Oxygen Generating Towel with Chemical Receptor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In emergency situations like fires, existing methods for preventing suffocation from toxic smoke are inadequate as they do not provide sustained oxygen supply, leading to limited survival time and potential damage from unnecessary oxygen generation when not in use.
Innovation Solution
A life-saving towel equipped with an oxygen generating device, comprising a filter sheet, an oxygen generating receptor, and an oxygen generating cover, using activated carbon and metal peroxides to produce oxygen while blocking toxic gases, with a durable design and adhesive bonding to prevent accidental oxygen generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If an oxygen generating device is integrated into the towel, then the survival time is extended through sustained oxygen supply, but the device complexity increases
Solution Approach 1:
The oxygen generating material is enclosed within a compact receptor structure that is integrated into the towel layers. The receptor contains the chemical components in a nested configuration, allowing the oxygen generation function to be embedded within the portable towel without significantly increasing its external dimensions.
Solution Approach 2:
The oxygen generating device is merged with the towel structure by integrating the receptor between the filter sheet and oxygen generating cover, which are themselves part of the towel assembly. This combines the respiratory protection function (filtering) with the oxygen supply function in a single integrated device.
2Speed
If the oxygen generating material is exposed, then oxygen is generated immediately in emergency, but unnecessary oxygen generation occurs when not in use causing product damage
Solution Approach 1:
The oxygen generating material is pre-prepared and positioned within the receptor, but kept in an inactive state during storage. The system is pre-configured with all necessary components (filter sheet, receptor, cover) in their proper positions, ready for immediate activation when the emergency occurs and the cover is removed.
Solution Approach 2:
The oxygen generating cover is separated from the receptor during storage to prevent contact between the oxygen generating material and atmospheric moisture. The cover is taken out or removed only when oxygen generation is needed, allowing controlled exposure of the reactive material.
3Reliability
If the oxygen generating cover is securely bonded, then unnecessary oxygen generation is prevented, but the ease of operation decreases when removal is needed
Solution Approach 1:
The bonding mechanism is designed to be dynamic rather than static - it provides strong adhesion during storage to prevent accidental activation, but allows for relatively easy removal when needed. The bonding portion enables the cover to be securely attached during storage, then readily detached during emergency use.

AI summary
A life-saving towel generates oxygen in the event of an emergency such as a fire to enable a user to survive for a long time. The life-saving towel includes: a filter sheet; an oxygen generating receptor in which an oxygen generating material is accommodated and which is coupled to one surface of the filter sheet; an oxygen generating receptor barrier frame in contact with the other surface of the filter sheet, which is coupled to the oxygen generating receptor with the filter sheet interposed therebetween and has a plurality of empty spaces formed therein; and an oxygen generating cover in contact with the other surface of the oxygen generating receptor barrier frame to cover all of the plurality of empty spaces of the oxygen generating receptor barrier frame and having a bonding portion formed on one surface to be bonded to the oxygen generating receptor barrier frame.
