Retrofittable Chin Protector for Clear-View Face Shields
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chin protectors integrated with protective face shields limit flexibility in size, shape, and material selection, and can obstruct the wearer's view, necessitating a solution that provides protection while maintaining clear visibility and allowing for independent selection and easy attachment.
Innovation Solution
A chin protector that can be bent from a planar to a curved configuration for attachment to a protective face shield, offering releasable or non-releasable attachment options, and made from materials like polymeric materials, metals, or glass, with attachment means such as pins and receptacles for secure fitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the chin protector is integrally molded with the protective face shield, then the viewing conditions are improved and the structure is simplified, but the flexibility in size, shape, and material selection is limited
Solution Approach 1:
The chin protector is separated from the face shield into an independent detachable component. This segmentation allows the chin protector to be selected and attached independently based on specific needs for size, shape, and material, while maintaining good viewing conditions when properly positioned.
Solution Approach 2:
The chin protector incorporates a flexible planar configuration that can be bent into a curved shape for attachment. This dynamic flexibility allows the same component to adapt to different face shield configurations and provide optimal viewing conditions while maintaining attachment flexibility.
2Adaptability or versatility
If the chin protector is attached by gluing or connection elements, then the flexibility in selection is improved, but the attachment complexity increases
Solution Approach 1:
The attachment function is merged with the chin protector structure itself through the flexible planar configuration that naturally conforms to the curved surface of the face shield. This eliminates the need for separate connection elements or complex attachment mechanisms, reducing overall device complexity while maintaining flexibility.
3Reliability
If the chin protector is fixed to the face shield, then the reliability of protection is improved, but the ease of replacement is worsened
Solution Approach 1:
The chin protector uses a dynamic flexible configuration that can be easily attached and detached while maintaining reliable protection when in place. The flexibility allows for simple attachment/removal operations while the curved configuration ensures consistent protective positioning during use.
