Vehicle Air Register Knob Layout for Flattened Vent Passages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing register device for vehicles compromises aesthetic quality due to the operation knob being disposed over a fixed current plate, increasing its vertical dimension and obstructing a horizontally-elongated air passage configuration.
Innovation Solution
A register device with a flattened air passage and a sliding operation knob that fits between parallel flat plate portions, allowing for synchronized rotation and sliding operations of upstream and downstream fins to adjust airflow direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the operation knob is disposed over a fixed current plate, then the operation structure is simplified, but the vertical dimension increases and aesthetic quality deteriorates
Solution Approach 1:
The operation knob is relocated from the vertical dimension (disposed over fixed current plates) to the horizontal dimension (disposed in front of the air passage). This dimensional shift reduces the vertical profile while maintaining operational functionality, thereby improving aesthetic quality without complicating the operation structure.
2Productivity
If the air passage is configured with greater horizontal dimensions, then the airflow capacity is improved, but the vertical dimension increases and aesthetic quality deteriorates
Solution Approach 1:
The air passage geometry is reconfigured to extend horizontally rather than vertically. By orienting the long dimension of the air passage in the horizontal direction (front-to-back) rather than vertically, the patent achieves adequate airflow capacity while maintaining a compact vertical profile that improves aesthetic quality.

AI summary
A register device includes a register body, a plurality of upstream fins, a single downstream fin and an operation knob. The plurality of upstream fins are supported by the register body so as to be rotatable about a rotation axis extending in a left-right direction. The plurality of upstream fins are arranged in a vertical direction. The downstream fin is disposed in an air passage on a blow outlet side with respect to the upstream fins. The downstream fin is supported by the register body so as to be rotatable about a rotation axis extending in the vertical direction. The downstream fin extending in the vertical direction includes a pair of flat plate portions extending in the vertical direction parallel to each other. The operation knob is supported by the downstream fin so as to be slidable in the vertical direction. The operation knob, as it is slid, rotatably operates the upstream fins. The operation knob is disposed between the pair of flat plate portions so as to be fit in a space between the pair of flat plate portions in the left-right direction.
