Vehicle Rear Display Relay for Visual Traffic Information Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for distributing information to vehicles rely on radio waves, which have limitations and have not been effectively replaced by alternative carrier mediums.
Innovation Solution
A vehicle equipped with a drive recorder, an external display device, and a control unit that captures and analyzes video data to display specific patterns on the external display device, allowing information to be transmitted to subsequent vehicles without using radio waves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If radio waves are used as carrier medium for information distribution, then information can be transmitted to succeeding vehicles, but the amount of information that can be transmitted is limited and reliability is reduced
Solution Approach 1:
The patent replaces radio wave-based electromagnetic communication with a visual optical system using display devices and cameras. Information is transmitted by displaying visual patterns (such as LED arrangements or display screen content) that can be captured by cameras in succeeding vehicles, converting wireless electromagnetic communication into a visual-optical transmission mechanism.
Solution Approach 2:
The patent uses visual patterns and images as copies of information that can be transmitted and reproduced across multiple vehicles. The display device creates visual representations of information (such as traffic conditions, accident scenes, or navigation data) that can be captured, stored, and re-transmitted as image copies, enabling information replication without relying on radio wave bandwidth limitations.
2Loss of time
If radio waves are used for information distribution, then communication can be established, but immediacy of information transmission is reduced
Solution Approach 1:
The patent employs preliminary action by having vehicles continuously capture and store information using cameras and display devices before it is needed. When a vehicle encounters important information (such as traffic accidents or congestion), it immediately displays and transmits this information to succeeding vehicles, allowing downstream vehicles to receive and act on the information without waiting for radio wave communication delays.
Solution Approach 2:
The system enables self-service information transmission where each vehicle independently captures, displays, and transmits information without requiring centralized radio communication infrastructure. Vehicles autonomously detect information needs, capture relevant data through their cameras, and transmit it to succeeding vehicles through their display devices, creating a decentralized self-organizing information distribution network.
Data Source
AI summary
The vehicle includes a drive recorder that captures an image of the front of the vehicle, an external display device that performs display toward the rear of the vehicle, and a control unit. When a specific pattern is included in the video captured by the drive recorder, the control unit causes the external display device to display the same pattern as the pattern.
