Vehicle Air Vent Layout for Low-Resistance Direction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle air vents suffer from poor ventilation resistance due to the wing knob blocking the outlet and wind collision, leading to inefficient air discharge.
Innovation Solution
The air vent design includes a housing with a front wing module for left-right adjustment, a rear wing module for up-down adjustment, and a manipulation module to control air direction without obstructing the outlet, utilizing pivot gears, assist wings, and link members for smooth wind direction control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wing knob is installed at the front surface of the air vent to adjust wind direction, then the inclination angles of front and rear wings can be adjusted, but the wing knob blocks the outlet causing poor ventilation resistance and wind collision
Solution Approach 1:
The manipulation module is relocated from the front surface (2D plane blocking the outlet) to the side surface of the housing, utilizing a different spatial dimension. This positional change in the third dimension (depth/side placement) allows the control mechanism to operate without interfering with the air discharge path, thus resolving the contradiction between ease of operation and air discharge efficiency
2Productivity
If the manipulation module is moved to the side surface of the housing, then the outlet is no longer blocked and air discharge efficiency improves, but the control mechanism becomes more complex
Solution Approach 1:
The manipulation module components (pivot gear, mid-gear, rear wing gear, link member) are nested within the side surface housing structure. The gears are arranged in a compact nested configuration where the pivot gear meshes with the mid-gear, which in turn meshes with the rear wing gear, allowing complex functionality to be contained within a limited side-mounted space without excessive external complexity
3Device complexity
If a single manipulation module controls both front and rear wings, then the structure is simplified, but the precision of individual wing adjustment may be reduced
Solution Approach 1:
The manipulation module is segmented into distinct functional components: a pivot gear for controlling the front wing module, a mid-gear for transmission, and a rear wing gear for controlling the rear wing module. Each gear segment independently controls a specific wing, allowing precise individual adjustment while maintaining a unified integrated structure that simplifies the overall device

AI summary
An air vent for a vehicle includes a housing provided with an air outlet, a front wing module mounted within the housing and configured to adjust air discharged through the air outlet in left and right directions, a rear wing module mounted within the housing by being spaced apart from the front wing module and configured to adjust air discharged through the air outlet in up and down directions, and a manipulation module connected to the front wing module and to the rear wing module from outside the housing by being spaced apart from the air outlet, and configured to adjust air discharged through the air outlet in left and right or up and down directions.
