Mask Side Fixing Portion for Ear Stress Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional masks suffer from issues such as discomfort due to ear stress, skin irritation, incomplete sealing leading to fogging, and difficulty in maintaining tight contact with the face, especially when facial muscles move, which results in increased leakage rates and reduced wearing comfort.
Innovation Solution
A mask design featuring a frame unit with a pressing portion that securely contacts specific facial regions, including the nose and peripheral areas, to maintain tight contact without strong pressure, using adjustable coupling portions to optimize fit and reduce leakage, and incorporating a pressing portion to prevent fogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional masks use ear strings to fix the mask, then the mask can be secured to the face, but ear stress and discomfort increase during prolonged wearing
Solution Approach 1:
The invention extracts the fixation function from the ear strings and relocates it to the side fixing portions that contact the cheeks. The ear strings are reduced to auxiliary elements, while the primary fixation is achieved through the side fixing portions with pressing portions that engage with the cheekbones and jaw area, thereby eliminating ear stress while maintaining reliable mask fixation
Solution Approach 2:
The side fixing portions act as intermediary elements between the mask body and the face. Instead of directly hanging from ears, the mask is mediated through side fixing portions that contact the cheeks and are secured by pressing portions, distributing the fixation force across a different anatomical region and eliminating the harmful ear stress
2Reliability
If the mask presses the nose and mouth region to seal, then leakage is reduced, but skin irritation and discomfort increase
Solution Approach 1:
The pressing portions are designed with localized contact points that apply pressure only to specific bony structures (cheekbones, jaw area) rather than distributing pressure across soft skin areas. This local quality approach maintains sealing effectiveness at critical points while avoiding irritation to sensitive skin regions
Solution Approach 2:
The pressing portions are designed with curved surfaces that conform to the natural contours of the cheekbones and jaw. This curvature allows for even pressure distribution across the contact area, preventing concentration of force that would cause skin irritation while maintaining effective sealing
3Ease of operation
If the mask uses loose fitting to reduce pressure, then comfort is improved, but leakage increases and fogging occurs
Solution Approach 1:
The side fixing portions are designed to be dynamically adjustable, allowing users to modify the pressing force according to their comfort needs. The elastic components enable the fixation strength to adapt during wearing, maintaining both comfort and sealing effectiveness through flexible adjustment rather than fixed rigid pressure

AI summary
Disclosed is a novel mask including a fixing portion that is not fixed to ears but is brought into tight contact with a specific region of a face so as to fix the mask to the face and a nose pressing portion that securely seals the peripheral portion of a nose without pressing the face of a user, unlike a conventional mask.
