Solution Overview

Problem

Existing nasal dilators face issues such as adhesion loss, skin irritation, and discomfort due to repeated impact on the nasal passages, which can lead to snoring, sleep apnea, and reduced airflow.

Innovation Solution

A nasal dilation system featuring multiple sets of nasal dilators with distinct patterns of interconnected struts and openings, designed to engage differently with the inner nasal surface, reducing repeated impact and promoting airflow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If internal nasal dilators are used to push open nostrils, then airflow is improved, but repeated impact on the internal nasal surface causes discomfort and health issues such as chaffing, follicle infection, and in-growing nasal hairs

Engineering Contradiction:

ImproveairflowVSAvoiddiscomfort and health issues

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The nasal dilator is divided into multiple sets, each with a unique strut pattern. This segmentation allows different portions of the mesh wall to contact different areas of the nasal passage across multiple uses, distributing the impact and preventing concentrated repeated trauma to the same location.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each set of nasal dilators has a specific localized pattern of struts and openings that creates a unique impact distribution. By cycling through multiple sets with different local patterns, the contact points on the nasal surface vary, preventing chronic irritation at any single location while maintaining the overall airflow-opening function.

Inventive Principle:

Principle #3Local quality

2Productivity

If external nasal dilators are used to pull open nostrils, then airflow is improved, but adhesion is lost when the user sweats or moves during sleep

Engineering Contradiction:

ImproveairflowVSAvoidadhesion

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The invention extracts the dilator from the external environment and places it internally, eliminating the need for adhesive attachment. The internal dilator relies on mechanical engagement with the nasal passage structure rather than chemical adhesion, so sweating or movement does not cause loss of attachment.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of operation

If a single set of nasal dilators is used continuously, then the structure becomes familiar and easy to use, but repeated impact on the same inner surface portion causes health issues

Engineering Contradiction:

Improveease of useVSAvoidrepeated impact damage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Multiple sets of nasal dilators are combined into a single system, where each set has a slightly different pattern but serves the same function. This merging allows the user to cycle through different patterns, distributing the mechanical impact across various areas of the nasal passage while maintaining ease of use through consistent overall design and instruction.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A nasal dilation system has at least two sets of nasal dilators. Each set includes one or more nasal inserts having a mesh wall comprised of interconnected struts and openings. The mesh wall forms a cannula. The inserts are designed to engage with the inner surface of nasal passages. The pattern of struts and openings of a first set differs from a second set, resulting in different impact patterns on the inner surface of nasal passages, reducing repeated impact of the same inner surface portion across multiple sets of nasal dilators.
