Vehicle Air Vent With Dual-Disk Omnidirectional Air Deflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air vent designs lack a simple and effective mechanism for deflecting air in various directions, limiting the flexibility and directionality of air flow.
Innovation Solution
The air vent incorporates two movable air deflection elements, guided by orthogonal slots and a displacement element with a ball and socket joint, allowing for independent movement in different directions to control the air flow direction through the vent.

Engineering Contradiction Analysis
1Adaptability or versatility
If a single air deflection element is used to deflect air, then the structure is simple, but the air flow direction control is limited
Solution Approach 1:
The air deflection function is segmented into two independent elements (first and second air deflection elements) that can be moved independently in orthogonal directions. This segmentation allows the system to achieve omnidirectional air flow control by combining the deflection effects of both elements, resolving the contradiction between control versatility and structural simplicity.
Solution Approach 2:
The patent introduces a second dimension of deflection by adding the second air deflection element that moves orthogonally to the first element. The first element deflects air in one transverse direction while the second element deflects air in the orthogonal transverse direction, creating two-dimensional deflection capability that enables arbitrary air flow direction control.
2Productivity
If the air channel narrows in a funnel-shaped manner toward the outlet, then the air flow is guided efficiently, but the deflection mechanism space is limited
Solution Approach 1:
The patent applies different geometric characteristics to different sections of the air channel. The funnel-shaped narrowing provides efficient flow guidance in the longitudinal direction, while the transverse cross-section at the deflection element location provides sufficient space for the elements to move orthogonally. This local differentiation of geometric properties resolves the contradiction between flow efficiency and deflection space.
Solution Approach 2:
The air deflection elements are designed to be movable rather than fixed, allowing them to dynamically adjust their positions to control air flow direction. The elements can be positioned at different locations within the channel cross-section, providing flexible space utilization that accommodates both the funnel-shaped flow guidance and the deflection mechanism requirements.

AI summary
Two disks are consecutively disposed transversely to a flow direction in an air vent for a passenger compartment of a motor vehicle, serving as air deflection elements that include mutually intersecting slots, through which a rod that is pivotably mounted in a ball and socket joint passes, so that the air deflection elements can be moved transversely in the air vent by way of the rod. By moving the air deflection elements, an air current through the air vent can be guided to the side, and thus air flowing out of the air vent can be guided obliquely to the side in any arbitrary direction.
