Solution Overview
Problem
Current nonintrusive vehicle inspection systems face challenges such as operator radiation exposure, complex operation, heavy weight, and limited transportation capabilities, leading to inefficiencies in scanning capacity and increased waiting times at high-security zones like harbors and border crossings.
Innovation Solution
A mobile scanning system with an automated control unit outside the radiation exclusion area, capable of rapid transportation in ISO containers, and a drive-through scanning process that minimizes operator exposure and allows for high-capacity scanning (up to 200 vehicles per hour) using a low-intensity radiation source and advanced detector technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operators work inside the control cabin mounted on the scanner chassis, then they can directly control the scanning process, but they are exposed to professional radiation risks
Solution Approach 1:
A robotic arm serves as an intermediary between the operator and the scanning equipment. The operator controls the scanning process remotely through the robotic arm's automated systems, eliminating the need for operators to be physically present in the radiation zone while maintaining full control capability over the inspection process
Solution Approach 2:
The patent replaces the traditional mechanical control system where operators manually operate controls inside the scanner with an automated robotic control system. The robotic arm executes scanning operations autonomously based on remote commands, substituting human presence in the radiation zone with an automated mechanical system
2Reliability
If mobile scanning systems use heavy chassis to support scanning equipment, then they can perform scanning operations, but they become difficult to transport and require specialized vehicles
Solution Approach 1:
The scanning system is segmented into modular components that can be independently transported and assembled. Instead of using a single heavy chassis, the system uses standardized container units that can be transported by various modes of transport and quickly deployed at inspection locations
Solution Approach 2:
The system transitions from a static heavy chassis design to a dynamic modular container system that can be easily repositioned. The standardized containers can be quickly loaded onto different vehicles and deployed at various locations, providing flexibility and ease of transport while maintaining full scanning capability
3Reliability
If scanning systems require multiple personnel including drivers and data operators, then they can operate reliably, but they increase operational complexity and time consumption
Solution Approach 1:
The robotic arm system is designed to be self-sufficient and autonomous during scanning operations. It automatically performs inspection tasks, processes data, and communicates results without requiring continuous human intervention. The system manages its own operations, reducing the need for multiple specialized personnel while maintaining reliable scanning functionality
4Reliability
If conventional scanning systems are used at high-security zones, then security inspections can be performed, but waiting times increase due to limited scanning capacity
Solution Approach 1:
The robotic arm system enables continuous scanning operations without interruption. It can rapidly inspect vehicles in sequence, maintaining constant operational flow to maximize scanning capacity. The automated system continuously processes inspections without the delays associated with manual operations, reducing waiting times while maintaining thorough security screening

Function Achieved in This Case
The system significantly reduces operator radiation risk, simplifies operation, enables rapid transportation, and increases scanning capacity, ensuring high-security inspections can be conducted efficiently and effectively, even in high-demand locations like busy harbors and border crossings.
Implementation Method 1
The nonintrusive inspection system principle implies the irradiation of a row of detectors linearly placed in front of a beam of penetrating radiation
Implementation Method 2
The electrical signals emitted by the detectors are processed analogically/digitally with the purpose of generating, line by line, a radiography

AI summary
The present invention consists of a method and a scanning system for the nonintrusive inspection of vehicles, container trucks and train carriages, realized without direct human intervention upon the inspected object, thus eliminating time wasting activities like physical control, unsealing, etc. The proposed method for nonintrusive inspection of vehicles and containers has a high inspection capacity (up to 200 vehicles per hour), by achieving a complete vehicle radiography (except the driver's cabin), while driving through a scanning portal, geometrically optimized to be transported rapidly in ISO standardized containers using conventional transport systems (airplane, ship, train, or terrestrial on public roads). The system which implements the method presented earlier is constituted from a mobile scanning unit and a mobile control center which is positioned outside the exclusion area “a” which remotely command all the processes involved in the nonintrusive inspection.
