Vehicle Message Display for Specific Driver-to-Driver Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication methods between drivers on the road, such as hand gestures and horn honking, lack specificity and often lead to misunderstandings, while modern technologies like smartphones increase distracted driving and hinder effective communication with other road users.
Innovation Solution
An electronic driver courtesy system with a vehicle-mounted emissive display and smartphone integration, allowing drivers to send specific messages through voice commands, typed inputs, or pre-programmed options, and prioritizing emergency broadcasts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional communication methods (hand gestures, horn honking) are used, then drivers can communicate basic signals, but the communication lacks specificity and leads to misunderstandings
Solution Approach 1:
The patent introduces an electronic display device mounted on the vehicle exterior as an intermediary communication medium. This display acts as a mediator between the driver's intent and other road users, transmitting specific messages (e.g., 'yield', 'thank you', 'wrong way') without requiring direct driver-to-driver interaction. The display converts internal digital messages into visible external signals, resolving the contradiction by providing high-specificity communication through a simple display interface.
2Loss of information
If smartphones and portable electronic devices are used for communication, then drivers can send specific messages, but this increases distracted driving and reduces road safety
Solution Approach 1:
The patent extracts the communication function from the driver's hands by mounting the display device on the vehicle exterior. The driver interacts with a simple interface (button press, voice command, or automatic detection) while the display itself is positioned where it can be seen by other road users. This extraction removes the need for the driver to hold or manipulate a smartphone, eliminating distracted driving while maintaining clear message transmission to other users.
Solution Approach 2:
The system incorporates automatic message transmission capabilities where the display can be activated without continuous driver intervention. Once a message is selected or detected (e.g., through sensors detecting another vehicle's presence or status), the system automatically transmits the appropriate message. This self-service feature reduces driver workload and eliminates the need for continuous interaction with the device, thereby improving safety while maintaining communication clarity.
3Ease of operation
If predefined messages or symbols are displayed on vehicle message displays, then communication between drivers is simplified, but the communication is limited in versatility and specificity
Solution Approach 1:
The patent implements a multi-functional message display system that can present various types of information: predefined symbols (e.g., baby on board), text messages (e.g., 'yield', 'thank you'), and potentially custom messages. The display device serves multiple communication functions - warning, thanking, directing, and informing - all through a single unified interface. This universality allows the system to maintain ease of operation with simple selection methods while providing extensive message variety to cover different driving scenarios and needs.
