Vehicle Air Register Shutter Layout for Accurate Airflow Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air registers in vehicles have numerous moving parts, leading to inaccurate airflow direction and increased risk of part failure, while redirected air affects the cumulative flow angle, resulting in inefficiencies and higher manufacturing costs.
Innovation Solution
An air register design featuring a housing with vertical blades and a slidable shutter that controls airflow by translating laterally, reducing the need for multiple moving components and enhancing airflow accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple vertical vanes are used to direct airflow in multiple directions, then airflow directionality is improved, but device complexity increases due to numerous moving components
Solution Approach 1:
The air register is divided into two functional segments: fixed vertical blades that provide airflow directionality and a slidable shutter that controls flow volume. This segmentation eliminates the need for multiple moving vane components while maintaining directional control capabilities through the fixed blade geometry combined with shutter positioning.
Solution Approach 2:
Instead of using multiple movable vanes to control airflow direction, the invention inverts the approach by using fixed blades with a single slidable shutter. The shutter's lateral translation controls which fixed blades are active, thereby controlling airflow direction indirectly through selective activation rather than direct mechanical rotation of multiple components.
2Loss of energy
If air contacts side walls and is redirected, then some airflow is lost, but manufacturing simplicity is improved by not requiring complex sealing mechanisms
Solution Approach 1:
The slidable shutter acts as an intermediary element between the air source and the fixed blades. By laterally translating the shutter, airflow is selectively directed through specific gaps to engage predetermined fixed blades, thereby controlling cumulative flow angles without requiring complex sealing mechanisms to prevent side wall contact.
3Device complexity
If a slidable shutter is used to control airflow, then device complexity is reduced, but manufacturing precision requirements increase for the shutter mechanism
Solution Approach 1:
The slidable shutter mechanism is designed to be manually operable without requiring complex actuation systems. The shutter's lateral translation is directly coupled to the selection of active fixed blades, allowing the mechanism to self-regulate airflow direction and volume through simple user input, thereby reducing overall device complexity while maintaining adequate precision through mechanical directness rather than complex control systems.

AI summary
An air register including a housing defining a rear opening and a front opening, a blade member provided within the housing and including a plurality of vertical blades, and a shutter located between the blade member and the front opening of the housing, the shutter being slidably movable relative to the housing. Translation of the shutter in a vehicle lateral direction controls a flow of air through the plurality of vertical blades. The blade member includes a plurality of vertical blades. Movement of the shutter in a first direction positions the shutter to overlap one or more of the plurality of vertical blades, and movement of the shutter in a second direction opposite the first direction positions the shutter to overlap a different one or more of the plurality of vertical blades.
