Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Slim type air vents for automotive vehicles face challenges in adjusting air flow direction due to their compact design, which limits design freedom and ease of air flow direction adjustment compared to conventional vents.
Innovation Solution
An apparatus with a nozzle type wing that can rotate angularly upwards or downwards is mounted inside the slim air vent, equipped with gears on a single transverse wing for easy angular and rotational operation, allowing upward or downward adjustment of air flow direction through a system of driving and driven gears.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple transverse wings and vertical wings are employed in a conventional air vent, then the direction of air flow can be easily adjusted to direct toward the occupant's body, but the size of the air vent becomes large causing packaging problems and occupying large installation space
Solution Approach 1:
The patent divides the air vent into multiple functional components: a damper assembly with multiple transverse wings for flow direction control, and separate vertical wings for flow distribution. This segmentation allows each component to perform its specific function efficiently while maintaining a compact overall structure that reduces installation space requirements.
Solution Approach 2:
The patent implements a nested structure where the damper assembly with multiple transverse wings is integrated within the air vent housing, and vertical wings are positioned within the airflow path. This nesting arrangement allows multiple functional elements to coexist in a compact configuration, reducing the overall installation footprint while maintaining full directional adjustment capability.
2Area of stationary object
If a slim type air vent with a single transverse wing is used, then the installation space is reduced and design freedom is enhanced, but the direction of air flow cannot be easily adjusted to direct upwards or downwards
Solution Approach 1:
The patent merges the functions of multiple transverse wings into a single integrated damper assembly that can rotate to different positions. This single damper assembly with rotational capability combines the directional control functions of multiple separate wings, maintaining full upward and downward air flow adjustment while occupying minimal installation space characteristic of slim type vents.
Solution Approach 2:
The patent employs a dynamic damper assembly that can rotate angularly to different positions rather than using fixed separate wings. This dynamic component can be adjusted to various angles to direct air flow upwards, downwards, or horizontally, providing the same functional capability as multiple fixed wings but in a compact slim structure that enhances design freedom.
3Shape
If the horizontal length of the air duct is increased and vertical height is reduced to create a slim type air vent, then design freedom of peripheral components is enhanced, but the structure becomes more constrained for mounting adjustment mechanisms
Solution Approach 1:
The patent resolves the spatial constraint of the slim horizontal duct structure by moving the adjustment mechanism into the vertical dimension. The damper assembly rotates about a horizontal axis, allowing angular adjustment in the vertical plane without requiring additional horizontal space. This dimensional transformation enables full directional control while maintaining the compact horizontal footprint required for slim type air vents.

Function Achieved in This Case
Enables easy adjustment of air flow direction into the cabin, enhances design freedom by maintaining a slim appearance while ensuring air flow straightness and ease of operation.
Implementation Method 1
gears for rotating the nozzle type wing upwards or downwards are formed on a single transverse wing exposed to the outside, wherein a manipulation force for rotating the single transverse wing angularly upwards or downwards can be transmitted to the nozzle type wing through the gears

AI summary
An apparatus for adjusting direction of air flow of a slim type air vent for an automotive vehicle may include a nozzle type wing that can rotate angularly upwards or downwards and be mounted inside the air vent having slim structure and a gear for rotating the nozzle type wing upwards or downwards is formed on a single transverse wing exposed to the outside such that manipulation force for rotating the single transverse wing angularly upwards or downwards can be transmitted to the nozzle type wing through the gear to rotate the nozzle type wing angularly upwards or downwards and hence the upward or downward direction of air flow being discharged into a cabin can be easily adjusted by upward or downward angular and rotational operation of the nozzle type wing.
