Mouth Insert With Airflow-Driven Baffle for Blocking Mouth Inhalation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices that restrict mouth breathing fail to completely prevent air intake, reinforcing the habit of mouth breathing and defeating the purpose of training to breathe through the nose.
Innovation Solution
A mouthpiece with a movable baffle that blocks air intake when inhaling through the mouth and generates an audible alert, training the user to breathe through the nose by preventing mouth inhalation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a mouth covering device is used to restrict air intake through the mouth, then mouth breathing is reduced, but the device does not completely block air flow and may reinforce the mouth breathing habit
Solution Approach 1:
The patent employs a movable baffle that dynamically responds to airflow direction. The baffle is positioned to block the air hole during inhalation when the user attempts to breathe through the mouth, while allowing air flow during exhalation. This dynamic positioning ensures complete blockage of harmful mouth inhalation while maintaining necessary breathing functions.
Solution Approach 2:
The patent incorporates an audible alert mechanism that provides feedback when the user attempts to inhale through the mouth. The alert sounds when the baffle blocks the air hole, notifying the user of improper breathing technique and reinforcing the training to breathe through the nose. This feedback loop strengthens the corrective effect of the device.
2Object-affected harmful factors
If the baffle blocks the air hole completely during inhalation, then mouth breathing is prevented, but the device complexity increases
Solution Approach 1:
The baffle mechanism is designed to be self-actuating through airflow pressure differentials. During inhalation, negative pressure automatically moves the baffle to block the air hole. During exhalation, positive pressure automatically moves the baffle to open the air hole. This self-service mechanism eliminates the need for external power sources, control systems, or complex actuation mechanisms.
Solution Approach 2:
The patent utilizes pneumatic pressure differentials created by the user's own breathing to drive the baffle movement. The natural pressure changes during inhalation and exhalation provide the force needed to position the baffle correctly, converting the user's breathing action into the controlling force for the blocking mechanism.
3Ease of operation
If the device restricts air intake at the mouth, then nose breathing is encouraged, but the restricted intake may reinforce the habit of inhaling harder through the mouth
Solution Approach 1:
The device performs preliminary blocking of the air hole before the user can complete a mouth inhalation. By positioning the baffle to block the air hole in advance during the inhalation phase, the device prevents the harmful action from completing, thereby breaking the habit loop before it can reinforce itself.
Solution Approach 2:
The audible alert provides immediate feedback when the user attempts to inhale through the mouth, creating a disruptive feedback loop that prevents the reinforcement of the mouth breathing habit. The alert interrupts the automatic response and draws attention to the improper technique.
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 trains users to breathe primarily through their nose by blocking mouth inhalation and providing audible feedback, improving respiratory health and performance.
Implementation Method 1
The baffle is configured to block the inflow of air at the air hole when a user attempts to inhale through their mouth
Implementation Method 2
The baffle is movable between the backstop and the impact surface... The baffle moves along the guiding tracks to the impact surface and blocks the air hole when a person inhales through the mouth insert
Implementation Method 3
an audible alert is generated when the air hole is blocked. The audible alert may be generated by the movement of the baffle against the impact surface of the second end
Data Source
AI summary
A one-way breath training device has a mouth insert engaged to a cage housing a movable baffle. The mouth insert has an air hole extending from a first end to a second end. The baffle moves within the cage between a backstop having air pathways therethrough to the second end of the mouth insert. The cage has one or more guidance tracks which the baffle moves along. When a user attempts to inhale through their mouth, the inflow of air pulls the baffle against the second end and blocks the air hole to prevent further air from entering the air hole. When a user exhales through the mouth insert, the outflowing air pushes the baffle against the backstop of the cage thereby opening the air hole and air pathways for the exhaled air to escape.
