Solution Overview

Problem

It is difficult for external visitors, such as delivery persons, to locate and reach the correct seat or desk position within a large organization like a company due to the large number of people present, posing a challenge in ensuring secure navigation to the visit destination.

Innovation Solution

A visit assistance apparatus that registers a visitor's face image and associated visit assistance information, performs face authentication, specifies the user's identification and seat position based on floor information, and generates guide information for navigation to the specified seat.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If face authentication is performed to ensure security, then security is improved, but the time required for visitor registration and authentication increases

Engineering Contradiction:
ImprovesecurityVSAvoidauthentication time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs face image registration in advance before the visitor actually visits. The registration unit stores the visitor's face image and associates it with visit assistance information (such as the seat position of the person to be visited). When the visitor arrives, the pre-registered face image is quickly retrieved and compared with the captured face image, eliminating the need for time-consuming registration at the moment of visit while maintaining secure authentication.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If manual guidance methods are used, then ease of operation is improved, but productivity and efficiency of visitor management deteriorates

Engineering Contradiction:
Improveguidance easeVSAvoidvisitor management efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The system enables automatic visitor guidance without requiring manual intervention from security personnel. When face authentication is successful, the specification unit automatically specifies the seat position of the person to be visited based on the associated visit assistance information. The generation unit then automatically generates and provides guide information (such as direction and distance to the seat) to the visitor. This self-service automation eliminates manual guidance tasks while improving visitor management efficiency.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If detailed visit assistance information is collected, then ease of operation for guidance is improved, but device complexity increases

Engineering Contradiction:
Improveguidance accuracyVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system uses a multi-functional face image registration and authentication apparatus that performs multiple functions: face image registration, visit assistance information association, face authentication, seat position specification, and guide information generation. By consolidating these functions into a single apparatus, the system achieves detailed and accurate visitor guidance without proportionally increasing overall system complexity. The apparatus serves as a universal solution handling all visitor guidance tasks through integrated functionality.

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

AI summary

A visit assistance apparatus includes: a registration unit configured to register a face image of a visitor and visit assistance information in which identification information of a visitor is associated with identification information of a user to be visited; an authentication control unit configured to cause face authentication to be performed by comparing the face image of the visitor captured by a camera installed in an entry control apparatus that restricts an entry to a floor with the registered face image of the visitor; a specification unit configured to specify, when the face authentication has been successful, identification information of the user based on the visit assistance information, and specify a seat position of the specified user based on floor information; and a generation unit configured to generate guide information for guiding the visitor to the specified seat position of the user on the floor.
