Air Vent Louver Adjustment With Single-Motor Dual-Axis Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air vent devices require a large number of components and complex operating movements for adjusting slats, both in mechanical and electrical systems, leading to increased installation space and costs.
Innovation Solution
A device with a first rotatably mounted adjustment element and a second adjustment element, where the axis of rotation of the second element is at a right angle to the first, allowing both slats to be pivoted using a single adjustment mechanism, reducing the number of components and simplifying the adjustment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple actuators and kinematic components are used to adjust horizontal and vertical louvers independently, then the adjustment precision and control flexibility are improved, but the device complexity and installation space requirements increase
Solution Approach 1:
The patent combines the adjustment mechanisms for horizontal and vertical louvers into a single integrated actuator system. The actuator housing contains both horizontal and vertical adjustment mechanisms, allowing one actuator to control both louver orientations simultaneously, thereby reducing the total number of components while maintaining adjustment precision
Solution Approach 2:
The single actuator is designed with multi-functional capability to adjust both horizontal and vertical louvers. The actuator housing serves multiple functions: it houses the motor, contains guides for both horizontal and vertical displacement elements, and provides mounting structures for both louver adjustment mechanisms, making one component perform the work of multiple separate actuators
2Adaptability or versatility
If multiple actuators are used for horizontal and vertical louver adjustment, then the control flexibility is improved, but the installation space requirements increase
Solution Approach 1:
The patent merges multiple actuator functions into a single compact actuator housing that contains both horizontal and vertical adjustment mechanisms, significantly reducing the installation space required while maintaining the ability to independently control both louver orientations
Solution Approach 2:
The design nests the vertical adjustment mechanism within the horizontal adjustment mechanism structure. The actuator housing contains guides for both horizontal and vertical displacement elements, with the vertical guide positioned within the structure of the horizontal guide, creating a space-efficient nested arrangement
3Device complexity
If a single actuator is used to adjust both horizontal and vertical louvers, then the device complexity and installation space are reduced, but the number of operating movements required increases
Solution Approach 1:
The patent employs dynamic adjustment mechanisms where the actuator can operate in multiple modes: rotating to adjust horizontal louvers, translating vertically to adjust vertical louvers, and combining both movements for diagonal airflow direction control. This dynamic operation reduces the total number of separate operating movements needed compared to fixed-mode multi-actuator systems
