Protective Eyewear Swivel Clip Strap Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective eyewear for female lacrosse and field hockey players is uncomfortable and poorly secured, often causing glare, fogging, and vision obstruction due to bulky designs and elastic straps that do not accommodate hair styles like ponytails effectively.
Innovation Solution
A protective eyewear system featuring a foldable strap with aligned openings and a swivel clip mechanism that allows for adjustable and secure fitting around the head, accommodating hair styles and providing comfortable wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional elastic straps are used to secure goggles, then the goggles can be held in place, but the strap pulls the goggles upward or downward on the player's face and can slide off the head
Solution Approach 1:
The strap system is divided into multiple functional segments: a non-elastic head retention strap that prevents sliding off, and an elastic lower strap that provides securement without excessive pulling force. This segmentation allows each part to perform its specific function optimally.
Solution Approach 2:
The strap system incorporates dynamic elements including an elastic portion that flexes with movement, a swivel clip that rotates to accommodate different head positions and hair styles, and adjustable length configuration. This dynamic design adapts to the player's movements and anatomy.
2Strength
If caged or bulky goggles are used for protection, then eye protection is provided, but vision is impeded and the goggles are easily scratched or shattered
Solution Approach 1:
The patent employs a thin, flexible polycarbonate shield that provides eye protection without the bulk of traditional cages. This thin-film approach maintains vision clarity while offering sufficient protection against impacts from balls and sticks.
Solution Approach 2:
The goggle construction uses composite materials including polycarbonate for the main shield and frame, combining durability with light weight. The material selection balances protection strength with optical clarity and resistance to scratching and shattering.
3Strength
If polycarbonate material or steel cage goggles are used, then protection is provided, but glare is produced in the sun and fogging occurs in cold, wet or humid weather
Solution Approach 1:
The patent incorporates anti-glare coatings and fog-resistant treatments on the polycarbonate shield that modify optical properties. These surface treatments reduce glare from sunlight and prevent condensation fogging in cold or humid conditions while maintaining transparency.

AI summary
Protective eyewear includes a frame having a first side with a first member and an opposing second side with a second member. A foldable strap has openings at either end and is folded about the first and/or the second member and is held in place by a clip. The clip has a base portion and a swivel portion. The base portion and the swivel portion of the clip engage one another at least partially within the openings of the folded strap. The swivel portion has a range of rotation relative to the base portion of the clip.
