Louver Linkage Torque Adjustment for Stable Vent Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wind direction adjustment apparatuses for vehicles have limitations in adjusting the operation load of louvers, leading to variations in operational feeling due to individual component differences.
Innovation Solution
A wind direction adjustment apparatus with a link system that allows louvers to pivot in conjunction, featuring an adjustment section with a clamping mechanism and a fastening member to adjust the clamping force, enabling external adjustment of the operation load post-assembly without hindering ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a soft spacer is used to form a bearing hole for supporting a pivoting shaft, then the pivoting torque of the louver is set by sliding resistance, but the operation load of the louver cannot be adjusted after product assembly
Solution Approach 1:
The bearing hole is designed with an adjustable pressing force mechanism that allows the operation load to be dynamically adjusted after product assembly. The pressing force adjusting member enables users to modify the clamping force on the pivoting shaft, thereby changing the sliding resistance and pivoting torque according to actual needs.
Solution Approach 2:
The pressing force of the bearing hole is made adjustable by introducing a pressing force adjusting member. This member can change the physical parameter of pressing force, which directly affects the sliding resistance between the pivoting shaft and bearing hole, thereby adjusting the operation load of the louver after assembly.
2Reliability
If multiple adjustment sections are provided to stabilize operational feeling, then the configuration becomes complex
Solution Approach 1:
The bearing hole and pressing force adjusting member are integrated into a unified structure. The pressing force adjusting member is incorporated within or as part of the bearing hole assembly, allowing adjustment functionality to be combined with the supporting structure, thereby reducing the number of separate adjustment sections while maintaining operational stability.

AI summary
Provided is a wind direction adjustment apparatus that can stabilize an operational feeling of a louver. The wind direction adjustment apparatus includes a plurality of downstream side louvers disposed in a ventilation path, a link that causes downstream side louvers to pivot in conjunction with each other, and a joining section forming an adjustment section that adjusts a pressing force for pressing one of at least one of the downstream side louvers and the link against the other.
