Solution Overview

Problem

The existing methods for measuring and recording the positions of balises in rail vehicle systems are complex, prone to errors, and time-consuming, leading to delays and inefficiencies in operation.

Innovation Solution

A method where rail vehicles determine and transmit balise position information to a central database, continuously updating it, allowing for a self-improving balise position database using sensors and communication devices, thereby enhancing the reliability and efficiency of balise position determination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual measurement methods are used to determine balise positions, then the initial setup can be completed, but the process is laborious, error-prone, and time-consuming

Engineering Contradiction:
Improvebalise position accuracyVSAvoidmeasurement time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system enables self-service measurement where rail vehicles automatically determine balise positions using their own sensor systems (odometry, GPS, inertial measurement units) during normal operation. The vehicles themselves perform the measurement function that previously required manual surveying equipment and personnel, eliminating the need for specialized measurement teams while continuously improving position accuracy through multiple measurements.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The measurement process transitions from a one-time manual activity to continuous automatic measurement during regular rail vehicle operations. Every time a rail vehicle passes a balise, it performs a measurement, allowing the system to continuously accumulate and refine position data without interruption to operational activities.

Inventive Principle:
Principle #20Continuity of useful action

2Reliability

If manual measurement methods are used, then balise positions can be initially recorded, but errors are difficult to detect and correction is laborious

Engineering Contradiction:
Improvebalise position reliabilityVSAvoidmeasurement system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system implements feedback mechanisms where measured balise positions are automatically transmitted to a central database, compared with existing records, and any discrepancies trigger automatic re-measurement or correction protocols. This closed-loop feedback system continuously monitors measurement quality and automatically corrects errors without requiring manual verification processes.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Manual mechanical measurement processes are replaced with automated sensor-based systems including odometry sensors, GPS receivers, and inertial measurement units that electronically determine positions. This substitution eliminates human error in measurement while providing digital data that can be automatically processed and validated by computer systems.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Manufacturing precision

If a traditional database approach is used, then balise information can be stored, but updates are laborious and cause operational delays

Engineering Contradiction:
Improvedatabase accuracyVSAvoiddatabase update efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The database system performs self-updates automatically as rail vehicles transmit new measurement data during normal operations. The central database continuously integrates new information from multiple vehicles without requiring manual intervention or stopping operations, allowing the database to maintain high accuracy while updating efficiently in the background of ongoing activities.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system prepares and validates measurement data in advance during vehicle operations, so that when updates are needed, the corrected information is already ready for immediate implementation. This preliminary processing of measurement data ensures that database updates can be performed quickly without disrupting operational workflows.

Inventive Principle:
Principle #10Preliminary action
