Dynamic Glare Obscuring Translucent Spots on Vehicle Windshields
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for reducing glare in vehicles are ineffective as they fail to adapt to the movement of the vehicle and the source of glare, limiting a driver's ability to see oncoming traffic, road signs, and brake lights.
Innovation Solution
A system using CCD cameras to track glare and driver/passenger eye positions, with a processor determining the placement of translucent spots on a transparent display to dynamically obscure glare, adjusting for vehicle and eye movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transparent display with translucent spots is used to reduce glare, then visibility is improved, but device complexity increases
Solution Approach 1:
The display surface is segmented into multiple independently controllable translucent spots rather than a uniform opaque display. Each spot can be individually activated and positioned to counter specific glare sources while maintaining transparency in other areas, thus improving visibility without requiring complete obscuration.
Solution Approach 2:
The display provides different optical properties at different locations - translucent spots are created only at specific positions where glare is detected, while the rest of the display remains transparent. This localized approach addresses glare problems without sacrificing overall visibility through the window.
2Adaptability or versatility
If existing static glare reduction solutions are used, then device complexity is low, but adaptability to movement deteriorates
Solution Approach 1:
The system dynamically tracks the movement of glare sources and driver eyes using cameras and processors, continuously updating the position and properties of translucent spots on the display. This dynamic adaptation allows the system to maintain effectiveness as the vehicle moves and glare conditions change.
Solution Approach 2:
The system uses cameras to detect glare sources and eye positions, processes this information to determine optimal spot placement, and adjusts the display accordingly. This closed-loop feedback mechanism enables real-time adaptation to changing glare conditions and driver position.
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
Effectively reduces glare by dynamically tracking and adjusting translucent spots on vehicle windows and mirrors, improving visibility for drivers and passengers by compensating for movement and intensity of glares.
Implementation Method 1
a transparent display to present a translucent spot at the first position

AI summary
Systems and methods for obscuring glares that are present on a windshield, mirror other surface of a vehicle are presented. The systems and methods comprise first and second sets of CCD cameras, where the first set is used to provide information about a source of a glare and the second set is used to provide information about eyes of a driver, for example. Based on the information gathered, locations of the source of the glare and the driver's eyes can be triangulated, and a position where light from the source of the glare is incident on the windshield or other surface can be determined. A translucent spot can be generated at that position to obscure the glare (light) from reaching the driver's eyes.
