Magnetic Lens Attachment for Glasses Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glasses designs do not allow for easy and tool-free replacement of lenses, leading to increased financial burden and inconvenience for users, as current methods require directional force for disassembly and assembly, which can result in lens wear or instability.
Innovation Solution
A glasses structure featuring magnetic seats on the frame and lens units with magnetic elements that enable magnetic attraction and detachment, allowing for easy lens replacement without tools, with additional structural features like blocking walls and positioning slots to ensure stability and prevent displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If snap-fitting, fitting or fastening manners are used to enable lens replacement, then lens replaceability is improved, but directional force is required which may cause lens wear
Solution Approach 1:
The patent replaces mechanical fastening systems (snap-fitting, fitting, or fastening manners) with a magnetic field-based attachment system. Magnetic elements embedded in the frame and corresponding magnetic seats on the lens enable lens fixation through magnetic attraction, eliminating the need for directional mechanical force and preventing lens wear while maintaining easy replacement capability.
2Adaptability or versatility
If multiple glasses with different functions are owned for replacement, then functional versatility is improved, but financial burden on user increases
Solution Approach 1:
The patent implements a universal lens replacement system where users can easily swap between different lens types (optical lenses, sunglasses, sports glasses) in the same frame. The magnetic attachment mechanism allows for tool-free lens changes, enabling one pair of glasses to serve multiple functions by simply replacing the lens, thereby reducing the need to own multiple separate glasses and lowering financial burden.
3Ease of operation
If magnetic elements are added to enable magnetic fixation, then lens replaceability is improved, but device complexity increases
Solution Approach 1:
The patent merges the magnetic attachment function with the existing frame and lens structures. Magnetic elements are embedded within the frame's magnetic seats, and corresponding magnetic seats are integrated into the lens body. This merging approach allows the magnetic fixation function to be achieved without adding separate, complex attachment mechanisms, thereby maintaining structural simplicity while enabling easy lens replacement.

AI summary
Provided is a glasses structure, mainly including a frame, two temples, a lens unit and two blocking walls. Both sides of the frames are respectively provided with a first magnetic seat. Each of the temples is pivotally connected to both sides of the frame. The lens unit includes a lens body and a second magnetic seat arranged on both sides of the lens body. Each of the second magnetic seats can be magnetically attracted to each of the first magnetic seats. Each of the blocking walls and both sides of the frame jointly surround two sides of the lens unit. The lens unit is fixed on the frame by means of a magnetic manner, and the lens unit can be detached from the frame such that users can replace the lens unit by themselves.
