Train Evacuation Guidance System with Dynamic Light Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passengers in trains face difficulties in identifying the evacuation route to a safe place due to limited visibility in tunnels and varying exit directions, leading to inefficiencies and potential misjudgments during emergencies.
Innovation Solution
A passenger evacuation direction guidance system that includes an evacuation direction generation unit and a display unit with light-emitting and voice-output capabilities, which detects objects on the train's periphery to provide clear and directional guidance through adjustable indicators, ensuring passengers can exit safely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If emergency exit guide lamps are installed in the tunnel to guide passengers to a safe place, then passengers can see the guide lamps, but passengers cannot recognize the direction to the emergency exit from their current positions and cannot efficiently evacuate
Solution Approach 1:
The evacuation guidance system is segmented into multiple functional modules: guide light emitting units installed at different locations (tunnel ceiling, wall surfaces, emergency exit doors) that work together to provide comprehensive directional information. This segmentation allows the system to overcome the limitation of single-point guidance by distributing information sources throughout the evacuation path.
Solution Approach 2:
The patent introduces intermediary elements such as reflective materials on wall surfaces and ceiling, and intermediate guide lights that relay directional information from the source to the passenger. These intermediaries amplify and distribute the guidance signal, ensuring passengers can always see the direction to the nearest emergency exit regardless of their position in the tunnel.
2Ease of operation
If guide light is used to indicate evacuation direction, then passengers can see the guide, but the structure of the train limits the effectiveness as evacuation directions vary by door location and disaster occurrence point
Solution Approach 1:
The guide light emitting units are designed to dynamically adjust their operation based on the disaster occurrence point and the nearest emergency exit location. The system activates specific guide lights corresponding to the relevant evacuation route, ensuring that the guidance information is always current and accurate for the specific emergency situation.
Solution Approach 2:
Different guide light emitting units are positioned at specific locations (ceiling, walls, door areas) to provide localized guidance information appropriate to each zone. This allows passengers at different positions and exiting through different doors to receive directionally accurate guidance tailored to their specific location and evacuation route.
3Illumination intensity
If emergency exit guide lamps are installed in the tunnel, then passengers can see the lamps, but passengers suffer from difficulty in finding the emergency exit guide lamps in an urgent situation
Solution Approach 1:
Guide light emitting units are pre-installed at all potential evacuation points including emergency exit doors and along the tunnel path before any emergency occurs. This preliminary placement ensures that when an emergency happens, passengers immediately see the pre-positioned guidance lights indicating the direction to the nearest exit, eliminating the need to search for guidance in the panic of the moment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system efficiently directs passengers to safe exits by providing clear, multi-directional guidance, reducing confusion and enhancing safety during emergencies, even in low-light conditions.
Implementation Method 1
an evacuation direction indicating module which is installed on the train so as to be moved together with the train and indicates the passenger evacuation direction on the object by emitting light toward the object
