Bioplastic Respirator Mask with Sliding Gate and Segmented Filters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current respirator masks are made from toxic materials like PET, PVC, and microplastics, causing health issues such as reduced blood oxygen levels, headaches, and skin irritation, and do not allow for easy eating, drinking, or speaking while maintaining air filtration and exhale protection.
Innovation Solution
A respirator oxygen mask with a straw opening, adjustable face sizing, and eco-friendly bioplastic material, featuring a two-way air filter and a sliding mask gate for eating and speaking, along with a face mask reduction attachment for universal sizing and improved airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cloth masks or N95 respirators are used, then air filtration is improved, but user comfort and health are worsened due to toxic materials and reduced oxygen levels
Solution Approach 1:
The patent changes the material parameter from toxic petroleum-based polymers (PET, PVC) to non-toxic bioplastic materials, fundamentally altering the chemical composition to eliminate harmful effects while maintaining protective functions
Solution Approach 2:
The mask combines multiple materials including bioplastic components, activated carbon filters, and hydrophilic membrane layers to create a composite structure that provides both protection and comfort without toxic substances
2Reliability
If N95 masks with effective filters are worn, then virus protection is improved, but breathing difficulty and headaches are worsened due to reduced oxygen levels
Solution Approach 1:
The mask divides the breathing system into separate inlet and outlet pathways with dedicated filters for each, allowing independent optimization of filtration and airflow to maintain oxygen levels while providing virus protection
Solution Approach 2:
The patent introduces a hydrophilic membrane as an intermediary layer that facilitates efficient gas exchange and moisture management, enabling comfortable breathing while maintaining effective filtration
3Duration of action of stationary object
If current masks are worn for extended periods, then continuous protection is improved, but skin irritation and rash are worsened due to large surface area contact
Solution Approach 1:
The mask uses flexible bioplastic materials and thin film structures that conform to the face without excessive pressure, reducing skin irritation while maintaining protective coverage for extended periods
Solution Approach 2:
The patent employs disposable bioplastic components that can be easily discarded after use, preventing skin irritation from prolonged contact with reusable materials that may harbor bacteria or degrade
4Reliability
If current masks are worn, then air filtration is improved, but ability to eat, drink, and speak is worsened
Solution Approach 1:
The mask incorporates dynamic elements such as movable flaps or valves that can open during eating and speaking activities and close during normal breathing, allowing temporary suspension of filtration barriers when communication or consumption is needed
Solution Approach 2:
The mask integrates multiple functions including filtration, breathing, eating, and speaking capabilities into a single device, eliminating the need to remove the mask for these activities while maintaining protective functions
5Quantity of substance
If current oxygen masks are used, then oxygen delivery is improved, but exhale filtration is worsened allowing contaminated air to be breathed out
Solution Approach 1:
The mask separates the inhalation and exhalation pathways with distinct filters for each direction, allowing oxygen delivery to be optimized in the inlet while dedicated outlet filtration prevents contamination in the exhaled air
Solution Approach 2:
The mask applies different filtration qualities to different locations - the inlet uses filters optimized for oxygen delivery while the outlet uses filters specifically designed for capturing and filtering exhaled contaminants
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
