Adjustable Face Rest for Uniform Pressure Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Face cover devices, such as goggles and masks, often fail to provide a uniform fit across different face shapes, leading to discomfort and compromised sealing, which can result in pressure points and impaired functionality.
Innovation Solution
The face cover device features a face rest part with adjustable connecting sections that allow for independent adjustment relative to the functional part, ensuring a tight fit and uniform pressure distribution, thereby accommodating various face shapes and enhancing both comfort and sealing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a face cover device has a given specific shape, then the device structure is simple and easy to manufacture, but it cannot fit every user's face shape and provides non-uniform pressure distribution
Solution Approach 1:
The face cover device is divided into a functional part and a face rest part that can be adjusted independently. The face rest part includes multiple adjustment positions that allow segmentation of the fitting areas, enabling adaptation to different face shapes while maintaining a relatively simple overall structure.
Solution Approach 2:
The connecting sections are made adjustable with multiple positions, transforming the device from a static structure to a dynamic one that can adapt to different users. This allows the same device to provide customized fitting for various face shapes without requiring multiple different device designs.
2Reliability
If the face cover device is adjusted to fit different face shapes, then wearing comfort and sealing are improved, but the device complexity increases due to multiple adjustment mechanisms
Solution Approach 1:
The adjustment mechanism is segmented into discrete connecting sections with specific adjustment positions, rather than using continuous complex mechanisms. This segmentation provides reliable sealing at each position while keeping the adjustment mechanism simple and manageable.
Solution Approach 2:
Different connecting sections are provided with different adjustment positions tailored to specific face areas (temples, cheeks, forehead, nose, chin). This local customization ensures reliable sealing where needed without requiring complex adjustments throughout the entire device.
3Ease of operation
If the face rest part is made flexible to adapt to face shape, then pressure distribution is improved, but the structural stability and positioning precision are reduced
Solution Approach 1:
The face rest part combines flexible material with discrete adjustment positions. The flexibility allows the material to conform to the face shape for comfort, while the fixed adjustment positions provide precise positioning and stable structure when the device is configured for a specific user.
Solution Approach 2:
The face rest part is constructed from flexible material that can deform to match the contours of the user's face, improving comfort and pressure distribution. This flexibility is combined with structured connecting sections that maintain positioning precision through defined adjustment positions.
