Vehicle Ventilation Air-Guiding Vanes for Three-Duct Flow Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air-guiding systems for vehicle ventilation can only distribute air flow to two discharge ducts, limiting flexibility and efficiency in air distribution within the vehicle interior.
Innovation Solution
The introduction of an auxiliary guiding vane connected to the main guiding vane at a fixed angle, along with a skillful arrangement of ducts and their opening apertures, allows for the distribution of air flow to three discharge ducts by pivoting the control part, enhancing compactness and flow efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the air-guiding system uses only a main guiding element and a secondary guiding element, then the structure remains simple, but the air flow can be distributed to only two discharge ducts
Solution Approach 1:
The main guiding element is segmented into a main guiding vane and an auxiliary guiding vane that are connected at a fixed angle. This segmentation allows the single control part to manage three discharge ducts instead of two, as the auxiliary vane can independently block or constrict flow paths to adjacent outflow ducts while the main vane controls the primary flow distribution.
2Volume of stationary object
If the control part is arranged with the pivot axis at a distance from the main guiding element, then the guiding elements can be positioned favorably for flow, but the pivoting space requires larger volume
Solution Approach 1:
The pivot axis is merged with the main guiding element by positioning it adjacent to the main guiding vane rather than at a distance. The hub surrounding the pivot axis connects to the main guiding vane in a central region, combining the rotational support function with the guiding structure itself. This integration reduces the pivoting space volume while maintaining the ability to position guiding elements favorably for flow.

Function Achieved in This Case
Enables optimal and variable air flow distribution to three discharge ducts, improving airflow management and reducing the volume required for the control part's pivoting mechanism, while maintaining airflow efficiency and flexibility.
Implementation Method 1
the auxiliary guiding vane blocking off or at least constricting a direct flow path between two adjacent outflow ducts
Implementation Method 2
the main guiding vane together with the secondary guiding vane distributing, as a function of the pivoting position of the control part, an air flow, arriving from the supply duct, between the discharge ducts

AI summary
An air-guiding system for a ventilation system of a vehicle comprises a supply duct (12), three discharge ducts (14, 16, 18) branching off from the latter and a control part (20), which has a main guiding element (24) with a main guiding vane (24a) and also a secondary guiding element, kept at a distance from the latter, with a secondary guiding vane (26) and can be pivoted about a pivot axis (22). The main guiding element (24) is provided with an auxiliary guiding vane (24b) which is connected at one of its ends to the main guiding vane (24a) at a fixed angle and on the opposite side has a free end, the main guiding vane (24a) together with the secondary guiding vane (26) distributing, as a function of the pivoting position of the control part (20), an air flow, arriving from the supply duct (12), between the discharge ducts (14, 16, 18), and the auxiliary guiding vane (24b) blocking off or at least constricting a direct flow path between two adjacent outflow ducts (16, 18). With just one control part (20) the air flow can be distributed from the supply duct (12) to three outflow ducts (14, 16, 18) in a manner favorable for flow and optimally.
