Adjustable Vehicle Display Mounting for Glare Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Displays mounted separate from a vehicle instrument panel are prone to glare from direct sunlight, particularly in vehicles with convertible tops, which reduces visibility for the driver.
Innovation Solution
An adjustable display system that uses a movable mount and a controller to adjust the display's position based on the sun's position, vehicle location, and occupant's position, rotating the display about a horizontal axis to eliminate reflections and modify the visual appearance of information to maintain readability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display is mounted separate from the instrument panel to improve visibility and aesthetics, then the display can be positioned for better viewing angles and design flexibility, but the display becomes exposed to direct sunlight causing glare and reducing readability
Solution Approach 1:
The display mount is made dynamically adjustable rather than fixed, allowing the display to be repositioned based on sun position and driver location. The motorized actuator enables the display to change its angular position automatically, transforming a static mounting solution into a dynamic one that adapts to varying environmental conditions and eliminates glare while maintaining optimal viewing angles.
2Device complexity
If a fixed mount is used to simplify the structure, then the device complexity is reduced, but the display cannot adapt to changing sun positions and driver locations throughout the day
Solution Approach 1:
The system employs sensors to detect the position of the sun and the driver, then automatically calculates and executes the optimal display angle without requiring manual intervention. The controller processes sensor data and commands the actuator to adjust the display position autonomously, enabling the system to self-adapt to changing conditions throughout the day while maintaining structural simplicity through automated control.
3Adaptability or versatility
If the display position is adjusted manually to reduce glare, then adaptability to sun position is improved, but the ease of operation decreases and requires continuous driver intervention
Solution Approach 1:
The system incorporates sensors that continuously monitor the position of the sun and the driver, providing real-time feedback to the controller. Based on this feedback, the controller automatically adjusts the display position to optimal angles that eliminate glare while maintaining clear visibility for the driver. This closed-loop feedback mechanism eliminates the need for continuous manual adjustment while preserving adaptability to changing conditions.

AI summary
A disclosed adjustable display assembly includes a display viewable by a vehicle occupant, a mount supporting the display relative to the vehicle occupant. The mount is movable to adjust a position of the display relative to the vehicle occupant. A controller receives information utilized to determine an orientation of the display that would result in a reflection effecting viewing of the display by the vehicle occupant and commanding movement of the mount to eliminate reflections on the display viewable by the vehicle occupant.
