Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing respiratory masks cause discomfort during long-term use due to inadequate airflow and are prone to accidental dislodging during sleep, necessitating improvements in design for comfort and security.
Innovation Solution
A respiratory mask with a ventilating portion and rotatable air pipe assembly, combined with a nose cushion assembly and adjustable head strap system, to enhance airflow and reduce accidental dislodging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mask is worn securely to prevent dislodgment during sleep, then the reliability of the mask is improved, but the comfort of the wearer deteriorates due to long-time usage
Solution Approach 1:
The mask is divided into multiple detachable components including the head strap assembly, air pipe assembly, and mask body. This segmentation allows the mask to maintain secure fit during use while enabling quick removal and disassembly, resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The head strap assembly incorporates rotatable connection portions that allow dynamic adjustment of the mask position and angle. This dynamic capability enables the mask to adapt to different sleeping positions, maintaining security while improving comfort during long-time usage.
2Duration of action of stationary object
If the mask is designed for long-time wear to improve sleep quality, then the duration of action is improved, but the discomfort from inadequate airflow increases
Solution Approach 1:
The air pipe assembly includes dedicated ventilating portions with through holes positioned at specific locations to optimize airflow distribution. This local quality enhancement ensures adequate ventilation throughout extended wear duration, reducing airflow-related discomfort.
Solution Approach 2:
The ventilating portions are designed to maintain continuous airflow through the mask structure during extended use. The rotatable connection portions ensure continuous adaptability to sleeping positions, maintaining effective ventilation throughout the entire wear duration.
3Ease of manufacture
If the mask structure is simplified for ease of manufacture, then the ease of manufacture is improved, but the ability to facilitate airflow and reduce discomfort deteriorates
Solution Approach 1:
The mask is constructed from multiple separately manufactured components that are assembled together. The air pipe assembly with ventilating portions can be manufactured independently and then integrated with the mask body, maintaining manufacturing simplicity while ensuring adequate airflow through the dedicated ventilating structure.
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 design provides improved comfort and secure fit, facilitating better airflow and quick disassembly, thereby enhancing user experience and reducing mask displacement during sleep.
Implementation Method 1
The first ventilating portion rotates relative to the shell and the curved pipe body rotates relative to the shell when the first positioning portion rotates relative to the second positioning portion

AI summary
Herein disclosed is a respiratory mask comprising a nose cushion assembly (16). The nose cushion assembly (16) comprises a base body (160) and a buffering piece (162). The base body (160) is defined as having a base intake portion (1600) and a base connection portion (1602). The base body (160) comprises an air routing piece (1604) disposed at the inside of the base body (160) and having a partitioning wall (1604b) and a wall connection piece (1604a). The inside of the partitioning wall (1604b) encloses an air intake zone (1604c). The wall connection piece (1604a) is disposed outside the partitioning wall (1604b) and connects with the base intake portion (1600). Between the partitioning wall (1604b) and the base intake portion (1600) there is defined an air outtake zone (1604d). The air intake zone (1604c) is approximately at the center of the base intake portion (1600). The buffering piece (162) connects with the base connection portion (1602) and encloses a nose containing room, which in turn connects with the inside of the base body (160).
