Electronic License Plate Frame With E-Paper Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle license plate systems face challenges such as power dependency, inability to display information during power interruptions, and difficulties in displaying static and non-static information, particularly for parking validation and registration, which can lead to compliance issues and increased labor costs.
Innovation Solution
A system comprising a server connected to a wide area network, a data repository, and computerized displays mounted on vehicles, allowing for remote interaction and display of static and non-static information, including vehicle registration, insurance status, and parking validation, using electrophoretic displays that remain operational even when the vehicle is powered off, integrated into license plate frames or other visible locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronically powered license plate frames connected to vehicle infotainment systems are used to display registration information, then information can be displayed dynamically, but the system requires significant power and cannot operate during power interruptions
Solution Approach 1:
The system divides the display functionality into two independent segments: a passive display device that shows static information without power requirements, and an optional active electronic component that provides dynamic updates when power is available. This segmentation allows the system to maintain basic display functionality during power interruptions while enabling enhanced capabilities when powered.
Solution Approach 2:
A server acts as an intermediary between the data repository and the display devices. The server stores information and can push it to either passive displays or active electronic displays, mediating the information flow and allowing flexible deployment depending on power availability and infrastructure presence.
2Use of energy by stationary object
If traditional sticker registration tags are used, then no power is required, but tags are easily lifted and misplaced, causing compliance issues
Solution Approach 1:
The system replaces physical sticker tags with electronic copies of registration information displayed on passive display devices integrated into the license plate frame. These displays show the same registration data as traditional stickers but in a more secure, tamper-resistant format that is difficult to remove or misplace while maintaining power independence.
3Productivity
If electronic displays are integrated into license plate frames to show registration and parking information, then remote management and reduced labor costs are achieved, but the system complexity increases
Solution Approach 1:
The passive display device is designed to serve multiple functions: displaying vehicle registration information, parking validation data, and other compliance-related information. This multi-functionality reduces the need for multiple separate display systems and simplifies the overall architecture while maintaining remote management capabilities through the server infrastructure.
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
This solution reduces labor and costs associated with vehicle-related transactions by enabling remote management and display of critical information, ensuring compliance and convenience through network-connected, power-efficient displays that function independently of the vehicle's power state.
Implementation Method 1
In another embodiment, at least one display may be an electrophoretic display (EPD) which remains operational depicting information when the motor vehicle is powered off

AI summary
Systems, apparatus and methods related to electronic vehicle registration and tag displays, specifically a vehicle license plate frame containing multiple low power e-paper type displays configured to replace the stickers used for vehicle registration and parking authorizations as well as provide indication of purchased parking increments and/or allow for display of advertisement or other messages. The system may also allow the display of driver or vehicle specific information such as the user's driver's license number or insurance at the request of a third party authorities such as the police. The system allows for use of a mobile computing device having software connected with the internet to access a server allowing for communication with various registrations authorities including the DMV, municipal parking authorities, and private parking authorities. Displays may be overwritten and changed depending on the location of the vehicle and need to provide display of certain authorizations.
