Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing masks face challenges such as difficulty in breathing due to airflow restriction, moisture buildup, high cost, and inability to see the wearer's face or communicate effectively, especially in environments with poor ventilation or during emergencies like fires or underwater.
Innovation Solution
A transparent mask equipped with an oxygen supply system, featuring air inflow and discharge ports with flaps, filters, and branch pipes for oxygen and external air intake, allowing seamless breathing and visibility, even in challenging environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mask body and filter body are configured in a dual structure, then pathogen blocking capability is improved, but breathing smoothness deteriorates
Solution Approach 1:
The mask is divided into a transparent mask body and a separate filter part. The filter part is detachably coupled to the mask body, allowing independent optimization of each component's function while maintaining overall system performance.
Solution Approach 2:
A coupling part acts as an intermediary between the mask body and filter part, enabling easy attachment and detachment while ensuring proper sealing and airflow path formation between the two components.
2Object-affected harmful factors
If a mask body and filter body are configured in a dual structure with separate suction and discharge, then moisture formation is reduced, but device complexity increases
Solution Approach 1:
The filtering function is separated into a distinct filter part with multiple layers (first filter layer, second filter layer, and membrane layer), while the mask body handles airflow management through separate inlet and outlet paths.
Solution Approach 2:
The filter part utilizes porous membrane materials with specific pore structures to achieve effective filtration of pathogens and particles while maintaining breathable airflow characteristics.
3Ease of operation
If a transparent mask is used, then face visibility is improved, but adaptability to poor ventilation environments deteriorates
Solution Approach 1:
The mask system is designed to accommodate multiple environments and uses through optional configurations. The filter part can be selectively attached or detached based on environmental requirements, and the coupling mechanism allows for easy adjustment of filtration levels.
Solution Approach 2:
The coupling part enables dynamic adjustment of the filter part's position and attachment state, allowing the user to adapt the mask's filtration capability to match varying environmental conditions such as indoor/outdoor settings or different ventilation qualities.
4Ease of operation
If a transparent plastic film is used for the mask body, then face visibility is improved, but manufacturing precision requirements increase
Solution Approach 1:
The transparent mask body is designed as a separate component from the filter assembly, allowing each part to be manufactured and quality-checked independently. This segmentation simplifies the manufacturing process for each component while maintaining overall system integrity.
Solution Approach 2:
The mask body utilizes flexible transparent material that can be molded into shapes conforming to facial contours, achieving both visibility and comfort without requiring extremely tight manufacturing tolerances.

Implementation Method 1
a discharge flap (132) which allows air to be discharged to the outside of the transparent member (110) as it moves
Implementation Method 2
an inner surface of the flow path of the various patterns is configured to have adhesive or adsorbent for adsorbing contaminants applied thereto during passing of the air containing external harmful substances through the flow path
Implementation Method 3
a filter part provided on a lower surface of the mask body to purify the sucked air
