Rail Vehicle Configuration Profiles and Virtual Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for configuring and changing operating parameters in rail vehicles are complex, time-consuming, and prone to errors, requiring precise processes and qualified personnel, which can lead to safety issues and inefficiencies, especially when adapting to different routes, infrastructure, or customer-specific requirements.
Innovation Solution
A system that combines operating parameters and rules into profiles, allowing for easy selection, activation, and deactivation of these profiles using a data processing unit with a selection unit, input unit, and reception unit, enabling rapid and error-free configuration of vehicle fleets or individual vehicles, with options for manual, automatic, or semi-automatic profile changes.

Engineering Contradiction Analysis
1Reliability
If operating parameters are changed using traditional precise prescribed change processes, then safety is maintained, but configuration changes become time-consuming and complex
Solution Approach 1:
The patent pre-validates configuration changes by simulating them in a virtual model before actual implementation. The configuration model is updated with proposed changes, and system behavior is simulated to detect errors beforehand. This preliminary validation ensures safety while enabling faster actual deployment since the changes have already been verified.
Solution Approach 2:
The patent creates a virtual copy of the rail vehicle's configuration system. Changes are first applied to this virtual model rather than the actual physical system. The virtual configuration model mirrors the real system's structure and relationships, allowing error-free testing and validation before committing changes to production, thus maintaining safety while reducing time constraints.
2Reliability
If configuration changes are made by qualified personnel following precise processes, then error probability is reduced, but operational complexity increases
Solution Approach 1:
The system performs self-validation through automated simulation and error detection mechanisms. When configuration changes are proposed, the system automatically simulates their effects and detects potential errors without requiring manual verification by qualified personnel. This self-service approach reduces error probability while simplifying the operational process.
Solution Approach 2:
The patent implements a feedback mechanism where the virtual configuration model provides immediate information about potential errors in proposed changes. The system simulates system behavior and feeds back error messages if conflicts are detected, allowing operators to correct issues before implementation. This automated feedback reduces both error probability and process complexity.
3Productivity
If fleet-wide configuration changes are implemented simultaneously, then efficiency is improved, but risk of systematic errors increases
Solution Approach 1:
The patent validates configuration changes in the virtual model before fleet-wide deployment. By pre-testing changes in the virtual configuration model and detecting errors beforehand, the system enables safe simultaneous implementation across the entire fleet, achieving high efficiency without propagating systematic errors.
4Reliability
If detailed validation processes are performed for each configuration change, then reliability is maintained, but productivity decreases
Solution Approach 1:
The patent uses a virtual copy of the configuration system to perform detailed validation. All rigorous checks and simulations are executed in this virtual model rather than on the actual system. This allows comprehensive reliability validation without impacting real-world productivity, as the validation occurs in parallel in the virtual environment.
Solution Approach 2:
The system performs detailed validation in advance in the virtual configuration model before actual deployment. By completing all necessary checks, simulations, and error detections beforehand, the patent ensures configuration reliability while enabling rapid actual implementation, thus maintaining productivity.
