Headliner Air Vent with Hidden Pop-Up Dispersed Outlet Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle air vents, including those in the dashboard and headliner, have limited blowing range and require separate knobs for outlet operations, leading to low productivity and frequent malfunctions, and do not effectively disperse air for user comfort.
Innovation Solution
A headliner air vent device with a rotatable air guide supporter and air guide that convert rotation into linear movement to control outlet states, eliminating the need for external knobs and increasing the dispersed blowing area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate knob members are provided adjacent to dispersed blowing outlets for independent opening/closing operations, then the outlets can be controlled independently, but the device complexity increases and productivity decreases
Solution Approach 1:
The patent merges multiple separate control functions into a single integrated rotator mechanism. The rotator simultaneously controls the main blowing outlet and multiple dispersed blowing outlets through a unified structure, eliminating the need for separate knob members for each outlet while maintaining independent control capability.
Solution Approach 2:
The rotator is designed as a universal control mechanism that performs multiple functions: it controls the main blowing outlet and simultaneously controls multiple dispersed blowing outlets. This multi-functional design reduces the number of components while maintaining comprehensive outlet control.
2Ease of operation
If separate knob members are provided for each dispersed blowing outlet, then each outlet can be controlled independently, but product malfunctioning frequency increases
Solution Approach 1:
By combining multiple separate control mechanisms into a single rotator, the patent reduces the number of potential failure points. The integrated structure eliminates frequent malfunctions associated with multiple separate knobs while maintaining the ability to independently control each outlet group.
3Ease of operation
If a separate intermediate cover member is provided for knob member installation, then knob members can be mounted, but productivity decreases
Solution Approach 1:
The patent extracts and eliminates the unnecessary intermediate cover member from the structure. The rotator is directly integrated into the housing without requiring a separate mounting cover, simplifying the assembly process and improving productivity while maintaining the functional capability of controlling all outlets.
4Force
If air is blown directly through a central blowing outlet, then the blowing force is strong, but the blowing range is narrow and user comfort decreases
Solution Approach 1:
The patent segments the single central blowing outlet into multiple dispersed blowing outlets arranged in different directions. This segmentation allows air to be distributed across a wider range while maintaining blowing force, improving user comfort by providing both direct and indirect blowing options.
Solution Approach 2:
The patent adds spatial dimensionality to the blowing outlets by arranging them in different directions and positions around the central outlet. This dimensional expansion enables air to reach multiple areas simultaneously, widening the effective blowing range while preserving the central outlet's strong blowing force.

AI summary
Proposed is a headliner air vent device for a vehicle. A housing includes a first outlet through which air is discharged and a second outlet comparted by an inner cover and having a configuration by which air is discharged through outside the first outlet. An air guide supporter is rotatable inside the housing. An air guide is positioned to face an outer cover by which the second outlet is defined. The air guide is configured to move upwards or downwards in response to rotation of the air guide supporter to selectively open or close the second outlet.
