Ceiling Indoor Unit Vane Linkage for Faster Discharge Vane Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling type indoor units of air conditioners require the entire front panel to be separated to repair or replace a broken discharge vane, which is inefficient and time-consuming.
Innovation Solution
A ceiling type indoor unit design that allows simultaneous control of first and second vanes through a rotating driving link, enabling different rotational angles to be formed using a single vane motor, with the driving link coupled to the vane motor and featuring a core link shaft, first and second driving link shafts, and vane links for independent rotation and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the entire front panel is separated to repair or replace a broken discharge vane, then the discharge vane can be accessed and replaced, but the repair time and complexity increase significantly
Solution Approach 1:
The front panel is divided into multiple detachable front vanes (first vane, second vane, third vane, fourth vane) that can be independently removed from the case. Each vane is connected through a modular linkage system (driving link, vane link) that allows individual access to any single vane without removing the entire front panel assembly, thereby reducing repair time and complexity
2Device complexity
If multiple vanes are controlled by a single vane motor through a driving link mechanism, then the device complexity is reduced, but the control precision and ability to form different rotational angles may be compromised
Solution Approach 1:
A single vane motor is designed to control multiple vanes (first, second, third, and fourth vanes) through a universal driving link mechanism. The driving link can rotate about a central axis and connect to different vanes via vane links, allowing one motor to perform the function of controlling multiple vanes independently, thus reducing device complexity while maintaining control capability
Solution Approach 2:
The driving link is designed as a dynamic component that can rotate about a central axis and change its orientation to connect with different vanes. The vane links are configured to allow relative rotation between the driving link and each vane, enabling each vane to achieve different rotational angles independently while being driven by the same motor, thus maintaining control precision through dynamic adjustment
