Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air vents for motor vehicle passenger compartments lack an effective air guidance mechanism to direct airflow efficiently to specific sides, leading to suboptimal ventilation.
Innovation Solution
An air vent design featuring a movably arranged air guiding element within an air duct, where the air guiding element can be rotated and pivoted to direct airflow through a free cross-section around a body in the airflow path, enhancing the air guidance effect by controlling the airflow direction and distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If a movable air guiding element is added to direct airflow, then air guidance effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent employs a movable air guiding element that can rotate about an axis extending along the longitudinal direction of the air duct. This dynamic component allows the airflow direction to be adjusted by rotating the guide element to different angular positions, enabling effective air guidance to various sides of the passenger compartment while maintaining a relatively simple overall structure.
2Productivity
If the air guide element directs airflow to one side, then ventilation efficiency is improved, but airflow uniformity deteriorates
Solution Approach 1:
The air guide element is positioned upstream of the flow-through body and directed at an angle to the longitudinal direction of the air duct. This localized guidance approach directs airflow preferentially to a specific circumferential section, creating non-uniform but targeted airflow distribution that improves ventilation efficiency for specific regions of the passenger compartment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively directs airflow to the desired side, improving ventilation efficiency by ensuring air flows through a specific peripheral section while minimizing counter-directional airflow, thus enhancing the air guidance effect.
Implementation Method 1
The air guide element is preferably positioned in the intended flow direction upstream of the body around which the airflow flows and at an angle to one of the longitudinal directions of the air duct, so that it directs the air flowing through the air duct to one side.

AI summary
The invention relates to an air vent (1) for a motor vehicle and proposes a spherical body (6) in which the air flows around at an outlet opening (5) of an air duct (2) and a plate-shaped air guiding element (8) at an angle in the air duct (2) and about a longitudinal axis (10) of the air duct (2) to be rotatable on an inflow side of the body (6) in the flow. The air guide element (8) arranged diagonally in the air duct (2) directs an air flow past the body (6) around which the air flows on one side, which emerges obliquely inwards in the opposite direction from the outlet opening (5). By rotating the air guide element (8) about the longitudinal axis (10) of the air duct (2), the direction in which the air flow emerges obliquely from the outlet opening (5) can be adjusted.
