Reconfigurable Full Facemask with Interchangeable Cartridge Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing full facemasks require separate fit testing for each configuration, which is time-consuming and costly, and manufacturers seek simpler and less expensive methods of manufacturing, while users desire the ability to reconfigure facemasks without re-performing fit tests.
Innovation Solution
A full facemask design featuring a face seal with a mask lens and a cartridge module that includes a locking mechanism allowing quick release and reconfiguration of functional components, such as filters and air regulators, enabling the same mask lens to be used with different cartridge modules for various applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple facemask designs are used for different applications, then adaptability to various hazardous environments is improved, but fit testing requirements and costs increase
Solution Approach 1:
The facemask is designed with a universal configuration where the lens piece and face seal remain fixed, while functional components (filters, regulators, etc.) are standardized and interchangeable. This allows a single fit-tested facemask design to serve multiple applications by simply swapping the cartridge module, eliminating the need for separate fit tests for each application-specific variant.
Solution Approach 2:
The facemask is divided into distinct functional modules: a fixed lens piece, a fixed face seal, and interchangeable cartridge modules. This segmentation allows the critical fit-testing components (lens and face seal) to remain constant while only the non-critical functional components (cartridges) are changed, maintaining fit test validity across multiple configurations.
2Adaptability or versatility
If multiple facemask designs are used for different applications, then functional requirements for different tasks are met, but manufacturing complexity increases
Solution Approach 1:
By creating a universal facemask platform with standardized interfaces and a common lens piece design, the manufacturer can produce one base model that serves multiple functions. Different applications are achieved through interchangeable cartridge modules rather than designing entirely different facemasks, significantly reducing manufacturing complexity.
Solution Approach 2:
The patent combines multiple functional components (filters, regulators, exhalation ports) into a single integrated cartridge module that attaches to the universal facemask body. This merging reduces the number of separate parts that need to be manufactured and assembled, simplifying the overall manufacturing process while maintaining functional versatility.
3Stability of the object's composition
If traditional facemask configurations are used, then structural integrity is maintained, but reconfiguration capability is limited
Solution Approach 1:
The facemask is segmented into a stable, fixed structural component (lens piece with face seal) and a replaceable functional component (cartridge module). This segmentation allows the structural integrity of the lens and face seal to be maintained while enabling easy reconfiguration by swapping cartridges, resolving the contradiction between stability and adaptability.
Solution Approach 2:
The facemask incorporates a dynamic reconfiguration capability where the cartridge module can be quickly attached and detached from the fixed lens piece. This dynamic feature allows the system to adapt to different functional requirements without compromising the structural integrity of the permanent components, enabling both stability and versatility.

AI summary
Full facemask including a face seal configured to directly engage a face of an individual. The face seal defines a lens opening. The full facemask also includes a mask lens that is coupled to the face seal and disposed within the lens opening. The mask lens has a passage edge that defines a cartridge passage through the mask lens. The full facemask also includes a cartridge module having at least one of a filter or an air regulator. The cartridge module is disposed within the cartridge passage and circumscribed by the passage edge of the mask lens. The full facemask also includes a locking member that includes a first member surface that directly engages the mask lens and a second member surface that directly engages the cartridge module. The locking member secures the mask lens and the cartridge module in fixed positions with respect to each other.
