Magnetic Goggle Frame Coupling for One-Handed Helmet Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective goggles for helmets, particularly motocross goggles, face challenges with strap-based fastening systems that require both hands for fitting and removal, are prone to dirt and damage, and lack precise centering, making them difficult to use, especially in muddy conditions, and are not easily interchangeable.
Innovation Solution
A goggle frame with magnetic coupling means on the inner side and gripping means on the outer side, paired with a corresponding device inside the helmet, allows one-handed attachment and detachment without touching sensitive areas, and can be hung on handlebars or clothing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a strap is used to fasten the goggles to the helmet, then the goggles can be securely attached to the helmet, but both hands are required for fitting and removal, and the strap is prone to dirt and damage in muddy conditions
Solution Approach 1:
The patent replaces the elastic strap mechanism with a magnetic coupling system. Magnetic attractors are embedded in the goggle frame at the temples, which interact with magnetic attractors in the helmet's facial aperture. This magnetic field-based system eliminates the need for a strap, allowing secure attachment through magnetic attraction while enabling easy one-handed attachment and removal by simply bringing the goggles close to the helmet for magnetic engagement.
2Ease of operation
If the strap is used for fastening, then the goggles can be removed by pulling the strap, but the strap can get caught between the face and goggles, requiring both hands to prevent this
Solution Approach 1:
The magnetic coupling system replaces the strap-based removal mechanism. The magnetic attractors in the goggle frame and helmet create a magnetic field that holds the goggles securely. To remove, the user simply pulls the goggles away from the helmet, and the magnetic attraction naturally releases as the distance increases, eliminating the need for complex strap manipulation or two-handed operations.
3Ease of operation
If the goggle frame is pulled by the edges to remove goggles, then the goggles can be detached, but the foam filter covering the ventilation holes can be damaged
Solution Approach 1:
The magnetic coupling system eliminates the need to physically pull or grip the goggle frame edges for removal. The magnetic attraction provides secure attachment during use, and removal is achieved by simply moving the goggles away from the helmet, allowing the magnetic field to naturally release without applying mechanical stress to the foam filter or frame edges.
4Ease of operation
If the goggles are worn directly on the head without a helmet, then they can be removed by pulling the frame, but the foam filter can be damaged due to the pulling force
Solution Approach 1:
The magnetic coupling system provides secure attachment when worn with a helmet, and when worn directly on the head, the magnetic attractors can be engaged with ferromagnetic surfaces or simply held in place by the magnetic field interaction. Removal is achieved by moving the goggles away, allowing natural magnetic release without damaging the foam filter or requiring forceful pulling.
5Adaptability or versatility
If the strap is used for fastening, then the goggles can be hung from handlebars, but the strap can slip off in muddy conditions
Solution Approach 1:
The magnetic coupling system eliminates the strap entirely. The goggle frame itself, with its magnetic attractors, can be directly engaged with ferromagnetic surfaces such as motorcycle handlebars or helmet surfaces. This provides secure hanging capability through magnetic attraction that is not affected by mud or dirt, eliminating the slipping problem associated with textile straps.
