Solution Overview

Problem

There is a need for a method to easily and non-permanently attach decorative items to eyeglasses without damaging them, allowing consumers to personalize and upgrade their eyewear without incurring the cost of new glasses.

Innovation Solution

A device with a threaded shank portion compatible with eyeglass hinges, featuring a crown at the top for holding ornaments and a drive tool receiver at the bottom, allowing for secure attachment and removal without applying damaging torque, using a screwdriver inserted from the bottom and turned counter-clockwise.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional screw attachment method is used, then the decorative item can be attached to the eyeglasses, but torque and force applied during installation may damage the jewel or ornament

Engineering Contradiction:

Improveattachment processVSAvoiddamage to jewel

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent inverts the traditional screw installation approach by placing the drive tool receiver at the bottom end of the shank rather than the top. This allows the tool to be inserted from the bottom and rotated to advance the screw into the hinge, keeping the crown and jewel away from the application of torque and force during installation.

Inventive Principle:

Principle #13The other way round (Inversion)

2Adaptability or versatility

If decorative items are attached to eyeglasses, then aesthetic appeal is enhanced, but the attachment process may permanently damage the eyeglasses

Engineering Contradiction:

Improvepersonalization capabilityVSAvoidintegrity of eyeglasses

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the attachment device into distinct components: a crown for holding the jewel, a threaded shank portion for engagement with the hinge, and a drive tool receiver. This segmentation allows the decorative element to be attached through a standardized threaded interface that can be installed and removed without permanently damaging the eyeglasses.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent utilizes the threaded parameter of the hinge to enable reversible attachment. By designing the shank with threads compatible with the hinge's threaded hole, the attachment can be securely fastened during installation and equally securely removed afterward, preventing permanent damage while maintaining reliability throughout the attachment lifecycle.

Inventive Principle:

Principle #35Parameter changes

3Strength

If a crown is placed at the top of the screw to hold the jewel, then the jewel can be securely held, but applying torque from the top may damage the jewel

Engineering Contradiction:

Improveholding capabilityVSAvoidtorque damage to jewel

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A device for attaching a jewel or ornament to a hinge of a pair of eyeglasses having a threaded shank portion compatible with an eyeglass hinge threaded hole, a crown disposed at a top end of the threaded shank portion, and a drive tool receiver, such as a slot or crosspoint, disposed at the bottom end of the threaded shank portion. The device is installed into a threaded hole in a hinge by turning it with a tool which is inserted into the bottom of the hinge and rotating in an opposite direction of normal screw installation, thereby leaving the crown portion at the top of the screw available to hold a jewel or ornament while avoiding placing possible damaging torque and force on the jewel or ornament.
