Vent Register Vane Assembly for Narrow Airflow Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ordinary slim vent registers tend to blow a wide air plume due to vertically extending vanes having the same angular orientation, leading to air fanning and inefficient airflow directionality.
Innovation Solution
A vent register design featuring vertically extending vanes with different angular orientations, interconnected by a mechanical assembly that includes gear sub-assemblies and linkages, allowing the vanes to move horizontally together while maintaining distinct orientations to direct airflow as a tight stream.

Engineering Contradiction Analysis
1Ease of manufacture
If vertically extending vanes have the same angular orientation, then the structure is simple and easy to manufacture, but the airflow fans out and forms a wide air plume
Solution Approach 1:
The patent applies local quality by giving different angular orientations to different vanes within the same register assembly. Specifically, the first set of vanes has a first angular orientation while the second set of vanes has a second angular orientation that is different from the first. This local differentiation allows each vane to direct airflow in a specific direction, preventing the fan-out effect and creating a more focused air plume while maintaining manufacturing simplicity through the use of standardized vane components.
2Ease of operation
If all vanes are interconnected to rotate together, then the operation is simplified to a single control, but the ability to adjust different airflow directions is reduced
Solution Approach 1:
The patent applies segmentation by dividing the vanes into distinct functional groups - a first set of vanes and a second set of vanes - where each set can be independently adjusted. The mechanical linkage system allows these segments to be controlled separately, enabling the first set to direct airflow in one direction while the second set directs airflow in a different direction. This segmented approach provides both operational simplicity through standardized control mechanisms and adaptability through independent adjustment of each vane set.

AI summary
A vent register includes a set of vanes and a mechanical assembly. Each vane is pivotably affixed to a respective stationary point to be rotatable about the stationary point. The mechanical assembly interconnects the vanes so that all of the vanes rotate together in response to one of the vanes being actuated to rotate. At least one of the vanes has an orientation different than at least another one of the vanes such that the at least one of the vanes and the at least another one of the vanes point in different directions as the vanes are rotated.
