Air deflector drive means and indoor air-conditioning unit using drive means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing air deflector drive means in indoor air-conditioning units suffer from poor stability of the connecting rod during telescoping movement, leading to unstable operation of the air deflector.
Innovation Solution
The air deflector drive means incorporates a limiting structure within the drive case, comprising pillars and rolling members with limiting grooves, and chute guide rails to restrict the connecting rod's displacement in all directions, ensuring it moves along a preset trajectory, thereby stabilizing its operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the connecting rod is made slidable in the drive case without limiting structure, then the structure is simple and easy to manufacture, but the stability of the connecting rod during telescoping movement deteriorates
Solution Approach 1:
The drive case is divided into multiple functional regions: a sliding region that allows the connecting rod to move, and a limiting region that constrains displacement in perpendicular directions. This segmentation enables the connecting rod to achieve both easy sliding movement and stable positioning without requiring complex manufacturing processes.
Solution Approach 2:
Limiting members are introduced as intermediary components between the connecting rod and the drive case. These limiting members act as mediators that restrict the connecting rod's displacement in directions perpendicular to its moving direction, thereby improving stability without interfering with the sliding motion.
2Stability of the object's composition
If limiting members are added to restrict connecting rod displacement, then the stability of the connecting rod improves, but the device complexity increases
Solution Approach 1:
The limiting members are integrated into the drive case structure, merging the limiting function with the existing housing. This combination approach adds minimal complexity while achieving the stability improvement, as the limiting members become part of the overall drive case assembly rather than separate附加 components.
Solution Approach 2:
The drive case is designed to serve multiple functions simultaneously: it provides the sliding region for motion, houses the limiting members for stability, and maintains the overall structural support. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
