Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional CPAP devices and mandibular splint devices are used to treat OSA, then airway pressure support is provided, but the devices are invasive and only marginally effective
Solution Approach 1:
The device divides the nasal cavity treatment into two separate components (first component for one nostril, second component for the other nostril), each independently managing airflow and pressure. This segmentation allows for less invasive treatment compared to full-face masks while maintaining therapeutic effectiveness through localized positive pressure application in each nasal passage
Solution Approach 2:
The device applies positive expiratory airway pressure locally at the nasal passage level rather than systemically. Each component's valve mechanism and loop structure are specifically designed to create localized pressure zones within the nasal cavity, providing targeted therapy that is both effective and comfortable without the invasiveness of traditional CPAP systems
2Object-affected harmful factors
If nasal devices are designed to be less invasive, then patient comfort is improved, but effectiveness in managing airway pressure may be reduced
Solution Approach 1:
The valve mechanism in each component dynamically responds to breathing cycles, automatically opening during inspiration to allow airflow and closing during expiration to trap air and generate positive pressure. This dynamic operation ensures effective pressure management without requiring invasive fixation, as the device adapts to natural breathing movements while maintaining therapeutic pressure levels
Solution Approach 2:
The device utilizes the patient's own breathing efforts to generate the required positive airway pressure. The valve mechanism is designed to work passively with the patient's natural respiratory cycle, eliminating the need for external power sources or complex mechanical systems. This self-service approach enhances patient comfort while maintaining treatment effectiveness through bio-mechanical synergy
3Adaptability or versatility
If nasal devices include integrated sensors and conduits for data collection and fluid delivery, then diagnostic and therapeutic capabilities are enhanced, but device complexity increases
Solution Approach 1:
Each component is designed as a multi-functional unit that simultaneously provides structural support (loop structure), airflow control (valve mechanism), sensor mounting (mounts), and fluid delivery (conduit apertures). This universal design consolidates multiple functions into integrated components rather than separate attachments, enhancing versatility while managing complexity through functional integration at the component level
Solution Approach 2:
The device employs a nested structure where conduits and sensors are integrated within or upon the component bodies. The mount structures provide platforms for attaching additional elements, creating a hierarchical arrangement where simpler elements are nested within or attached to more complex structures. This nesting approach allows for enhanced functionality while organizing complexity in a manageable, modular fashion
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 device effectively manages airway pressure, improves sleep quality by reducing apnea events, and provides data for diagnosis, with potential for improved patient comfort and tolerance through customizable resistance and material variations.
Implementation Method 1
a valve mechanism disposed on the platform for controlling fluid flow through the aperture
Implementation Method 2
The valve mechanism may comprise a seal spanning the aperture defined by the inner surface of the loop structure, wherein the seal includes a valve configured to transition between an open state, whereby fluid may be conveyed through the platform, and a closed state, whereby fluid may be hindered from being conveyed through the platform by the valve

AI summary
A nasal device comprises a first component and a second component and a connector for coupling the first component to the second component and configured to span a nasal septum of the user. The first component comprises a body for insertion into a nasal cavity of a nose of a user. The body comprises a loop structure having an inner surface defining an aperture and a reverse outer surface, the loop structure being configured for alignment with an interior contour of a nasal passage of the nose, a platform spanning the aperture defined by the inner surface of the loop structure, and a valve mechanism disposed on the platform for controlling fluid flow through the aperture. The first component further comprises at least one mount extending from the body.
