Vehicle Air Diffuser With Hidden Partition Airflow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air vents for vehicles often impede the design of the passenger compartment due to their visible fin structures and fixed airflow directions, limiting design flexibility and aesthetics.
Innovation Solution
An air vent design featuring a movable partition within a chamber that allows airflow to be directed through multiple outlets with adjustable positions, enabling controlled airflow direction without altering the vent's external appearance, using a plastics housing and an electric drive mechanism for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fin structure is integrated into the air outlet to enable airflow direction control, then the airflow direction can be adjusted, but the air outlet size increases and the design of the vehicle passenger compartment is impeded
Solution Approach 1:
The air vent is divided into multiple independent outlets (first air outlet and second air outlet), each capable of being independently controlled by the partition. This segmentation allows the air outlet area to remain small while still providing comprehensive airflow direction control through selective activation of different outlets.
Solution Approach 2:
The partition is made movable between different positions to dynamically control which air outlets are active. This dynamic mechanism allows the same physical structure to provide different airflow patterns without requiring larger outlet areas, as the partition can redirect airflow between multiple smaller outlets.
2Adaptability or versatility
If visible fin structures are used in the air vent to control airflow direction, then airflow can be directed, but the aesthetic design of the vehicle passenger compartment is compromised
Solution Approach 1:
The partition is positioned within the chamber such that it is not visible from the exterior of the air vent. The external appearance maintains clean, simple outlet shapes without visible internal control structures. This extraction of the control mechanism from the visible exterior resolves the contradiction between functionality and aesthetics.
Solution Approach 2:
The chamber acts as an intermediary space that houses the partition and airflow control mechanisms while presenting a clean, aesthetic exterior. The chamber allows the partition to perform its airflow directing function internally without exposing the mechanical structures to the vehicle passenger compartment interior.
3Adaptability or versatility
If multiple air outlets are provided to increase airflow direction flexibility, then airflow can be directed to different regions, but the device complexity increases
Solution Approach 1:
The single partition performs multiple functions by moving to different positions: it can block the first outlet while opening the second, block the second while opening the first, or position itself to allow both to operate. This multi-functionality of a single component provides complex airflow control without requiring multiple independent control mechanisms, thus managing device complexity.

AI summary
An air vent with a feed channel via which air can be fed, including a chamber to which the air can be supplied via the feed channel, and at least one air outlet via which the air can flow into the vehicle compartment. At least one movable partition is provided in the chamber, which partition can be moved into different positions by an adjustment device, in such a way that the airflow can be fed to at least one air outlet.
