Removable Eyeglass Lenses via Embedded Magnets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyeglasses do not allow for easy and convenient removal of lenses for tasks such as applying makeup or inserting contact lenses, as users must fully remove their glasses, which is inconvenient and not multifunctional.
Innovation Solution
A pair of eyeglasses with a frame design featuring hinged earpieces and rims, where magnets embedded in the frame and lenses enable individual and removable lens attachment, allowing for easy detachment and reattachment for optical-related tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional eyeglasses with fixed lenses are used, then the structural stability and simplicity are maintained, but the ease of operation for lens removal is poor requiring full glasses removal
Solution Approach 1:
The patent divides the eyeglass system into separable components: the frame and the lenses are independently detachable through magnetic attachment. This segmentation allows the lens to be removed individually without removing the entire glasses assembly, solving the contradiction by enabling partial disassembly for ease of operation while maintaining overall structural simplicity through modular design.
Solution Approach 2:
The patent replaces traditional mechanical lens retention mechanisms (screws, clips, or permanent bonding) with a magnetic field-based attachment system. This substitution eliminates complex mechanical fastening structures while providing sufficient holding force, thereby improving ease of lens removal and reattachment without significantly increasing structural complexity.
2Ease of operation
If magnets are embedded in the frame and lenses for removable attachment, then the ease of operation for lens detachment is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent extracts the lens from the permanent structure by enabling its independent removal through magnetic attachment. The lens can be taken out individually when needed (for eye drops, makeup, etc.) and reattached when not needed, providing the functionality of removable components without requiring complex assembly mechanisms during manufacturing.
Solution Approach 2:
The patent changes the attachment parameter from permanent mechanical bonding to reversible magnetic attraction. This parameter change allows the lens to be easily detached and reattached by simply overcoming the magnetic force, which can be done by pulling the lens away from the frame. The magnetic strength can be optimized during manufacturing to provide sufficient holding force while allowing easy removal, balancing ease of operation with manufacturing feasibility.
3Adaptability or versatility
If magnets are used for lens attachment, then the versatility for multiple tasks is improved, but the reliability of lens retention may be compromised
Solution Approach 1:
The patent implements universality by enabling the eyeglasses to perform multiple functions: the lenses can be retained for vision correction, easily removed for eye care tasks (applying drops, removing debris), and quickly reattached. The magnetic attachment system provides a universal solution that accommodates various user needs without requiring different mechanisms for different tasks, thereby improving versatility while maintaining adequate reliability through optimized magnetic strength.

AI summary
An eyeglass frame each has a plurality of first magnets located at each eye section and a pair of lens, each having a plurality of second magnets, able to be removably connected to the first magnets. This provides a way to removably attach an individual lens to a corresponding eye section of the frame.
