow distribution uniformity while keeping the structure relatively simple, as the air-permeable front surface can be integrated with the existing device housing rather than adding separate complex components.

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).
