Safety Route Guiding Device for Industrial Plant Evacuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial plant emergencies, such as chemical reactions or machine malfunctions, often complicate evacuation routes, leading to confusion and difficulty for operators in reaching safety zones, especially when instructions are complex and visibility is limited.
Innovation Solution
A method utilizing mobile terminals to receive alarm data, guide users from clearance zones to security zones by providing status updates on other affected users, and dynamically updating navigation instructions based on emergency conditions and user positions, allowing for efficient evacuation and tracking of personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users are provided with detailed navigation instructions during emergency evacuation, then the accuracy of route guidance is improved, but the complexity of information processing increases making it harder for panicked users to understand and follow
Solution Approach 1:
The navigation instructions are segmented into simple, discrete steps rather than presented as complex continuous directions. Each step is individually processed and displayed to the user, breaking down the overall evacuation route into manageable segments that can be easily understood and followed during panic conditions.
Solution Approach 2:
The mobile terminal acts as an intermediary between the safety route guiding device and the user. It receives complex navigation data from the guiding device and transforms it into simplified visual displays and audio instructions that are easy for panicked users to comprehend and follow.
2Ease of operation
If the evacuation route is made simple and direct, then the ease of operation is improved, but the time required to reach safety may increase due to complicated emergency conditions
Solution Approach 1:
The evacuation route is made dynamic rather than static. The safety route guiding device continuously monitors emergency conditions and user positions, automatically adjusting and updating navigation instructions in real-time. This allows the route to adapt to changing conditions while maintaining simplicity for the user.
Solution Approach 2:
The system implements feedback loops where the mobile terminal continuously reports user position and status back to the safety route guiding device. This feedback enables the system to monitor evacuation progress and dynamically adjust routing decisions to optimize both simplicity and time efficiency.
3Reliability
If the system tracks and monitors all users during evacuation, then the reliability of safety monitoring is improved, but the quantity of data processing and device complexity increase
Solution Approach 1:
The system extracts and processes only the most critical data elements needed for safety monitoring, such as user position, evacuation status, and emergency conditions. Non-essential data is filtered out or aggregated, reducing the overall data quantity while maintaining monitoring reliability.
Solution Approach 2:
The mobile terminal serves multiple functions simultaneously: it provides navigation instructions, tracks user position, monitors evacuation status, and communicates with the safety route guiding device. This multi-functionality reduces the need for separate dedicated systems, thereby reducing overall device complexity while maintaining comprehensive monitoring.
