Front-Wheel Airflow Deflector With Compact Radial Drive Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deflector devices for vehicle front wheels are not compact in the axial direction, which affects their efficiency and integration within the vehicle.
Innovation Solution
A deflector device comprising a deflector body, drive member, and transmission member with projections and coupling portions that allow for compact axial design, enabling deployment and stowage of the deflector body to manage airflow, utilizing a drive member to transmit force through a projection-engaging mechanism.

Engineering Contradiction Analysis
1Length of moving object
If a conventional transmission member design is used, then the drive force can be transmitted, but the axial dimension becomes large
Solution Approach 1:
The transmission member uses a projection that extends in the radial direction rather than the axial direction to engage with the drive member. This dimensional shift allows drive force transmission while reducing the axial dimension of the transmission member, directly resolving the technical contradiction between compact axial size and functional capability.
Solution Approach 2:
The projection of the transmission member is designed to be movable relative to the drive member during engagement and disengagement. This dynamic design allows the projection to be inserted into or removed from the drive member's engagement portion, enabling flexible transmission of drive force while maintaining a compact axial structure.
2Ease of operation
If the projection is made movable, then engagement and disengagement is enabled, but the structural complexity increases
Solution Approach 1:
The transmission member is segmented into a projection portion and a body portion, where the projection can move independently relative to the body. This segmentation enables the projection to be engaged with or disengaged from the drive member while the rest of the transmission member remains stable, simplifying the overall engagement mechanism.
Solution Approach 2:
The projection acts as an intermediary element between the transmission member and the drive member. By making the projection movable rather than moving the entire transmission member, the design simplifies the engagement and disengagement process while maintaining structural integrity.

AI summary
A deflector device includes a deflector body that is configured to be deployed in front of a front wheel of a vehicle by being rotated in a deploy direction and to suppress airflow onto the front wheel, and that is configured to be stowed in a body of the vehicle by being rotated in a stow direction; a drive member that is configured to transmit drive force; and a transmission member that is provided with a projection that protrudes in a radial direction thereof and that is configured to be engaged with the drive member such that drive force from the drive member is transmitted to the transmission member and the deflector body is rotated.
