Magnetic Lens Coupling for Sports Goggle Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current snow and sand goggles have limited peripheral vision and cumbersome lens replacement mechanisms, requiring users to remove their gloves or leave the field to change lenses, which hampers efficiency and safety during activities.
Innovation Solution
The design incorporates a frame with male and female coupling interfaces or magnetic coupling systems on the lens and frame, allowing for easy attachment and detachment of lenses without substantial tactile resources, enhancing peripheral vision and enabling quick lens changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a traditional frame design is used to secure the lens, then the lens is firmly attached to the frame, but the peripheral viewing ability is decreased
Solution Approach 1:
The goggle system is divided into separate modular components: a frame and a lens assembly that can be independently attached and detached. The lens assembly includes its own bracket structure with coupling interfaces, separating the lens securing function from the main frame structure. This segmentation allows the frame to maintain a simpler design that does not obstruct peripheral vision while the lens assembly provides secure attachment through its integrated bracket and coupling mechanisms.
2Adaptability or versatility
If a replaceable lens mechanism is added to allow lens changes, then lens adaptability is improved, but the mechanism becomes burdensome and difficult to manipulate with gloved hands
Solution Approach 1:
The coupling interface between the lens bracket and frame replaces complex mechanical fastening systems with magnetic coupling. The magnetic coupling interfaces consist of magnetic portions on both the lens bracket and frame that attract and secure the lens assembly to the frame. This magnetic mechanism eliminates the need for screws, clips, or other tactile manipulations, allowing users to easily attach and detach lenses even while wearing gloves. The magnetic force provides secure attachment during use while allowing simple separation when lens changes are needed.
3Device complexity
If the lens is permanently attached to the frame, then the structure is simplified, but lens interchangeability is lost
Solution Approach 1:
The lens attachment system transitions from a static permanent attachment to a dynamic removable and reattachable connection. The magnetic coupling interfaces enable the lens assembly to be easily attached to and detached from the frame multiple times throughout the product lifecycle. This dynamic capability allows users to interchange lenses based on different lighting conditions, activities, or lens damage, providing adaptability while maintaining relatively simple structural design through the modular frame and lens assembly components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution provides an increased field of vision and easier lens interchange, allowing users to quickly adapt to changing conditions or replace damaged lenses, thereby improving safety and convenience during sports and outdoor activities.
Implementation Method 1
The lens technology utilizes magnetic coupling interfaces located on peripheral edges of the lens to adhere the lens to the frame via interaction of the magnetic coupling interfaces with corresponding magnetic coupling interfaces located on the frame.
Implementation Method 2
The lens technology disclosed herein is an application of lens to frame techniques which utilize a male system of coupling interfaces located on peripheral edges of the lens to adhere the lens to the frame via interaction of the male interfaces with female receivers located on the frame.

AI summary
An interchangeable lens assembly including a first lens, a lens bracket coupled to the first lens, and at least one connection portion disposed around at least a portion of a perimeter of the lens bracket. A goggle including a goggle frame and at least one coupling point disposed on the goggle frame and adapted to couple to the at least one connection portion on the lens bracket. The at least one coupling point and the at least one connection portion may be corresponding magnetic portions adapted to couple to each other by a magnetic interaction, and/or the at least one connection portion may be a protrusion, and the at least one coupling point may be an aperture adapted to receive and couple to the protrusion. This allows the lens assembly to be attached to and detached from the goggle frame quickly and easily with reduced manual dexterity.
