Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Decorating horological components made of hard materials like ceramic is challenging due to limitations in surface decoration techniques, and existing methods fail to provide multi-colored or multi-appearance designs with sufficient wear resistance.
Innovation Solution
A method involving the production of horological components with multiple layers of inserts made from different materials, where cavities are machined and filled with polymers or metals to create complex, multi-colored designs with varying appearances, allowing for nested structures and high mechanical strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surface deposition techniques (pad printing, silkscreen, digital printing) are used to decorate ceramic components, then decoration can be applied to the surface, but the wear resistance is insufficient and multi-colored or multi-appearance designs are not achieved
Solution Approach 1:
The component is divided into multiple cavities at different depths within the ceramic structure. Each cavity is filled with a different material (colored polymer, lacquer, or metal-polymer combination) to create distinct decorative areas. This segmentation allows multiple decorations with different appearances and colors while maintaining the wear resistance of the ceramic substrate.
Solution Approach 2:
The patent implements a nested cavity structure where secondary cavities are created within primary cavities, and tertiary cavities within secondary cavities. Each nested cavity can be filled with different materials to create multi-layered, multi-colored decorations. This nesting approach enables complex multi-appearance designs while preserving the structural integrity and wear resistance of the outer ceramic layers.
2Manufacturing precision
If a cavity is filled with a single type of lacquer or colored polymer, then clean filling with acceptable resolution is achieved, but only a single color or single type of decoration is obtained
Solution Approach 1:
The single cavity filling approach is segmented into multiple cavity filling operations. Primary cavities are filled first with one material, then secondary cavities within them are filled with different materials, and finally tertiary cavities are filled with yet another material. This sequential segmentation enables multi-colored and multi-appearance decorations while maintaining clean filling quality for each material type.
Solution Approach 2:
The patent adds the depth dimension to decoration creation by forming cavities at different depths within the ceramic component. This vertical dimensionality allows multiple decorative layers to be stacked, with each layer filled with different materials. The depth variation enables complex multi-appearance designs while preserving the precision and cleanliness of each individual filling operation.
3Adaptability or versatility
If multiple surface decoration techniques are applied to achieve multi-colored designs, then decoration variety is increased, but the wear resistance guarantees required in the horological industry are not met
Solution Approach 1:
Different local regions of the ceramic component are given different qualities through selective cavity filling. Each cavity or nested cavity sequence can contain materials with different optical, mechanical, or aesthetic properties. This local quality variation enables diverse decorations in different areas while the overall ceramic structure maintains uniform wear resistance throughout.
Solution Approach 2:
The patent uses composite material structures where ceramic provides the wear-resistant substrate, and embedded cavities contain filled materials such as colored polymers, lacquers, or metal-polymer combinations. This composite approach combines the wear resistance of ceramic with the aesthetic versatility of multiple fill materials, achieving both durability and decoration variety simultaneously.
