Solution Overview

Problem

Current security screening processes are labor-intensive, time-consuming, and prone to inaccuracies due to the reliance on human operators, leading to potential security threats being missed, especially with the increasing volume of international travel and varying border security standards.

Innovation Solution

Implementing a dual-phase security screening system that includes an initial screening using available data and parameters, followed by a supplemental screening with additional data and parameters, leveraging advanced computerized techniques such as deep learning and machine learning to enhance accuracy and throughput, and automate the identification of security threats.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If human operators manually screen objects at security checkpoints, then security threats can be detected through expert judgment, but the process becomes labor-intensive and time-consuming with increasing travel volume

Engineering Contradiction:
Improvesecurity threat detection accuracyVSAvoidscreening throughput
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent segments the security screening process into distinct phases: initial automated screening using machine learning models, intermediate flagging of suspicious items, and final manual verification only for flagged cases. This segmentation allows the system to leverage automated processing for clear cases (high throughput) while maintaining human expertise for ambiguous cases (high reliability).

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent replaces the mechanical system of manual visual inspection with an automated computer vision system using deep learning neural networks. The system automatically analyzes images from X-ray scanners and other detection devices, substituting human operators for routine screening tasks while maintaining threat detection capability through trained algorithms.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If more human screeners are deployed to handle increased travel volume, then screening throughput increases, but labor costs and operational complexity increase

Engineering Contradiction:
Improvescreening throughputVSAvoidoperational complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements a self-service automated screening system that operates independently of human operators for the majority of cases. The machine learning models automatically process images, identify potential threats, and make screening decisions without requiring human intervention, thereby increasing throughput without proportional increases in operational complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent changes the operational parameters from manual inspection metrics (operator fatigue, response time) to automated system parameters (processing speed, algorithm accuracy). The system can dynamically adjust sensitivity thresholds and processing priorities based on threat levels and traffic volume, optimizing throughput without linearly increasing operational complexity.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If manual inspection is performed on all flagged baggage, then security accuracy is maintained, but the screening process becomes excessively time-consuming

Engineering Contradiction:
Improvesecurity screening accuracyVSAvoidscreening time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies partial manual inspection only to the subset of baggage that is flagged by the automated system, rather than inspecting all baggage manually. This partial action approach maintains security accuracy for potential threats while avoiding the time loss associated with universal manual inspection of all items.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent implements a feedback loop where the automated screening system continuously learns from manual inspection outcomes and false positive/negative data. This feedback mechanism improves the accuracy of automated flagging over time, reducing the number of items requiring manual inspection and thereby reducing overall screening time while maintaining or improving accuracy.

Inventive Principle:
Principle #23Feedback

4Adaptability or versatility

If different security standards are applied at different international borders, then local security requirements are met, but consistency and efficiency across multiple checkpoints deteriorate

Engineering Contradiction:
Improvecompliance with local security standardsVSAvoidmulti-checkpoint screening efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent designs a universal automated screening system with configurable parameters that can adapt to different security standards at various international borders. The same core machine learning infrastructure serves multiple jurisdictions by loading different threat profiles, sensitivity thresholds, and detection priorities, thereby maintaining local compliance while preserving operational efficiency across checkpoints.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

In an example, a computing device comprises at least one processor, a memory, and a non-transitory computer-readable storage medium storing instructions thereon that, when executed, cause the at least one processor to perform functions comprising: performing an initial security screening on an object based on a first set of security-related data associated with the object and a first set of security screening parameters, and performing a supplemental security screening on the object based on a second set of security-related data associated with the object and a second set of security screening parameters. The first set of security-related data may be different from the second set of security-related data, and the first set of security screening parameters may be different from the second set of security screening parameters.
