Concealed Air Nozzle Blade Ring for Diffuse Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air nozzles in motor vehicles and similar applications often have visible blades that protrude, leading to an unpleasing design and inefficient air flow distribution, as they are fixed in direction and strength.
Innovation Solution
The air nozzle design features rotatably mounted blades in a blade ring, coupled by lateral coupling rods, with a control blade and actuating element for adjustment, and a cover mask or atomiser ring that conceals blade adjustment and enhances air flow distribution by swirling it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If blades are made visible and protruding for adjustment, then ease of operation is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The actuating element for blade adjustment is extracted and positioned on the rear side of the nozzle housing, separated from the visible front surface. This allows the adjustment mechanism to be accessible and operable while being hidden from view, resolving the contradiction between ease of operation and aesthetic appearance.
Solution Approach 2:
A coupling rod serves as an intermediary mechanism that transmits the adjustment motion from the actuating element to the blades. This allows the adjustment function to be implemented without requiring visible protruding blades, maintaining aesthetic appearance while preserving operational capability.
2Device complexity
If blades are fixed in direction, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The blades are designed to be rotatable about their longitudinal axes, transforming from a fixed static configuration to a dynamic adjustable one. This allows the air flow direction to be adapted to different requirements while maintaining a relatively simple mechanism through the use of rotation rather than complex positioning systems.
3Ease of operation
If blades are arranged to protrude for adjustment, then ease of operation is improved, but air flow distribution deteriorates
Solution Approach 1:
The nozzle is segmented into multiple blade elements that can be independently adjusted. This segmentation allows each blade to be positioned optimally for air flow distribution while maintaining accessibility through the rear-mounted actuating mechanism, resolving the contradiction between operational ease and flow distribution efficiency.

AI summary
The invention relates to an air nozzle for conducting air flow from an air feed shaft or a duct from a heating, ventilating or air-conditioning installation, particularly in a motor vehicle, with a housing having a connection at the back for the air feed shaft and an air outlet opening at the front. Air guide elements with blades adjustable by way of a coupling rod are present in the air outlet opening. The axles (4) of the individual blades (5) are arranged in a blade ring (2) with one lateral coupling rod (3) or two lateral coupling rods (3), wherein the middle blade (5) is constructed as a control blade and has an actuating element (6) for adjusting the blades (5). The blade ring (2) is inserted, together with the blades (5), in an annular guide (7) of the mount (1) and is coupled with an adjusting ring (8), which is rotatably mounted in the annular guide (7) and which has at its outer circumference control elements (9) for rotating the blade ring (2). A cover mask (10) with a central passage, through which the actuating element (6) for the blades (5) is accessible or from which the actuating element protrudes to be operable, is present in the opening of the adjusting ring (8).
