Solution Overview

Problem

Existing eyeglasses designs make it difficult and costly for users to replace temples, leading to inconvenience and aesthetic issues due to exposed pivotal members that can rust and affect the smooth rotation of temples, as well as difficulties in removing eyeglasses with a neck cord.

Innovation Solution

A pair of eyeglasses with a glasses frame, connecting members, and temples that utilize magnetic coupling bases and pivot systems for secure and convenient attachment and detachment, allowing temples to be easily replaced and the eyeglasses to be worn with a neck cord without hindrance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If temples are directly joined to the glasses frame with a pivotal member such as a screw or a pin, then the temples can be folded or unfolded, but the pivotal member is externally exposed and easily smudged or rusted, affecting the appearance and smooth rotation of the temples

Engineering Contradiction:
Improvetemple rotation smoothnessVSAvoidpivotal member smudging and rusting
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The pivotal member is extracted from the external exposure and relocated to an internal position within the coupling base. The coupling base includes a cavity that accommodates the pivotal member, shielding it from external exposure while maintaining the temple's rotational functionality. This extraction eliminates the harmful effects of smudging and rusting on the external appearance.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The pivotal member is nested within the coupling base structure. The coupling base contains a cavity that houses the pivotal member, creating a nested arrangement where the pivotal member is protected within the larger coupling base structure. This nesting protects the pivotal member from external environmental factors while preserving its rotational function.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If temples are directly joined to the glasses frame with a pivotal member, then the temples can be folded or unfolded, but it requires tools to remove the pivotal member and strenuous effort to secure it at a new temple, making temple replacement difficult

Engineering Contradiction:
Improvetemple replaceabilityVSAvoidtemple replacement convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The connecting member is segmented into multiple parts: a first segment that couples to the glasses frame and a second segment that connects to the temple. This segmentation allows the temple to be independently replaced without affecting the glasses frame, while the magnetic coupling mechanism enables easy attachment and detachment without tools or strenuous effort.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The traditional mechanical fastening system (screws or pins requiring tools) is replaced with a magnetic coupling system. The magnetic coupling mechanism allows for tool-free attachment and detachment of the temple, significantly improving the ease of temple replacement while maintaining secure connection.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If a neck cord is added to the eyeglasses, then the eyeglasses can be conveniently removed and reattached, but the existing pivotal member structure may interfere with the neck cord attachment and removal process

Engineering Contradiction:
Improveeyeglasses removal and reattachmentVSAvoidcoupling structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The coupling base is designed with multi-functionality: it provides both the magnetic coupling function for temple attachment and the neck cord attachment function. The coupling base includes a cavity for the pivotal member and an external attachment point for the neck cord, allowing it to serve multiple purposes without increasing overall structural complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A pair of eyeglasses with replaceable temples includes a glasses frame, two connecting members, and two temples. The glasses frame includes a first end and a second end spaced from the first end in a lateral direction, each of which forms a coupling base extending inward in a longitudinal direction perpendicular to the lateral direction. A recess and a first magnet are included in each coupling base. A first segment of each connecting member is held in the recess of a corresponding coupling base. A second magnet is included in the first segment of each connecting member and coupled with the first magnet in the corresponding coupling base to allow the connecting members to be securely coupled with the glasses frame. A front end of each temple is engaged with a second segment of one of the connecting members. The pair of eyeglasses features temples removed and fixed conveniently.
