Solution Overview

Problem

The existing gate apparatuses face challenges in allowing users to pass through quickly due to difficulties in face authentication when a passport is placed on a reader in front of a face authentication device.

Innovation Solution

The gate apparatus includes biometrics information acquisition units to capture biometric data from users approaching or stopping in front of an exit gate door, with door control units that open the gate based on biometric comparisons, accommodating various user orientations and conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a face authentication device captures the face of a subject who placed a passport on a passport reader, then biometric authentication can be performed, but the subject cannot pass through the gate apparatus in a short time

Engineering Contradiction:
Improvebiometric authentication accuracyVSAvoidtime required for user to pass through
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs face capture and biometric comparison in advance while the user is still approaching the gate door, before the user needs to stop and place the passport. This preliminary action allows the authentication process to be completed or nearly completed before the user reaches the critical stopping point, thereby reducing the overall time required for passage while maintaining authentication reliability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The gate apparatus continuously captures face images of approaching users and continuously performs biometric comparisons with registered information, rather than waiting for the user to stop. This continuous operation eliminates idle time and ensures that authentication is always ready to proceed immediately when the user places the passport, enabling faster passage while maintaining accurate authentication.

Inventive Principle:
Principle #20Continuity of useful action

2Measurement precision

If the gate apparatus requires the user to stop in front of the door for face capture, then accurate biometric data can be obtained, but the passage efficiency is reduced

Engineering Contradiction:
Improvebiometric data qualityVSAvoidpassage efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The system transitions from a static face capture approach (requiring the user to stop) to a dynamic approach that can capture and process face images while the user is moving. The apparatus adapts its capture and comparison operations to the user's motion state, performing preliminary captures during approach and final confirmation when stopped, thereby maintaining data quality while improving passage efficiency.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs preliminary face captures and comparisons during the user's approach phase, gathering biometric data before the user needs to stop. This preliminary action reduces the amount of processing needed after the user stops, allowing for faster authentication while maintaining accurate biometric data collection through multiple capture opportunities during the approach.

Inventive Principle:
Principle #10Preliminary action

AI summary

A gate apparatus includes: an exit gate door; a first biometrics information acquisition unit that acquires, from a user who moves toward the exit gate door in a closed state, first target biometrics information to be compared with registered biometrics information registered in advance; a second biometrics information acquisition unit that acquires second target biometrics information to be compared with the registered biometrics information from the use who stops in front of the exit gate door when there is no matching in a comparison between the first target biometrics information and the registered biometrics information or the comparison is unable to be performed; and a door control unit that opens the closed exit gate door in accordance with a result of a comparison between the first target biometrics information or the second target biometrics information and the registered biometrics information.
