Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional masks cause moisture buildup and skin issues due to breathing, leading to fogging and reduced visibility, and fail to prevent the spread of viruses effectively.
Innovation Solution
A nose breathing device with inhaling and exhaling tubes, check valves, and a discharge hose that directs exhaled air outside the mask, combined with a purification device to filter harmful substances, preventing reverse airflow and maintaining mask cleanliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mask is worn to block foreign substances and dust, then protection against respiratory diseases is improved, but moisture buildup and skin troubles occur due to repeated inhalation and exhalation
Solution Approach 1:
The breathing process is segmented into separate inhalation and exhalation pathways. The mask includes a breathable membrane that allows inhalation while blocking pathogens, and a separate exhalation vent that releases moisture and warm air directly outward, preventing moisture accumulation inside the mask that causes skin troubles
Solution Approach 2:
The harmful exhaled air containing moisture and warmth is extracted and directed outward through a dedicated exhalation vent located above the nose. This separates the exhalation function from the general mask coverage, allowing moisture to be removed from the mask interior environment that contacts the skin
2Duration of action of stationary object
If a mask is worn for extended periods, then continuous protection is maintained, but skin around the nose and mouth becomes exposed to moisture causing skin diseases
Solution Approach 1:
The exhalation vent continuously extracts and removes warm, moist air from the mask interior during each breath cycle. This active removal prevents moisture accumulation on the skin surface, allowing the mask to be worn for extended periods without causing skin diseases
Solution Approach 2:
The exhalation vent is specifically positioned above the nose to target the local area where moisture accumulation most frequently occurs. The breathable membrane material also provides local quality by being selectively permeable to water vapor while blocking pathogens
3Temperature
If humidity increases due to temperature difference between inner and outer mask during winter breathing, then moisture formation occurs on inner mask surface, but the mask must be removed and glasses fogging occurs
Solution Approach 1:
The exhalation vent extracts warm, humid air directly from the breath path before it can condense into water drops on the mask interior surface. By removing this moisture-laden air through the vent above the nose, both water drop formation and glasses fogging are prevented
Solution Approach 2:
The exhalation vent performs preliminary action by removing warm, humid air during exhalation before condensation can occur. This prevents the subsequent harmful effects of water drop formation and glasses fogging that would otherwise require mask removal to resolve
4Object-generated harmful factors
If warm air is discharged through gap above nose during exhalation, then fogging occurs in glasses, but view obstruction results
Solution Approach 1:
The exhalation vent is positioned and configured to extract warm air directly from the breath path above the nose and discharge it outward. This captures and redirects the warm air that would otherwise flow forward and fog the glasses, maintaining clear view while still managing the warm air discharge
