Vector Air Outlet Layout for Hidden Louvers and Compact Air Deflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ventilation air outlets in motor vehicles have the disadvantage of deflecting louvers projecting into the viewing area, which is visible to passengers, and often have large dimensions that conflict with design inputs of vehicle cockpits.
Innovation Solution
A vector air outlet design with a channel partition wall dividing the air channel into subchannels, a pivotable control valve, and deflecting louvers supported eccentrically on the housing, allowing for greater air flow deflection with reduced dimensions and improved louver integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If deflecting louvers are arranged in conventional air outlets to enable air flow diversion, then air flow control is improved, but the louvers project into the viewing area and become visible to passengers
Solution Approach 1:
The patent repositions the pivot axis of the deflecting louvers from a conventional location to the louver foot region, which is closer to the air outlet housing wall. This dimensional repositioning allows the louvers to be effective for air flow diversion while minimizing their projection into the passenger viewing area, thereby resolving the contradiction between operational effectiveness and aesthetic visibility.
2Quantity of substance
If conventional air outlets are designed to discharge predefined air flow, then ventilation function is achieved, but the dimensions are comparatively large and conflict with vehicle cockpit design inputs
Solution Approach 1:
The patent changes the geometric parameters of the air outlet by positioning the pivot axis in the louver foot region and optimizing the louver arrangement. This allows the air outlet to maintain its air flow discharge capacity while reducing the overall installation space required, thereby resolving the contradiction between ventilation performance and compact dimensions.

AI summary
A vector air outlet for a ventilation system for a motor vehicle, including an air outlet housing through which an air channel having a channel inlet and a channel outlet is formed. A horizontally formed channel partition wall divides the air channel into a first subchannel and a second subchannel. A control valve arranged upstream from the channel partition wall in the flow direction, is pivotable around a first pivot axis formed transversely to the flow direction. A plurality of deflecting louvers are arranged in the first subchannel and the second subchannel and are held on the air outlet housing pivotable around a second pivot axis formed transversely to the first pivot axis in the flow direction. The deflecting louvers have a longitudinal extension in the flow direction from a louver head region via a louver intermediate region to a louver foot region.
