Movable Pressing Portion Nasal Device for Airflow and Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional nasal devices for sleep apnea struggle to balance easy insertion, sufficient airflow, and prevention of falling out of the nasal cavity, as larger devices are difficult to place and smaller ones fail to enlarge the nasal cavity effectively.
Innovation Solution
A nasal device with a tubular main body and a movable pressing portion that can shift between overlapping and protruding positions to expand the nasal cavity, ensuring easy insertion, increased airflow, and prevention of device displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the nasal device is made larger to enlarge the nasal cavity, then more air can pass through the airway, but the device becomes more difficult to place inside the nasal cavity
Solution Approach 1:
The pressing portion is designed to be movable, transitioning from a retracted state during insertion to a protruding state after insertion. This dynamic transformation allows the device to be inserted in a compact form and then expand to provide nasal cavity enlargement and improved airflow capacity.
2Ease of operation
If the nasal device is made smaller to facilitate insertion, then it is easier to place inside the nasal cavity, but the device cannot enlarge the nasal cavity effectively
Solution Approach 1:
The pressing portion transitions from a retracted state during insertion to a protruding state after insertion, enabling the device to expand the nasal cavity and improve airflow capacity after being inserted in a compact form.
Solution Approach 2:
The pressing portion moves in a lateral direction perpendicular to the longitudinal axis of the main body, creating expansion in a different dimension. This lateral movement allows the device to enlarge the nasal cavity width without increasing the longitudinal size that would complicate insertion.
3Reliability
If the nasal device is made larger to prevent falling out, then the device can stay in place better, but it becomes more difficult to insert
Solution Approach 1:
The pressing portion is movable between retracted and protruding states. During insertion, it remains retracted to minimize resistance. After insertion, it protrudes to press against the nasal cavity wall, providing retention and preventing the device from falling out.
Solution Approach 2:
The device is divided into a main body and a separate pressing portion that can move independently. This segmentation allows the pressing portion to be retracted during insertion for ease of placement, then protrude afterward to provide retention without interfering with the insertion process.

AI summary
This invention provides a nasal device comprising: a main body being tubular in shape having a hollow structure which extends from the end of front side to the end of rear side, wherein the main body is insertable into a nasal cavity; a front opening portion at the end of a front side of the main body and is configured to open the hollow structure towards the outside of the nasal device; a rear opening portion at the end of a rear side of the main body and is configured to open the hollow structure towards the outside of the nasal device; and a pressing portion placed at the rear end of the main structure and can move sideways from the rear end view in between a protruding position of the main body and an overlapping position that overlaps with the hollow structure.
