Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing masks and valves are often separate components, leading to poor performance and potential air backflow into the user's airway, exacerbating conditions and posing safety hazards, particularly in devices like anti-choking devices and emergency respirators.
Innovation Solution
A mask with an integrated one-way valve assembly that allows airflow in one direction only, enhancing the mask's design to prevent air backflow and ensure safe airflow during vacuum creation processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If masks and valves are used as separate components, then device complexity is reduced and ease of manufacture is improved, but reliability deteriorates due to poor performance and air backflow into the user's airway
Solution Approach 1:
The patent integrates the valve assembly directly into the mask body, combining two previously separate components (mask and valve) into a single integrated unit. This merging eliminates the interface between separate components, preventing air backflow and improving reliability while maintaining manageable complexity through functional integration.
2Reliability
If an integrated valve assembly is added to the mask, then reliability is improved by preventing air backflow, but device complexity increases
Solution Approach 1:
The valve assembly is merged with the mask body to form an integrated unit, where the valve is positioned within the mask structure. This integration ensures that air can only flow in the intended direction (from mask to airway) and prevents backflow into the user's airway, improving reliability while keeping the overall device complexity manageable through unified design.
3Object-affected harmful factors
If separate masks and valves are used, then ease of manufacture is improved, but safety deteriorates due to potential air backflow exacerbating user conditions
Solution Approach 1:
By integrating the valve assembly into the mask body, the patent eliminates the harmful effect of air backflow into the user's airway. The unified structure ensures proper airflow direction control, preventing exacerbation of user conditions. While manufacturing becomes slightly more complex, the integrated design simplifies assembly and ensures consistent performance, offsetting the initial manufacturing complexity.

AI summary
A mask with a valve which provides protection for a device with the mask in multiple fields. The mask includes three parts: a mask body, a connecting part, and a valve assembly. The mask body has a first side and a second side, configured to at least partially cover the entrance of a nasal and/or oral airway of the user; the connecting part has a third side and a fourth side, configured to connect to the mask body and allow gas to enter or exit the mask body; the valve assembly is provided on a through passage which is formed by extending on both sides of the connecting part and is configured to allow airflow to pass through the connecting part in one direction only. Moreover, the disclosure achieves more effective use of the mask by defining the valve assembly.
