Smart Glass Vehicle Compartment for Automatic Sun Glare Shading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle compartment systems for mitigating sun blinding are complex and often inefficient, requiring manual operation or complex sensor systems that may not effectively predict and prevent glare before it affects the occupant.
Innovation Solution
A vehicle compartment with a light sensor located below the expected eye position range, coupled with a panel assembly that adjusts light intensity using electrochromic glass or similar technology, automatically shades the occupant by detecting changes in sunlight exposure and activating panels before glare occurs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a manually operated sun visor is provided, then the occupant can shield from sunlight, but the system requires manual effort and distraction from the occupant
Solution Approach 1:
The system uses a light sensor to automatically detect sunlight intensity and control panels to adjust light transmission, enabling the system to serve itself without requiring manual operation by the occupant
Solution Approach 2:
The patent replaces manual mechanical operation with an automated optical sensing and control system that uses light sensors and electrically controllable panels to adjust light transmission automatically
2Measurement precision
If existing automated systems with multiple sensors are used, then light detection capability is improved, but the system complexity increases
Solution Approach 1:
The patent extracts and uses only the essential light sensing function from complex multi-sensor systems, achieving effective glare detection with a simplified single-sensor approach positioned at the rearview mirror
Solution Approach 2:
The light sensor serves multiple functions: detecting glare conditions, triggering panel activation, and controlling light transmission adjustment, replacing the need for multiple specialized sensors
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
This solution provides a simple, efficient, and reliable means to mitigate sun blinding by sensing incoming light early and adjusting light intensity through the vehicle compartment's panels, ensuring the occupant remains shaded effectively without distracting manual intervention.
