Solution Overview

Problem

Conventional methods for crimping precious or semi-precious stones on non-ductile materials like glass, ceramics, or silicon substrates are ineffective, as these materials are difficult to machine and prone to irreversible damage.

Innovation Solution

A process for producing a bezel with deformable metal claws integrated into a non-ductile substrate, involving metallization, formation of a belt and claws using techniques such as deep etching, thermocompression, or photolithography, allowing for the secure seating and crimping of stones without adhesive bonding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional crimping methods are used on non-ductile substrates, then the substrate can be processed, but the substrate is damaged irreversibly

Engineering Contradiction:
Improvecrimping processabilityVSAvoidsubstrate damage
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

A metallic layer is deposited on the non-ductile substrate surface to serve as an intermediary medium. This metallic layer enables conventional crimping operations to be performed without directly contacting and damaging the fragile non-ductile substrate. The metallic layer absorbs the mechanical stress of crimping while providing a ductile surface for claw formation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The surface properties of the non-ductile substrate are changed by depositing a metallic layer, transforming the surface from fragile and non-ductile to ductile and crimpable. This parameter change allows the substrate to undergo crimping operations that would otherwise be impossible without damage.

Inventive Principle:
Principle #35Parameter changes

2Strength

If non-ductile materials like glass, ceramics, or silicon are used for substrates, then aesthetic and mechanical properties are improved, but machining and crimping become extremely difficult

Engineering Contradiction:
Improvemechanical properties and aesthetic renderingVSAvoidmachining and crimping difficulty
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The metallic layer acts as a mediator between the non-ductile substrate and the crimping process. It provides a ductile surface that can be easily machined and crimped, while the underlying non-ductile substrate maintains its superior mechanical and aesthetic properties.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The solution creates a composite structure combining the non-ductile substrate (glass, ceramic, or silicon) with a ductile metallic layer. This composite enables both the aesthetic and mechanical advantages of non-ductile materials and the manufacturability of ductile materials.

Inventive Principle:
Principle #40Composite materials

3Device complexity

If adhesive bonding is used instead of crimping, then crimping complexity is reduced, but the aesthetic and traditional quality of stone setting is compromised

Engineering Contradiction:
Improvecrimping process complexityVSAvoidaesthetic rendering and traditional craftsmanship
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The metallic layer enables traditional crimping techniques to be used on non-ductile substrates, preserving the aesthetic quality and craftsmanship of stone setting while avoiding the need for adhesive bonding. The metallic surface provides the necessary ductility for claw formation and stone securing.

Inventive Principle:
Principle #24Intermediary (Mediator)
