Slim Vehicle Air Vent With Constant-Airflow Wing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle air vents have a high vertical height, poor aesthetics due to protruding outer wings, and inconsistent air volume discharge, which affects performance and appearance.
Innovation Solution
A slim air vent design where the inner, outer, and support wings are housed within a duct, with a link mechanism and knob pin system that allows vertical rotation of outer wings without changing the cross-sectional area, maintaining constant air volume and improving appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If outer wings are made to rotate in the vertical direction to control air direction, then air direction control is improved, but the vertical height of the air vent increases and the appearance deteriorates
Solution Approach 1:
The outer wings are nested inside the duct rather than protruding outward. The rotation mechanism is contained within the duct structure, allowing the outer wings to rotate vertically for air direction control while maintaining a compact vertical height and improving appearance.
2Ease of operation
If outer wings rotate in the vertical direction to change air discharge direction, then air direction control is improved, but the cross-sectional area of the outlet changes and air volume discharge becomes inconsistent
Solution Approach 1:
The duct cross-sectional area is designed to remain constant while the inner wings and outer wings rotate locally to change air discharge direction. This local rotation capability allows air direction control without affecting the overall outlet cross-sectional area, maintaining consistent air volume discharge.
3Length of stationary object
If multiple wings are disposed inside the duct to improve appearance and reduce height, then compactness is improved, but the device complexity increases
Solution Approach 1:
The inner wings and outer wings are combined in a nested arrangement inside the duct, with both sets of wings working together to control air discharge direction. This merging of multiple wing elements into a compact nested structure reduces the vertical height and improves appearance while managing the complexity through integrated design.

AI summary
A slim air vent for a vehicle includes an inner wing disposed in a duct to horizontally rotate during manipulation of a knob, an outer wing and a support wing disposed in the duct to vertically rotate during the manipulation of the knob, a knob pin horizontally penetrating through the knob to rotate together with the knob during the vertical rotation of the knob and to guide the knob during the horizontal movement of the knob, and a link mechanism provided to connect one end of the knob pin and the outer wing to vertically rotate the outer wing and the support wing during rotation of the knob pin according to the vertical rotation of the knob.
