Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for testing and maintaining locomotives are labor-intensive, time-consuming, and prone to errors, limiting the quantity and accuracy of data collected, which increases operational costs and downtime.
Innovation Solution
A computer-implemented system that allows multiple locomotives to be tested simultaneously through electrical communication, using a microprocessor and MU control driver to synchronize testing sequences, download operating parameter data, and analyze it against acceptable limits, enabling efficient data collection and analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual data collection and analysis methods are used, then technicians can perform testing and maintenance on locomotives, but the process becomes labor-intensive and time-consuming
Solution Approach 1:
The patent replaces manual mechanical data collection processes with an automated computer-based system. The system automatically retrieves data from locomotive databases, performs analysis, and generates reports without requiring technicians to manually enter and process data, thereby significantly reducing labor intensity and time requirements
Solution Approach 2:
The system enables self-service by allowing the computer to autonomously collect, analyze, and interpret locomotive operational data. The automated system performs testing and diagnostic functions independently, reducing reliance on manual technician intervention and improving overall maintenance productivity
2Measurement precision
If manual data entry and analysis is performed, then testing and maintenance can be conducted, but errors increase and accuracy decreases
Solution Approach 1:
The patent eliminates manual data entry and analysis processes by implementing an automated computer-based system that directly retrieves data from locomotive databases and performs analysis algorithmically. This substitution removes human error sources and significantly improves both the precision of measurements and the reliability of diagnostic results
3Productivity
If one locomotive is tested at a time with manual interface, then detailed analysis can be performed, but the quantity of data collected is limited and the process is slow
Solution Approach 1:
The patent implements a universal computer-based system capable of simultaneously testing and analyzing multiple locomotives through a single interface. The system can retrieve and analyze operational data from multiple locomotive databases concurrently, significantly increasing both the throughput of locomotives tested and the total quantity of data collected without requiring additional manual resources
Data Source
AI summary
A computer-implemented system and method of contemporaneously testing a respective system on-board each of a plurality of locomotives with a common user interface where the locomotives are in electrical communication with one another for transmitting electronic signals among the locomotives. An electronic signal may be transmitted to the plurality of locomotives instructing a respective on-board computer of each locomotive to synchronously engage a self-load sequence. An electronic signal may be transmitted to the plurality of locomotives instructing a respective engine of each locomotive to execute a testing sequence. Operating parameter data associated with the respective systems may be downloaded from each of the plurality of locomotives through the common user interface to a database engine to determine whether the downloaded operating parameter data is within acceptable operating limits.
