Strapless Magnetic Mask Coupling for Skin Irritation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional respiratory masks cause pressure sores and skin irritation due to straps, are cumbersome for long-term wear, and difficult to quickly remove in urgent situations.
Innovation Solution
A strapless respiratory mask design utilizing magnetic coupling elements to securely attach to the face, with a flexible harness and adhesive anchoring elements that allow for easy mounting and dismounting, reducing skin irritation and minimizing pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional straps are used to hold the mask, then the mask is securely attached to the face, but pressure sores and skin irritation occur due to prolonged wear
Solution Approach 1:
The patent removes the strap component entirely from the mask system and replaces it with magnetic coupling elements that attach directly to the mask body and corresponding magnetic anchoring elements on the wearer's face, eliminating the source of skin irritation and pressure sores
Solution Approach 2:
The patent replaces the mechanical strap-based attachment system with a magnetic field-based coupling system, where magnetic coupling elements and magnetic anchoring elements create secure attachment through magnetic attraction without physical contact with skin surfaces
2Reliability
If straps are used to secure the mask, then the mask remains fixed during long-term wear, but the mask becomes cumbersome and difficult to quickly remove in urgent situations
Solution Approach 1:
The patent creates a dynamic attachment system where the magnetic coupling elements can be easily engaged and disengaged by simply moving the mask away from the face, allowing rapid removal in urgent situations while maintaining secure fixation during normal use
Solution Approach 2:
The patent divides the attachment system into separate magnetic coupling elements on the mask and magnetic anchoring elements on the face, allowing independent movement and easy separation without the need to undo complex strap mechanisms
3Reliability
If adhesive materials are used to attach the mask, then the mask can be held securely to the face, but the mask becomes difficult to remove and reattach
Solution Approach 1:
The patent replaces adhesive-based attachment with magnetic field-based coupling, eliminating the need for chemical bonding that becomes permanent over time, and allowing simple physical separation and reattachment through magnetic attraction and repulsion
