Spring Wire Spectacle Frame Mount for Gas Mask Seal Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spectacle frame mounts for gas masks and full-face respirators do not provide sufficient stability for eyeglasses during strenuous activities, leading to potential vision impairment due to shifting or dislodgment of lenses.
Innovation Solution
A spectacle frame mount using a resilient spring wire configuration, either as a cage or base clamp, that securely positions eyeglasses within the full-face mask without compromising the seal integrity, utilizing a self-tensioning mechanism to maintain alignment and prevent dislodgment during rough usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional eyeglasses with side pieces are worn under a full face mask, then the user can maintain vision correction, but the side pieces compromise the seal integrity of the facepiece
Solution Approach 1:
The invention extracts the side pieces from the eyeglass assembly, creating a modified eyeglass frame without side pieces that can be worn under the full face mask without compromising the seal. The side pieces are completely removed rather than modified, allowing the facepiece to maintain positive contact with the wearer's face while still providing vision correction through the front lenses.
Solution Approach 2:
The invention nests the modified eyeglass frame within the full face mask interior, positioning the frame and lenses inside the sealed environment created by the facepiece. This nesting arrangement allows the eyeglasses to function for vision correction while remaining contained within the sealed space, preventing any interference with the external seal.
2Stability of the object's composition
If a spectacle holding device is secured in the channel between the wraparound lens and facepiece, then the eyeglasses can be positioned, but the device does not provide sufficient stability during strenuous activities
Solution Approach 1:
The invention employs a dynamic spring-loaded mounting mechanism that automatically adjusts to maintain stable positioning of the eyeglasses during movement and strenuous activities. The spring element provides continuous adaptive pressure against the eyeglass frame, ensuring stable positioning without requiring complex mechanical adjustments or multiple components.
Solution Approach 2:
The spring-loaded mounting device is designed to be self-adjusting and self-regulating, automatically maintaining proper eyeglass positioning through the elastic properties of the spring element. The system serves itself by using the spring's natural expansion and contraction to compensate for movement and maintain stable contact pressure without external intervention or complex control mechanisms.
3Reliability
If the spectacle frame shifts or dislodges, then the mounting mechanism fails, but maintaining secure positioning may compromise the seal against the wearer's face
Solution Approach 1:
The invention applies local quality by creating a dedicated mounting location within the full face mask interior that is specifically designed to hold eyeglasses securely without interfering with the seal. The spring-loaded device is positioned in a localized area that does not contact the seal interface, allowing secure eyeglass retention while maintaining the integrity of the facepiece-to-face seal in other critical areas.
Solution Approach 2:
The spring-loaded mounting device acts as an intermediary element between the eyeglasses and the full face mask interior. It provides secure retention of the eyeglasses through spring pressure while being contained within the sealed environment, preventing direct contact between the mounting mechanism and the external seal interface, thus avoiding seal compromise.
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 solution provides a stable and secure positioning of eyeglasses, ensuring proper vision alignment even during strenuous activities, while maintaining the seal integrity of the gas mask or respirator, thus preventing air ingress or egress.
Implementation Method 1
a spectacle frame mount which is removably positionable in a gas mask or full face respirator... configured with a spring wire support structure that is adapted to form a spring-biased, retentive fit within a full face covering mask

AI summary
A spectacle frame mount provides secure, removable positioning of a spectacle frame in a gas mask or full face respirator. A spring wire mount supports the spectacle frame between two legs of a loop. The spring wire mount includes two leg portions that have lower ends which terminate adjacent each other when the mount is in its use position. The two leg portions positively engage an internal portion of the full face mask so that the spectacle frame will be positioned within the interior of the mask at a location such that the spectacles will be properly positioned for use by the person wearing the mask.
