Vehicle Column Air Outlet Layout for Wider, Indirect Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle air outlet structures in low-configuration vehicles result in uneven air distribution between the front and back rows, directly blowing air to passengers, and have a narrow air supply range, reducing user comfort.
Innovation Solution
An air outlet structure with parallel first and second air outlets and inducing channels that intersect and scatter airflow, along with slit-shaped openings and swing blade assemblies, to enhance air distribution and prevent direct airflow to passengers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If air outlet micropores are formed in the column to provide air supply, then the air outlet structure can be implemented, but the air supply range is relatively narrow and air directly blows to the passenger
Solution Approach 1:
The air outlet structure is divided into multiple air outlets (first air outlet and second air outlet) with corresponding air-inducing channels. Each channel guides airflow separately, allowing the air supply function to be segmented into multiple directional streams that can be independently controlled and distributed, thereby expanding the overall air supply range while preventing direct blowing to passengers.
Solution Approach 2:
The air-inducing channels are configured to extend airflow in multiple spatial dimensions rather than a single direction. The first and second air-inducing channels create three-dimensional airflow distribution, guiding air along different paths and angles to expand coverage area and eliminate direct airflow impact on passengers.
2Ease of operation
If air outlet is arranged close to instrument panel, then front row ventilation and defrosting can be achieved, but back row air supply is insufficient resulting in uneven temperature distribution
Solution Approach 1:
The air outlet system is segmented into multiple independent air outlets positioned at different locations and orientations. This segmentation allows airflow to be distributed to different zones (front row and back row) simultaneously, achieving uniform temperature distribution across the entire cabin space.
Solution Approach 2:
The air outlet structure is designed with multi-functionality to serve both front row ventilation/defrosting and back row air supply needs. The first and second air outlets with their respective inducing channels create a universal air distribution system that addresses multiple cabin climate requirements through a single integrated structure.
3Device complexity
If single air outlet configuration is used, then device complexity is reduced, but air supply range and distribution uniformity are limited
Solution Approach 1:
The air outlet structure is divided into multiple air outlets and air-inducing channels, each performing a specific airflow guidance function. This segmentation enables the system to achieve expanded air supply range and improved distribution uniformity while maintaining relatively simple individual component designs that can be manufactured and assembled efficiently.
