Segmented Air Outlet Vanes for Wider Air Conditioner Throw
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wall-mounted air conditioners face limitations in expanding the wind direction range of discharged air due to fixed vane arrangements, leading to restricted airflow and potential distortion or heavy load on moving parts.
Innovation Solution
The air conditioner features a discharge passage formed at a lower front side with a first vane and second vane arrangement, utilizing links and a motor to rotate the vanes, allowing for increased airflow distance and stable movement, while maintaining control over the wind direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the discharge passage is formed at a lower side in a wall-mounted air conditioner, then the wind direction range can be expanded, but the vanes require larger rotation range which increases device complexity and may cause distortion or heavy load
Solution Approach 1:
The discharge port is divided into multiple segments (first discharge port, second discharge port, third discharge port) arranged at different positions and orientations. Each segment can be independently covered by corresponding vanes, allowing the system to achieve comprehensive wind direction control without requiring excessive rotation range from individual vanes, thus reducing mechanical complexity and distortion risk.
2Productivity
If the discharge port has a long horizontal length to discharge air through a single port, then the air discharge function is simplified, but the vanes covering the discharge port become long which causes distortion and imposes heavy load on links
Solution Approach 1:
The long horizontal discharge port is segmented into multiple shorter discharge ports (first, second, and third discharge ports) positioned at different locations. Each segment is covered by correspondingly sized vanes, eliminating the need for long vanes that would be prone to distortion and heavy loading, while maintaining effective air discharge capability through the distributed port arrangement.
3Adaptability or versatility
If two vanes are used to cover the discharge port, then the wind direction control is improved, but the links for moving the vanes experience heavy load and potential distortion
Solution Approach 1:
The wind direction control function is segmented across multiple discharge ports and multiple vanes (first vane, second vane, third vane). Each vane manages a specific discharge port and wind direction sector, distributing the mechanical load on links rather than concentrating it on fewer vanes, thereby reducing stress and distortion while maintaining comprehensive wind direction control.
