Vehicle Air Vent Integrating Direction and Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air vents for vehicles require separate components to control air direction and flow, increasing manufacturing costs and complexity.
Innovation Solution
An air vent design that integrates a single part to control air direction and flow, featuring a duct with a first adjuster for side-to-side rotation and a second adjuster connected to a driving unit for up-down rotation and airflow control, along with a flow path guide to direct air to the outlet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate parts are used for controlling air direction and flow, then the control functions are independent and reliable, but the manufacturing cost increases and device complexity increases
Solution Approach 1:
The patent combines the air direction control function and air flow control function into a single integrated adjuster assembly. The first adjuster controls air direction upward/downward while the second adjuster controls air flow, both integrated within one housing structure. This merging reduces the number of separate parts and simplifies the overall device structure while maintaining independent control capabilities for both functions.
2Ease of manufacture
If separate parts are used for controlling air direction and flow, then each part can be optimized for its specific function, but the manufacturing cost increases
Solution Approach 1:
The integrated adjuster assembly serves multiple functions within a single component structure. The housing contains both the first adjuster for air direction control and the second adjuster for air flow control, allowing one assembly to perform what previously required separate components. This multi-functionality reduces manufacturing costs by reducing the number of parts while maintaining the versatility to control both air direction and flow independently.
3Device complexity
If a single part is used to control both air direction and flow, then manufacturing cost is reduced and device complexity is reduced, but the control precision for each function may be compromised
Solution Approach 1:
Within the integrated adjuster assembly, the control functions are segmented into distinct components: the first adjuster for air direction control and the second adjuster for air flow control. Each adjuster can be independently adjusted and controlled, maintaining precision for each specific function while being housed within a single integrated assembly. This segmentation allows precise control adjustment for each function without requiring completely separate external components.

AI summary
An air vent for a vehicle may include: a duct having a passage through which air is moved; a first adjuster rotatably installed in the duct, and configured to guide a discharge direction of air while rotating in a side-to-side direction; a second adjuster rotatably installed in the duct with the first adjuster, and configured to guide a discharge direction of air while rotating in an up and down direction or block an air flow passing through the duct; and a driving unit connected to the second adjuster and configured to supply power to rotate the second adjuster.
