Two-Layer Polarized Visor with Segmented Panels for Glare Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional visors for vehicles often obstruct the driver's or passenger's view of the road when positioned to block glare, as they typically consist of a single pivoting panel that can only be oriented in a way that either blocks glare or allows visibility but not both simultaneously.
Innovation Solution
A visor assembly with adjacent hinged panels made of polarizing material, allowing for translation between open and closed configurations, and an articulating mirror assembly that can be independently positioned to reduce glare without obstructing the view, using magnetic closures and pivotally connected arms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a single panel visor is pivoted to block glare, then glare blocking is improved, but the driver's view of the road is obstructed
Solution Approach 1:
The visor body is divided into two separate panels (first panel and second panel) that can be independently positioned. This segmentation allows each panel to be adjusted separately, enabling one panel to block glare while the other maintains visibility of the road, thus resolving the contradiction between glare blocking and road view.
2Illumination intensity
If a single panel visor is used to block glare, then glare reduction is achieved, but visibility through the windshield is reduced
Solution Approach 1:
The visor is segmented into two panels that can be independently positioned. The first panel can be placed in a first position to block glare, while the second panel can be placed in a second position to maintain visibility through the windshield, thus achieving both glare reduction and visibility.
Solution Approach 2:
The visor panels are designed to be dynamically adjustable to different positions. Each panel can be independently positioned to optimize the balance between glare blocking and visibility based on driving conditions, allowing the system to adapt rather than being fixed in a single configuration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The visor assembly effectively blocks glare from various sources while maintaining an unobstructed view of the road, allowing users to adjust transparency based on glare conditions and enabling independent movement of the mirror assembly for enhanced visibility.
Implementation Method 1
Each of the adjacent panels is fabricated of a polarizing material
Implementation Method 2
The adjacent panels are held in the closed configuration by at least one closure, which in embodiments may be a magnetic closure such as a magnetic bumpstop

AI summary
A visor assembly for a vehicle includes a visor body comprising adjacent hingedly connected panels each fabricated of a polarizing material. A closure is provided to hold the adjacent panels in a closed configuration. The assembly may further include an articulating mirror assembly whose movement is independent of any movement of the visor assembly.
