Retractable structure for air-conditioning vent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing retractable air-conditioning vent structures require high manufacturing accuracy and precision, and have complex structures that increase transportation and storage costs due to separate packaging of components.
Innovation Solution
A retractable mechanism with connecting plates and brackets that allow for easy assembly and disassembly of the vane into the main body, using a pivoting method with latch plates and a T-shaped spread-open surface for stability and secure operation, reducing the number of components and materials needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the ring structure is used for retractable vent installation, then transportation volume is saved and transportation cost is lowered, but manufacturing and assembling precision requirements increase
Solution Approach 1:
The retractable mechanism is divided into multiple connecting plates distributed uniformly on the main body, each with brackets that can be independently assembled. This segmentation allows each component to be manufactured separately with standard tolerances, then easily assembled together, reducing the overall manufacturing precision requirements while maintaining the compact retractable structure.
Solution Approach 2:
The patent combines the ring structure with the main body through multiple connecting plates and brackets, creating an integrated assembly that can be packaged together. This merging eliminates the need for separate packaging of the ring and main body, reducing packaging volume while the modular connecting plates maintain ease of assembly without requiring high precision.
2Volume of moving object
If the ring structure with open structure is used, then the ring can be compressed into the main body for packaging, but the structure becomes more complicated with more components
Solution Approach 1:
The connecting plates are designed with flexible brackets that can dynamically adjust during assembly and operation. The brackets can be bent and folded to allow the vane to retract into and extend from the main body, providing the necessary dynamic movement without requiring a complex mechanical mechanism with many separate components.
Solution Approach 2:
The brackets are designed as flexible thin-walled structures that can be easily bent and folded. These flexible brackets allow the connecting plates to adapt their configuration during retraction and extension, providing the necessary movement capability while maintaining a simple overall structure that can be compactly packaged.
3Manufacturing precision
If separate packaging of ring and main body is used, then assembly precision requirements are reduced, but transportation and storage costs increase
Solution Approach 1:
The patent merges the ring structure with the main body through the connecting plates and brackets to form a single integrated assembly. This allows all components to be packaged together in one unit, eliminating the need for separate packaging of the ring and main body, thereby reducing transportation and storage costs while the standardized connecting plates maintain reasonable assembly precision requirements.
4Productivity
If multiple connecting plates and brackets are used for retractable mechanism, then assembling efficiency is improved, but the number of components increases
Solution Approach 1:
The retractable mechanism is segmented into multiple identical connecting plates distributed uniformly on the main body. Each connecting plate is a standardized component with the same bracket design, allowing for rapid assembly through repetition. This segmentation into identical modules improves assembling efficiency while keeping each individual component simple and easy to manufacture.

AI summary
A retractable structure for air-conditioning vent has a retractable mechanism capable of retractably installing a vane into an installing hole of a main body. The retractable mechanism includes a plurality of connecting plates on the main body, and an end of the connecting plates is limited on the main body, and the other end of the connecting plate is passed through a plug hole formed on the vane, and each connecting plate has a bracket on a corresponding side, and a middle portion of the bracket is coupled to the connecting plate, and a first bracket portion and a second bracket portion disposed on both sides of the middle portion of the bracket respectively are outwardly protruded and then inwardly bent to form a stopper portion to stop the plug hole from automatically sliding down.
