Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing decorative objects with embedded diamonds in ceramic materials lack precision and reproducibility in positioning the diamonds within the decorative object.
Innovation Solution
A method involving a vitrified substrate with at least 40% silica, forming a cavity, depositing a decorative element, and applying a heat treatment above the substrate's glass transition or melting temperature to deform and attach the element, ensuring precise positioning and attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heating is carried out above vitrification temperature to embed diamonds in ceramic, then the diamonds are attached in the ceramic, but precise positioning of the diamonds relative to the rest of the decorative object cannot be achieved
Solution Approach 1:
The cavity is formed in the substrate before the decorative element is deposited into it. This preliminary formation of the cavity at room temperature allows for precise positioning of the decorative element, as the element is placed into a pre-defined space rather than being embedded during high-temperature heating. The cavity acts as a positional template that ensures reproducibility and precision.
Solution Approach 2:
The patent utilizes changes in the physical state of the substrate material through temperature control. At room temperature, the substrate maintains a rigid structure with a precisely formed cavity. During heating above the glass transition temperature, the substrate becomes soft and deformable, allowing the cavity to close and embed the decorative element. This parameter change enables both precise positioning (at low temperature) and secure attachment (at high temperature).

AI summary
The invention relates to a method for manufacturing a decorative object, comprising the following steps: - obtaining a substrate (10), at least partially vitrified comprising at least 40% silica by weight, formed for example in enamel, having a glass transition temperature and/or a melting temperature, - forming in the substrate (10) a cavity comprising a part opening onto an external surface of the substrate (10), - depositing in the cavity a decorative element (20), such as a precious stone, - applying a heat treatment by heating the substrate (10) at least to a temperature higher than the glass transition temperature and/or the melting temperature, so as to allow a deformation of at least a portion of the opening part to attach the decorative element (20) in the cavity.
