Blower Damper Segmentation for Airflow Direction Control and Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blowers lack the ability to control airflow direction effectively, and there is a need for a structure that can adjust the blowing direction and improve the rigidity of dampers while allowing easy coupling and detachment.
Innovation Solution
A blower design featuring a fan, lower and upper bodies with movable dampers and bars that allow for adjustable airflow direction, enhanced damper rigidity, and easy coupling, utilizing a damper driving mechanism and a structure that includes a first and second upper body with inner and outer panels to form airflow paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a damper is made movable to control airflow direction, then the blowing direction can be adjusted, but the structural rigidity deteriorates
Solution Approach 1:
The damper is divided into multiple segments or sections that can move independently relative to each other. This segmentation allows the damper to achieve directional control through relative movement of segments while each segment maintains its own structural rigidity. The segmented structure reduces the overall flexibility requirement compared to a single-piece movable damper.
Solution Approach 2:
The damper incorporates composite material construction combining rigid and flexible properties. This allows the damper to maintain sufficient rigidity for structural stability while having specific portions or mechanisms that enable controlled movement for airflow direction adjustment.
2Strength
If a bar is coupled to the damper to improve rigidity, then the structural stability improves, but the coupling and detachment process becomes more complex
Solution Approach 1:
The coupling mechanism between the bar and damper is designed to be dynamically adjustable rather than permanently fixed. This allows the bar to be easily coupled to or detached from the damper when needed, while still providing rigidity support during operation. The dynamic coupling mechanism simplifies manufacturing and assembly compared to permanent attachment methods.
3Stability of the object's composition
If the damper structure is reinforced to improve rigidity, then the structural stability improves, but the device complexity increases
Solution Approach 1:
Instead of uniformly reinforcing the entire damper structure, reinforcement is applied locally only where structural stability is most needed. This localized reinforcement approach maintains overall structural stability while minimizing the addition of complex structural elements throughout the entire damper assembly.

AI summary
Disclosed is a blower. The blower includes: a fan that generates a flow of air; a lower body that includes an internal space in which the fan is installed, and a suction hole providing air to the fan; a first upper body that is positioned above the lower body, communicates with the internal space of the lower body, and has a surface at which a first discharge hole is formed; a first damper that is movably coupled to the first upper body to selectively penetrate the surface of the first upper body, the first damper having a first end facing an outside of the first upper body, and a second end opposite to the first end; and a first bar extending along and coupled to the second end of the first damper.
