Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for mitigating visual dizziness caused by direct sunlight, such as wearing sunglasses, often result in a darkened exterior scene and poor vision in low-light conditions.
Innovation Solution
A light shielding plate assembly comprising a transparent panel with adjustable light transmittance, an image collecting module, a detection module, and a control module that determines the gaze point of the human eye and adjusts the light transmittance in specific areas to maintain optimal optical information within a preset range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If sunglasses are worn to block direct sunlight, then visual dizziness is reduced, but the exterior scene becomes darkened and vision deteriorates in low-light conditions
Solution Approach 1:
The transparent panel is divided into multiple independently controllable control areas, allowing different regions to have different light transmittance properties. The area where direct sunlight causes dizziness can be locally darkened while other areas maintain high transparency, preserving overall scene brightness and visibility.
Solution Approach 2:
The panel is segmented into multiple control areas that can be independently adjusted. This segmentation allows selective application of light blocking only in specific regions experiencing harmful direct sunlight, rather than uniformly darkening the entire panel, thus maintaining exterior scene visibility.
2Object-affected harmful factors
If a transparent panel with adjustable light transmittance is used, then visual dizziness is reduced while maintaining clear exterior view, but the system complexity increases due to multiple control modules
Solution Approach 1:
The system incorporates detection modules that automatically sense direct sunlight conditions and trigger appropriate light transmittance adjustments without requiring manual user input. The control module autonomously manages the multiple control areas, reducing the perceived complexity for users while maintaining sophisticated functionality.
Solution Approach 2:
Detection modules continuously monitor lighting conditions and provide feedback to the control module, which adjusts the light transmittance of control areas accordingly. This closed-loop feedback system automates the complexity management, allowing the system to adapt dynamically to changing sunlight conditions without requiring complex manual controls.
