Face Shield Head Covering Adjustable Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional face masks often fit too loosely or too tightly, leading to discomfort and increased risk of touching the mask, which can compromise their effectiveness in preventing airborne contamination.
Innovation Solution
A face protection system that includes a head covering with an adjustable attachment element allowing the face shield to transition between positions, redistributing pressure and enhancing fit, thereby improving comfort and reducing unfiltered air intake.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional face mask is made secure enough to stay in place, then the mask remains effective in preventing airborne contamination, but the mask becomes too tight causing discomfort and increasing the risk of touching the mask
Solution Approach 1:
The face protection system is divided into two separate components: a head covering that provides structural support and distribution of force, and a face mask that provides filtration. The head covering absorbs the securing function, allowing the face mask to remain loose and comfortable while still being held securely against the face through the attachment elements on the head covering.
2Ease of operation
If a conventional face mask is made loose to improve comfort, then the mask becomes easier to wear, but the mask fails to stay in place and allows unfiltered air intake
Solution Approach 1:
The system separates the securing function (head covering with attachment elements) from the filtration function (face mask). This allows the face mask to be loose and comfortable while the head covering ensures it stays in place through adjustable attachment elements that secure the mask to the head covering rather than relying on tight elastic bands.
3Reliability
If elastic bands are used to secure the face mask, then the mask stays in place, but pressure is concentrated on the ears, back of the head, and neck causing discomfort
Solution Approach 1:
The head covering acts as an intermediate structure that distributes the securing function across a larger area of the head. The attachment elements on the head covering connect to the face mask, distributing pressure away from sensitive areas like ears and neck, and spreading it across the broader surface area of the head covering.
Solution Approach 2:
The head covering serves as an intermediary between the face mask and the user's head. Instead of elastic bands directly contacting and pressing on the ears and neck, the head covering mediates this interaction, providing a larger surface area that distributes pressure more evenly across the head.
4Reliability
If the face mask fit is made adjustable to improve coverage, then unfiltered air intake is reduced, but the device complexity increases
Solution Approach 1:
The head covering serves multiple functions: it provides structural support, distributes pressure, and offers adjustable attachment elements for securing the face mask. The attachment elements can be adjusted to different positions on the head covering to accommodate different head sizes and shapes, providing a universal solution that works for various users without requiring complex adjustment mechanisms on the face mask itself.

AI summary
A face shield and head covering combination is provided. The head covering comprises a body and an attachment element. The body defines a head opening configured to receive a user's head therethrough. The attachment element is coupled to the body and configured to couple to a face shield positionable on the user's face. The attachment element is configured to transition between a first position on the body and a second position on the body, wherein the second position is spaced from the first position.
