Removable Headgear Connector for CPAP Mask Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mask systems for treating Sleep Disordered Breathing (SDB) are limited by the need for specific headgear designs that are incompatible with different mask frames, leading to reduced patient comfort, fit issues, and decreased compliance with therapy.
Innovation Solution
A mask system with a common frame that can be adapted for use with various headgear styles, featuring interchangeable headgear connectors that attach to the frame without built-in attachment points, allowing for multiple headgear configurations to be used with a single frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mask frame is designed with built-in headgear attachment points, then the structural integrity and sealing are improved, but the adaptability to different headgear styles is reduced
Solution Approach 1:
The headgear attachment system is segmented into separate removable connectors that can be independently selected and attached to the frame, rather than being integrated into the frame structure. This allows different connector types to be used with the same frame, improving adaptability without increasing frame complexity.
Solution Approach 2:
The frame is designed with a universal attachment interface that can accommodate multiple types of headgear connectors. The common frame structure serves multiple functions by supporting various connector configurations, enabling compatibility with different headgear styles while maintaining structural integrity.
2Ease of operation
If multiple specific headgear designs are created for different mask frames, then the fit and comfort for specific patients are improved, but the device complexity and inventory requirements increase
Solution Approach 1:
A single common frame design serves multiple patients and applications by supporting various removable headgear connectors. This universal frame reduces the need to manufacture multiple frame variants while still providing customized fit options through different connector selections.
Solution Approach 2:
The headgear system becomes dynamic and reconfigurable, allowing the attachment points and connector types to be changed based on patient needs. This flexibility enables optimal fit and comfort adjustments without requiring multiple fixed frame designs.
3Adaptability or versatility
If headgear connectors are made removable and interchangeable, then the adaptability and patient selection options are improved, but the reliability of the connection may be reduced
Solution Approach 1:
The connection system is divided into modular components (frame interface, connector, headgear) that can be independently optimized. Each segment can be designed for reliable connection while maintaining interchangeability, with standardized interfaces ensuring consistent performance across different configurations.

AI summary
A mask for delivering breathable gas to a patient at positive pressure to treat sleep disordered breathing, may comprise: a rigid mask frame having a bore and an interfacing structure, the interfacing structure being located on the rigid mask frame and along a peripheral edge of the bore, said mask frame having no built-in or integral headgear attachment points; a sealing cushion provided to the rigid mask frame and adapted to form a seal with the patient's face, the rigid mask frame and the sealing cushion together forming, at least partly, a breathing cavity; and a headgear connector adapted to engage the interfacing structure with a snap-fit, said headgear connector including a pair of lower headgear clip anchors adapted to be engaged with respective ones of a pair of lower headgear clips to attach a pair of lower side straps, said headgear connector including a fixed forehead support.
