Interchangeable Eyeglass Frames Using Magnetic Attachment

Solution Overview

Problem

Existing eyeglasses designs do not provide a simple and efficient way to change the entire look of the frame and temples, with previous attempts focusing on small, interchangeable ornamental pieces that do not alter the overall appearance.

Innovation Solution

The design incorporates interchangeable frame portions with selectively engageable connections, such as magnets and screws, allowing users to easily swap out entire frame and temple sets, including ornamental linking portions that can be attached to the lenses or lens frames.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If small, interchangeable ornamental pieces are used to modify eyeglasses, then the ability to change appearance is improved, but the overall look of the eyeglasses cannot be fully transformed

Engineering Contradiction:

Improveability to change appearanceVSAvoidextent of transformation

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The eyeglasses are divided into distinct modular components: a permanent base structure (frame, bridge, temples, earpieces) and interchangeable front assemblies (each consisting of a front frame and lenses). This segmentation allows users to swap entire front assemblies to completely change the appearance, rather than being limited to small ornamental pieces. The modular design enables full transformation of the eyeglass look while maintaining a stable base structure.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If removable portions are added to eyeglasses, then aesthetic customization is improved, but the assembly becomes inefficient and complex

Engineering Contradiction:

Improveaesthetic customizationVSAvoidassembly efficiency

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The eyeglasses are divided into distinct modular components: a permanent base structure (frame, bridge, temples, earpieces) and interchangeable front assemblies (each consisting of a front frame and lenses). This segmentation allows users to swap entire front assemblies to completely change the appearance, rather than being limited to small ornamental pieces. The modular design enables full transformation of the eyeglass look while maintaining a stable base structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The interchangeable front assembly utilizes a magnetic attachment system rather than traditional mechanical fasteners. Magnets embedded in the permanent frame and front frame create a secure yet easily removable connection. This magnetic system replaces complex mechanical assembly mechanisms, allowing users to simply snap the front assembly onto the frame for quick aesthetic customization without dealing with screws, clips, or other mechanical fastening systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Strength

If traditional mechanical fasteners are used to attach frame portions, then connection strength is improved, but ease of interchange is reduced

Engineering Contradiction:

Improveconnection strengthVSAvoidease of interchange

Core Design Contradiction:

StrengthVSEase of operation

AI summary

An interchangeable frame for eyeglasses is disclosed including a first lens, a second lens, an interchangeable frame portion, and at least one selectively engageable connection between the interchangeable frame portion and at least one of the first and second lenses. The interchangeable frame portion may include a first temple, second temple, and linking portion between the first and second temples. The first and second lens may be surrounded and/or connected by a lens frame portion. The selectively engageable connection may include at least one of a magnet and a screw. The interchangeable frame portion is interchangeable with the first and second lens. Accordingly, a user may selectively interchange the interchangeable frame portion, such as to change the decorative or ornamental appearance of the eyeglasses.
