Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current railroad track simulators are large, difficult to operate, and only suitable for simulating fewer track lengths due to their larger impedances, making them unsuitable for testing grade crossing predictors and other track circuits effectively.
Innovation Solution
A modular railroad track simulator system comprising smaller, combinable units with varying impedances that can simulate multiple track lengths, featuring test points for easy connection and alteration of simulated conditions, allowing for precise simulation of different track lengths and types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional track simulators with larger impedances are used, then fewer track lengths can be simulated, but the device size is reduced and operation is simplified
Solution Approach 1:
The track simulator is divided into multiple modular units, each capable of simulating a specific track length. These units can be connected in series to simulate longer track lengths or used individually for shorter lengths, providing versatility while maintaining manageable device complexity through standardized modular components
2Adaptability or versatility
If conventional track simulators are used, then simulation capability is limited, but ease of operation is maintained
Solution Approach 1:
The modular track simulator units are designed with universal connection interfaces and standardized configurations that allow them to be easily connected and reconfigured for different simulation scenarios. This multi-functionality enables a single modular unit to serve multiple purposes across different track length requirements while maintaining ease of operation through consistent interface designs
3Ease of operation
If smaller modular simulation units are used, then ease of operation and connection is improved, but individual unit impedance is reduced
Solution Approach 1:
Multiple modular simulation units with smaller individual impedances can be connected in series to achieve the required total impedance for longer track length simulations. This combining approach maintains the ease of operation benefits of smaller modular units while achieving the necessary total impedance through systematic integration of multiple units

AI summary
A system for simulating a railroad track. The system comprises one or more modular track simulation units that are smaller than conventional track simulators and are easy to use with and be connected to a device being tested (e.g., grade crossing predictor). Each track simulation unit may have one of a plurality of impedances associated with a corresponding railroad track length. The units are combinable such that the system can simulate multiple, different track lengths. Each unit has a plurality of test points that can be connected to the device under test and/or used to alter conditions of the simulated track.
