Dynamic Inspection Routing for Baggage Screening Wait Times
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current belongings inspection systems face challenges in efficiently reducing waiting times, as they often require secondary inspections for all detected items, leading to congestion and prolonged wait times.
Innovation Solution
An inspection system that uses electromagnetic waves with wavelengths between 30 micrometers and one meter to detect abnormal states, deciding on-site secondary inspections based on the type of detected object, and guiding individuals to appropriate paths, thereby reducing congestion and wait times by sorting secondary inspections dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If secondary inspection is performed for all detected items, then detection reliability is improved, but waiting time increases and congestion occurs
Solution Approach 1:
The patent segments the inspection process into primary inspection (using electromagnetic waves to detect all items) and secondary inspection (manual verification of suspicious items). This segmentation allows the system to maintain high detection reliability through comprehensive primary screening while reducing waiting time by avoiding mandatory secondary inspection for all detected items, only requiring it for suspicious cases.
Solution Approach 2:
The patent introduces dynamic decision-making where the decision to perform secondary inspection is not fixed but depends on the detection results and risk assessment. The system dynamically adjusts the inspection process based on the type, location, and risk level of detected items, allowing flexible allocation of resources and reducing unnecessary waiting time for low-risk detections.
2Measurement precision
If secondary inspection is performed for all detected items, then detection precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the inspection system into two independent parts: an automated electromagnetic wave detection system for initial screening and a manual secondary inspection system for verification. This segmentation maintains detection precision for suspicious items while simplifying the overall process by using automation for the majority of inspections, reducing the complexity burden on manual operations.
Solution Approach 2:
The patent introduces an intermediate decision-making layer that uses detection results to determine whether secondary inspection is needed. This intermediary layer acts as a filter between the automated detection system and manual inspection, reducing the complexity of the overall system by only engaging manual resources when necessary based on objective criteria.
3Productivity
If dynamic sorting of secondary inspections is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic sorting of secondary inspections based on real-time detection results, risk assessments, and facility conditions. The system dynamically adjusts inspection priorities and routing decisions, improving productivity by directing resources to high-risk cases first while maintaining manageable system complexity through automated decision algorithms that process multiple factors simultaneously.
Solution Approach 2:
The patent changes key parameters such as inspection priority, routing direction, and resource allocation based on detection characteristics and risk levels. By dynamically adjusting these parameters rather than using fixed protocols, the system improves productivity through optimized inspection flow while managing complexity through parameter-based decision logic that can adapt to varying conditions.
