Solution Overview

Problem

Conventional clip-on lenses for eyeglasses face issues such as difficulty in attachment, unintentional detachment, ghosting due to light seepage, risk of scratching, and aesthetic concerns, particularly with mechanical and magnetic mechanisms.

Innovation Solution

A magnetic eyeglasses attachment made from magnetically receptive materials like stainless steel, neodymium iron boron magnets, and flexible magnetic compounds that couples around the entire perimeter of the eyeglasses frame, preventing light seepage and reducing the risk of scratching, while allowing easy insertion and removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a mechanical clip mechanism is used to attach auxiliary lenses, then the attachment is secure, but it is difficult to attach and may require both hands

Engineering Contradiction:

Improveattachment securityVSAvoidattachment difficulty

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical clip mechanism with a magnetic attachment system. Magnets embedded in the auxiliary lenses magnetically attract to the eyeglass frame, eliminating the need for manual clipping while maintaining secure attachment. This allows single-handed operation and reduces dexterity requirements.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If a magnetic mechanism with small magnets is used, then the attachment is easier to detach, but it may detach unintentionally

Engineering Contradiction:

Improvedetachment easeVSAvoidattachment stability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent merges multiple magnets into an array distributed across the auxiliary lens surface, creating a combined magnetic field that increases total holding force. This distributed magnetic array prevents unintentional detachment while still allowing easy intentional removal when needed.

Inventive Principle:

Principle #5Merging (Combining)

3Device complexity

If limited attachment points are used in magnetic mechanism, then the structure is simpler, but bending or warping prevents magnet alignment and weakens attachment

Engineering Contradiction:

Improveattachment mechanism simplicityVSAvoidattachment strength under deformation

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent segments the magnetic attachment system into multiple distributed magnets rather than relying on a single attachment point. This segmentation allows the attachment to maintain effectiveness even when the frame bends or warps, as multiple magnets can still find alignment points across the deformed surface.

Inventive Principle:

Principle #1Segmentation

4Device complexity

If limited attachment points are used, then the mechanism is simpler, but gaps form between lenses allowing light to seep in causing ghosting

Engineering Contradiction:

Improveattachment mechanism simplicityVSAvoidlight seepage and ghosting

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent transitions from point-based magnetic attachment to a distributed magnetic array that covers the entire auxiliary lens surface. This dimensional expansion ensures complete perimeter contact with the frame, eliminating gaps that would allow light to seep in and cause ghosting effects.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

5Reliability

If a protruding clip mechanism is used, then the attachment is secure, but the clip may scratch the primary lens during attachment

Engineering Contradiction:

Improveattachment securityVSAvoidlens scratching risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the protruding mechanical clip with a magnetic field-based attachment system. The magnetic force acts through the lens materials without physical contact between the attachment mechanism and the primary lens surface, eliminating scratching risk while maintaining secure attachment.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

6Adaptability or versatility

If conventional clip-on design is used, then the functionality is achieved, but the appearance is not aesthetically pleasing to some consumers

Engineering Contradiction:

Improvefunctional versatilityVSAvoidaesthetic appearance

Core Design Contradiction:

Adaptability or versatilityVSShape

Solution Approach 1:

The patent employs thin magnetic layers and flexible magnetic compounds that allow the auxiliary lenses to conform closely to the frame surface. This creates a sleek, streamlined appearance without protruding elements, improving aesthetics while maintaining the functional versatility of removable attachments.

Inventive Principle:

Principle #30Flexible shells and thin films
