Security Checkpoint Tote Transport for Parallel Scanner Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security checkpoint processes at locations like airports suffer from inefficiencies due to poor utilization rates of scanning machines and security personnel, leading to congestion and increased travel times for individuals.
Innovation Solution
Implementing a system that utilizes computer-controlled vehicles to transport personal items between intake locations, security scanners, and retrieval locations, allowing for parallel processing of individual and baggage screenings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a linear security screening process is used where each traveler lane has its own assigned scanner, then security screening can be performed systematically, but the utilization rates of scanning machines and security personnel are poor and lanes become congested
Solution Approach 1:
The patent segments the security screening process into separate functional modules: personal item intake locations, security scanners, and personal item retrieval locations. Computer-controlled vehicles independently transport items between these modules, allowing each scanner to serve multiple lanes and processes simultaneously, thereby improving utilization rates while maintaining systematic screening.
Solution Approach 2:
The patent introduces computer-controlled vehicles as intermediary transport devices between intake locations, scanners, and retrieval locations. These vehicles decouple the scanning process from fixed lane assignments, enabling scanners to serve multiple travelers concurrently and significantly improving scanner utilization rates without compromising screening reliability.
2Reliability
If a linear security screening process is used with fixed lane assignments, then each traveler can be screened systematically, but travel time through security increases due to congestion and waiting
Solution Approach 1:
The patent implements preliminary actions by having computer-controlled vehicles collect personal items at intake locations before the travelers themselves reach the scanning area. This allows item screening to begin in parallel with traveler processing, reducing overall wait times while maintaining systematic screening procedures.
Solution Approach 2:
The patent ensures continuity of useful action by implementing parallel processing where multiple activities occur simultaneously: travelers undergo personal screening while computer-controlled vehicles independently transport and scan personal items. This continuous parallel operation reduces traveler wait times without compromising the systematic nature of security screening.
3Productivity
If multiple security scanners are deployed in parallel lanes, then more travelers can be screened simultaneously, but the complexity of coordinating and managing multiple lanes increases
Solution Approach 1:
The patent implements universality by designing security scanners that can serve multiple functions and multiple travelers simultaneously through the intermediary vehicle system. Instead of each scanner being dedicated to a single lane, the vehicle-based transport system allows any scanner to process items from any intake location, reducing coordination complexity while maintaining high throughput capacity.

AI summary
Improved security checkpoint includes a security scanning system having multiple personal item intake locations, a security scanner, multiple personal item retrieval locations, and a plurality of computer-controlled vehicles for transporting personal items between the personal item intake locations, the security scanner, and the personal item retrieval locations. Personal items are placed into a tote by an individual, and the computer-controlled vehicles collect the totes containing the personal items, transport the tote to an available security scanner, deposit the tote at the security scanner, and then transport the tote either to a retrieval location or secondary screening location after the personal item has been screened.
