Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air vents with multiple horizontal and vertical wings occupy large mounting spaces, limiting design freedom and aesthetics, and are unable to easily adjust airflow direction due to their bulky structure.
Innovation Solution
A slim-type air vent design featuring a vane device with rotatable components controlled by a knob, allowing easy adjustment of airflow direction through a hinge mechanism, comprising a duct, vane links, and a knob for rotating the vane device to change airflow channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple horizontal and vertical wings are used to control airflow direction, then airflow adjustment capability is improved, but the size of the air vent increases
Solution Approach 1:
The air vent is divided into separate functional components: a fixed slim housing and a rotatable vane assembly that can independently adjust airflow direction. This segmentation allows the main body to remain compact while the movable vanes provide directional control.
Solution Approach 2:
The patent introduces a rotatable vane assembly with multiple vanes that can dynamically adjust their orientation relative to the airflow. The vanes are connected to a knob mechanism that allows users to change the airflow direction by rotating the vanes, providing adaptability without increasing the overall air vent size.
2Area of stationary object
If a slim duct with a single horizontal wing is used, then the air vent size is reduced, but airflow direction adjustment capability deteriorates
Solution Approach 1:
The patent transforms the static single-wing design into a dynamic multi-vane system. The rotatable vane assembly includes multiple vanes that can be independently positioned to control airflow in different directions, enabling the slim air vent to achieve adjustable airflow control despite its compact size.
Solution Approach 2:
The patent adds a rotational dimension to the airflow control mechanism. Instead of relying solely on the orientation of a single horizontal wing, the rotatable vane assembly introduces a new degree of freedom, allowing airflow direction to be adjusted by rotating the vanes around the airflow axis, thereby enhancing control capability within a compact form factor.
3Adaptability or versatility
If multiple horizontal and vertical wings are exposed, then airflow control is improved, but mounting space requirement increases
Solution Approach 1:
The air vent is segmented into a fixed mounting housing and a separate rotatable vane assembly. This segmentation allows the housing to be compact and minimally invasive to the dashboard, while the vane assembly provides the necessary airflow control functionality through rotation, reducing the overall mounting space requirement.
Solution Approach 2:
The patent replaces the static multiple-wings structure with a dynamic rotatable vane assembly. The vanes can be rotated to achieve different airflow directions, providing equivalent or superior airflow control to multiple fixed wings while occupying less mounting space due to the compact rotational mechanism.
4Adaptability or versatility
If a slim duct design is used, then design freedom is improved, but aesthetics deteriorate due to limited airflow adjustment
Solution Approach 1:
The patent enhances the aesthetic appeal of the slim duct design by incorporating a rotatable vane assembly with a decorative knob. The knob provides a tactile and visual element that complements the slim design, while the rotatable vanes inside allow for airflow adjustment, combining aesthetic appeal with functional adaptability.
Solution Approach 2:
The rotatable vane assembly serves multiple functions: it controls airflow direction, provides a decorative element through the knob, and maintains the compact slim profile. This multi-functionality allows the air vent to achieve both design freedom and aesthetic appeal simultaneously, as the same mechanism that enables airflow adjustment also contributes to the overall design aesthetics.

AI summary
The present invention relates to a slim-type air vent of a vehicle. More specifically, the present invention can easily change a flow channel of air, which is discharged toward an exit through an outflow part of a duct, by means of each rotation relative to a hinge, according to a rotation state of a knob. The present invention comprises: a duct having an inflow part through which air is introduced and an outflow part enlarged compared with the inflow part and formed to communicate therewith; a vane device for controlling the direction and the volume of the air discharged through an exit formed in the outflow part of the duct; and a knob for providing a driving force such that the vane device rotates about a hinge.
