Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication challenges arise in vehicle systems due to the length of the vehicles and obstructions such as tunnels, mountains, and buildings, which can lead to signal loss or interference, affecting the reliability of control signals between vehicles, particularly in systems like rail vehicles or fleets of automobiles.
Innovation Solution
A communication system with multiple modes, where a first communication controller can operate to control vehicle movement without repeating signals, monitor and repeat control signals at different frequencies, and switch modes based on identification signals to ensure effective communication, using repeaters to maintain signal strength and clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle system uses a single communication frequency, then the device complexity is reduced, but the communication reliability deteriorates due to signal interference and obstructions
Solution Approach 1:
The patent applies parameter changes by switching between different communication frequencies (parameters) based on environmental conditions. The system monitors signal quality and dynamically changes the operating frequency to avoid interference from tunnels, mountains, and buildings, thereby maintaining communication reliability without requiring multiple simultaneous communication systems
Solution Approach 2:
The communication system implements dynamics by transitioning between different operational modes (first mode without signal repetition, second mode with signal repetition at different frequencies, third mode with selective frequency monitoring) based on real-time communication conditions. This dynamic adaptation allows the system to optimize reliability while managing complexity through conditional logic rather than permanent multi-frequency infrastructure
2Reliability
If the vehicle system operates in a second mode monitoring different frequencies, then the communication reliability improves, but the use of energy increases due to continuous frequency monitoring and signal repetition
Solution Approach 1:
The system dynamically switches between operational modes based on communication needs. In the second mode, the communication controller monitors multiple frequencies and repeats signals only when necessary, rather than continuously operating at maximum monitoring capacity. This dynamic approach maintains reliability while reducing energy consumption during periods when communication conditions are adequate
Solution Approach 2:
The system changes operational parameters by adjusting which frequencies are monitored and when signal repetition is activated. Rather than maintaining constant high-energy monitoring of all frequencies, the system adapts its monitoring and repetition activities based on detected communication conditions, optimizing the balance between reliability and energy usage
3Reliability
If the communication controller repeats control signals at different frequencies, then the communication clarity improves, but the device complexity increases due to multiple frequency monitoring and mode switching
Solution Approach 1:
The communication controller is designed with multi-functionality to perform multiple roles: it can operate in first mode without signal repetition, second mode with multi-frequency monitoring and repetition, and third mode with selective frequency monitoring. This universal design allows a single controller to handle various communication scenarios, improving clarity while managing complexity through consolidated functionality rather than separate dedicated systems for each mode
Solution Approach 2:
The controller implements dynamic mode switching based on communication conditions. Rather than requiring separate hardware for each operational mode, the controller dynamically activates the appropriate functionality (signal repetition, frequency monitoring, or simple transmission) based on real-time conditions, achieving communication clarity while avoiding the complexity of permanently configured multi-mode systems

AI summary
A system is provided that may include a first communication controller that may communicate with a vehicle system formed from two or more vehicles. The first communication controller may operate in different modes, including a first mode to control movement of the vehicle system without repeating any control signals communicated between the vehicles, and in a second mode to monitor different frequencies for receipt of the control signals, receive and repeat a first control signal of the control signals at a first frequency, and receive and repeats a second control signal of the control signals at a second frequency. The first communication controller may also operate in a third mode in which the first communication controller may monitor the first frequency but not the second frequency for the first control signal, receives the first control signal at the first frequency, and repeats the first control signal at the first frequency.
