Fire Evacuation Mask with Breakable Liquid Receptacle

Solution Overview

Problem

Conventional fire evacuation masks are cumbersome to adjust in urgent situations, may not fit snugly without manual adjustment, and dry masks are ineffective in blocking toxic gases and dust, with wet masks prone to contamination and evaporation.

Innovation Solution

A face mask design integrating a dry filter part with a liquid receptacle that absorbs liquid to enhance gas blocking, featuring a chin-tightening dual structure, one-way filter, and corrugated goggle part for clear vision, allowing quick donning and effective protection against toxic gases.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a dry mask is used for fire evacuation, then the mask is easy to store and package, but it cannot effectively block toxic gases and dust

Engineering Contradiction:

Improveease of storageVSAvoideffectiveness in blocking toxic gases

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The mask is pre-packaged in a sealed state with the filter member inside a breakable liquid receptacle. The liquid is contained in advance, and the packaging is designed to be broken only when needed. This allows the mask to be stored easily in dry form while being prepared in advance to become effective when activated by breaking the receptacle and allowing liquid to saturate the filter member.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If a wet mask is used for fire evacuation, then it can effectively block toxic gases, but it is prone to contamination and evaporation requiring frequent replacement

Engineering Contradiction:

Improveeffectiveness in blocking toxic gasesVSAvoidfrequency of replacement

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The mask is pre-packaged in a sealed state with the filter member inside a breakable liquid receptacle. The liquid is contained in advance, and the packaging is designed to be broken only when needed. This allows the mask to be stored easily in dry form while being prepared in advance to become effective when activated by breaking the receptacle and allowing liquid to saturate the filter member.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The mask is designed as a disposable product with a breakable liquid receptacle that is sealed during storage. After use, the entire mask including the liquid receptacle is discarded. This eliminates the need for cleaning and maintenance, and ensures that each mask provides reliable protection for its intended use period without contamination or evaporation issues.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Reliability

If the mask straps are adjusted in urgent situations, then the mask can fit snugly, but the adjustment process exposes the wearer to danger for extended time

Engineering Contradiction:

Improvemask fit securityVSAvoidadjustment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The mask is designed with pre-adjusted elastic straps that come in multiple length options to accommodate different head sizes. The straps are pre-tensioned and configured during manufacturing to provide a snug fit without requiring user adjustment. This preliminary configuration allows wearers to quickly don the mask in emergency situations without needing to spend time adjusting the straps.

Inventive Principle:

Principle #10Preliminary action

4Speed

If the mask is worn without adjusting the straps, then the wearer can evacuate immediately, but the mask may not fit snugly requiring manual holding

Engineering Contradiction:

Improveevacuation speedVSAvoidmask fit security

Core Design Contradiction:

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

Facilitates rapid and secure fitting, effectively blocks toxic gases and dust, and maintains protection without the need for frequent replacement, ensuring reliable respiratory safety during fires.

Implementation Method 1

a filter part which is coupled to a filter mounting part of the facial part, and includes a filter member for filtering the wearer's inhalation

Methodology Applied

Scientific EffectFiltration: Filter (physical)

Implementation Method 2

a one-way filter for exhausting the wearer's exhalation

Methodology Applied

Scientific EffectOne-way flow: Valve

Implementation Method 3

liquid is discharged from the liquid receptacle and is absorbed into a filter member, thereby more effectively blocking the inhalation of toxic gases

Methodology Applied

Scientific EffectAbsorption: Absorption (physical)

AI summary

Described is a face mask for fire evacuation, in which a case for the purpose of exhaust is integrated with a filter part of a respiratory mask to block toxic gases generated in the event of fire, thereby improving the convenience in respiration of a wearer, and protecting the respiratory system during the occurrence of toxic gases due to fire. The face mask for fire evacuation includes a liquid receptacle in the case, which allows liquid to be discharged from the liquid receptacle and absorbed into a filter member as needed when wearing the mask, thereby more effectively blocking the inhalation of toxic gases and enhancing safety.
