Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telematics units for commercial vehicles face challenges in transmitting status information when in areas without cellular network coverage, such as tunnels or buildings, leading to gaps in monitoring capabilities.
Innovation Solution
A method for establishing a connection between a mobile device and a telematics unit using a first wireless communication network, involving acquiring telematics unit identification information, obtaining authentication information, determining an authentication key, and generating a connection setup message to securely establish a direct connection, even in areas with limited or no cellular coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If telematics units use cellular network for communication, then status information can be transmitted to remote server, but communication fails in areas without cellular coverage such as tunnels or buildings
Solution Approach 1:
The patent introduces a wireless access point as an intermediary communication device that relays data between the telematics unit and the external network. When cellular coverage is unavailable, the access point receives data from the telematics unit via short-range wireless communication and forwards it to the server, enabling continuous monitoring in areas without cellular coverage.
Solution Approach 2:
The patent adds a secondary communication dimension by implementing both cellular network communication and short-range wireless communication (WiFi, Bluetooth) simultaneously. This multi-dimensional communication approach ensures that if one communication path fails (cellular), another path (short-range wireless via access point) can be used.
2Adaptability or versatility
If direct wireless connection is established between mobile device and telematics unit, then continuous monitoring is enabled without cellular coverage, but secure authentication and connection establishment become complex
Solution Approach 1:
The patent implements preliminary authentication by having the telematics unit generate and store connection credentials (SSID, password, or QR code) before the mobile device needs to connect. The mobile device can scan the QR code or automatically receive credentials, which simplifies the connection establishment process while maintaining security through pre-configured authentication mechanisms.
Solution Approach 2:
The patent uses QR codes as a visual copy of the connection credentials. Instead of manually entering complex authentication information, the mobile device's optical sensor captures the QR code displayed by the telematics unit, which contains encoded connection information. This copying mechanism simplifies the connection process while ensuring accurate transmission of authentication data.
3Reliability
If authentication information is obtained through user input, then security is maintained, but user interaction time increases connection establishment duration
Solution Approach 1:
The patent uses QR codes to copy and transmit authentication information visually. The mobile device's optical sensor captures the QR code displayed by the telematics unit, which contains encoded connection information. This eliminates the need for manual user input while maintaining security, as the authentication credentials are automatically extracted from the scanned code.
Solution Approach 2:
The system enables self-service connection establishment where the mobile device automatically scans the QR code, extracts the connection credentials, and establishes the wireless connection without requiring user intervention for each step. The authentication process is automated while maintaining security through the encoded credentials in the QR code.
