Magnetic Face Mask Shield Assembly to Prevent Exhalation Fogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing face masks and shields are cumbersome, fog up during exhalation, and require simultaneous removal for adjustments, leading to reduced visibility and increased time consumption.
Innovation Solution
A combined face mask and shield system with a magnetic engagement structure and venting pathways to direct exhaled air away from the shield, ensuring clear visibility and easy adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a shield is worn to protect the face from air particulates, then face protection is improved, but the shield becomes foggy during exhalation impairing eyesight
Solution Approach 1:
The patent introduces an intermediary airflow management system between the user's exhalation and the shield surface. Venting pathways and channels redirect exhaled air away from the shield, preventing direct contact that causes fogging, while maintaining the shield's protective function against air particulates.
2Object-affected harmful factors
If both mask and shield are worn concurrently for comprehensive protection, then protection effectiveness is improved, but adjustment and manipulation become time-consuming
Solution Approach 1:
The patent merges the mask and shield into a single integrated assembly where the shield is selectively engageable with the mask. This combination allows the user to adjust both components simultaneously as one unit, eliminating the need for separate adjustments and reducing time consumption while maintaining comprehensive protection.
Solution Approach 2:
The patent introduces dynamic engagement mechanisms including magnetic engagement structures and snap-fit connectors that allow for quick attachment and detachment of the shield to the mask. This dynamic design enables rapid adjustment and manipulation without requiring complete removal and reattachment, significantly reducing adjustment time.
3Device complexity
If shield is attached by single band around head for simplicity, then device complexity is reduced, but shield moves and separates from user's head
Solution Approach 1:
The patent segments the attachment system into multiple independent components: a headband for general support, magnetic engagement structures for precise positioning, and snap-fit connectors for secure attachment. This segmentation allows each component to perform its specific function, providing stable shield positioning while keeping individual components relatively simple.
4Ease of operation
If mask is adjusted frequently for comfort and fit, then ease of operation is improved, but mask moves and separates from user's face
Solution Approach 1:
The patent merges the mask and shield into an integrated assembly where adjustments to the combined unit maintain the relative positions of both components. The shield is selectively engageable with the mask, allowing the user to adjust the entire assembly as one unit, ensuring the mask remains properly positioned on the face while providing easy adjustment capability.
