Solution Overview

Problem

Existing crimping systems for jewelry and timepieces fail to effectively create a visual vibration effect of gemstones due to limited movement and aesthetics issues, such as visibility of spring components and fragility, especially with small stones.

Innovation Solution

A crimping system comprising a crimping support with a gemstone, an elastic member, and a pin extending parallel to the axis of symmetry, where the elastic element is a deformable membrane capable of vibrating to oscillate the support around the axis, allowing for adjustable frequency and amplitude of movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a spiral or conical spring is used to connect the bezel to the support, then the stone can move and create vibration effect, but the spring becomes visible and undermines the aesthetics of the jewelry article

Engineering Contradiction:
Improvemovement of stoneVSAvoidaesthetics
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The spring is extracted from the visible interior and replaced by an invisible flexible membrane that performs the same connecting function without being visually detectable, thus resolving the contradiction between movement capability and aesthetic appearance

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The flexible membrane acts as an intermediary element between the bezel and support, providing the necessary flexibility and movement while remaining visually invisible, thus mediating between the functional requirement for movement and the aesthetic requirement for invisibility

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a pin is mounted through the upper part of the kitten to prevent separation, then the kitten remains fixed to the support, but the oscillations of the bezel are dampened and limited

Engineering Contradiction:
Improveprevention of separationVSAvoidoscillation of bezel
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The pin is removed from the system, eliminating the constraint that dampened oscillations, while the flexible membrane alone provides the necessary connection and movement capability, thus resolving the contradiction between prevention of separation and preservation of oscillation

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mechanical connection parameter is changed from rigid pin fixation to flexible membrane connection, allowing the system to maintain reliability through the membrane's inherent flexibility rather than through restrictive pin positioning, thus enabling full oscillation without permanent fixation

Inventive Principle:
Principle #35Parameter changes

3Length of moving object

If small springs are used for small stones, then the stone can be properly sized, but the springs deform excessively when the stone moves

Engineering Contradiction:
Improvesize of springVSAvoiddeformation of spring
Core Design Contradiction:
Length of moving objectVSReliability

Solution Approach 1:

The material parameter of the spring is changed from traditional metal to flexible membrane material, which has superior elasticity and resistance to permanent deformation, allowing small springs to move without excessive deformation while maintaining their size-appropriate functionality

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The flexible membrane is composed of elastomeric or polymeric materials that combine flexibility with high elastic recovery, creating a composite material that can deform during stone movement and then return to its original shape, thus preventing permanent deformation in small springs

Inventive Principle:
Principle #40Composite materials

4Stability of the object's composition

If the elastic element is made rigid to maintain structure, then the assembly is stable, but the visual vibration effect is reduced

Engineering Contradiction:
Improvestructural stabilityVSAvoidvisual vibration effect
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The rigidity parameter of the elastic element is optimized to a specific range that allows both structural stability and sufficient flexibility for vibration, using flexible membrane materials that provide the right balance between maintaining the bezel's structural integrity and enabling the visual vibration effect

Inventive Principle:
Principle #35Parameter changes
