Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional pierced earring attachments for eyeglasses can damage the lens or rim, are difficult to attach and detach, cause discomfort due to vibrations, and may injure the skin with protrusions.

Innovation Solution

An accessory with an insertion part made of a metal core combined with an elastic sheathing member, which is inserted into a through hole in the lens and fixed with a repulsive force, ensuring the core does not contact the lens during use and is securely attached, preventing loss and injury.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a metal core pierced earring is inserted into the attachment hole of the lens, then the accessory can be attached to eyeglasses to enhance beauty and fashionability, but the core may damage the lens or rim when erroneously touching during insertion

Engineering Contradiction:

Improveaccessory attachment capabilityVSAvoidlens damage risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

An elastic sheathing member is introduced as an intermediary between the metal core and the lens. This sheathing member contacts the lens surface instead of the metal core, preventing direct metal-to-lens contact that would cause damage. The elastic material provides a soft, non-damaging interface while still allowing secure attachment through the through-hole in the lens.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If a small hole is provided in the lens for pierced earring attachment, then the accessory can be attached to eyeglasses, but exacting work is required for insertion and the parts tend to be lost when detached

Engineering Contradiction:

Improveaccessory attachment capabilityVSAvoidattachment and detachment ease

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The insertion core part and the basic accessory part are merged into a single integrated component. This eliminates the need for separate parts (core and catch) that could be lost, and simplifies the attachment process to a single insertion motion through the through-hole, reducing the exacting work required while maintaining secure attachment.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If the core of the pierced earring is inserted into the hole in the lens, then the accessory can be attached, but a discomfort sound is produced due to movement of the core during vibrations in eyeglasses use

Engineering Contradiction:

Improveaccessory attachment capabilityVSAvoidvibration-induced discomfort sound

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The elastic sheathing member acts as a flexible element that surrounds and dampens the metal core. This flexible covering absorbs vibrations and prevents the metal core from moving freely, thereby eliminating the discomfort sound generated by metal-on-metal contact during eyeglasses use, while still allowing the accessory to be securely attached.

Inventive Principle:

Principle #30Flexible shells and thin films

4Adaptability or versatility

If the core of the pierced earring is made longer than the lens thickness, then the accessory can be attached, but the protruding portion may touch and injure face or hand skin when eyeglasses are worn

Engineering Contradiction:

Improveaccessory attachment capabilityVSAvoidskin injury risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The elastic sheathing member extends beyond the lens thickness to cover the protruding core portion. This flexible covering acts as a protective layer that prevents the sharp or hard metal core from contacting and injuring the skin, while still allowing the accessory to be attached and remain visible for decorative purposes.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

An accessory comprises an insertion part, which is inserted into a through hole provided in the direction of thickness of a lens of eyeglasses and configured by combining an insertion core part with a sheathing member made of an elastic material, and a basic accessory part arranged jointly at an end of the insertion core part on the side of a surface of the lens. The insertion part is fixed to the lens by being pressed against the through hole with repulsive force caused by the compression of the sheathing member.
