Vehicle Air Vent Wings for Adjustable Discharge Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air vents in vehicles cannot adjust the discharge range of air from air conditioners or heaters, leading to intense air discharge in a limited local area, failing to accommodate individual driver preferences for wind direction and volume.
Innovation Solution
A variable air vent design featuring a housing with a ball housing and adjustable discharge range and amount wings, controlled by first and second knobs with bevel gears, allowing for air discharge in either concentration or dispersion modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the air vent discharges wind in a fixed direction with a fixed discharge range, then the structure is simple and easy to manufacture, but the discharge range is limited and cannot accommodate different driver preferences
Solution Approach 1:
The air vent is divided into multiple independent adjustable wings (first discharge range adjusting wings and second discharge amount adjusting wings) that can be controlled separately. Each wing can be adjusted independently to control different aspects of air discharge, allowing the system to achieve versatile discharge patterns without requiring complete redesign of the entire structure.
Solution Approach 2:
The patent introduces adjustable wings that can change their position and orientation dynamically. The first discharge range adjusting wings can rotate to change the discharge angle, while the second discharge amount adjusting wings can rotate to control the discharge volume. This dynamic adjustability allows the same structure to serve multiple functions for different driver preferences.
2Area of stationary object
If the air vent discharges wind intensively to a local area, then the discharge volume is concentrated and effective, but the discharge range is limited and does not cover broader areas
Solution Approach 1:
The air vent uses multiple separate wings (first discharge range adjusting wings and second discharge amount adjusting wings) that can be positioned independently. This segmentation allows different portions of the discharge opening to be adjusted separately, enabling the system to maintain concentrated discharge in some areas while expanding coverage in others, thus balancing discharge concentration with broader range coverage.
Solution Approach 2:
Different wings can be adjusted to different positions to create locally optimized discharge patterns. For example, some wings can be positioned to maintain concentrated discharge for drivers who prefer intense cooling, while other wings can be adjusted to expand the discharge range for broader coverage, allowing each local area to have optimized discharge characteristics.

AI summary
A variable air vent is provided. The air vent includes a housing that is mounted on a vehicle and has an open center. A ball housing is coupled to the housing and has an inner side surface that is formed in a curved surface. A ball configured has front and rear surfaces opened and a side surface that is inserted into the ball housing in a curved surface form corresponding to the ball housing. A first knob and a second knob are vertically disposed on the front and rear surfaces of the ball and a plurality of discharge range adjusting wings have a first rotating shaft that is integrally formed at one end of a flat plate. A first side of the first rotating shaft is inserted into the ball and a second side thereof includes a first wing gear inserted into the second knob.
