Vehicle Air Outlet with Rotational Diffuser for Uniform Temperature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air outlets for vehicle passenger compartments require frequent manual adjustments due to localized air-conditioning, leading to discomfort and uneven temperature distribution, and often produce non-diffuse, directed air flows with high noise levels.
Innovation Solution
An air outlet with a direction and diffuser arrangement that can be moved rotationally and translationally about a center axis, allowing for adjustable flow speed, volume, direction, and diffusivity, featuring a conical front portion and ball joint support for enhanced air distribution and reduced noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment mechanisms are used to control air flow direction, then air discharge direction can be adjusted, but frequent adjustments are required leading to operational inconvenience
Solution Approach 1:
The air outlet system performs self-adjustment by detecting temperature differences between body regions and automatically modifying air flow distribution accordingly, eliminating the need for manual intervention and frequent adjustments by the user
Solution Approach 2:
The system incorporates temperature sensors that continuously monitor body region temperatures and feed this information back to the control unit, which then adjusts the air flow distribution in real-time to maintain thermal comfort without user intervention
2Temperature
If directed air flow is used for localized air-conditioning, then specific body regions can be targeted, but uniform temperature distribution is not achieved
Solution Approach 1:
The system applies different air flow characteristics to different spatial zones by directing air flows toward specific body regions detected by temperature sensors, with each region receiving customized air flow parameters based on its thermal state
Solution Approach 2:
The air flow distribution is dynamically adjusted in real-time based on detected temperature variations, with the system continuously modifying flow directions and intensities to achieve and maintain uniform temperature distribution across different body regions
3Power
If high volume flow is used for air-conditioning, then cooling or heating effect is enhanced, but noise level increases
Solution Approach 1:
The system dynamically changes air flow parameters including velocity, direction, and distribution pattern to achieve the required thermal effect at lower overall volume flows, thereby reducing noise generation while maintaining effective air-conditioning performance

AI summary
An air outlet for controlling an air flow has a ventilator housing and a direction and diffuser arrangement received in the ventilator housing. An air channel is formed by the ventilator housing and the direction and diffuser arrangement. In order to adjust flow properties of the air flow, the direction and diffuser arrangement is constructed so as to be able to be moved in a rotational manner about a center axis of the ventilator housing and/or moved in translation along the center axis of the ventilator housing and/or pivoted relative to the center axis of the ventilator housing.
