Respiratory Mask Nose Support Extension Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing respiratory protection devices often compromise between sealing and comfort, particularly in the nose region, where they may interfere with eyewear and other personal protective equipment due to bulkiness and thickness, and struggle to provide adequate support without increasing unnecessary thickness.
Innovation Solution
A respiratory mask design featuring a nose region with a seal and a support extension that extends away from the seal, providing additional support without increasing the overall thickness, allowing the seal to be thinner and more comfortable, especially in the nose area, while maintaining effective sealing and compatibility with eyewear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the seal is made thicker to provide adequate support in the nose region, then support and stability are improved, but comfort deteriorates and compatibility with eyewear is reduced
Solution Approach 1:
The mask is divided into two functional components in the nose region: a seal for sealing and a separate support extension for support. This segmentation allows each component to be optimized independently - the seal can be thin for comfort while the support extension provides the necessary structural support without interfering with eyewear.
Solution Approach 2:
The support function is extracted from the seal and placed into a separate support extension structure. This extraction allows the seal to be made thinner and more comfortable while the support extension independently provides the necessary structural support, resolving the contradiction between support and comfort.
2Strength
If the seal is made thicker to provide adequate support, then support and stability are improved, but compatibility with eyewear deteriorates
Solution Approach 1:
By segmenting the seal and support functions into separate components, the design allows the seal to remain thin for eyewear compatibility while the support extension independently provides structural support, enabling simultaneous achievement of both compatibility and support.
Solution Approach 2:
The support function is extracted from the seal structure and placed into a separate support extension. This extraction enables the seal to be optimized for eyewear compatibility with minimal thickness while the support extension separately provides the necessary structural support.
3Strength
If a rolled edge is used in the nose region to provide support, then support and sealing are improved, but thickness and bulkiness increase
Solution Approach 1:
The support function is segmented from the sealing function, with the support extension providing support without requiring a rolled edge structure. This eliminates the need for thick rolled edges in the nose region while maintaining support functionality.
Solution Approach 2:
The rolled edge structure is extracted from the nose region design, replacing it with a support extension that provides support without the thickness and bulkiness associated with rolled edges, while maintaining effective support and sealing.

AI summary
A respiratory mask body having a nose region including a seal and a support extension is provided. In an exemplary embodiment, the mask body has a nose region including a support extension which extends in a direction away from the seal and is configured to contact a user's nose at a position beyond the seal.
