Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Trains lack the capability to record information about their condition and the areas traversed, leading to potential accidents due to undetected issues, and replacing existing fleets with sensor-equipped trains is impractical due to high costs.
Innovation Solution
Attach self-contained train data recording devices with sensors like GNSS, IMU, and cameras to existing trains, allowing data aggregation and analysis to identify potential issues and optimize train performance without complete replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If existing train fleets are replaced with sensor-equipped trains, then data collection capability is improved, but implementation cost increases
Solution Approach 1:
The system divides the train fleet into two segments: existing trains without sensors and new sensor-equipped trains. This allows incremental deployment where sensor devices can be attached to individual trains as needed, rather than requiring complete fleet replacement. The segmentation enables cost-effective data collection by processing only a portion of the fleet at a time.
Solution Approach 2:
The patent implements partial action by equipping only a subset of trains with sensor devices rather than the entire fleet. This approach provides sufficient data collection capability for analysis and improvement while avoiding the excessive cost of universal deployment. The system achieves meaningful results with partial coverage.
2Reliability
If comprehensive sensor equipment is installed on trains, then safety monitoring is improved, but device complexity increases
Solution Approach 1:
The sensor device is designed as a universal multi-functional unit that can be attached to any train type. It performs multiple functions including collecting sensor data, capturing media (images/video), storing data locally, and transmitting data wirelessly. This consolidation of multiple functions into a single device reduces overall system complexity while maintaining comprehensive safety monitoring capabilities.
Solution Approach 2:
The sensor device is self-contained with onboard memory for data storage and wireless communication capabilities for automatic data transmission. The device manages its own operations including data collection, storage, and transmission without requiring constant external intervention, thereby simplifying the overall system architecture while ensuring reliable safety monitoring.

AI summary
Example embodiments relate to train data recorder and event notification systems and techniques for using such systems. An example device includes a housing configured to attach onto a train with multiple sensors located in the housing, such as a Global Navigation Satellite System (GNSS) receiver, an inertial measurement unit (IMU), and a camera that can capture images of an environment outside the housing. The device also includes a memory and a processor located inside the housing where the processor is configured to receive sensor data from at least one of the sensors and store the sensor data on the memory. A central computing system can aggregate location-based data generated by train data recording devices positioned on one or multiple trains and map the data to the network of train tracks to detect trends and provide insights to operators.
