Solution Overview

Problem

Existing gemstone settings in watches, rings, and pendants suffer from noise issues due to tilting movements and wear, while also failing to maximize the luster effect of the gemstone.

Innovation Solution

A setting with a bearing element that acts as a pivot point to limit tilting movement, incorporating a socket base with a holding element and an annular stop to prevent wear and noise, and optionally featuring a flexible cushion and hemispherical reflection surface to enhance light reflection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the gemstone is allowed to move within the setting to enhance sparkle, then the luster effect is improved, but noise is generated and wear occurs

Engineering Contradiction:
Improveluster effectVSAvoidnoise
Core Design Contradiction:
Illumination intensityVSObject-generated harmful factors

Solution Approach 1:

A bearing element is introduced as an intermediary component between the gemstone setting and the frame. This bearing element absorbs the tilting movements of the gemstone, allowing the setting to move freely for enhanced sparkle while preventing direct contact between the setting and frame that would generate noise and wear.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Illumination intensity

If the gemstone is allowed to tilt to create optical effects, then the luster effect is improved, but wear of the frame occurs

Engineering Contradiction:
Improveluster effectVSAvoidwear resistance
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The bearing element serves as a mediator that decouples the moving setting from the stationary frame. It allows the setting to tilt and rotate for optimal light reflection while preventing direct mechanical contact that would cause wear and reduce reliability over time.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If a simple stop is used to limit gemstone movement, then the structure is simple, but noise is generated during movement

Engineering Contradiction:
Improvestructure simplicityVSAvoidnoise
Core Design Contradiction:
Device complexityVSObject-generated harmful factors

Solution Approach 1:

Instead of using a simple stop that directly contacts the setting and generates noise, a bearing element is introduced as an intermediary. This bearing element provides the stopping function through friction or controlled contact while isolating the noise-generating interaction from the main setting structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution achieves a noise-free, long-lasting gemstone setting that enhances the luster effect by allowing controlled tilting movements without wear, maintaining optical impact and reducing noise.

Implementation Method 1

a bearing element is provided, which supports the movement as a pivot point and thereby forms a stop for the size of the pivoting movement

Methodology Applied
Scientific EffectPivot point rotation: Gimbal

Implementation Method 2

a holder cushioned by a flexible element is provided below the gemstone in the socket

Methodology Applied
Scientific EffectElastic cushioning: Elasticity

Implementation Method 3

a hemispherical reflection surface above the mount, which further intensifies the effect of light incident on the gemstone through the mount

Methodology Applied
Scientific EffectLight reflection: Reflection
