Evacuation Task Management System Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing evacuation assistance systems face challenges in coordinating emergency evacuations in buildings with multiple assets, as they require transmitting extensive building floor plans and asset lists, consuming significant processing power and bandwidth, and necessitating substantial power and processing power for data display and parsing at edge devices.
Innovation Solution
A computing device system that transmits only initial building and asset data needed by each edge device, monitoring compliance with initial instructions to determine if additional data is required, thereby reducing bandwidth and processing power consumption, and directing users through evacuation paths efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If entire sets of building floor plans and asset lists are transmitted from the database to edge devices, then complete evacuation information is available at edge devices, but substantial processing power and bandwidth are consumed at both database and edge devices
Solution Approach 1:
The patent extracts and transmits only the specific evacuation instructions and relevant asset data needed by each responder to their edge device, rather than transmitting entire building floor plans and complete asset lists. This selective data extraction reduces bandwidth consumption and processing requirements while providing sufficient information for evacuation tasks.
Solution Approach 2:
The patent segments the evacuation data into specific tasks and assigns them to individual responders. Each edge device receives only the segment of data relevant to its assigned evacuation responsibilities, reducing overall system bandwidth consumption and processing requirements while maintaining complete coverage of the evacuation scenario.
2Adaptability or versatility
If edge devices receive and process complete building data sets, then comprehensive evacuation planning is enabled, but power and processing power consumption increase significantly
Solution Approach 1:
The system extracts only the necessary evacuation instructions and asset data for each specific responder task, transmitting minimal data to edge devices. This maintains comprehensive evacuation planning capability across the system while significantly reducing the processing and power requirements at individual edge devices.
Solution Approach 2:
The patent implements partial data transmission where edge devices receive only the portion of building data necessary for their specific evacuation assignments rather than complete datasets. This partial action approach maintains system-wide adaptability while reducing local power and processing demands.
3Reliability
If extensive building floor plans and asset lists are transmitted to multiple edge devices, then complete evacuation coverage is achieved, but bandwidth consumption increases substantially
Solution Approach 1:
The patent segments evacuation data and assignments by responder and task, transmitting only the necessary data segments to each edge device. This segmentation approach ensures complete evacuation coverage across all responders while minimizing total bandwidth consumption through selective data distribution.
Solution Approach 2:
The system extracts and transmits only the specific evacuation instructions and asset data relevant to each responder's assigned tasks, rather than transmitting complete building floor plans and asset lists to all devices. This extraction approach maintains reliable evacuation coverage while substantially reducing bandwidth consumption.
