Interlock Body Scanning With Separation Sensing for Faster Security Checks

Solution Overview

Problem

Existing security interlocks at facilities like airports and train stations face challenges in efficiently controlling the flow of people and conducting security checks, leading to delays and high personnel costs while maintaining high security reliability.

Innovation Solution

An interlock system equipped with a body scanner and a separation sensor that measures the number of people in the inner region, allowing for automated and secure security checks without the need for constant security personnel, thereby reducing delays and personnel costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If security personnel are deployed to manually guide people and monitor the interlock region, then security reliability is improved, but personnel costs and time delays increase

Engineering Contradiction:

Improvesecurity reliabilityVSAvoidtime delays

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system uses automated sensors and body scanners to perform security checks without human intervention. The separation sensor automatically detects the number of people in the interlock region, and the body scanner automatically scans individuals, eliminating the need for security personnel to manually guide or monitor each person while maintaining high security reliability.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual security personnel with an automated system consisting of separation sensors and body scanners. This mechanical-to-automated substitution eliminates human labor requirements while providing continuous, consistent security monitoring without the time delays associated with manual checks.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If security personnel are deployed to manually guide people and monitor the interlock region, then security reliability is improved, but personnel costs increase

Engineering Contradiction:

Improvesecurity reliabilityVSAvoidpersonnel costs

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The system uses automated sensors and body scanners to perform security checks without human intervention. The separation sensor automatically detects the number of people in the interlock region, and the body scanner automatically scans individuals, eliminating the need for security personnel to manually guide or monitor each person while maintaining high security reliability.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual security personnel with an automated system consisting of separation sensors and body scanners. This mechanical-to-automated substitution eliminates human labor requirements while providing continuous, consistent security monitoring without the time delays associated with manual checks.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If the body scanner scans each individual person, then security detection accuracy is improved, but processing time increases

Engineering Contradiction:

Improvesecurity detection accuracyVSAvoidprocessing speed

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The separation sensor performs preliminary detection by automatically identifying and counting individuals in the interlock region before the body scanner operates. This preliminary action ensures that only one person is present and properly positioned, allowing the body scanner to efficiently scan a single individual without repeated attempts or delays from multiple people being present.

Inventive Principle:

Principle #10Preliminary action
