Solution Overview

Problem

Jewelry items typically come with permanent designs that cannot be easily modified or tailored for specific occasions or outfits, leading to a costly and impractical accumulation of various pieces, and existing modular systems often require complex assembly with screwing and spring clasps.

Innovation Solution

A jewelry linking system featuring a pin with two arms that can be pressed together and a sleeve that slides along a chain, allowing for easy attachment and detachment of jewelry elements without losing any components, providing a secure and aesthetically integrated clasp mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If modular jewelry systems use screwing and spring clasps, then jewelry elements can be interchangeable, but assembly becomes complex and time-consuming

Engineering Contradiction:
Improveinterchangeability of jewelry elementsVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The clasp is divided into two separate components: a pin component with arms and a sleeve component. This segmentation allows each part to be simple in design while achieving complex functionality when assembled, eliminating the need for screws or springs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pin component is inserted into the sleeve component, with the pin's arms fitting inside the sleeve's interior surface. This nesting arrangement creates a secure connection through simple insertion and elastic retention, avoiding complex assembly mechanisms.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If jewelry items have permanent designs, then structural integrity is maintained, but they cannot be modified or tailored for specific occasions

Engineering Contradiction:
Improvedesign flexibilityVSAvoidstructural integrity
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The jewelry system transitions from a static permanent design to a dynamic interchangeable design. The clasp mechanism allows the jewelry composition to change over time, enabling users to swap pendants, charms, and other elements while maintaining structural integrity through the secure pin-and-sleeve connection.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If clasp elements are easily detachable for interchangeability, then jewelry can be modified, but elements may get lost during changes

Engineering Contradiction:
Improveease of element replacementVSAvoidelement retention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The sleeve's elastic interior surface automatically retains the pin component through elastic retention. When the pin is inserted, the elastic material naturally grips it, and when the pin is pulled, the elastic material maintains continuous contact to prevent accidental detachment. This self-retaining mechanism eliminates the need for additional locking features.

Inventive Principle:
Principle #25Self-service

4Adaptability or versatility

If multiple jewelry pieces are owned to cover different occasions, then design variety is achieved, but cost and impracticality increase

Engineering Contradiction:
Improvedesign varietyVSAvoidnumber of jewelry pieces
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The clasp mechanism serves multiple functions: it provides secure attachment, enables easy interchangeability, prevents element loss, and works with various jewelry types (necklaces, bracelets, anklets). This universal design allows a single clasp system to support diverse jewelry configurations, reducing the need for multiple specialized pieces.

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

AI summary

A clasp for a jewelry system has two arms and a sleeve that can slide to a position covering at least portions of both arms. In this position, the sleeve urges the clasp from an un-locked state towards a locked state.
