Air Register Actuation Layout for Multi-Direction Airflow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air-conditioning register systems require multiple actuators to adjust airflow direction, leading to a complex and larger structure, which complicates the adjustment mechanism and increases size.
Innovation Solution
The air-conditioning register incorporates a retainer with movable members and a single actuator that utilizes conversion mechanisms to convert rotation into motion in multiple directions, actuating the movable members to adjust airflow direction without the need for multiple motors, thereby simplifying the structure and reducing size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple actuators are used to adjust airflow direction vertically and laterally, then the airflow direction control capability is improved, but the device complexity and size increase
Solution Approach 1:
The patent combines multiple actuators (vertical actuator and lateral actuator) into a single integrated actuator unit. The actuator case houses both actuators, and the common support structure provides a unified mounting platform, merging previously separate components into one compact assembly that reduces overall device complexity while maintaining full airflow direction control capability
Solution Approach 2:
The common support structure serves multiple functions: it supports both the vertical and lateral actuators, provides mounting surfaces for multiple louvers, and acts as a structural framework for the entire airflow direction control mechanism. This multi-functional design eliminates the need for separate support structures for each actuator, thereby reducing device complexity
2Adaptability or versatility
If multiple actuators are used to adjust airflow direction, then the airflow direction control capability is improved, but the device size increases
Solution Approach 1:
The patent implements a nested arrangement where the lateral actuator and vertical actuator are housed within the actuator case, with the common support structure providing internal mounting surfaces. The louvers are nested within the housing and connected to the actuators through the support structure. This nesting arrangement allows multiple components to occupy overlapping spatial volumes, significantly reducing the overall device size while maintaining full control capability

AI summary
An air-conditioning register includes a retainer that forms a vent passage for air-conditioning air, multiple movable members that are attached to the retainer and movable in different directions, an actuator that rotates to actuate the movable members, and multiple conversion mechanisms that convert rotation of the actuator into motion in directions in which the movable members move, thereby actuating the movable members.
