Vehicle Exterior Display for Dynamic License Plate Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current license plates are static and require replacement for updates, leading to inconvenience and potential loss of information, while dynamic displays on vehicles do not provide the same functionality as static plates.
Innovation Solution
A display system on vehicles that includes a processor, display, vehicle speed sensor, communication device, and trigger device, allowing for multiple operational modes to render vehicle identification and registration information, as well as additional content, with improved updateability and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a static license plate is used, then the vehicle identification information is permanently displayed, but updating the information requires manufacturing a new plate which is time-consuming and inconvenient
Solution Approach 1:
The patent applies a dynamic display system that can change and update vehicle identification information electronically without requiring physical replacement of the license plate. The display controller receives updates from remote systems and dynamically changes the displayed content, eliminating the need for manual plate replacement and significantly reducing update time.
Solution Approach 2:
The patent replaces the traditional mechanical license plate system with an electronic display system. Instead of physically manufacturing and installing new metal plates, the system uses electronic components (display, controller, power management) that can be updated remotely through digital communication, substituting mechanical processes with electronic ones.
2Adaptability or versatility
If a dynamic display is used on the vehicle exterior, then additional information can be displayed and updates are easier, but the display may consume excessive power and may not maintain visibility comparable to static plates
Solution Approach 1:
The patent implements a power management system that periodically activates the display only when needed (e.g., when the vehicle is stationary or when information updates are required) rather than maintaining continuous operation. This periodic activation significantly reduces overall power consumption while ensuring visibility when the display is active.
Solution Approach 2:
The patent adjusts display parameters such as brightness, contrast, and activation timing based on environmental conditions and vehicle state. The system changes these parameters dynamically to optimize visibility while minimizing power consumption, adapting to different operating scenarios.
3Adaptability or versatility
If stickers are used on the license plate for registration information, then updates can be made by replacing stickers, but stickers can be removed, stolen, or detach prematurely causing loss of important information
Solution Approach 1:
The patent replaces the physical sticker system with an electronic display system that shows registration information digitally. This eliminates the vulnerabilities of physical stickers (theft, removal, detachment) by using an electronically controlled display that can securely present information without physical media that can be stolen or removed.
Solution Approach 2:
The patent creates a digital copy of the registration information displayed on the electronic display rather than using physical stickers. This digital representation can be updated and controlled remotely, providing the same information function without the security vulnerabilities of physical stickers.

AI summary
A display system for use on the exterior of a vehicle having a display and a processor. The processor is configured to determine when the vehicle is stopped or in motion, such that the processor directs the display system to display an image based on that determination.
