Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reusable respirator apparatuses face challenges in sealing performance, sanitization, reliability, ease of use, and usage tracking, particularly in providing effective protection against respiratory infectious agents like SARS, MERS, and COVID-19.
Innovation Solution
A reusable and resterilizable respirator apparatus with a mask body featuring filter chambers, disposable filter caps, and a strap harness system, incorporating flexible materials for ease of cleaning and sterilization, along with integrated communication components for tracking usage and inventory management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If disposable masks are widely used, then protection against respiratory infectious agents is improved, but cost and logistics pressure increase
Solution Approach 1:
The respirator is divided into reusable components (mask body, head harness) and disposable components (filter cartridges, filter caps). This segmentation allows the expensive reusable parts to be sterilized and reused multiple times, while only the consumable filters are discarded, significantly reducing overall cost and logistics burden compared to entirely disposable masks.
Solution Approach 2:
The patent implements a system where filter cartridges and filter caps are discarded after use, while the mask body and head harness are recovered, sterilized, and reused. This selective discarding and recovering approach maintains protection effectiveness while reducing waste and cost.
2Quantity of substance
If reusable respirator apparatuses are used, then cost and logistics pressure are reduced, but sanitization and sterilization challenges increase
Solution Approach 1:
By separating the respirator into reusable and disposable parts, the patent enables focused sanitization of only the reusable components (mask body and head harness), while disposable parts (filter cartridges and caps) are discarded without requiring sterilization. This significantly reduces sanitization complexity.
Solution Approach 2:
The filter cartridges and filter caps are designed as disposable components that are discarded after use, eliminating the need to sterilize them. This allows the reusable components to be simplified in design while maintaining overall protection effectiveness.
3Quantity of substance
If reusable respirator apparatuses are used, then cost efficiency is improved, but sealing performance and reliability challenges increase
Solution Approach 1:
The patent specifies that the mask body must maintain specific physical parameters (structural integrity, flexibility within ranges) to ensure proper sealing against the face. These parameter controls ensure that even though the mask is reusable and cost-efficient, the sealing performance remains reliable when properly fitted.
4Loss of information
If complex tracking systems are added to reusable respirators, then usage tracking is improved, but device complexity increases
Solution Approach 1:
The reusable mask body is designed to serve multiple functions: providing respiratory protection, enabling sterilization cycles, and incorporating usage tracking capabilities. This multi-functionality allows a single device to handle both protection and data collection without requiring entirely separate systems.
