Solution Overview

Problem

In environments with flat gate systems, such as office buildings and stations, security staff face challenges in identifying the location of unauthorized users or those needing assistance, as existing systems require the display unit to be in close proximity to the user, making it difficult for staff to recognize the location from a distance.

Innovation Solution

A person display control device and method that associates determination results with location information, recording this data in a database to enable displays that show the location of action-required persons from a separate location, using a system comprising read, sending, detection, determination, and display units to provide location-specific information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the display unit is provided in the floor unit where the user is standing to indicate the location of an unauthorized user, then the location can be indicated, but the staff cannot view the display from a distance

Engineering Contradiction:
Improvelocation informationVSAvoidviewability from distance
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

A communication device serves as an intermediary between the floor unit display and the staff member. The floor unit display provides location information to the communication device, which then transmits this information to a display unit located in a position where staff can easily view it, eliminating the need for staff to be physically close to the unauthorized user.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system transitions from a single-location display (floor unit where user stands) to a multi-dimensional information distribution system. Location information is captured at the floor unit level and then transmitted to multiple display locations including staff rooms and control centers, allowing staff to view information from various distances and positions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the display unit is provided apart from the unauthorized user such as in a station staff room, then staff can view the display from a distance, but the display cannot indicate the specific location of the unauthorized user

Engineering Contradiction:
Improveviewability from distanceVSAvoidlocation information
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The communication device acts as an intermediary that captures location information from the floor unit and preserves it while transmitting to remote display units. This ensures that even when displays are located in staff rooms or control centers away from the unauthorized user, the specific location information remains intact and is displayed with appropriate contextual details.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system segments the display function into multiple components: the floor unit display for immediate local indication, the communication device for information transmission, and remote display units for staff viewing. Each segment handles specific aspects of location information, ensuring both distance viewability and location specificity are maintained.

Inventive Principle:
Principle #1Segmentation

AI summary

A determination unit (6) determines whether a user having entered an authentication area (102) provided on a floor surface is an action-required person. A management unit (12) associates a determination result with respect to an action-required person produced by the determination unit (6) with location information of the user, and records resultant data in a person information database (13). A display control unit (14) controls a display unit (15) to display an image showing a location of an action-required person using the person information database (13).
