Solution Overview

Problem

Full face diving masks sometimes make inhalation difficult, resulting in a sensation of not breathing in enough fresh air.

Innovation Solution

A full face diving mask with an assisted breathing device that includes a suction channel, motorized ventilation means, and a conveyor to forcibly inject air into the inhalation duct, along with a battery-powered system and immersion sensor for controlled operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a full face mask is used to cover the entire face including the mouth, then the watertight seal and vision are improved, but the inhalation operation becomes difficult and the user feels they are not breathing in enough fresh air

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

A motorized ventilation device is introduced as an intermediary between the external environment and the user's respiratory system. This device actively draws fresh air from the external environment through a suction channel and forces it into the inhalation duct, mediating the breathing process to overcome the difficulty of inhalation while maintaining the watertight seal of the full face mask

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The motorized ventilation device operates autonomously to provide assisted breathing. The device self-regulates by detecting immersion status through a sensor and automatically activating the ventilation motor when needed, allowing the mask system to service itself without requiring manual intervention from the user during operation

Inventive Principle:

Principle #25Self-service

AI summary

A diving mask includes a transparent visor, a frame, a gasket to guarantee the watertight seal and appropriate belts for fitting the mask, a breathing tube associated with the facial part is fitted onto the upper part of the mask and which enables the flow of air to enter into the compartment between the frame and the visor. The path of air in the inhalation phase and in the exhalation phase both in the mask and tube are different from each other. The tube is made with separate ducts for inhalation and exhalation and the inside of the mask is made with two compartments, one upper front and one lower oronasal separated by a wall. The path provides that inhalation air is introduced by the tube into the frontal compartment and then into the oronasal one and air exhaled from the oronasal compartment travels up to the tube.
