Vehicle Sun Visor Module with A-Pillar Air Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sun visor modules in vehicles are ineffective in blocking heat and light transmitted through the wind shield, leading to low cooling efficiency, and are typically only functional when the vehicle is parked.
Innovation Solution
A sun visor module with a sliding sun visor portion, a screen-shaped awning portion, and an air discharge system connected to the A-pillar, which introduces air-conditioner wind to enhance cooling efficiency and block light and heat, while allowing for improved driver visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a general sun visor module is used to block light, then light blocking is achieved, but heat blocking and cooling efficiency are insufficient
Solution Approach 1:
The patent combines multiple functions into a single integrated module: the sun visor module integrates light blocking, heat blocking, and air conditioning wind discharge functions. The base portion houses both the sun visor portion for light blocking and the air discharge portion for releasing cold air, merging previously separate functions into one unified system that simultaneously addresses both light and heat issues.
Solution Approach 2:
The sun visor module is designed as a multi-functional device that performs multiple roles: it blocks light through the sun visor portion, blocks heat through the integrated structure and air discharge mechanism, and provides cooling by discharging air conditioner wind. This universal design allows a single module to replace multiple separate components.
2Object-affected harmful factors
If a multi-functional sun visor with screen is used, then light blocking is improved, but the device is only functional when parking
Solution Approach 1:
The patent employs dynamic elements including the slidable sun visor portion that can move forward and backward to adjust blocking position, and the deployable screen-shaped awning portion that can be extended or retracted. These dynamic features allow the module to adapt to different driving conditions and maintain functionality whether the vehicle is parked or traveling.
Solution Approach 2:
The air discharge portion utilizes pneumatic principles by channeling air conditioner wind through the base portion to create a cooling effect. This pneumatic feature enables the module to function actively during traveling by using the vehicle's air conditioning system to discharge cold air, rather than being static like traditional visors.
3Object-affected harmful factors
If the sun visor portion is made large to block more light, then light blocking improves, but driver view is obstructed
Solution Approach 1:
The patent segments the light blocking function into two parts: the sun visor portion for direct light blocking and the screen-shaped awning portion for additional blocking. This segmentation allows the driver to use only the necessary portion based on lighting conditions, maintaining a clear view when full blocking is not needed while providing extended blocking capability when required.
Solution Approach 2:
The slidable design of the sun visor portion allows it to be positioned dynamically - it can be extended forward to block light when needed and retracted to provide a clear view when not needed. This dynamic positioning resolves the contradiction between blocking area and driver visibility.

AI summary
A sun visor module includes: a base portion which has an accommodating space formed therein and a front portion provided at the ceiling of a front seat of a vehicle in an openable or closable form; a sun visor portion which is provided at the center of the inside of the base portion and slides in or out through the front portion of the base portion; a screen-shaped awning portion which is provided at a lower portion of the inside of the base portion to be entered in or out to the front portion of the base portion; an air discharge portion which is connected with an A-pillar of the vehicle to introduce the wind flowing in the A-pillar into the base portion; and a first blowing portion which communicates with the rear lower portion of the base portion to send the wind to the inside of the vehicle.
