Circular Air Outlet Guide Member for Quiet Airflow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners with blade-based airflow controllers face issues such as reduced discharge air volume and increased flow noise due to airflow interference and turbulence, especially when controlling airflow in circular discharge paths.
Innovation Solution
An air conditioner with an airflow controller that uses a guide member and rotating member to control airflow direction without blades, employing a ring-shaped rotating member and guide rails to reciprocate the guide member between internal and external positions of the discharge path, allowing for efficient airflow direction control in circular discharge paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a blade-based discharge airflow control device is used, then the direction of discharge airflow can be controlled, but the discharge volume of air is reduced and flow noise is increased
Solution Approach 1:
The patent removes the blade component from the discharge airflow control device and replaces it with a guide member. This extraction of the problematic blade element eliminates the interference with airflow while maintaining the ability to control airflow direction through the guide member's positioning at different locations.
Solution Approach 2:
The guide member serves as an intermediary element between the airflow control requirement and the airflow path. Instead of using a blade that directly blocks and redirects airflow, the guide member subtly guides the airflow direction by its presence at specific locations, reducing turbulence and maintaining discharge volume.
2Ease of operation
If a blade-based discharge airflow control device is used, then the direction of discharge airflow can be controlled, but flow noise is increased
Solution Approach 1:
By removing the blade from the system, the source of turbulence-induced noise is eliminated. The guide member replaces the blade's directional control function without creating the same level of airflow disturbance that generates flow noise.
Solution Approach 2:
The patent converts the potential harm of airflow interference into a beneficial smooth guidance mechanism. The guide member's design allows airflow to follow a smoother path, transforming what would have been turbulent, noisy flow into laminar, quiet flow while maintaining directional control.
3Ease of operation
If a guide member is moved between internal and external positions of the discharge path, then airflow direction control is improved, but device complexity increases
Solution Approach 1:
The guide member is designed to be movable between different locations (internal and external positions of the discharge path) rather than fixed. This dynamic positioning allows the same component to serve multiple airflow control functions, simplifying the overall device structure while maintaining operational flexibility.
Solution Approach 2:
The single guide member performs multiple functions by being positioned at different locations. When positioned internally, it provides one type of airflow control; when positioned externally, it provides another type. This multi-functionality reduces the need for multiple separate components, thereby reducing device complexity.

AI summary
Provided is an air conditioner including a housing including a discharge path, a first discharge wall forming the discharge path, and a second discharge wall arranged at a side opposite to the first discharge wall and an airflow controller including a guide member configured to move between a first location provided at an inside of the first discharge wall and a second location protruding outside of the first discharge wall. The air conditioner controls a discharge airflow while minimizing loss of discharge air volume through an airflow controller without using a general blade, and controls a discharge airflow of air discharged through a discharge path having a circular shape.
