Innovation Solution
A bidirectional communication system using a combination of wireless, wired, and physical communication lines, featuring an authentication code generation module and a code processing module, which sends and processes identification and encryption information via pressure signals or digital data, ensuring secure and reliable communication by verifying the correct vehicle interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If wireless communication interface is used for intervehicle communication, then data rate between vehicles is improved, but security and reliability of authentication and identification data exchange deteriorates
Solution Approach 1:
The patent introduces a pneumatic communication line as an intermediary channel for exchanging authentication and identification data between the truck and trailer. This physical mediator ensures that sensitive data is transmitted through a dedicated, controlled pathway rather than through wireless channels, thereby maintaining security and reliability while still enabling high-speed wireless communication for other purposes.
Solution Approach 2:
The communication system is segmented into different channels: wireless communication for general data exchange and high-speed transmission, and pneumatic communication specifically for authentication and identification data. This segmentation allows each channel to be optimized for its specific function, with the pneumatic channel providing secure, reliable transmission for critical security data.
2Speed
If authentication and identification data are exchanged wirelessly, then communication speed is improved, but risk of unauthorized access and harmful interference increases
Solution Approach 1:
A pneumatic communication line serves as a secure intermediary for transmitting authentication and identification data. This physical channel is inherently more resistant to unauthorized access and harmful interference compared to wireless channels, as it requires direct physical connection between the truck and trailer, thereby eliminating the risk of remote hacking or interference.
Solution Approach 2:
The system uses the pneumatic line to transmit copies of authentication and identification data separately from the wireless channel. This creates redundant transmission paths where critical security data is copied and sent through a secure physical medium, ensuring that even if the wireless channel is compromised, the authentication data remains protected.
3Device complexity
If only wireless communication is used, then system complexity is reduced, but reliability of vehicle identification and authentication deteriorates
Solution Approach 1:
The communication system is divided into wireless and pneumatic segments, with each serving specific functions. The pneumatic segment is dedicated to authentication and identification, providing reliable verification, while the wireless segment handles general communication. This functional segmentation ensures high reliability for critical operations without making the entire system unnecessarily complex.
Solution Approach 2:
The system implements bidirectional communication through the pneumatic line, enabling feedback mechanisms for verifying authentication and identification. The trailer can send confirmation signals back to the truck through the pneumatic channel, creating a reliable feedback loop that verifies successful authentication and ensures the correctness of vehicle identification.
