Vehicle air vent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle air vents experience air loss and vortex formation due to the cut shape of the main wing, which disrupts the airflow direction set by the user's manipulation, leading to inefficient air distribution.
Innovation Solution
A vehicle air vent design featuring a duct, a rotatable front wing, a rear wing, a knob unit, and a guide unit with a curved rod and moving plates that work in conjunction with the knob unit to maintain airflow direction without cutting the main wing, ensuring smooth air guidance and preventing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the main wing is cut to avoid interference with the knob unit rotation, then the knob unit can be manipulated, but air loss and vortex formation occur
Solution Approach 1:
The air vent system is divided into separate functional components: the main wing for air guidance, the knob unit for control, and the guide unit with rod for coordination. This segmentation allows each component to perform its function without interfering with others, eliminating the need to cut the main wing while preserving air flow efficiency
Solution Approach 2:
The guide unit with the curved rod acts as an intermediary mechanism between the knob unit and the main wing. It translates the rotational movement of the knob unit into coordinated movement of the main wing, allowing both the knob unit to be manipulated and the main wing to maintain its full shape for proper air guidance
2Ease of operation
If the main wing is cut to accommodate the knob unit, then the knob unit can rotate, but vortex phenomenon occurs disrupting air flow
Solution Approach 1:
By separating the control function (knob unit) from the air guidance function (main wing) through the guide unit intermediary, the main wing maintains its continuous shape without cuts, thereby preventing vortex formation while still allowing knob unit rotation
Solution Approach 2:
The guide unit with curved rod serves as a mediator that coordinates the motion between the knob unit and main wing, enabling the knob unit to rotate without requiring cuts in the main wing, thus eliminating the vortex phenomenon caused by the cut shape
3Ease of operation
If the main wing is cut to allow knob unit movement, then the knob unit can be manipulated, but air guidance efficiency decreases
Solution Approach 1:
The system is segmented into independent functional units where the main wing remains intact for optimal air guidance, while the knob unit and guide unit handle control operations, maintaining both ease of manipulation and high air guidance efficiency
Solution Approach 2:
The guide unit acts as an intermediary that enables knob unit manipulation without compromising the main wing's shape, thereby preserving air guidance efficiency while providing ease of operation

AI summary
The present invention relates to a vehicle air vent improved to maintain an amount of air passing through the inside of a duct without cutting one region of a main wing. A vehicle air vent includes a duct which accommodates air therein and guides a flow of the air, a front wing rotatable toward a side portion of the duct, a rear wing rotated in a direction intersecting a rotation direction of the front wing, a knob unit coupled to the rear wing to determine rotation directions of the front wing and the rear wing, and a guide unit which is disposed in the duct and rotates the front wing in conjunction with movement of the knob unit, wherein the guide unit includes a rod which has a curved shape along a rotational path of the knob unit and is movable toward the side portion of the duct in conjunction with the movement of the knob unit.
