Motor-driven air vent device for vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle air vents require manual angular rotation of horizontal wings for vertical airflow adjustment, which compromises driving safety and design flexibility due to the need for direct driver operation and large size, while slim type vents lack convenient vertical adjustment and occupy less space but are difficult to operate safely.
Innovation Solution
A motor-driven air vent system with a link structure connecting a horizontal wing to a driving motor, allowing vertical angular rotation via a touch switch operation, enabling automatic adjustment of airflow direction without manual wing operation, thus improving safety and design freedom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual angular rotation of horizontal wings is used for vertical airflow adjustment, then the driver can directly control airflow direction, but driving safety decreases due to temporary inability to look ahead
Solution Approach 1:
The patent replaces the manual mechanical rotation system with an automated motor-driven system. The motor rotates the horizontal wing module in response to switch signals, eliminating the need for the driver to manually grasp and rotate the wing while driving, thus maintaining driving safety while enabling airflow adjustment control.
Solution Approach 2:
The system enables self-service operation where the airflow adjustment is automatically performed by the motor-driven mechanism in response to simple switch activation. The driver only needs to activate the switch rather than manually manipulate the wing, making the system serve itself for the adjustment task.
2Ease of operation
If conventional air vent with multiple horizontal wings and vertical wings is used, then vertical airflow adjustment is achievable, but the air vent size becomes large affecting package space
Solution Approach 1:
The patent segments the air vent into distinct functional modules: a horizontal wing module for vertical airflow adjustment and a vertical wing module for horizontal airflow adjustment. This segmentation allows each module to be optimized independently, enabling the horizontal wing module to achieve vertical adjustment functionality in a more compact form compared to conventional designs that required multiple overlapping wings.
Solution Approach 2:
The patent introduces rotational movement in the vertical dimension for the horizontal wing module, allowing it to pivot and adjust airflow direction upward or downward. This dimensional change enables vertical airflow control without requiring the air vent to occupy large horizontal mounting space, as the adjustment occurs through rotation rather than through multiple static wing elements.
3Area of moving object
If slim type air vent with single horizontal wing is used, then mounting space is reduced and design freedom is improved, but vertical airflow adjustment becomes inconvenient
Solution Approach 1:
The patent replaces the manual mechanical adjustment system with an automated motor-driven system. The motor rotates the single horizontal wing module in response to switch signals, eliminating the need for the driver to manually grasp and rotate the wing. This substitution maintains the compact slim design while restoring convenient airflow adjustment control through automation.
Solution Approach 2:
The system enables self-service operation where the compact single horizontal wing module automatically performs vertical airflow adjustment in response to switch activation. The motor-driven mechanism serves the adjustment function autonomously, making the slim design as convenient to operate as larger conventional vents.
4Reliability
If motor-driven system with link structure is used for horizontal wing rotation, then driving safety is improved by eliminating manual operation, but device complexity increases
Solution Approach 1:
The patent substitutes complex manual manipulation mechanisms with a simpler motor-driven system. Instead of requiring manual grasping and rotation of the horizontal wing module, a motor connected through a link structure performs the rotation automatically. This substitution reduces operational complexity for the user while maintaining mechanical simplicity through direct motor-to-wing connectivity via the link mechanism.

AI summary
A motor-driven air vent device for a vehicle is provided. The motor-driven air vent device connects a horizontal wing of an air vent to an output shaft of a driving motor through a link structure and rotatably operates the driving motor in the forward direction or the reverse direction by a touch type switch operation. Accordingly, the vertical angular rotation operation for the horizontal wing is automatically performed by the operation of the link structure delivering the torque of the driving motor.
