Motor Vehicle Air Vent With Single-Motor Vane Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor-driven air vents for vehicle compartments require two motors, leading to high manufacturing costs and significant electrical energy consumption, and manual control can lead to driver distraction and accidents.
Innovation Solution
A single motor system controls the movement of air guide elements pivoting around vertical and horizontal axes, using a single motor to adjust airflow direction and temperature via a control unit, reducing costs and energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two motors are used to control two rows of air guide vanes, then regulated control of airflow direction is achieved, but manufacturing costs and electrical energy consumption increase
Solution Approach 1:
The patent combines the functions of two separate motors into a single motor system. The first and second air guide vanes are both connected to a single operating member that rotates about a vertical axis, allowing one motor to control both rows of vanes simultaneously through mechanical linkage, thereby reducing electrical energy consumption and manufacturing costs while maintaining regulated airflow control
Solution Approach 2:
The single operating member serves multiple functions by controlling both the first air guide vanes (pivoting horizontally) and the second air guide vanes (pivoting vertically). This multi-functional design allows one motor to achieve what previously required two separate motor systems, reducing overall system complexity and energy consumption
2Ease of operation
If two motors are used to control air guide vanes, then precise airflow regulation is achieved, but manufacturing costs increase
Solution Approach 1:
The patent merges two motor-driven control systems into a single motor system with an operating member that mechanically links to both air guide vane rows. This consolidation reduces the number of motors and control components needed, directly lowering manufacturing costs while preserving precise airflow regulation capability through the coordinated movement of both vane rows
3Device complexity
If manual control is used for air vents, then system simplicity is maintained, but driver distraction and accidents may occur
Solution Approach 1:
The system provides self-service automation where the motor automatically adjusts the air guide vanes based on pre-defined trajectories or sensor input, eliminating the need for manual driver intervention. This autonomous operation reduces driver distraction and improves safety while the system handles airflow regulation independently
Solution Approach 2:
The patent incorporates sensors that detect airflow characteristics and provide feedback to the control system, which then automatically adjusts the operating member position to optimize airflow. This closed-loop feedback mechanism enables automatic adaptation without driver input, enhancing safety by removing manual control requirements
