Snap-Fit Air Deflector Assembly for Reliable Air Sweeping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing air conditioner designs suffer from poor assembly reliability and increased production costs due to separate axial arrangements of air sweeping and deflector components, leading to reduced efficiency and a high risk of motor shaft breakage during repeated disassembly.
Innovation Solution
An air deflector assembly with a snap assembly on the air sweeping connecting rod, allowing snap-fitting with the driving structure, and coaxial rotation with the air deflector portion, enhancing assembly reliability and efficiency while reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate axial arrangement methods are used for air sweeping blade and air deflector, then the assembly structure is simplified, but the number of parts increases, cost increases, assembly process increases, and production efficiency decreases
Solution Approach 1:
The patent combines the air sweeping connecting rod and air deflector connecting rod into a single integrated connecting rod structure. This merging reduces the number of separate parts, simplifies the assembly structure, and improves production efficiency by eliminating the need for separate assembly processes for each component.
Solution Approach 2:
The integrated connecting rod serves multiple functions: it acts as both the air sweeping connecting rod and the air deflector connecting rod. This multi-functional design reduces the overall number of components needed in the system while maintaining all necessary operational functions.
2Device complexity
If separate axial arrangement methods are used for air sweeping blade and air deflector, then the assembly structure is simplified, but the cost of the whole machine increases
Solution Approach 1:
By merging the air sweeping connecting rod and air deflector connecting rod into one integrated component, the patent reduces the total number of parts that need to be manufactured, stored, and assembled. This leads to lower manufacturing costs, reduced inventory requirements, and simplified supply chain management.
3Device complexity
If separate axial arrangement methods are used for air sweeping blade and air deflector, then the assembly structure is simplified, but the assembly process increases and reliability decreases
Solution Approach 1:
The integrated connecting rod structure eliminates multiple connection points and assembly interfaces, reducing the opportunities for assembly errors and potential failure points. This merging improves assembly reliability by creating a more robust and fewer-failure-point structure.
4Ease of operation
If repeated disassembly of sweeping blade is performed, then maintenance and adjustment are enabled, but the motor shaft driving the sweeping blade is easy to break due to poor assembly reliability
Solution Approach 1:
The patent designs the integrated connecting rod with separable snap assembly connections that allow easy disassembly and reassembly without stressing the motor shaft. The segmentation is designed at the connecting rod level rather than at the motor shaft level, protecting the critical motor shaft from repeated assembly/disassembly stresses while still enabling maintenance access.
Solution Approach 2:
The snap assembly acts as an intermediary mechanism between the connecting rod and motor shaft, providing a controlled disassembly interface that protects the motor shaft from direct stress during maintenance operations. This intermediary structure allows easy maintenance while preserving motor shaft integrity.

AI summary
The present disclosure provides an air deflector assembly and an air conditioner with the air deflector assembly, it includes a first driving portion, a second driving portion, an air deflector portion and an air sweeping portion, the first driving portion is connected to the air deflector portion, and the air deflector portion driven by the first driving portion is rotatably arranged; the air sweeping portion is located on a side of the air deflector portion, the second driving portion is connected to the air sweeping portion, and the air sweeping portion driven by the second driving portion is rotatably arranged; wherein the air sweeping portion includes an air sweeping connecting rod, the air sweeping connecting rod includes a rod body portion and a snap assembly, the rod body portion is connected to the air deflector portion, the snap assembly is provided at an end portion of the rod body portion, and the snap assembly is snap-fitted with the second driving portion. By arranging the snap assembly on the air sweeping connecting rod of the air sweeping portion and snap-fitted the snap assembly with the second driving portion, the separation of the air sweeping portion from the air deflector portion is realized, so that the service life of the portions is extended, the assembly reliability of the air deflector assembly is enhanced, the production efficiency is improved, and the cost of the whole machine is decreased.
