Pivoting Eye Protector Assembly with Nested Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ear-engaging and eye-covering head assemblies are prone to damage, lack protection for glasses, and require a visor, making them less compact and robust.
Innovation Solution
A head assembly with an arcuate-shaped protective cover that includes a pivotably connected eye protector and connector mechanisms for coupling with a hearing protector, featuring inwardly-extending protrusions and slots for secure attachment to a headband, providing protection for both eyes and ears while allowing the eye protector to be stored within the cover when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the eye protector is left exposed on the head assembly, then it is easily accessible for use, but it is vulnerable to damage from scratching, stepping on, or impact
Solution Approach 1:
The eye protector is designed to be received within the protective cover when not in use, creating a nested configuration where the smaller eye protector component is housed inside the larger protective cover structure. This nesting arrangement protects the eye protector from damage while maintaining easy accessibility when needed.
2Reliability
If the eye protector is integrated permanently with the head assembly, then it is always protected, but the overall device size increases and it cannot be stored compactly
Solution Approach 1:
The eye protector is made movable relative to the protective cover through a pivot connection, allowing it to transition between an extended operational position and a retracted stored position within the cover. This dynamic arrangement enables the assembly to maintain a compact form when the eye protector is not in use, while still providing protection when needed.
3Reliability
If connector mechanisms are added to couple the protective cover with the hearing protector, then the assembly becomes more robust, but the device complexity increases
Solution Approach 1:
The connection system is divided into discrete connector mechanisms that can be selectively engaged with the hearing protector headband. These segmented connectors are positioned at specific locations on the protective cover, allowing for modular assembly and disassembly while maintaining a robust connection when engaged.
4Reliability
If the protective cover is designed to receive the eye protector within it, then the eye protector is protected from damage, but the cover requires additional structural features increasing its complexity
Solution Approach 1:
The protective cover is designed with an internal receptacle space that receives the eye protector, creating a nested configuration. The cover's structure includes opening and closing features that allow the eye protector to be inserted and secured within the protective enclosure, providing comprehensive protection while maintaining a relatively simple overall structure.

AI summary
The present invention relates to an eye-protector assembly. The assembly includes arcuate-shaped protective cover. The assembly includes an eye-covering member pivotably connected to the protective cover. The protective cover is shaped to receive the eye-covering member when the eye-covering member is pivoted towards the cover. The assembly includes a pair of connector mechanisms for selectively coupling the protective cover to a hearing protector.
