Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle visors are limited in size and range of motion, often insufficient to completely block glare from the sun or other light sources, leading to partial or complete visual impairment for drivers and passengers.
Innovation Solution
A light glare reducing apparatus comprising a first polarized body and a second polarized body with a movable coupling, allowing adjustable variance in the angle of polarization to effectively filter out glare by overlapping and rotating the polarized materials, which can be attached to a vehicle visor for enhanced glare reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional vehicle visors are used to block glare, then some light blocking is achieved, but the visors are limited in size and range of motion, resulting in insufficient glare reduction
Solution Approach 1:
The apparatus divides the glare reduction function into two separate polarized bodies (first and second polarized bodies) that can independently rotate and overlap at different angles. This segmentation allows each component to be optimized for specific glare directions while maintaining overall adaptability across multiple angles and positions.
Solution Approach 2:
The invention introduces rotational mechanisms that allow both polarized bodies to dynamically adjust their orientations independently. This dynamic capability enables the apparatus to adapt to varying glare sources and positions, overcoming the static limitations of conventional visors and providing continuous adjustment for optimal glare reduction.
2Object-affected harmful factors
If polarized lenses are used to filter light, then glare is reduced, but the polarization angle is fixed and cannot be adjusted for different glare sources
Solution Approach 1:
Both polarized bodies are equipped with rotational mechanisms that enable dynamic adjustment of their polarization angles. This allows the apparatus to adapt to different glare sources and positions by rotating the polarized bodies to optimal orientations, overcoming the fixed angle limitation of conventional polarized lenses.
Solution Approach 2:
The apparatus combines two different polarized materials with potentially different polarization characteristics into a single system. This composite approach allows for more versatile glare reduction by utilizing the complementary properties of both materials and their ability to be independently oriented at different angles.

Function Achieved in This Case
The apparatus provides adjustable and effective glare reduction by varying the angle of polarization, minimizing light interference and improving visibility in vehicles by filtering out glare from different angles and locations.
Implementation Method 1
Optically polarized materials are widely used to filter light such that a portion of light that is polarized in the same direction as the polarization of the polarized materials is filtered out

AI summary
Disclosed are light glare reducing apparatuses and related methods. A light glare reducing apparatus includes a first polarized body, a second polarized body, and a movable coupling that attaches the second polarized body to the first polarized body with the second polarized body at least partially overlapping the first polarized body. The first polarized body includes a first polarized material that is optically polarized in a first direction relative to the first polarized body. The second polarized body includes a second polarized material that is optically polarized in a second direction relative to the second polarized body. The movable coupling is configured to enable the second polarized body to move relative to the first polarized body to change an angle of the second direction relative to the first direction.
