Solution Overview
Problem
Existing air regulating devices face challenges in defining the initial position of blades in air sweeping assemblies, leading to complexity in controlling the rotation angle and air direction regulation.
Innovation Solution
The air sweeping assembly incorporates a first position limiting member on a stationary fixing portion and a second position limiting member on the rotation shaft, allowing for a defined initial position of the rotation shaft and blades, simplifying the control of the rotation angle and air direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a position limiting structure is designed on the moving air guiding plate, then the initial position of the blades can be limited, but the structure becomes complex and the control program to find the initial position becomes complicated
Solution Approach 1:
Instead of placing the position limiting structure on the moving air guiding plate, the patent inverts the approach by placing the position limiting structure on the stationary housing. This allows the initial position to be defined through the relative position between the movable blade and the fixed limiting structure, simplifying both the structure and control program.
Solution Approach 2:
The patent introduces a mediator element (the position limiting structure on housing) that indirectly defines the initial position of the blade. The limiting structure acts as an intermediary reference point, allowing the blade's initial position to be determined through its relationship with this fixed reference rather than through direct mechanical connection to the moving air guiding plate.
2Adaptability or versatility
If the air guiding plate is made movable to regulate air direction, then air direction control is improved, but defining the initial position of blades becomes difficult
Solution Approach 1:
The patent resolves this contradiction by inverting the reference frame: instead of trying to define the blade's initial position relative to the moving air guiding plate, it defines the position limiting structure's location relative to the stationary housing. This creates a fixed reference point that remains valid regardless of the air guiding plate's position.
Solution Approach 2:
The patent segments the positioning function from the air guiding function. The position limiting structure is separated as an independent element mounted on the housing rather than being integrated into the moving air guiding plate. This segmentation allows the air guiding plate to move freely for direction regulation while the position limiting structure independently defines the initial position reference.
