Automobile Air Vent Single Knob Vane Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automobile air vents require significant space due to multiple vanes for adjusting air direction, limiting their size and installation flexibility, making it difficult to achieve desired interior designs.
Innovation Solution
An air vent system with a single knob that adjusts wind directions leftward and rightward, upward and downward, using a vane driving device and damper mechanism to minimize installation space and allow for a slim, reduced size, enabling flexible installation and design within the automobile interior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple vanes are installed to adjust air direction, then wind direction control capability is improved, but device size and installation space increase
Solution Approach 1:
The patent combines multiple vane functions into a single integrated vane structure. Instead of using separate vanes for horizontal and vertical air direction adjustment, the invention uses one vane that can be positioned at different angles to achieve both horizontal and vertical air flow control, thereby reducing the number of components and minimizing device size while maintaining full wind direction control capability
Solution Approach 2:
The single vane in the patent serves multiple functions: it controls both horizontal air direction and vertical air direction, and also functions as an opening/closing mechanism when positioned at specific angles. This multi-functional design eliminates the need for separate control mechanisms for each function, reducing overall device complexity and size
2Adaptability or versatility
If separate vane link is provided for vertical wind direction adjustment, then wind direction control is improved, but device complexity and size increase
Solution Approach 1:
The patent merges the vertical wind direction control function into the same vane mechanism used for horizontal control. The single vane rotates around a central axis to achieve both horizontal and vertical positioning, eliminating the need for a separate vane link mechanism and significantly simplifying the overall structure
Solution Approach 2:
Instead of using multiple vanes that move in different directions, the patent inverts the approach by using a single vane that rotates around a vertical axis, allowing the vane itself to change orientation in both horizontal and vertical planes through rotational movement, thereby eliminating complex link mechanisms
3Adaptability or versatility
If multiple vanes are installed, then air direction adjustment capability is improved, but manipulation space and installation space increase
Solution Approach 1:
The patent consolidates multiple air direction adjustment functions into a single vane component. This single vane can be positioned at various angles to control air flow in different directions, replacing what would traditionally require multiple separate vane components and their associated mounting spaces, thereby minimizing the overall installation area

AI summary
Provided is an air vent for an automobile having a duct having a passage, a knob mount coupled to the duct, a knob installed to the knob mount, first and second vane members installed to the knob mount, a vane driving device installed to the knob mount, and a damper installed in the duct. The knob is movable leftwards and rightwards and is rotatable upwards and downwards. The first vane member is rotated upwards and downwards by the vane driving device when the knob is rotated upwards and downwards. The second vane member is rotated leftwards and rightwards by the vane driving device when the knob is moved leftwards and rightwards. The vane driving device transmits the rotation of the knob to the first vane member, and transmits the movement of the knob to the second vane member. The damper opens or closes the passage by rotation.
