Slim Vehicle Air Vent With Hidden Wings and Constant Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle air vents have a large vertical height, an unattractive appearance, and variable airflow discharge due to externally projecting wings, leading to performance deterioration and aesthetic issues.
Innovation Solution
A slim air vent apparatus with internal and external wings, and support wings positioned inside a duct, allowing vertical rotation without projecting externally, maintaining a constant cross-sectional area for consistent airflow and reducing vertical height for a compact, luxurious appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external wings are disposed vertically and project outwards from the duct, then the air vent can discharge air in vertical and horizontal directions, but the vertical height and horizontal length of the air vent increase
Solution Approach 1:
The external wings are nested inside the duct rather than projecting outward. The support wings extend from the duct lateral sides to support the external wings within the duct space, creating a compact structure that maintains airflow control functionality while reducing the overall vertical height and horizontal length of the air vent assembly.
2Ease of operation
If external wings project outwards from the duct, then the air vent can rotate vertically to control airflow direction, but the appearance becomes unattractive and the structure is exposed
Solution Approach 1:
The external wings are positioned inside the duct and do not project outward, creating a sleek, streamlined appearance. The support wings provide structural support from within the duct, keeping all moving components hidden within the duct boundaries while maintaining full rotational functionality for airflow direction control.
3Ease of operation
If the cross-sectional area of the outlet is varied by vertical rotation of external wings, then the airflow direction can be controlled, but the amount of discharged air varies and performance deteriorates
Solution Approach 1:
The air vent system is segmented into multiple functional components: internal wings for horizontal airflow control, external wings for vertical airflow control, and support wings that maintain structural integrity. This segmentation allows each component to perform its specific function without interfering with the overall outlet cross-sectional area, maintaining consistent airflow discharge while enabling directional control.
4Length of stationary object
If multiple wings are disposed inside the duct, then the vertical height is reduced and appearance is improved, but the device complexity increases
Solution Approach 1:
Multiple wings (internal wings and external wings) are nested within the duct space, with support wings providing structural support from the duct lateral sides. This nesting arrangement consolidates multiple components within the existing duct boundaries, reducing the overall vertical height and improving appearance while the modular support wing structure helps manage the complexity of coordinating multiple moving parts.

AI summary
A slim air vent apparatus for a vehicle may include an internal wing, an external wing, and a support wing that are disposed and hidden inside a duct to realize a compact and slim air vent apparatus and to improve the appearance by hiding the components. Since the air vent is operated to fulfil the functions thereof by manual manipulation of a single knob, positioned at the center portion of the external wing, by a user, it is possible to improve the convenience in manipulation of a user and to reduce manufacturing costs, and the air vent is universally applicable to various kinds of vehicles.
