Rescue Capsule Airflow and Visibility for IDLH Evacuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In rescue situations involving immediately dangerous to life or health (IDLH) environments, victims often become unconscious due to poor air quality and thermal insults, necessitating a system to supply fresh air and expel hazardous air while protecting against additional thermal injuries and debris during removal.
Innovation Solution
A rescue system comprising a capsule with a wall that includes phosphors and reflectors for visibility, an air bladder for cushioning and air supply, one-way air flow vents for hazardous air expulsion, and structural components for safe transport, allowing for the safe and efficient removal of victims.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a capsule is used to protect victims during rescue, then protection from thermal injuries and debris is improved, but visibility in dark environments deteriorates
Solution Approach 1:
The capsule incorporates phosphors that absorb ultraviolet light and emit visible light, causing the capsule to glow and become visible in dark environments. This resolves the visibility problem while maintaining the protective enclosure.
Solution Approach 2:
Phosphor materials serve as an intermediary between ultraviolet light sources and the human eye, converting invisible UV radiation into visible glow that enhances capsule visibility without compromising protection.
2Object-affected harmful factors
If air supply systems are added to provide fresh air to victims, then air quality for unconscious victims is improved, but device complexity increases
Solution Approach 1:
The air supply system combines the air bladder, one-way air flow vents, and rescue air bottle into an integrated assembly that works together to provide fresh air while automatically managing airflow direction, reducing overall system complexity.
Solution Approach 2:
The one-way air flow vents automatically control airflow direction without external control mechanisms, allowing the system to self-regulate fresh air intake and hazardous air expulsion based on pressure differentials.
3Duration of action of stationary object
If multiple ventilation mechanisms are implemented for fresh air supply and hazardous air expulsion, then air quality sustainability is improved, but device complexity increases
Solution Approach 1:
The ventilation system ensures continuous fresh air supply and continuous hazardous air expulsion through the air bladder and one-way vents, maintaining sustainable air quality throughout the rescue operation without interruption.
Solution Approach 2:
The ventilation function is divided into separate components: fresh air intake through the air bladder and hazardous air expulsion through one-way vents, allowing each component to specialize in one function while working together as a system.
4Strength
If structural support components are added to the capsule wall, then capsule structural integrity is improved, but manufacturing complexity increases
Solution Approach 1:
The capsule wall combines webbing material with integrated structural support elements to create a composite structure that provides high strength and durability while maintaining manufacturability through standardized components.
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 provides a sustainable environment for rapid rescue by ensuring fresh air supply and hazardous air expulsion, while protecting victims from further injuries and obstacles, facilitating easy handling and visibility in dark environments.
Implementation Method 1
At least a portion of the capsule wall may comprise phosphors that may absorb energy such as light from an external source. Upon absorbing energy and thereby becoming energized, the phosphors may emit visible light and thereby 'glow' to make the capsule wall easier to see.
Implementation Method 2
at least a portion of the capsule wall may comprise reflectors that reflect visible light to make the capsule wall easier to see
Implementation Method 3
The one-way air flow vents may allow air to flow in one direction so that hazardous air is exhaled from the victim and then expelled from the capsule.

AI summary
Embodiments of the present invention may comprise a rescue system and/or rescue device. A capsule may have a capsule wall that defines an inner capsule area into which a victim may be configured. A rescue air bottle may supply fresh air to the victim by first inflating an air bladder and then supplying the fresh air from the air bladder to the victim. The victim may inhale the fresh air. The hazardous air may be expelled from the capsule via one or more one-way air flow vents via positive pressure created from flow of rescue air. Webbing may be configured in a cross hatch/grid pattern within the capsule wall to provide structure to the capsule wall. The capsule wall may collapsed when a victim is not configured in the capsule so that the capsule is easily carried by a rescuer.
