Solution Overview
Problem
Existing evacuation route guidance systems fail to provide real-time, passable routes during disasters as they rely on static hazard maps and cannot adapt to changing conditions, leading to potential hazards like flooded areas or impassable roads.
Innovation Solution
An evacuation route guidance system that uses cameras to analyze movement and create dynamic routes avoiding dangerous areas, outputting safe paths to display devices, incorporating hazard maps and movement analysis to adapt to changing disaster scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static hazard maps are used for evacuation route guidance, then the system is simple to implement, but the routes may not be passable as disaster conditions change in real-time
Solution Approach 1:
The patent transforms the static hazard map into a dynamic system by continuously updating route information based on real-time disaster conditions. The system dynamically adjusts evacuation routes by monitoring changes in hazard levels and recalculating safe paths, ensuring routes remain passable despite evolving disaster situations.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring disaster conditions and using this information to update evacuation routes. Sensors and data sources provide real-time feedback on hazard levels, which the system processes to adjust route recommendations, creating a closed-loop system that adapts to changing conditions.
2Measurement precision
If real-time camera monitoring and movement analysis are added to analyze moving body movement, then the accuracy of route creation is improved, but the device complexity and processing requirements increase
Solution Approach 1:
The patent introduces an intermediary processing layer that bridges camera data capture and route creation. This intermediary layer pre-processes camera images to extract movement patterns and characteristics, then feeds this processed information to the route creation algorithm, reducing the computational burden while maintaining analysis accuracy.
Solution Approach 2:
The system performs preliminary analysis of moving body patterns before final route creation. By pre-processing camera data to identify movement trends and characteristics in advance, the system prepares optimized input for the route generation algorithm, improving efficiency and reducing real-time processing requirements.
3Adaptability or versatility
If evacuation routes are created based on hazard maps alone, then the system is easy to operate, but it cannot adapt to changing disaster conditions like receding water or new obstacles
Solution Approach 1:
The system implements self-service by automatically detecting changes in disaster conditions and adjusting evacuation routes without requiring manual intervention. The system autonomously monitors hazard levels, analyzes moving body movements, and recalculates routes based on current conditions, maintaining ease of operation while achieving high adaptability.
Solution Approach 2:
The patent replaces manual route planning with an automated computational system. Instead of relying on static pre-planned routes or manual assessment, the system uses algorithms to automatically generate and update evacuation routes based on real-time data from hazard maps, cameras, and sensors, achieving both adaptability and operational simplicity.
