Solution Overview

Problem

Current mustering systems in buildings face challenges such as reliance on static muster points, hardware dependency, limited redundancy, inability to track un-badged individuals, and lack of communication for status updates during emergencies, which can hinder effective evacuation processes.

Innovation Solution

A portable computing device-based mustering system that allows users to register and communicate their safety status, self-identify as mayors, and dynamically update muster points, using smartphones or tablets to share location and situational information, enabling dynamic muster points and real-time communication among users and first responders.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If static muster points are used, then system simplicity is maintained, but adaptability to changing emergency conditions deteriorates

Engineering Contradiction:
Improveadaptability to changing emergency conditionsVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent transforms static muster points into dynamic muster points that can change location based on real-time environmental conditions. The mobile computing device allows mayors to dynamically update muster point locations, and the system automatically adjusts evacuation routes based on sensor data about fire, smoke, and hazardous conditions. This dynamic adaptation resolves the contradiction by enabling the system to respond to changing emergency conditions while maintaining operational simplicity through automated decision-making algorithms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements continuous feedback loops where sensor data from the building environment is constantly monitored and fed back to update muster point locations and evacuation routes. The mobile computing device receives real-time information about environmental conditions and automatically adjusts muster point assignments, creating a closed-loop control system that adapts to changing conditions without requiring complex manual intervention.

Inventive Principle:
Principle #23Feedback

2Reliability

If hardware-based tracking systems are used, then reliability of tracking is improved, but device complexity and cost increase

Engineering Contradiction:
Improvetracking reliabilityVSAvoidhardware dependency
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces physical hardware tracking systems with a software-based solution that uses the existing mobile computing devices already possessed by building occupants. Instead of requiring specialized hardware badges or trackers, the system creates a virtual copy of the tracking functionality through mobile applications that leverage cameras, sensors, and communication capabilities of standard smartphones and tablets, thereby maintaining tracking reliability while eliminating hardware dependency.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The mobile computing device serves multiple functions: it acts as a personal tracker, communication device, muster point indicator, and emergency information portal. By making the mobile device universal and multi-functional, the system eliminates the need for dedicated hardware components, reducing overall system complexity while maintaining or enhancing tracking reliability through the device's existing sensors and processing capabilities.

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

3Productivity

If centralized control systems are used, then coordination efficiency is improved, but loss of information during system failures increases

Engineering Contradiction:
Improvecoordination efficiencyVSAvoidinformation loss during failures
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent segments the centralized control system into distributed autonomous units where each mobile computing device operates as an independent node. Mayors have autonomous authority to make decisions and update muster points locally, while the system maintains coordination through peer-to-peer communication. This segmentation ensures that if one node fails, others continue to function independently, preventing total system collapse and information loss while maintaining coordination efficiency through distributed consensus mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements redundancy by allowing multiple mayors to be designated and by enabling any mayor to update muster points independently. This creates a cushion against information loss by ensuring that critical evacuation information is replicated across multiple nodes before any failure occurs. The distributed architecture ensures that no single point of failure can completely disrupt the system, as other nodes contain redundant information and can continue coordinating evacuations.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

4Productivity

If manual mustering processes are used, then ease of operation is maintained, but productivity of evacuation process deteriorates

Engineering Contradiction:
Improveevacuation efficiencyVSAvoidoperational simplicity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system enables self-service by allowing occupants to automatically receive personalized evacuation instructions and muster point assignments based on their location and the current emergency situation. The mobile computing device automatically processes registration information, calculates optimal routes, and updates muster points without requiring manual intervention from mayors for each individual. This automation dramatically improves evacuation productivity while maintaining ease of operation through intuitive interfaces that require minimal user input.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical processes of mustering with automated electronic systems. Instead of manual roll calls, paper-based tracking, and physical direction-giving, the system uses mobile computing devices with automated algorithms to track occupants, calculate routes, and communicate instructions. This substitution of mechanical processes with electronic automation significantly increases evacuation productivity while maintaining simplicity through user-friendly interfaces that present information in an easily consumable format.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
