Incident-Modality Access Control for Occupant Reunification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems in buildings, such as smart buildings, fail to effectively manage access points during incidents, leading to inefficiencies in evacuating and reunifying occupants based on the nature of the incident.
Innovation Solution
A computing device that determines the modality of an incident, such as active, false, or preventive, and adjusts access point control and reunification routes accordingly, using sensors, communication devices, and third-party data to guide occupants to safety and reunite them with designated persons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access points are electronically controlled by a central computing device, then security and control are improved, but the system cannot effectively manage access during different incident types
Solution Approach 1:
The access control system dynamically adjusts its behavior based on incident modality. The computing device receives incident data, determines the modality (active, false, preventive), and automatically modifies access point control parameters accordingly. This dynamic adaptation allows the same system to handle multiple incident types effectively without manual reconfiguration.
Solution Approach 2:
The system changes operational parameters of access points based on incident type. For active incidents, access points may be locked or restricted; for false incidents, normal access is maintained; for preventive incidents, selective access control is applied. These parameter changes enable the system to maintain reliability across different incident scenarios.
2Productivity
If access control is centralized, then control efficiency is improved, but the system lacks the capability to dynamically adjust to different incident modalities
Solution Approach 1:
The system implements a feedback loop where incident data is continuously received and analyzed. The computing device determines incident modality based on received data and adjusts access control settings in real-time. This feedback mechanism enables centralized control to adapt dynamically to different incident modalities, improving both evacuation efficiency and system versatility.
Solution Approach 2:
The system prepares multiple access control configurations in advance for different incident modalities. When an incident is detected, the appropriate pre-configured settings are automatically applied, enabling rapid response without delay for manual configuration. This preliminary preparation enhances productivity during evacuations.
3Device complexity
If access points are controlled without considering incident type, then system simplicity is maintained, but evacuation and reunification efficiency deteriorates
Solution Approach 1:
The access control system is designed with multi-functionality to handle various incident modalities through a single unified platform. The computing device performs multiple functions: receiving incident data, determining modality, selecting appropriate control strategies, and managing access points. This universal approach maintains system simplicity while improving reunification efficiency through intelligent incident-type-specific responses.

AI summary
A device, system, and method for electronic access control to reunify persons is provided. A device determines, using electronic data, a modality of an incident associated with a premises. The device determines: one or more routes associated with the premises and the modality; and electronic reunification data associated with the modality, the electronic reunification data defining one or more first persons and one or more second persons that are to meet in association with the incident and in accordance with the one or more routes. The device controls access points at the premises, along the one or more routes, to one or more of unlock, lock, open, or close. The device transmits one or more notifications to one or more communication devices, indicative of the electronic reunification data.
