Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for carrying eyeglasses, such as neck cords, are inconvenient, unsightly, and prone to causing damage or loss, as they allow the glasses to dangle and swing, and may snag clothing or become detached.

Innovation Solution

A body-worn eyeglass holder with a first member for engaging a buttonhole and a second member for receiving a temple piece, connected by a connector that allows the first member to pass through the buttonhole from the back while keeping the second member on the front side, securing the holder to the clothing and preventing removal without a button.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If eyeglasses are placed in a shirt pocket, then they are easily accessible, but they fall out when one bends over

Engineering Contradiction:

ImproveAccessibility of eyeglassesVSAvoidRetention of eyeglasses

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The holder is divided into two separate members: a first member that engages the buttonhole and a second member that receives the temple piece. This segmentation allows the holder to be securely anchored while providing a dedicated receptacle for the eyeglasses, solving both accessibility and retention issues.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The second member (receiving the temple piece) is positioned within the structure defined by the first member (engaging the buttonhole), creating a nested arrangement where the eyeglasses are held securely within the holder assembly that is itself secured to the garment.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If eyeglasses are placed in a pants pocket, then they are protected from falling out, but they may be bent or broken

Engineering Contradiction:

ImproveRetention of eyeglassesVSAvoidDamage to eyeglasses

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The second member is specifically designed with a closed-loop circular ring structure that provides localized protection for the temple piece. This specialized structure cradles the eyeglasses in a controlled environment rather than allowing them to tumble freely in a pocket, preventing bending and breaking while maintaining secure retention.

Inventive Principle:

Principle #3Local quality

3Reliability

If a cord is attached to retain eyeglasses around the neck, then loss is prevented, but the glasses dangle and swing wildly

Engineering Contradiction:

ImprovePrevention of lossVSAvoidPosition stability of eyeglasses

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

By separating the anchoring function (first member in buttonhole) from the holding function (second member for temple piece), the design eliminates the dangling cord while maintaining secure retention. The eyeglasses are held in a fixed position relative to the garment rather than hanging freely.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connector acts as an intermediary element that links the buttonhole-engaging first member to the temple-piece-receiving second member. This intermediary structure provides a stable, fixed connection that prevents the eyeglasses from swinging while allowing them to be securely retained.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Ease of operation

If a cord is used to carry eyeglasses, then they are retained around the neck, but it leaves room for the glasses to dangle and get in the way

Engineering Contradiction:

ImproveConvenience of carryingVSAvoidPosition stability of eyeglasses

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The design extracts the cord from the system entirely, replacing it with a buttonhole-engaging holder that provides secure retention without the dangling problem. The eyeglasses are held in a fixed position on the garment rather than hanging from a cord around the neck.

Inventive Principle:

Principle #2Taking out (Extraction)

5Ease of operation

If clips or pins are attached to clothing to hold eyeglasses, then they are easily accessible, but they may snag the clothing or become detached

Engineering Contradiction:

ImproveAccessibility of eyeglassesVSAvoidAttachment security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The holder is segmented into a first member that engages the buttonhole structure and a second member that holds the temple piece. This segmentation allows secure attachment through the buttonhole mechanism without the need for clips or pins that can snag or detach, while maintaining easy accessibility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The nested arrangement of the two members within the buttonhole structure provides secure attachment that distributes forces evenly, preventing the holder from snagging clothing or becoming detached, while keeping the eyeglasses easily accessible.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

An eyeglass holder for securely retaining a temple piece of an eyeglass therein that prevents accidental loss of the eyeglass during non-use, and further prevents damage thereto is disclosed. The eyeglass holder engages a buttonhole of a shirt for secure retention of the eyeglass, and for secure engagement of the eyeglass holder to prevent loss of the eyeglass holder, such as during extraction of the temple piece.
