Ceiling Indoor AC Vane Sequencing for Round Swing Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling type indoor units of air conditioners have limitations in controlling discharge vane modules, making it difficult to provide natural wind patterns and efficient air distribution within indoor spaces.
Innovation Solution
A method for sequentially controlling four vane modules in successive order and rotating them clockwise or counterclockwise to generate round swing wind patterns, minimizing dead zones and providing both direct and indirect wind distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the discharge vane is simply controlled (rotated or fixed) in conventional ceiling type indoor units, then the control mechanism is simple, but it is difficult to satisfy user desires and provide natural wind patterns
Solution Approach 1:
The discharge vane is divided into four separate vane modules (first, second, third, and fourth vane modules) arranged at different positions. Each module can be independently controlled to rotate sequentially in clockwise or counterclockwise direction, enabling complex wind patterns while maintaining simple individual control mechanisms.
Solution Approach 2:
The vane modules transition from static or simple rotational control to dynamic sequential rotation. The control method enables the vanes to rotate in a specific sequence (first→second→third→fourth module and vice versa), creating dynamic wind patterns including natural wind, indirect wind, and direct wind modes that adapt to different operational requirements.
2Adaptability or versatility
If four vane modules are sequentially controlled in successive order, then natural wind patterns are provided, but the control complexity increases
Solution Approach 1:
The vane modules operate through periodic sequential rotation following a fixed cycle: first module→second module→third module→fourth module→first module, and the reverse direction. This periodic action creates consistent natural wind patterns while simplifying control logic through predictable, repeating sequences rather than complex arbitrary control.
Solution Approach 2:
The control of four separate vane modules is merged into a unified sequential control system. Instead of controlling each module independently, the system combines them into a coordinated sequence where each module follows the previous one, creating complex wind patterns through simple combined action rather than complex individual controls.
3Adaptability or versatility
If vane modules are continuously controlled in clockwise or counterclockwise direction, then round swing wind patterns are generated, but control precision requirements increase
Solution Approach 1:
The continuous rotational movement is segmented into discrete modular steps corresponding to the four vane modules. Each module rotates to a specific position in sequence rather than requiring continuous precise control of a single vane, reducing measurement precision requirements while maintaining effective round swing wind pattern generation.

AI summary
A first vane module, a second vane module, a third vane module, and a fourth vane module are sequentially controlled in successive order, thereby generating round swing wind swirling around an indoor unit. Consequently, it is possible to provide direct wind in the discharge direction of each vane module and to provide indirect wind to an indoor space deviating from the discharge direction of each vane module.
