Windshield Display Integration for Interactive Vehicle Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automotive laminated glass displays lack interactivity, real-time communication with vehicle systems, and fail to provide seamless integration with remote control devices for displaying alerts and notifications on the windshield.
Innovation Solution
An interactive system is integrated into the windshield using a display unit composed of illumination devices between substrates, communicating with vehicle sensors and the engine control unit to display real-time status, receive user inputs, and activate alerts via a processing unit that controls the display based on sensor, user, and remote control device data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If electroluminescent devices are integrated into laminated glass for lighting and aesthetic purposes, then illumination functionality is improved, but interactivity and real-time communication capabilities deteriorate
Solution Approach 1:
The electroluminescent device is designed to perform multiple functions: it provides illumination for aesthetic purposes while simultaneously serving as a display medium for interactive notifications and alerts. The device receives control signals from the vehicle's control system to dynamically change its illumination patterns, colors, and intensity based on real-time vehicle status, thereby achieving both lighting functionality and interactivity through a single integrated component.
2Loss of information
If display devices are added to the windshield for real-time status display, then information communication is improved, but device complexity deteriorates
Solution Approach 1:
The patent combines the display functionality with the existing windshield structure by integrating electroluminescent devices directly into the laminated glass. This merging approach eliminates the need for separate display units and reduces system complexity by utilizing the windshield as both a structural component and an information display medium, thereby improving information communication without proportionally increasing device complexity.
3Illumination intensity
If the electroluminescent device is integrated into the laminated glazing, then aesthetic purpose is improved, but safety and electrical insulation in case of damages deteriorate
Solution Approach 1:
The electroluminescent device is nested within the multi-layered laminated glass structure, which provides inherent protection. The device is positioned between the glass layers and surrounded by interlayer materials that provide electrical insulation and mechanical protection. This nested configuration ensures that even if the outer glass is damaged, the electroluminescent device remains protected and electrically isolated, maintaining safety while preserving aesthetic lighting functionality.
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
Enables real-time display of vehicle status and user-configured alerts on the windshield, providing seamless communication with vehicle systems and remote control devices, enhancing safety and user interaction.
Implementation Method 1
Automotive glazings are particularly designed to provide the driver a view of the forward region of the vehicle during driving and rearward region of the vehicle during reversing and other maneuvers. More recently, automobile laminated glass has shown a trend to incorporate functional elements such as LED and EL into the laminated glass for lighting units, indicator lights etc.
