Replaceable Filter Cartridge Face Mask with Threaded Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing face masks lack a convenient and effective mechanism for replacing filter cartridges, which can lead to reduced filtration efficiency and increased exposure to environmental contaminants.
Innovation Solution
A face mask design featuring a replaceable filter cartridge with a closure system that includes a filter frame and multi-folded filter material, allowing for easy attachment and detachment, ensuring consistent filtration performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a replaceable filter cartridge mechanism is implemented, then filtration efficiency is maintained and exposure to contaminants is reduced, but device complexity increases
Solution Approach 1:
The face mask is divided into a reusable mask body and a replaceable filter cartridge assembly. The filter cartridge can be independently removed and replaced, allowing users to maintain filtration efficiency without replacing the entire mask. This segmentation enables the complex filtering function to be isolated in a replaceable module.
Solution Approach 2:
The filter cartridge is nested within a closure assembly that includes a closure member and a filter frame. The filter material is contained within the filter frame, which in turn is held by the closure. This nested structure allows multiple functional components to be integrated in a compact manner while maintaining the ability to replace just the filter cartridge.
2Reliability
If a secure closure system is used to ensure consistent seal, then filtration performance is maintained, but ease of operation for replacing cartridges is reduced
Solution Approach 1:
The closure member incorporates a threaded engagement system that allows dynamic adjustment between a secure locked state (when tightened) and a removable state (when unscrewed). This dynamic mechanism enables the closure to provide consistent sealing during use while allowing easy replacement when needed.
Solution Approach 2:
The closure member acts as an intermediary between the user's manual operation and the filter cartridge retention. By providing a threaded interface, it mediates between the simple rotational motion of the user and the secure mechanical engagement required for a consistent seal, making the replacement process both easy and reliable.

AI summary
Disclosed herein are methods and systems for face mask with replaceable filter cartridges and components. A face mask includes a mask component, a replaceable filter component, and a closure component. The replaceable filter component is bonded to and as between the closure component and the mask component when the closure component is attached to the mask component.
