Anti-fog Diving Mask Nose Zone Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Diving masks often fog up due to damp air from the diver's nose, reducing visual ability, and existing anti-fog solutions are not consistently effective or long-lasting.
Innovation Solution
A diving mask design featuring a rigid frame, soft and elastically yielding face mask with obstructing means, such as ribs or channels, that separate the internal space into zones to prevent direct airflow from the nose from reaching the lenses, either by creating an airtight separation or redirecting air to cool before reaching the lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If special treatments are applied to the internal surface of the lenses to reduce fogging, then anti-fog effect is achieved, but the effect is not long-lasting and satisfactory
Solution Approach 1:
The internal space of the face mask is segmented into two separate zones by the obstructing means: a first zone behind the lenses and a second zone containing the nose cavity. This segmentation prevents damp air from the nose from reaching the lenses, providing a reliable and long-lasting anti-fog solution without requiring complex surface treatments of the lenses themselves.
2Reliability
If the internal space is divided into separate zones to prevent damp air flow, then fogging is prevented, but the mask structure becomes more complex
Solution Approach 1:
The obstructing means acts as an intermediary element within the face mask structure, dividing the internal space without requiring complete redesign of the mask. This rib or partition structure is integrated into the existing face mask material and creates the necessary zone separation with minimal additional 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
Effectively prevents fogging of the lenses by redirecting or blocking damp air from the nose, maintaining clear vision for divers.
Implementation Method 1
the internal surface of said face mask is equipped with obstructing means obstructing a direct flow towards said at least one lens of the air released from the diver nose
Implementation Method 2
obstruction means just channels said air towards a channel surrounding said at least one lens to avoid a direct flow towards said at least one lens of the air released from the diver nose. This way, before reaching said at least one lens, the air traveling along said channel cools down enough to avoid or at least limit fogging up of said at least one lens

AI summary
The diving mask includes a rigid frame, one or two lenses, and a face mask made of soft and elastically yielding material, the face mask having a front hollow projection for housing the nose of the diver and a rear perimeter profile applicable in an airtight way to the face of the diver so as to delimit an internal space between the mask and the face of the diver, the internal surface of said face mask being equipped with obstructing means obstructing a direct flow towards lenses of the air released from the diver nose.
