AR Windshield Display Lens System for Unobstructed Driving Info
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices, navigation devices, and head-up displays fail to integrate vehicle network information, affecting driving safety by either obstructing the field of view or being difficult to recognize due to brightness issues, and lack integration of vehicle network status.
Innovation Solution
An augmented reality display system comprising an input unit, operation processing unit, and output unit that processes environment information to determine display sequence, size, brightness, and color based on importance weights, using a transparent display with a sequence of lenses to project information directly into the user's eyes, allowing simultaneous viewing of background and display images while transmitting vehicle network information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a mobile device or navigation device is placed in the field of view to display driving information, then the driver can obtain driving information, but the driving safety is affected due to obstruction of the field of view
Solution Approach 1:
The patent uses the windshield as an intermediary medium to project driving information. Instead of placing displays directly in the driver's field of view, the information is projected onto the windshield which serves as a mediator between the information source and the driver's eye, allowing information delivery without obstructing the natural field of view
Solution Approach 2:
The patent transitions from two-dimensional display surfaces (mobile devices, navigation screens) to a three-dimensional spatial projection on the windshield. By projecting information onto the transparent windshield surface, the system utilizes the third dimension of space to display information without blocking the driver's visual path to the road
2Object-affected harmful factors
If a head-up display projects information onto the front windshield, then the field of view is maintained, but the image brightness is difficult to control - too dark makes it hard to recognize, too bright blocks the field of view
Solution Approach 1:
The patent implements dynamic brightness adjustment of the projected image based on environmental conditions and driving scenarios. The system can adjust the projection brightness in real-time to optimize visibility while maintaining field of view, preventing both too-dark images that are hard to recognize and too-bright images that block the field of view
Solution Approach 2:
The patent changes the brightness parameter of the projected image dynamically. By adjusting the projection intensity and using transparent display technology with controllable light transmission, the system optimizes the balance between image visibility and field of view maintenance, resolving the contradiction between these two parameters
3Loss of information
If conventional displays are used to show driving information, then the information can be displayed, but vehicle network information such as status of other vehicles on the driving route cannot be integrated
Solution Approach 1:
The patent creates a universal display system that can integrate multiple information sources including traditional navigation information and vehicle network information about other vehicles. The transparent display on the windshield serves as a multi-functional platform that consolidates various data sources into a single unified interface, enhancing the system's adaptability and versatility
