Solution Overview
Problem
Existing air vent designs for vehicle interiors are complex and lack flexibility in airflow direction adjustment, often requiring multiple fins and movable surfaces, which increases assembly costs and complicates maintenance.
Innovation Solution
A simple outlet device with a housing featuring an outer and inner air guide surface forming a continuous flow channel, an airflow adjustment member, and a guiding device that allows the adjustment member to move across the housing axis, altering the ratio of air flow components and directing the outlet flow by obstructing one or both circumferential sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple fins and movable surfaces are used for airflow direction adjustment, then airflow direction control is improved, but device complexity increases
Solution Approach 1:
The outlet device is divided into two independent circumferential sections (first and second sections) that can be independently adjusted. Each section has its own airflow adjustment member that can be moved separately by the user, allowing independent control of airflow from each section. This segmentation enables simplified adjustment mechanism while achieving versatile airflow direction control.
Solution Approach 2:
The outlet device incorporates movable airflow adjustment members that can dynamically change the flow area of each circumferential section. By moving these adjustment members, users can dynamically control the airflow direction and distribution ratio between the two sections, providing operational flexibility without complex fixed structures.

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
This design allows for adjustable airflow direction based on the relative flow rates of channel sections, reducing the need for multiple fins and movable parts, simplifying assembly and maintenance while maintaining a clean external appearance.
Implementation Method 1
the directions of the first circumferential section and the second circumferential section meet each other in an intersection point which lies outside the housing at the side of the air outlet orifice, so that, caused by an inlet air flow which passes the air inlet orifice, a first air flow component flowing through the first circumferential section and a second air flow component flowing through the second circumferential section deflect each other after exiting the housing
Implementation Method 2
an airflow adjustment member which has a cross-sectional diameters perpendicular to the housing axis each of which is smaller than the cross-sectional diameter of the outlet flow channel at the same position of the housing axis in the same direction, and which is movable in a direction across the housing axis for obstructing an air flow in one of the first or second circumferential section

AI summary
An outlet device (1) for ventilation of a vehicle interior has a housing (H) with an outer air guide surface (10a), and inner guide surface (30a), a guiding device (G), and an airflow adjustment member (63). The inner and outer air guide surfaces form an outlet flow channel (22) which extends between an air inlet orifice (11) and an air outlet orifice (12). The outlet flow channel (22) includes a first circumferential section (23a) and a second circumferential section (23b). An inlet air flow which passes the air inlet orifice (11) produces a first air flow component flowing therethrough and the second circumferential section (23b) produces a second air flow component flowing therethrough. The directions of the first and second circumferential sections meet each other in an intersecting point (P) which lies outside the housing (H). The airflow adjustment member allows changes to the ratio of the volumetric flows of the intersecting first and second air flow components.
