Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current tracking and logistics systems for cargo are inefficient, costly, and unsafe due to manual scanning of RFID tags on railcars, with limitations in distance and frequency leading to inaccurate and untimely data aggregation, which affects railcar switching operations and overall railyard operations.

Innovation Solution

A dynamic communication method for smart tags that enables inter-tag communication, allowing for the detection and transmission of telemetric and location data across a network of tags, even at distances greater than 60 feet, using a system of miniaturized smart tags, anchor systems, and gateway systems to create an inventory map for real-time data visualization and logistical control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual scanning of RFID tags is used, then workers can collect cargo data, but the process is time-consuming and unsafe

Engineering Contradiction:

Improvecargo data collection speedVSAvoidworker safety

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces manual mechanical scanning operations with an automated optical imaging system. Cameras capture images of RFID tags on railcars, and image processing algorithms automatically extract cargo data, eliminating the need for workers to physically approach and scan each tag manually.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service data collection where the imaging system and processing algorithms automatically capture, process, and extract cargo information without human intervention. The system serves itself by using computer vision to identify and read RFID tag data from images.

Inventive Principle:

Principle #25Self-service

2Measurement precision

If standard RFID transmission frequency is used, then tags can be read, but distance is limited to 10 feet

Engineering Contradiction:

Improvetag detection accuracyVSAvoiddetection distance

Core Design Contradiction:

Measurement precisionVSLength of stationary object

Solution Approach 1:

The patent transitions from radio frequency detection to optical dimension detection. Instead of using RFID radio waves with limited range, the system uses cameras to capture optical images of tags from a distance, and image processing extracts the data. This dimensional shift from electromagnetic radio waves to optical imaging enables detection beyond 10 feet.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Reliability

If individual tag scanning is performed, then each cargo can be tracked, but data aggregation is inaccurate and untimely

Engineering Contradiction:

Improvedata aggregation accuracyVSAvoiddata collection time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent merges multiple tag detections into a single comprehensive image capture process. Instead of scanning tags individually, the system captures images of multiple railcars simultaneously and processes all tag data together, achieving accurate and timely aggregation of cargo information from multiple sources in parallel.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system enables continuous data collection by capturing images of railcars as they move through the yard. The continuous imaging and processing workflow eliminates gaps in data aggregation, providing timely and accurate cargo tracking information without interruption.

Inventive Principle:

Principle #20Continuity of useful action

4Productivity

If RFID tags are placed on mobile railcars, then cargo can be tracked, but real-time data transmission is not supported

Engineering Contradiction:

Improvereal-time reporting capabilityVSAvoidreal-time cargo data

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The system performs preliminary action by capturing images of RFID tags before the railcars move to their next positions. By proactively imaging tags while railcars are visible and accessible, the system extracts and stores cargo data in advance, enabling real-time reporting as the data is already captured and processed.

Inventive Principle:

Principle #10Preliminary action

AI summary

The disclosed methods include: detecting data associated with a first tag comprised in the tag network; resolving the data to generate resolved data associated with a plurality of tags in the tag network including the first tag and a second tag; determining the second tag based on the resolved data; and extracting or determining, using the resolved data: first telemetric data associated with the first tag, first location data associated with the first tag, second telemetric data associated with the second tag, and second location data associated with the second tag. The methods also include formatting the first telemetric data, the first location data, the second telemetric data, and the second location data to generate an inventory map associated with the first mobile or stationary cargo and the second mobile or stationary cargo; and transmitting the inventory map to a display device configured to visualize the inventory map.
