Swivelling Disc Cable Management for Respiratory Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current respiratory therapy devices for conditions like Obstructive Sleep Apnea and Chronic Obstructive Pulmonary Disease face challenges with uncomfortable and poorly fitting masks, leading to reduced patient compliance due to discomfort and difficulty in use, especially during extended wear or sleep.
Innovation Solution
A respiratory therapy system with a patient interface that includes a seal-forming structure with a flexible, resilient material and a positioning and stabilizing structure, such as nasal pillows or a full-face mask, designed to provide a secure and comfortable fit, along with a humidifier to prevent airway drying and improve comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mask is designed to provide a secure fit for respiratory therapy, then treatment effectiveness is improved, but patient comfort deteriorates leading to reduced compliance
Solution Approach 1:
The mask is divided into multiple independent components including a headgear system with separate adjustment mechanisms, a cushion section, and a frame structure. This segmentation allows each component to be optimized independently for both secure fitting and comfort, resolving the contradiction between treatment effectiveness and patient comfort.
Solution Approach 2:
The headgear system incorporates dynamic adjustment mechanisms that allow the mask to adapt to different patient head sizes and shapes. The adjustable straps and flexible components enable the mask to maintain a secure seal for effective treatment while accommodating individual comfort requirements, thus resolving the contradiction between reliability and ease of operation.
2Duration of action of moving object
If a mask is designed for extended wear during sleep, then treatment coverage is improved, but discomfort increases leading to reduced compliance
Solution Approach 1:
The cushion material parameters are specifically selected to provide both adequate seal pressure for effective treatment and sufficient softness for extended comfort during sleep. The material density, elasticity, and thickness are optimized to maintain treatment coverage throughout the night while preventing discomfort that would reduce compliance.
3Reliability
If a mask provides a secure seal for effective therapy, then treatment reliability is improved, but difficulty in use increases
Solution Approach 1:
The mask design incorporates self-adjusting features that allow patients to easily achieve a proper seal without requiring assistance or complex adjustment procedures. The automatic sealing mechanisms and intuitive strap system enable patients to independently configure the mask for both effective treatment and comfort, resolving the contradiction between reliability and ease of use.
