Rotating Face Cover Assembly for PPE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal protective equipment (PPE) for infectious diseases, such as biohazard suits and facemasks, are often uncomfortable due to a one-size-fits-all design, causing binding and fogging issues, and lack versatility for users with varying facial structures and needs.
Innovation Solution
A PPE device featuring a rotating face cover assembly with multiple mask sides and a zip-up bodysuit, allowing users to select the most comfortable and suitable configuration based on their facial geometry and activities, with adjustable mechanisms and optional features like microbial filters and air supply systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a one-size-fits-all face mask design is used, then manufacturing simplicity is improved, but comfort and fit for users with varying facial structures deteriorates
Solution Approach 1:
The face mask is divided into multiple interchangeable sides, each with different geometric configurations (e.g., flat, contoured, indented). Users can select and attach the side that best fits their facial structure, maintaining manufacturing simplicity while improving comfort and fit for diverse users.
Solution Approach 2:
The mask incorporates adjustable and reconfigurable elements such as adjustable straps, movable sides, and adaptable sealing mechanisms that allow users to dynamically adjust the mask to their facial geometry, enhancing comfort without complicating the basic manufacturing process.
2Reliability
If a tight-fitting face mask is used, then protection against airborne pathogens is improved, but comfort during prolonged use deteriorates
Solution Approach 1:
Different sides of the mask provide different levels of tightness and coverage in specific regions. For example, one side may have a tighter seal around the nose and mouth for maximum protection, while another side offers a more relaxed fit for comfort during extended wear. Users can switch between sides based on their specific needs and comfort levels.
3Ease of operation
If a face shield is used, then comfort during prolonged use is improved, but moisture trapping and fogging deteriorates
Solution Approach 1:
The mask is divided into multiple sides with different designs. One side may feature a more open structure with larger spacing or ventilation areas that reduces moisture trapping and fogging, while another side provides tighter coverage for maximum protection. Users can switch to the more open side when experiencing fogging issues.
4Adaptability or versatility
If multiple face mask configurations are provided, then adaptability to different users and scenarios is improved, but device complexity deteriorates
Solution Approach 1:
The mask is designed as a universal multi-functional device with multiple sides that can be attached to the same base structure. This allows one mask to serve multiple functions and accommodate different users and scenarios without requiring completely separate masks for each configuration, thereby limiting the increase in overall complexity.

AI summary
A personal protective device (PPE) including a face cover assembly and a bodysuit configured to be worn by a human user. The device protects users against airborne aerosol particles containing viruses or other infectious agents while enabling improved flexibility relative to prior art designs. The device includes a helmet-like” rotating face cover assembly that fits over the user's head and attaches to a collar on the biohazard bodysuit. This rotating face cover assembly has a plurality of different mask sides, each with differing geometries or other properties. The device enables a user to can rotate the cover and select a given mask side that best meets that user's needs. The different mask sides can accommodate different facial geometries, eyewear types, and use cases.
