Mobile Vehicle Device Decentralized Data Initialization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toll collection systems require central registration of vehicle data, leading to inefficiencies and errors during vehicle changes, especially for mobile devices used across different vehicles, as they necessitate long-range communication and manual data entry, which can be error-prone and inconvenient.
Innovation Solution
A method where a mobile vehicle device reads vehicle data from a transponder attached to the vehicle using a reading device, allowing for decentralized storage and initialization, enabling the vehicle data to be linked directly to the device without central registration, ensuring secure and easy handling of vehicle data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If central registration of vehicle data is used, then data security and control are improved, but system complexity and initialization time increase
Solution Approach 1:
The patent extracts the vehicle data storage function from the central registration system and places it in the mobile device's local memory. The mobile device stores vehicle data (VIN, license plate, etc.) locally without requiring continuous central registration, thereby reducing system complexity while maintaining data security through local encryption and authentication mechanisms.
Solution Approach 2:
The patent introduces a transponder as an intermediary component that stores vehicle data and communicates with both the mobile device and the fee collection system. This intermediary enables decentralized data storage while maintaining secure communication channels, allowing the system to operate without direct central registration for each operation.
2Measurement precision
If manual data entry during vehicle changes is required, then data accuracy can be verified, but time consumption and error rates increase
Solution Approach 1:
The patent implements preliminary action by pre-storing vehicle data in the transponder before the mobile device needs to access it. When a vehicle change occurs, the mobile device automatically reads the pre-stored data from the transponder via wireless communication, eliminating the need for manual data entry and verification while ensuring data accuracy through automated validation.
Solution Approach 2:
The patent replaces the mechanical/manual data entry process with an automated wireless communication system. The mobile device uses a wireless interface to automatically transmit and verify vehicle data with the transponder, substituting manual verification with automated electronic validation that is both faster and more accurate.
3Adaptability or versatility
If mobile devices are used across multiple vehicles, then device versatility is improved, but data management complexity increases
Solution Approach 1:
The patent segments the data management function by separating vehicle-specific data (stored in the transponder) from device-specific data (stored in the mobile device). Each vehicle has its own transponder with dedicated data storage, allowing the mobile device to switch between vehicles by simply reading from different transponders without managing complex centralized data structures.
Solution Approach 2:
The patent uses copying by creating a data copy in the transponder that mirrors the vehicle information. Instead of the mobile device maintaining complex links to central databases for each vehicle, it simply reads a copied version of the vehicle data from the transponder, enabling easy vehicle switching while keeping data management simple.
4Reliability
If centralized fee collection system is used, then fee management control is improved, but communication requirements and system overhead increase
Solution Approach 1:
The patent extracts the fee collection function from the centralized system and implements it directly in the mobile device. The mobile device stores fee-relevant data locally and automatically transmits only essential fee information to the fee collection system, reducing communication overhead while maintaining centralized control through selective data transmission and processing.
