Infotainment-Controlled Air Vent Assembly for Split Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air vent assemblies in HVAC systems lack intuitive control options and are often dependent on physical input devices, which can be unreliable, and they do not provide sufficient flexibility in airflow direction to ensure driver and passenger comfort.
Innovation Solution
An air vent assembly with elongated vent portions controlled by a single rotary actuator and an infotainment system, allowing users to customize airflow direction through menu options on a user interface, enabling leftward, rightward, onward, and split airflow configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional physical buttons and knobs are used to control air vent assemblies, then the control mechanism is simple and reliable, but the user interface lacks intuitiveness and flexibility
Solution Approach 1:
The patent replaces physical mechanical controls (buttons and knobs) with an electronic control system that uses a touchscreen display and software interface. This substitution allows for more intuitive graphical user interfaces, customizable control options, and integrated climate management without the physical space constraints of mechanical components.
2Adaptability or versatility
If multiple separate vents are provided for driver and passenger, then airflow flexibility is improved, but dashboard space is consumed
Solution Approach 1:
The patent divides the airflow control into separate controllable zones within the vent assembly, allowing independent adjustment of airflow direction for different occupants. The vent assembly includes multiple adjustable vanes that can be independently controlled to direct airflow to different locations, providing the flexibility of multiple vents while maintaining a compact integrated structure.
Solution Approach 2:
The integrated vent assembly serves multiple functions: it provides airflow to both driver and passenger, allows independent directional control for each occupant, and can be controlled through a unified electronic interface. This multi-functionality consolidates what would traditionally require separate physical vents and controls into a single space-efficient unit.
3Reliability
If traditional air vent assemblies are used, then the structure is simple, but the reliability of HVAC system operation is insufficient
Solution Approach 1:
The patent incorporates sensors that detect airflow conditions, temperature, and occupancy to automatically adjust vent positions and airflow distribution. This feedback mechanism ensures the HVAC system maintains optimal performance and reliability by continuously monitoring and adjusting to changing conditions without requiring manual intervention.
Solution Approach 2:
The vent assembly includes automatic control features that adjust airflow distribution based on detected conditions, reducing dependence on manual operation and ensuring consistent reliable performance. The system can automatically compensate for failures or suboptimal settings, maintaining HVAC functionality under varying operating conditions.

AI summary
An air vent assembly includes a cover member having an inlet for allowing a flow of air to enter the cover member. The cover member also has a vent extending from the inlet for allowing a flow of air to exit the cover member. The vent includes a first vent portion, and a second vent portion located adjacent to the first vent portion. The first vent portion has a first set of flow guiding vanes disposed therein. The second vent portion has a second set of flow guiding vanes disposed therein. Each of the vanes is spaced apart from one another and pivotally coupled to a pair of opposing walls of the cover member. The first and second sets of flow guiding vanes are independently moveable with respect to each other using an actuating mechanism for providing a variety of flow-guiding positions one of which includes a split flow-guiding position.
