Night-Driving Glasses With Segmented Tinted Lens Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face challenges with visibility due to bright oncoming headlights and fog lights, which can cause temporary blindness and reduce visibility, especially in inclement weather, leading to increased risk of accidents.
Innovation Solution
A night-driving glasses device with varying tinted lens areas that attenuate bright lights while preserving clear views of road safety features, featuring a frame with a hinge for compact storage and nose pads for comfort, allowing users to switch between tinted and clear areas to manage glare and visibility needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a dark tint is applied to the entire lens to block oncoming bright lights, then glare reduction is improved, but visibility of road safety features deteriorates
Solution Approach 1:
The lens is divided into multiple distinct zones with different tint densities. The upper portion contains darker tinted areas for blocking oncoming headlights, while the lower portion has lighter or clear areas for viewing road safety features. This segmentation allows each zone to perform its specific function optimally without compromising the other.
Solution Approach 2:
Different regions of the lens are assigned different optical properties (tint densities) according to their specific functional requirements. The upper lens area has darker tint for glare reduction, while the lower lens area has lighter tint for clear viewing of road features. This local differentiation of properties resolves the contradiction between glare blocking and visibility.
2Illumination intensity
If a varying tint gradient is applied to the lens, then both glare reduction and visibility are improved, but manufacturing complexity increases
Solution Approach 1:
Instead of creating a complex continuous gradient, the lens is segmented into discrete zones with specific tint densities. This approach achieves the dual benefit of glare reduction and visibility while simplifying manufacturing, as discrete tinted zones can be more easily produced than precise continuous gradients.
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
Enhances user visibility while driving by reducing glare from oncoming lights and maintaining clear views of road features, thereby reducing the risk of accidents and improving safety during nighttime driving.
Implementation Method 1
The lens is comprised of at least one lens area, wherein, each lens area has a varying degree of tint. This provides a user with an area to block oncoming bright lights and an area for clearly viewing safety features on a road.
Implementation Method 2
applying varying degrees of tints to the lenses. Furthermore, the night-driving glasses device provides a user with multiple lens areas to attenuate bright lights while preserving clear viewing of oncoming signs, lines, and other road safety features.

AI summary
A night-driving glasses device is provided. The device is comprised of at least one frame with at least one lens. The lens may be comprised of a first area, a second area, and a third area. The lens areas have varying degrees of tint to optimally reduce bright lights or promote clear viewing while driving and using the device. Each tint gradually or sharply attenuates into the next tint to provide a smooth viewing transition.
