Scent Releasing Layer for Face Mask Odor Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The widespread and prolonged use of face masks due to the COVID-19 pandemic has led to increased discomfort from unpleasant odors, necessitating the development of masks that can release desirable scents.
Innovation Solution
Face masks with a scent releasing layer, either integrated into a cloth mask with a pocket or positioned between layers of a disposable mask, utilizing water-soluble polymers and essential oils to provide a pleasant aroma that can expire after a predetermined time, indicating the mask's useful life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face masks are worn for longer periods and by a larger portion of the public, then health protection benefits increase, but unpleasant odor experience increases
Solution Approach 1:
The patent converts the harmful odor accumulation problem into a beneficial scent release feature by incorporating essential oils (citrus, floral, or mint scents) into the mask structure. The essential oils are positioned to release pleasant aromas that counteract unpleasant odors, transforming the negative sensory experience into a positive one while maintaining health protection functionality
Solution Approach 2:
The patent changes the olfactory parameter of the mask by introducing scented components (essential oils, aromatic compounds) that alter the scent profile from unpleasant to pleasant. This parameter modification addresses the odor-related discomfort without compromising the mask's protective function
2Object-affected harmful factors
If a scent releasing layer is integrated into the mask, then pleasant aroma is provided, but mask structure becomes more complex
Solution Approach 1:
The patent merges the scent release function with the existing mask structure by integrating essential oils directly into the mask material or incorporating a scented insert that fits within the mask framework. This consolidation approach provides aromatic benefits while minimizing additional structural complexity
Solution Approach 2:
The patent creates a multi-functional mask that simultaneously provides health protection, comfortable fit, and pleasant aroma. The scented components are designed to work within the existing mask architecture, allowing a single device to fulfill multiple functions without requiring separate systems
3Object-affected harmful factors
If essential oils are used in the scent releasing layer, then desirable scent is provided, but oil may transfer to the user's face
Solution Approach 1:
The patent introduces an intermediary carrier material or coating layer that holds the essential oils and releases them slowly without direct contact with the user's face. This intermediary mechanism prevents oil transfer while maintaining the aromatic benefit, acting as a buffer between the scented component and the user's skin
