Solution Overview

Problem

Existing fire safety systems often fail to quickly and reliably guide evacuees to the safest evacuation routes during a fire, leading to potential loss of life and significant economic damage.

Innovation Solution

A system comprising sensing units that detect fire, a graph generation server to define vertices and edges, and a network to transmit shortest evacuation route information using Dijkstra and A* algorithms to generate reliable evacuation paths, with guide lights indicating the safest routes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing fire safety systems are used, then fire detection is possible, but evacuation route guidance is slow and unreliable

Engineering Contradiction:

Improveevacuation route guidance reliabilityVSAvoidevacuation route guidance time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system pre-calculates and stores multiple possible evacuation routes in advance, so that when a fire is detected, the evacuation route information can be immediately transmitted to sensing units without delay for route calculation, significantly reducing response time

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically updates evacuation route information based on real-time fire detection signals from multiple sensing units, allowing the evacuation paths to be adjusted as fire conditions change, improving both speed and reliability of evacuation guidance

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If evacuation route information is transmitted to all sensing units, then comprehensive coverage is achieved, but system complexity increases

Engineering Contradiction:

Improveevacuation coverageVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system divides the building into multiple zones with dedicated sensing units, and transmits evacuation route information to only the sensing units relevant to the detected fire location, rather than broadcasting to all units, reducing communication overhead and system complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system generates and transmits evacuation route information tailored to specific local areas where fires are detected, allowing each sensing unit to receive only the evacuation information relevant to its location, improving efficiency and reducing unnecessary system complexity

Inventive Principle:

Principle #3Local quality
