Vehicle Dimming Module for Real-Time Windshield Glare Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for reducing glare from the sun or oncoming headlights in vehicles require drivers to manually adjust their visors or turn their heads, leading to potential safety issues due to delayed responses.
Innovation Solution
A vehicle dimming module comprising a first camera element to capture the driver's appearance, a first dimming element to produce adjustable patterns, and a control element to generate initial and change state signals based on the driver's image, adjusting the dimming patterns in real-time to optimize driving vision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the driver manually adjusts the visor or turns his head to avoid glare, then the driver can reduce the impact of sunlight or oncoming headlights, but the driver's response time is delayed and driving safety is compromised
Solution Approach 1:
The system performs preliminary detection of glare sources and driver eye position, then pre-adjusts the dimming element to the appropriate position before the driver needs to take action, eliminating the delayed manual response
Solution Approach 2:
The system uses the driver's own eye position and glare source information to automatically control the dimming element, making the system self-regulating without requiring manual driver intervention
2Object-affected harmful factors
If the driver turns his head to dodge glare, then the driver can avoid the light source, but the driver cannot focus on the road conditions in front of the car
Solution Approach 1:
The system segments the windshield into multiple controllable dimming regions, allowing selective dimming of only the glare-affected area while maintaining clear visibility of the road ahead
Solution Approach 2:
The dimming element acts as an intermediary between the driver and the glare source, blocking harmful light while maintaining the driver's forward-facing position and road focus
3Illumination intensity
If a traditional visor is used to block glare, then the driver can reduce light exposure, but the adjustment requires manual intervention and cannot respond instantly to changing light conditions
Solution Approach 1:
The dimming element's position and dimming level are dynamically adjusted in real-time based on detected glare source position and intensity, allowing instant response to changing light conditions
Solution Approach 2:
The system continuously detects glare sources and driver eye position, providing feedback to automatically adjust the dimming element, creating a closed-loop control system that responds instantly to environmental changes

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 module instantly adjusts the windshield brightness without the need for manual adjustments, enhancing driving safety by maintaining the driver's focus on the road and improving the optical effect of the driving vision.
Implementation Method 1
The control element controls the first dimming element to adjust the grayscale value and/or the transmittance of the first pattern

AI summary
A vehicle dimming module including a first camera element, a first dimming element and a control element is provided. The first camera element is adapted to capture an appearance image of a user. The first dimming element is adapted to generate a first pattern. The control element is electrically connected to the first camera element and the first dimming element. The control element provides initial state signals and changing state signals based on the appearance image. The control element determines a viewing area on the first dimming element based on the initial state signal and drives the first dimming element to generate the first pattern in the viewing area, and the control element controls the first dimming element according to the change state signal to adjust the grayscale value and/or the transmittance of the first pattern.
