Modular Protective Suit with Integrated Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional personal protective equipment (PPE) is cumbersome, expensive, and often ineffective in providing long-term protection against viral or bacterial contaminants, posing a high risk for healthcare workers and requiring multiple components that are difficult to use and maintain.
Innovation Solution
A modular, breathable, reusable, and fluid-proof protective suit with an integrated filtration system that provides an isolated air supply, using a PTFE N99% BFE filtration system and a fan-assisted air ventilation system to ensure air is filtered before inhalation and expelled without backflow, reducing physical stress and improving usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional PPE is used, then protection against contaminants is provided, but the equipment becomes cumbersome and physically taxing
Solution Approach 1:
The patent combines multiple PPE functions into a single integrated suit: the protective garment, filtration system, and air ventilation system are merged into one unified device. This eliminates the need for separate masks, respirators, and protective clothing, reducing the number of components while maintaining comprehensive protection and improving ease of use.
Solution Approach 2:
The protective suit serves multiple functions simultaneously: it provides physical barrier protection, filters airborne contaminants, supplies breathable air, and prevents fluid penetration. This multi-functionality replaces several separate PPE devices with one universal system that addresses all protection needs in hazardous environments.
2Reliability
If multiple protection methods are combined, then higher level protection is achieved, but device complexity increases
Solution Approach 1:
The patent integrates the filtration system and air ventilation system directly into the protective suit structure, eliminating the need for separate respirators and air supply devices. The faceplate with integrated filter and the connected ventilation system form a unified component rather than separate pieces of equipment.
Solution Approach 2:
The suit is divided into functional modules that can be independently manufactured and assembled: the protective garment component, the faceplate with filter, and the ventilation system. This modular segmentation allows for easier manufacturing and maintenance while presenting a unified system to the user.
3Reliability
If conventional PPE is used, then protection is provided, but it requires frequent cleaning and maintenance
Solution Approach 1:
The protective suit utilizes a fluid-proof membrane that acts as an impermeable barrier to contaminants while remaining flexible and breathable. This thin film structure is designed to be easily cleaned and disinfected, maintaining protection capability through simple maintenance rather than complex repairs.
4Reliability
If high-level filtration is implemented, then contaminant protection is improved, but airflow restriction increases
Solution Approach 1:
The filtration system employs porous filter media that allows air molecules to pass through while capturing larger contaminant particles. The porous structure provides numerous flow paths that maintain airflow velocity even with high filtration efficiency, resolving the trade-off between filtration and breathability.
Solution Approach 2:
The air ventilation system uses pneumatic principles to actively move air through the filtration system and into the suit interior. The ventilation mechanism creates positive pressure to drive airflow through the filter, ensuring adequate breathability even with high-efficiency filtration media in place.

Implementation Method 1
a filtering device configured to filter at least 95% of airborne particulates and configured to allow external air into the head cover (104) through the filtering device
Implementation Method 2
an air ventilation system configured to allow air to leave the cavity when the air ventilation system is activated without allowing air to enter the cavity from outside the suit regardless of whether the air ventilation system is activated or deactivated
Implementation Method 3
the hood (116) forms a fluid-tight seal with the faceplate (110) to form a cavity (114) between the wearer's face and the faceplate (110)
