Air Vent Shifting Piece Buckle Structure for Easy Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automobile air conditioner wind direction adjusting shifting pieces become brittle and prone to breakage due to alternating cold and hot air exposure, and existing installation methods are complex, making them difficult to replace and adjust.
Innovation Solution
An integrally-formed shifting piece body with a shifting fork, shaft pin, and positioning pieces, along with clamping parts and decoration strips, simplifies the mounting and dismounting process and limits the rotating range of the shifting fork, ensuring secure and adjustable air outlet direction control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shifting piece body uses a complex installation mode with separate fixing pieces and multiple assembly steps, then the connection between parts may be more secure, but the operation becomes difficult and the shifting piece is inconvenient to replace
Solution Approach 1:
The patent combines the shifting piece body and fixing pieces into a single integrated component. The fixing pieces are embedded within the shifting piece body cavity, eliminating the need for separate assembly steps. This integration maintains secure connection while enabling simple one-step replacement of the entire shifting piece assembly.
2Adaptability or versatility
If the shifting piece body is designed as a separate component requiring multiple fixing pieces, then the structure may be more adjustable, but the installation combination mode becomes complex and dismount and mount operations become difficult
Solution Approach 1:
The patent merges multiple components (shifting piece body, fixing pieces, and mounting structure) into a single integrated assembly. The fixing pieces are pre-installed within the shifting piece body cavity, creating a unified component that maintains structural adjustability while simplifying installation to a single operation.
3Reliability
If the shifting piece is designed with multiple separate components and fixing pieces, then the connection may be more secure, but the shifting piece becomes inconvenient to replace when dismount and mount are required
Solution Approach 1:
The patent combines all fixing elements and the shifting piece body into a single integrated component. This allows the entire assembly to be replaced as one unit, maintaining secure connections while enabling convenient replacement without requiring separate disassembly of multiple fixing pieces.
