Wind direction adjustment device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wind direction adjustment device for vehicles is cumbersome in operation, particularly when switching from the dispersive air-blowing mode to the inclined air-blowing mode, as the operation knob cannot move laterally, leading to reduced usability and potential abandonment of the inclined air-blowing mode due to complexity in knob operations.
Innovation Solution
The device allows the operation knob to move laterally in the dispersive air-blowing mode by restricting its movement to a horizontal direction relative to the slider, enabling smooth transitions between parallel, dispersive, inclined, and deformation dispersive air-blowing modes through a link mechanism that adjusts fin positions, enhancing operational simplicity and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the operation knob is supported movably to front and back relative to the horizontal-type fin, then the support structure of the knob is simplified, but the knob cannot move to the right and left in the dispersive air-blowing mode, complicating the switching operation
Solution Approach 1:
The operation knob is designed to move not only in the front-back direction but also in the right-left direction by integrating it with the horizontal-type fin's lateral movement capability. This dimensional extension allows the knob to access additional operational positions without complicating its support structure, resolving the contradiction between structural simplicity and operational ease
2Adaptability or versatility
If the knob operation requires pushing to switch from dispersive to parallel air-blowing mode before moving right and left, then the switching sequence is controlled, but the operator may abandon the inclined air-blowing mode due to operational complexity
Solution Approach 1:
The invention merges the functions of mode selection and directional control into a single integrated knob operation. By allowing the knob to move laterally alongside the horizontal-type fin, the system combines what were previously separate operations into one unified control mechanism, enabling operators to access all air-blowing modes including the inclined mode without complex multi-step sequences

AI summary
A wind direction adjustment device includes a plurality of fins supported at top and bottom end sides in a case; a link mechanism associating the fins; a horizontal-fin supported at right and left end sides at second support portions in the case; and a knob supported movably to front and back and to right and left relative to the horizontal fin. The wind direction adjustment device adjustably switches between a parallel air-blowing mode wherein the fins become approximately parallel to one another and a dispersive air-blowing mode wherein two or more of the fins are turned in opposite directions through the knob. The parallel air-blowing mode is switched to the dispersive air-blowing mode by operating the knob forward or backward in an air-blowing direction, wherein by operating the knob to a right or left side, some fins turn in an approximately same direction to switch a dispersive air-blowing direction.
