Automotive Air Nozzle With Hidden Slat Control for Uniform Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air nozzles for motor vehicles fail to provide a pleasant air flow distribution and an attractive design, as they often have visible slats that protrude and do not allow for uniform airflow direction adjustment.
Innovation Solution
The air nozzle features rotatably mounted slats coupled by lateral coupling rods, with a central control lamella and an actuating element accessible through a cover mask, allowing for hidden slat adjustment and diffused airflow via a ring guide and adjusting ring with operable elements, enabling uniform airflow distribution and improved aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If slats are made visible and protruding for adjustment, then airflow direction control is achieved, but aesthetic appearance deteriorates
Solution Approach 1:
The slats are extracted from the visible front area and relocated to the rear part of the housing. The rear housing contains the slats that can be adjusted independently, while the front housing presents a clean, aesthetic appearance without protruding adjustment elements. This separation allows airflow control functionality to be maintained while eliminating the visual defect.
2Ease of manufacture
If slats are fixed in position, then manufacturing simplicity is improved, but airflow distribution uniformity deteriorates
Solution Approach 1:
The housing is segmented into a front housing and a rear housing that can be adjusted independently. The rear housing contains the slats that can be pivoted to different positions, allowing airflow distribution to be optimized without complicating the overall manufacturing process. The segmentation enables independent adjustment of the rear housing relative to the front housing.
3Adaptability or versatility
If slats are made adjustable with multiple components, then airflow direction flexibility is improved, but device complexity increases
Solution Approach 1:
The slats are merged with the rear housing to form an integrated assembly that can be adjusted as a unit. The coupling rod connects the slats to the rear housing, allowing them to move together while maintaining a relatively simple structure. This merging reduces the number of separate components compared to having independently adjustable slats within the front housing.

AI summary
The invention relates to an air nozzle for conducting an air flow out of an air supply shaft or a pipe from a heating, ventilating or air conditioning system, in particular in a motor vehicle, with a housing which has a connection on the rear side for the air supply shaft and an air outlet opening on the front side. The air outlet opening contains air-guiding elements having slats which are adjustable via a coupling rod. The axes (4) of the individual slats (5) are arranged in a slat ring (2) having one or two lateral coupling rods (3), wherein the central slat (5) is designed as a control slat and has an actuating element (6) for adjusting the slats (5). The slat ring (2) is inserted with the slats (5) in an annular guide (7) in the receptacle (1) and is coupled to an adjusting ring (8) which is mounted rotatably in the annular guide (7) and the outer circumference of which has operating elements (9) for rotating the slat ring (2). The opening of the adjusting ring (8) contains a covering mask (10) having a central aperture through which the actuating element (6) for the slats (5) is accessible or from which the actuating element operably protrudes.
