Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-vehicle systems, the manual authorization of communication devices to prevent unintended operation due to wireless communication interference from other systems is time-consuming and prone to errors, leading to potential unsafe operations.
Innovation Solution
A communication system where devices can operate in lead, repeater, or trail modes, allowing remote switching based on status information to ensure only authorized communications control vehicle movements, using a code to identify lead devices and prevent interference from other systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual authorization of communication devices is implemented to prevent unintended operation, then system safety is improved, but the time required to deploy and operate the system increases
Solution Approach 1:
The system performs preliminary authorization actions by assigning unique identifiers to lead vehicles and pre-configuring communication devices with authorization protocols. When a vehicle joins the platoon, its communication device is automatically authorized based on these pre-established credentials, eliminating the need for manual authorization during deployment.
Solution Approach 2:
Communication devices automatically perform authorization checks and authenticate with lead vehicles using embedded credentials and protocols. The system self-manages the authorization process without requiring external manual intervention, thereby reducing deployment time while maintaining security.
2Reliability
If manual authorization of communication devices is implemented, then prevention of unintended operation is improved, but operational efficiency deteriorates
Solution Approach 1:
The system implements self-service authorization where communication devices automatically authenticate with lead vehicles using unique identifiers and cryptographic protocols. This automated process prevents unintended operation while maintaining high operational efficiency by eliminating manual authorization steps.
Solution Approach 2:
The authorization system incorporates continuous feedback mechanisms where communication devices verify lead vehicle credentials and platoon membership status in real-time. This automatic verification prevents unintended operations from unauthorized vehicles while maintaining smooth operational flow without manual intervention.
3Reliability
If communication devices are manually authorized, then security against interference from other systems is improved, but the complexity of the operation increases
Solution Approach 1:
Communication devices automatically perform security checks and authenticate with lead vehicles using embedded cryptographic protocols and unique identifiers. This self-service approach maintains strong security against interference from other systems while eliminating the need for operators to manually configure security settings.
Solution Approach 2:
The authorization system uses universal cryptographic protocols and standardized communication interfaces that work across all vehicles in the platoon. This multi-functional approach provides robust security while simplifying operations, as the same automated process handles all authorization and security verification tasks uniformly.

AI summary
A communication system may include communication devices configured to be onboard vehicles in a multi-vehicle system. Each of the communication devices may operate in a lead mode, a repeater mode, or a trail mode. The communication devices operating in the lead mode may transmit a command signal to control movement of the multi-vehicle system. The communication devices operating in the repeater mode may re-transmit the command signal received from the one or more communication devices operating in the lead mode. The communication devices operating in the trail mode may receive the command signal received from the one or more communication devices operating in the lead mode or in the repeater mode. Each of the communication devices may be remotely switched between the lead mode or the trail mode to the repeater mode.
