Solution Overview

Problem

Existing technologies struggle to quickly and effectively address localized congestion in event venues such as stadiums and facilities like restrooms and shops, leading to decreased visitor satisfaction due to prolonged congestion.

Innovation Solution

A server device with a calculation unit to determine congestion levels and an instruction unit to alert staff when congestion occurs, enabling immediate resolution by staff members.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If visualization of congestion state is implemented using monitoring cameras, then congestion state can be grasped, but congestion cannot be quickly resolved due to lack of automated notification and response mechanism

Engineering Contradiction:
Improvecongestion state informationVSAvoidcongestion resolution speed
Core Design Contradiction:
Loss of informationVSProductivity

Solution Approach 1:

The system implements automated feedback by notifying staff members when congestion is detected in a facility. The notification is sent to a terminal device associated with the staff member, creating a closed-loop system where congestion detection automatically triggers a response action, eliminating the need for manual monitoring and enabling quick resolution.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If manual monitoring of facilities is used, then congestion can be detected, but response time is delayed and visitor satisfaction decreases

Engineering Contradiction:
Improvecongestion detection accuracyVSAvoidresponse time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary action by automatically notifying staff members before congestion becomes severe. The notification is sent in advance when congestion is first detected, allowing staff to take preventive or early corrective actions, thereby reducing response time and maintaining visitor satisfaction.

Inventive Principle:
Principle #10Preliminary action

3Loss of information

If comprehensive monitoring of all facilities is implemented, then congestion state can be grasped, but system complexity increases

Engineering Contradiction:
Improvefacility congestion informationVSAvoidmonitoring system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system extracts only the essential information needed for congestion management by notifying staff members directly about specific congested facilities. Instead of providing comprehensive data about all facilities, the system extracts and delivers only the critical notification information, simplifying the overall system while maintaining effective monitoring.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A server device (100) that contributes to resolving congestion in an event venue or the like is provided. The server device (100) includes a calculation unit (101) and an instruction unit (102). The calculation unit (101) calculates a degree of congestion of a monitored facility which is a facility to be monitored for a congestion state. The instruction unit (102) determines, based on the degree of congestion of the monitored facility, whether or not the monitored facility is congested. When the monitored facility is congested, the instruction unit (102) instructs a staff member in a venue including the monitored facility to resolve the congestion of the congested monitored facility.
