Solution Overview

Problem

Existing jewelry fixing techniques, such as gluing or deformation, often damage the structure or the ornamental element when attempting to replace it, and alternative systems that facilitate removal compromise aesthetics by making separation zones visible.

Innovation Solution

A jewelry article design featuring a ring nut with an internal thread and a closing cap formed by two coaxially fastened disks, which allows for easy disassembly and replacement of ornamental elements without altering the article's aesthetics, using a screwing mechanism that hides the thread and provides secure closure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If gluing or deformation techniques are used to fix ornamental elements, then the jewelry structure is strong and stable, but the ornamental element cannot be easily replaced and may be damaged during removal

Engineering Contradiction:
Improvefixing strengthVSAvoidelement replaceability
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The jewelry article is divided into separate components: a jewelry body, a removable cap, and an ornamental element. The cap can be detached from the body, allowing the ornamental element to be accessed and replaced without damaging the jewelry structure. This segmentation enables easy replacement while maintaining the strength of the overall structure when assembled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cap acts as an intermediary element between the jewelry body and the ornamental element. It provides a protective cover that can be removed to access the ornamental element for replacement, while maintaining the aesthetic appearance when closed. The cap serves as a mediator that allows easy access without compromising the structural integrity of the jewelry body.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of repair

If multiple parts are used to facilitate easy separation, then the ornamental element can be easily replaced, but separation zones become visible and aesthetics are compromised

Engineering Contradiction:
Improveelement replaceabilityVSAvoidaesthetic appearance
Core Design Contradiction:
Ease of repairVSShape

Solution Approach 1:

The functional elements necessary for replacement (screw threads, opening mechanisms) are extracted and hidden within the cap structure. The cap appears as a solid, aesthetic piece from the outside, but contains hidden mechanical features that enable easy removal. This extraction of functional elements from the visible surface maintains aesthetic appearance while enabling ease of replacement.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The screw threads and mechanical features are nested within the cap structure, similar to nested dolls. The cap has an outer aesthetic surface and inner functional components that are concealed within. When the cap is removed, the ornamental element can be accessed, but the complexity of the replacement mechanism is hidden within the cap's structure, maintaining the simplicity and aesthetics of the overall design.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Reliability

If deformation of gripping clips or coining of edges is used, then the ornamental element is securely fixed, but the structure may break or damage occurs during removal attempts

Engineering Contradiction:
Improvefixing securityVSAvoidstructural damage risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The fixing mechanism transitions from a static, permanent fixation (gluing, deformation) to a dynamic, reversible mechanical connection. The cap can be easily attached and detached through a simple screwing and unscrewing action, allowing secure fixation during wear while enabling damage-free removal for replacement. This dynamic mechanism eliminates the risk of structural damage associated with permanent fixation methods.

Inventive Principle:
Principle #15Dynamics

AI summary

A jewelry article (10, 110, 210) with an ornamental element (11) comprises a ring nut (12) with an internal seat (13) provided at one end of the ring nut with a first opening (14) for introduction of the ornamental element (11) and at an opposite end with a second opening (15) from which the ornamental element (11) emerges. A closing cap (16) closes the first opening (14) after the introduction of the ornamental element (11) into the seat (13). The closing cap (16) comprises a first peripherally threaded disk (18) and a second disk (19) with a face (24) which is intended to form an external closing surface of the first opening (14) of the ring nut. The two disks (18, 19) are fixed to each other. Fixing may be performed by means of fastening pins (26).
