Solution Overview

Problem

Current mask systems for treating obstructive sleep apnea are cumbersome, uncomfortable, and difficult to use, leading to poor long-term adherence due to issues with sealing, weight, and complexity.

Innovation Solution

A frame assembly directly connected to a frame and a short tube, featuring a rigid frame that bends to fit the user's face, a detachable gas delivery hose with collapsible walls, and side connectors for secure attachment, simplifying use and enhancing comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a rigid frame combined with straps is used to secure the nasal pillow to the user's face, then the stability and sealing are improved, but the weight increases causing discomfort and pressure sores

Engineering Contradiction:
ImprovesealingVSAvoidweight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The patent replaces the traditional rigid frame structure with a flexible headgear assembly that uses elastic bands and soft contact surfaces. The headgear includes a flexible band that wraps around the head and a soft contact surface that interfaces with the user's face, eliminating the need for heavy rigid frames while maintaining secure positioning and sealing of the nasal pillow.

Inventive Principle:
Principle #30Flexible shells and thin films

2Reliability

If a complex assembly structure with multiple components is used, then the stability and functionality are improved, but the ease of use deteriorates due to assembly complexity

Engineering Contradiction:
ImprovestabilityVSAvoidease of use
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent integrates multiple components into a unified headgear assembly where the flexible band, soft contact surface, and nasal pillow support structure are combined into a single cohesive unit. This merging of components maintains the stability and functionality needed for secure nasal pillow positioning while eliminating complex assembly steps, allowing users to simply don the headgear without tools or complicated procedures.

Inventive Principle:
Principle #5Merging (Combining)

3Weight of moving object

If a lightweight design is used to improve comfort, then the weight is reduced, but the stability deteriorates causing the tube to fall off or leak

Engineering Contradiction:
ImproveweightVSAvoidstability
Core Design Contradiction:
Weight of moving objectVSReliability

Solution Approach 1:

The patent employs a dynamic headgear system with adjustable elastic bands that adapt to user movements and facial contours. The flexible band incorporates tensioning mechanisms that automatically adjust to maintain optimal securing force during sleep, ensuring the nasal pillow remains stable and leak-free throughout the night while keeping the overall weight minimal for comfort.

Inventive Principle:
Principle #15Dynamics

AI summary

A frame assembly directly connected to a frame and a short tube, including a frame and a gas delivery hose and side connectors connected to the frame. The frame is configured to bend towards the face. The frame includes a fixed opening and first connection parts connected to the side connectors. The gas delivery hose includes a first end, a middle hose, and a second end. The side connectors have a front end and a rear end. The front end is for connecting to the frame, the rear end to the face. The frame assembly directly connected to a frame and a short tube also includes an exhaust channel, located on the frame or the gas delivery hose. The frame is detachably connected directly to the gas delivery hose. Combining the exhaust channel with the frame or gas delivery hose reduces the noise and lightens the weight by reducing parts, enhancing the comfort and user experience.
