Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blowers, such as axial fans, struggle to provide intense or concentrated air flow in narrow regions and often lack the space for air flow paths to accommodate heaters, and they do not effectively display information without interfering with air flow.
Innovation Solution
The design incorporates a blower with a unique configuration of towers and airflow converters that utilize the Coanda effect to enhance air flow concentration and include a display module positioned to minimize interference with air discharge, allowing for improved air flow straightness and concentration by joining air from multiple discharge ports in a blowing space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If an axial fan is used to provide wide air flow coverage, then the air flow covers a wide range, but the air flow is not concentrated or intense in narrow regions
Solution Approach 1:
The blower is divided into multiple discharge ports (first discharge port and second discharge port) with different functions. The first discharge port provides wide coverage air flow while the second discharge port provides concentrated air flow in narrow regions. This segmentation allows the system to simultaneously achieve both wide coverage and concentrated air flow delivery.
2Adaptability or versatility
If the air flow path is configured with sufficient space, then heaters can be installed to heat air, but the overall device size increases
Solution Approach 1:
The heater is installed within the existing air flow path structure between the fan and discharge ports, utilizing the available space efficiently. The heater is nested within the blower assembly rather than requiring external space, allowing thermal processing functionality to be integrated without significantly increasing the overall device volume.
3Loss of information
If a display is added to show fan information, then information display is enabled, but the display interferes with the flow of discharged air
Solution Approach 1:
The display is positioned in a specific location on the blower housing where it does not obstruct the air flow path. By carefully selecting the display location in a region that does not interfere with the discharged air flow, the system achieves both information display functionality and maintains air discharge efficiency.

AI summary
A blower may include a first case and a second case provided above the first case and having a first tower and a second tower that have a passage therebetween. A display assembly is received in the second case at a position that does not interfere with air flowing in the passage. An inner surface of the second tower and an outer surface of a diffuser define a space in which the display assembly is received.
