Blower with Slit Housing for Vertical Airflow Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air circulators with compact designs are limited in their vertical swinging range, preventing them from directing airflow downward below the horizontal direction, which restricts their placement and functionality on shelves or windowsills.
Innovation Solution
A blower design featuring a blower unit supported by slits within a housing, with support pillars inserted through these slits, allowing for vertical pivoting and enabling airflow direction below the horizontal plane while maintaining a compact form factor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the blower unit is supported by two support pillars stood on a base with a wider distance than the width of the blower unit, then the blower can swing vertically, but the width of the base becomes wider than the blower unit, making the device hard to be down-sized
Solution Approach 1:
The support pillars are nested within the blower unit housing rather than being external. The pillars extend through slits in the housing, allowing the blower unit to pivot vertically while the support structure remains contained within the overall device footprint, eliminating the need for a wider base
Solution Approach 2:
The support pillars are positioned at the rear end of the blower unit and extend forward, with slits formed in the housing to accommodate their movement. This repositioning in the longitudinal dimension allows vertical swinging without increasing the lateral base width
2Area of stationary object
If slits are formed on the casing and support pillars are inserted through the slits to support the blower unit, then the device can be made compact, but the vertical swinging range is limited to horizontal to obliquely upward direction, preventing downward airflow
Solution Approach 1:
The support pillars are positioned asymmetrically at the rear end of the blower unit rather than at the center or front. This asymmetric positioning, combined with slits extending along the pillar length, creates an uneven moment distribution that enables the blower unit to swing not only upward but also downward below the horizontal direction, expanding the swinging range while maintaining compact dimensions

AI summary
A blower (1) according to a present embodiment includes a blower unit (2) that has a housing (20) on which a slit (210) is formed to extend vertically, and a support unit (3) that has a support pillar (33) inserted through the slit (210) and pivotally coupled with the blower unit (2) to be swingable vertically. And, by forming a distance (D1) between a lower end (210a) of the slit (210) and the support pillar (33) in a horizontally directed state in which an airflow direction (F) of the blower unit (2) is in line with a horizontal direction, it is configured to make the blower unit (2) swingable such that the airflow direction (F) of the blower unit (2) is directed toward a lower side below the horizontal direction.
