Innovation Solution
A motor vehicle electronics device with a first interface for connecting to an ID token, using a PKI certificate for secure authentication and data transfer, and bi-stable displays for displaying data without continuous power, allowing contactless updating of license numbers via RFID and secure cryptographic methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical license plates are used and replaced, then license number identification is possible, but resource waste and administrative burden increase
Solution Approach 1:
The patent replaces physical license plates with electronic ID tokens that contain digital copies of license number data. The ID token stores the license number in its memory, allowing multiple readings without physical replacement. This eliminates the need to create and dispose of new physical plates while maintaining reliable identification.
Solution Approach 2:
The patent substitutes the mechanical system of physical license plates with an electronic system. The ID token uses electronic memory to store license number data, and RFID technology enables contactless reading of this data by authorized devices, replacing the need for physical handling and replacement of plates.
2Adaptability or versatility
If physical license plates are replaced, then updated license numbers can be displayed, but time and administrative resources are consumed
Solution Approach 1:
The patent implements preliminary action by pre-storing the license number data in the ID token's memory before any display or update operation is needed. When a license number change occurs, the updated number is simply written to the token's memory, eliminating the need for physical replacement and reducing administrative processing time.
Solution Approach 2:
The patent introduces dynamics by enabling the license number data in the ID token to be dynamically updated and changed. The system allows the stored license number to be modified when needed, providing adaptability without requiring physical replacement of the entire plate, thus reducing time consumption.
3Ease of operation
If data is stored in external configuration units and transmitted via infrared, then configuration is possible, but security and reliability are reduced
Solution Approach 1:
The patent replaces the infrared transmission mechanism with RFID technology. The ID token contains an RFID chip that can be read contactlessly by authorized devices, eliminating the need for complex infrared transmission and configuration units while improving security and reliability of data communication.
4Ease of operation
If continuous power is supplied to display apparatus, then data can be displayed, but energy consumption increases
Solution Approach 1:
The patent uses bi-stable display technology that creates a persistent visual copy of the license number data. Once the display is written with data, it maintains this visual state without requiring continuous power supply, significantly reducing energy consumption while preserving the display capability.
