Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Baggage handling systems face challenges with baggage tampering and theft due to the difficulty in surveillance of conveyor belts in closed and isolated areas, where unauthorized personnel can tamper with or steal luggage without being detected.

Innovation Solution

A baggage handling system with integrated cameras and controllers that perform video analytics to detect suspicious activities, raise alarms, and track luggage, using object classification and template matching models to identify tampering or theft.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If human personnel surveillance is used on conveyor belts, then security monitoring is provided, but it becomes difficult due to long distances and closed isolated areas

Engineering Contradiction:

Improvesecurity monitoringVSAvoidsurveillance difficulty

Core Design Contradiction:

ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent replaces human mechanical surveillance with an automated video analytics system that uses cameras and image processing algorithms to detect baggage tampering and theft events on conveyor belts, eliminating the difficulty of human monitoring in long-distance and isolated areas

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service security monitoring by automatically detecting suspicious activities through video analytics and raising alarms without requiring continuous human intervention, allowing the system to monitor itself and alert authorities autonomously

Inventive Principle:

Principle #25Self-service

2Difficulty of detecting and measuring

If automated video analytics system is implemented, then detection capability is improved, but device complexity increases

Engineering Contradiction:

Improvedetection capabilityVSAvoidsystem complexity

Core Design Contradiction:

Difficulty of detecting and measuringVSDevice complexity

Solution Approach 1:

The patent segments the video analytics system into distinct functional modules including camera subsystem, image processing subsystem, template matching subsystem, and alarm generation subsystem, making the complex system more manageable and easier to implement

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary action by creating template images of legitimate baggage appearances during normal operation, which are then used to detect tampering events, simplifying the detection process and reducing real-time computational complexity

Inventive Principle:

Principle #10Preliminary action

AI summary

A baggage handling system is described. The baggage handling system may include cameras. Video from the cameras may be automatically monitored. The video may be automatically monitored in real time across the entire journey of the baggage. The baggage handling system may provide an automated approach to identify theft of airport bags\luggage without manual effort required by humans. The bags may then be safely transported through an airport without theft or tampering. The automated surveillance and responding system may not depend on airport staff to monitor for baggage theft. The automated surveillance and responding system may detect multiple types of baggage theft/tampering.
