Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current emergency guidance systems in buildings are limited in dynamically adjusting escape routes and communicating rescue situations, leading to potential increased casualties due to fixed installations that cannot adapt to changing emergency conditions.
Innovation Solution
An evacuation guidance device featuring a bendable linear illuminator with a bobbin unit that winds and unwinds to indicate position and distance, and a communication unit using luminescence states for bidirectional communication between rescue agents and commanders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed emergency guide light or sign is installed, then the escape route can be indicated, but it cannot adapt to changing emergency situations such as closed emergency doors or fire around the exit
Solution Approach 1:
The patent applies dynamics by making the guidance device portable and movable rather than fixed. The rescue agent can carry the device and reposition it to different locations based on the evolving emergency situation, allowing the escape route indication to dynamically adapt to changing conditions such as blocked exits or new hazards.
Solution Approach 2:
The linear illuminator serves as an intermediary between the rescue agent and the evacuees. It provides visual guidance that can be extended or repositioned as needed, mediating the communication of escape route information without requiring complex electronic displays or fixed installations.
2Loss of information
If a portable linear emergency guidance device is used, then the escape route can be changed according to field situation, but it is difficult to determine the distance of the escape route and communicate with rescue agents
Solution Approach 1:
The patent applies color changes by using different colors of light emitted by the linear illuminator to indicate different distances or segments of the escape route. This provides intuitive visual information about distance without requiring complex measurement devices or electronic displays, maintaining simplicity while conveying critical distance information.
3Adaptability or versatility
If a fixed emergency guide light is installed, then the device structure is simple, but it cannot provide bidirectional communication between rescue agents and commanders
Solution Approach 1:
The patent applies universality by designing the device to perform multiple functions: providing visual escape route guidance, indicating distance information through color changes, and enabling bidirectional communication between rescue agents and commanders. This multi-functionality is achieved without significantly increasing device complexity, as the communication likely uses simple visual or audible signals integrated into the existing device architecture.

AI summary
The present disclosure relates to an evacuation guidance device for rescue, and more particularly, to an evacuation guidance device for rescue, which is capable of securing an evacuation route through a linear illuminator to guide an evacuee to a safety zone and bidirectionally communicating with a rescue agent to evaluate a rescue situation, when an emergency situation occurs in a building due to fire, power failure, a gas leakage, and the like. In the evacuation guidance device for rescue according to the present disclosure, a position of the bobbin unit may be identified through the first and second position notifying luminescence members so that there is an advantage in which position determination of the evacuee or the rescue agent may be easy.
