Expandable Containment Chamber with P95 Filter for Airborne Pathogen Trapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a portable, cost-effective means to prevent the transmission of airborne diseases without the stigma of wearing a surgical mask, particularly in confined environments where individuals with airborne diseases interact with others.
Innovation Solution
A portable containment device with an expandable chamber and a filter, configured to entrap airborne particles, which can be easily extended for use and collapsed for storage, utilizing a microporous polypropylene-based material with a NIOSH-approved P95 or N95 rating filter to trap respiratory droplets and pathogens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a surgical mask is worn to block spittle and respiratory particles, then protection against airborne diseases is improved, but social stigma and discomfort increase
Solution Approach 1:
The device segments the containment function into a separate portable chamber that can be activated only when needed, rather than requiring continuous wear of a surgical mask. The chamber is divided into a containment space and a filter system, allowing targeted protection without constant mask wear.
Solution Approach 2:
The portable containment device is designed as a disposable unit that can be discarded after single use, eliminating the need for cleaning and reuse. This approach reduces the barrier to use by avoiding stigma associated with reusable masks, while still providing effective protection during the brief period when airborne particles are emitted.
2Reliability
If a portable containment device with expandable chamber is used, then protection in confined environments is improved, but device complexity increases
Solution Approach 1:
The chamber is designed with dynamic expandability, allowing it to transition from a compact stored state to an expanded operational state. The vertical wall can be selectively expanded to increase containment volume when needed, and collapsed for storage, providing adaptability without permanent complexity.
Solution Approach 2:
The chamber utilizes a flexible vertical wall that can be expanded and collapsed, allowing the containment volume to be adjusted based on operational needs. This flexible structure provides the necessary containment capability while maintaining portability and reducing stored complexity.
3Reliability
If the chamber is expanded for use, then containment effectiveness is improved, but storage space requirements increase
Solution Approach 1:
The chamber volume is made dynamic rather than fixed, allowing expansion during use to provide effective containment and collapse during storage to minimize space requirements. The vertical wall can be selectively expanded and collapsed, transforming the device between operational and stored states.
Solution Approach 2:
The chamber structure is designed to collapse into a compact form for storage, similar to nested dolls, allowing the expanded containment volume to be stored within a small footprint. This enables the device to provide effective containment when needed while occupying minimal storage space when not in use.
