Bendable Detachable Chin Protector for Clear Face Shield Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chin protectors integrated with protective face shields can obstruct the wearer's view and limit flexibility in size, shape, and material selection, while being difficult to replace or retrofit.
Innovation Solution
A detachable chin protector that can be bent from a planar to a curved configuration for easy attachment to a protective face shield or helmet, allowing independent selection and replacement based on wearer needs, with optional attachment means like pins and receptacles for secure fitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If chin protectors are integrally molded with protective face shields, then viewing conditions are improved, but flexibility in size, shape, and material selection is limited
Solution Approach 1:
The chin protector is separated from the face shield, allowing independent selection and attachment of different chin protector types while maintaining clear viewing through the face shield. Users can choose from various sizes, shapes, and materials without being constrained by integral molding.
Solution Approach 2:
Attachment means serve as an intermediary between the chin protector and face shield, enabling flexible connection while maintaining optical clarity. The attachment mechanism allows the chin protector to be positioned optimally for both protection and viewing conditions.
2Object-affected harmful factors
If chin protectors are attached to protective face shields, then protection against spatter and radiation is improved, but view obstruction increases
Solution Approach 1:
The protective system is divided into separate components: the face shield provides clear viewing while the detachable chin protector provides protection against spatter and radiation. This segmentation allows each component to be optimized for its specific function without compromising the other.
Solution Approach 2:
Different parts of the protective system have different properties: the face shield is transparent for viewing, while the chin protector is positioned to provide localized protection where needed. The attachment means enable precise positioning to minimize view obstruction while maximizing protection.
3Ease of operation
If chin protectors are made as part of a strap assembly, then ease of operation is improved, but adaptability to different face shields is reduced
Solution Approach 1:
The chin protector with attachment means is designed to be universally compatible with different face shield types. The attachment mechanism can accommodate various face shield configurations, allowing the same chin protector to be used across multiple face shield models while maintaining ease of operation.
4Reliability
If chin protectors are attached using gluing or connection elements, then reliability of attachment is improved, but ease of repair and replacement is worsened
Solution Approach 1:
The attachment means provide a dynamic balance between secure attachment and easy release. The mechanism maintains reliable attachment during use but allows for simple removal and replacement when needed, enabling both high reliability and ease of repair.
Solution Approach 2:
The detachable attachment system allows chin protectors to be easily removed, replaced, or recovered for maintenance. Users can discard damaged protectors and attach new ones without complex procedures, while the attachment means ensure secure attachment during normal use.
