Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Protective masks for skiing disciplines face challenges in achieving an optimal fit and seal in the nasal region due to varying facial morphologies and curvatures, which are difficult to accommodate in the limited nasal area.
Innovation Solution
A protective mask with a nasal support and bearing element featuring rotatable appendages and a snap-type adjustment mechanism using interlocking teeth, allowing for customizable fit and alignment with the nasal region's shape, ensuring secure and comfortable contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed nasal support element is used, then the mask structure is simple, but the fit and seal in the nasal region deteriorate due to varying facial morphologies
Solution Approach 1:
The nasal support element is designed with rotatable appendages that can be adjusted to different angular positions, transforming a static structure into a dynamic one that adapts to various nasal morphologies and curvatures while maintaining an acceptable level of structural complexity
Solution Approach 2:
The nasal support element is divided into multiple independent appendages (first and second appendages) that can be adjusted separately, allowing each segment to adapt to the specific contours of the nasal region while keeping the overall device complexity manageable
2Adaptability or versatility
If the nasal support element is made adjustable to accommodate different facial morphologies, then the fit and seal improve, but the device complexity increases
Solution Approach 1:
Adjustability is implemented only in the nasal support region where it is most needed, rather than throughout the entire mask structure. The appendages can be rotated independently to match local nasal contours, providing high adaptability where required while keeping the rest of the mask structure simple and unified
Solution Approach 2:
The rotatable appendages with locking mechanisms provide dynamic adjustment capability localized to the nasal region, enabling morphological adaptation without requiring the entire mask structure to be complex or adjustable
3Adaptability or versatility
If the nasal support element is made more complex to accommodate accentuated morphological differences, then the adaptability improves, but the ease of manufacture deteriorates
Solution Approach 1:
The solution uses a mechanical rotation and locking mechanism that, while providing complex adaptability, relies on standard manufacturing techniques for rotating components and locking features, avoiding the need for highly complex or custom manufacturing processes
Solution Approach 2:
By dividing the nasal support into separate appendages with individual adjustment mechanisms, each component can be manufactured independently using standard processes, and then assembled, which simplifies manufacturing compared to creating a single complex adjustable structure
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 mask achieves a precise and homogeneous fit and seal in the nasal region, enhancing comfort and protection across different facial morphologies by allowing adjustable alignment and curvature adaptation.
Implementation Method 1
A resilient strap, indicated by 5, having respective ends 5a, 5b secured to respective laterally opposed portions of the front frame. A mechanism for adjusting the length and consequent tensioning of the resilient strap, of conventional type per se, is provided on the resilient strap 5
Implementation Method 2
Said means comprise a pair of appendages, both indicated by 8, mounted to be rotatable on a frame portion 2a extending in the region of the nasal support element 6, about respective axes of rotation (X, X′)

AI summary
A protective mask for sports use that includes a front frame for the retention of at least one lens, a nasal support element, the fit of the nasal support element being adjusted, by adaptation of the frame to the shape of the face in the nasal support region. The support element is structurally independent of the front frame and at least one appendage is mounted to be rotatable on the front frame, at the nasal support region, about an axis of rotation and also acting on the nasal support element, in order to displace the support relative to the front frame, the at least one appendage being reversibly locked in a selected angular position relative to the frame, about the axis, so as to improve the adaptation of the nasal support element to the shape of the nasal region of the face.
