Full-face diving mask partition plates and one-way valves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing full-face diving masks suffer from ineffective separation of inhalation and exhalation channels, leading to re-inhalation of carbon dioxide and fogging due to mixed exhaled air and water vapor, especially in low temperature water.
Innovation Solution
A full-face diving mask design with partition plates and one-way valves separates the air compartments for inhalation and exhalation, ensuring that exhaled air is directed away from the inhalation path and preventing water entry, while an adjustable breathing tube facilitates comfortable and safe underwater breathing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single one-way valve is provided in existing full-face diving masks, then the structure is simple, but the intake and discharge of air cannot be effectively separated, causing carbon dioxide re-inhalation
Solution Approach 1:
The patent divides the breathing system into separate intake and discharge channels with multiple one-way valves (intake valve, discharge valve, and secondary discharge valve) positioned at different locations. This segmentation ensures that inhalation and exhalation paths are completely separated, preventing carbon dioxide re-inhalation while maintaining structural reliability.
2Reliability
If exhaled air is mixed with water vapor in low temperature water, then the breathing process is simple, but condensation forms on the inner surface of the mask causing fogging
Solution Approach 1:
The patent extracts and separates the exhaled air flow path from the general breathing space using dedicated discharge channels and multiple one-way valves. By directing exhaled air and water vapor through specific discharge paths away from the lens housing, the system prevents condensation on the inner mask surface, eliminating fogging while maintaining breathing function.
3Ease of operation
If the breathing tube is integrated with the mask to facilitate breathing, then ease of operation is improved, but the structure becomes more complex and requires effective separation of air compartments
Solution Approach 1:
The integrated breathing tube system is segmented into distinct functional zones with multiple one-way valves (intake valve near the top, discharge valve in the middle, secondary discharge valve at the bottom) that create separate air compartments. This segmentation allows the breathing tube to be integrated with the mask for ease of operation while internally separating inhalation and exhalation paths to manage complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces carbon dioxide re-inhalation and fogging, enhancing user comfort and safety by ensuring efficient exhalation and preventing water ingress, thus improving the overall breathing experience underwater.
Implementation Method 1
At least one valve located on the first partition plate permitting the transfer of air from the upper air compartment to the lower air compartment and preventing the transfer of air from the lower air compartment to the upper air compartment
Implementation Method 2
A first partition plate divides the cavity between an upper air compartment located adjacent to the user's eyes and a lower air compartment located adjacent to the user's nose and mouth
Implementation Method 3
The face opening is configured to seal against the portion of the user's face and prevent water from entering the cavity when the full-face diving mask is worn

AI summary
A full-face diving mask includes a mask and a breathing tube. The mask includes an outer frame, a lens housing and a fitting mask. The fitting mask includes a partition plate. The partition plate and the inner surface of the lens housing define an observation chamber on the top and a breathing chamber below. The partition plate includes at least one air intake port to allow inhaled air to be guided and circulated through at least one air intake passageway from the observation chamber toward the breathing chamber. The breathing chamber is further provided with an air compartment partition plate connected to the partition plate to define an air discharge compartment. The air compartment partition plate is provided with at least one air discharge port to allow exhaled air to be guided through at least one air discharge passageway from the air discharge compartment and discharged along the breathing tube.
