Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current diagnostic interfaces for commercial vehicles rely on wired communication paths, which are inadequate for transferring large amounts of data, leading to increased maintenance and diagnostic task durations and costs, potentially exceeding production cycle times.
Innovation Solution
Establishing a wireless communication path between a commercial vehicle device and a diagnostic or maintenance device by sending a communication path request and bonus messages via a wired connection, allowing for the construction of a wireless network connection using standardized protocols like WLAN, ZigBee, or Bluetooth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wired communication path is used for data transmission, then connection stability is improved, but data transmission speed deteriorates
Solution Approach 1:
The patent uses the wired communication path as an intermediary to securely exchange establishment messages (including authentication and configuration data) before transitioning to wireless communication. This allows the wired connection to serve its strength (stable authentication) while enabling the wireless connection to handle high-speed data transfer.
Solution Approach 2:
The patent performs preliminary authentication and connection establishment actions over the wired communication path before switching to wireless mode. The establishment messages are exchanged in advance through the stable wired connection, preparing the wireless link for immediate high-speed data transmission without security risks.
2Reliability
If a wired communication path is used for data transmission, then security is improved, but transmission capacity deteriorates
Solution Approach 1:
The wired communication path acts as a secure intermediary for exchanging sensitive establishment messages (authentication credentials, security keys, configuration parameters). Once authentication is complete through this secure channel, the wireless path is configured with appropriate security parameters, enabling both high capacity and security for subsequent data transfer.
Solution Approach 2:
Security-related establishment messages are exchanged in advance through the secure wired connection before wireless communication begins. This preliminary security setup includes authentication, authorization, and encryption key exchange, allowing the wireless connection to immediately handle large data volumes with established security measures in place.
3Speed
If wireless communication path establishment messages are sent via wireless path, then transmission speed is improved, but security deteriorates
Solution Approach 1:
The patent performs the critical security-related message exchange (authentication, authorization, encryption setup) in advance through the secure wired communication path before any wireless communication occurs. This preliminary action ensures that security credentials are established through a trusted channel, preventing security vulnerabilities in the subsequent wireless transmission.
Solution Approach 2:
The wired communication path serves as a secure intermediary medium for exchanging sensitive establishment messages. This intermediary role allows the system to leverage the security strengths of wired communication for authentication while enabling the speed advantages of wireless communication for actual data transfer.

AI summary
A method for establishing a wireless communication path between a first device for a commercial vehicle and a second device is described, the method comprising: - receiving a communication path request message from the second device at the first device, wherein the communication path request message is received at the first device via a wired communication path between the first device and the second device; - sending a communication path establishment message from the first device to the second device, wherein the communication path establishment message is sent via the wired communication path, and wherein the communication path establishment message represents one or more pieces of information for establishing the wireless communication path between the first device and the second device.
