Timepiece Dial Composite with Electroplated Through-Hole Decoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing timepiece dials, such as those using mother-of-pearl sheets, lack diversity in design and aesthetic appeal, leading to a monotonous appearance.
Innovation Solution
A timepiece component is manufactured by bonding a conductive base and a nonconductive base, with through-holes in the nonconductive base electrolytically plated to form decorative layers, enhancing the dial's design and aesthetic appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a mother-of-pearl sheet is used for the dial, then the dial has coloration and aesthetic appeal, but the design becomes monotonous and lacks variety
Solution Approach 1:
The dial is segmented into multiple functional layers: a base layer, a mother-of-pearl sheet layer, and a decorative layer with metallic particles. This segmentation allows each layer to contribute different aesthetic properties, enabling design variety while maintaining manufacturing efficiency. The decorative layer can be independently designed with different metallic particle patterns, colors, and densities.
Solution Approach 2:
The invention uses a composite structure combining a mother-of-pearl sheet with a decorative layer containing metallic particles. This composite material approach allows the dial to exhibit both the iridescent coloration of mother-of-pearl and the metallic aesthetic of the decorative layer, creating enhanced design variety without sacrificing manufacturing ease.
2Adaptability or versatility
If a decorative layer is electrolytically plated in through-holes, then design variety and aesthetic appearance are enhanced, but manufacturing complexity increases
Solution Approach 1:
Through-holes are formed in the mother-of-pearl sheet before the decorative layer is applied. This preliminary action allows the decorative layer to be electrolytically plated directly into the pre-formed holes, simplifying the overall manufacturing process. The through-holes serve as ready-made receptacles for the metallic particles, eliminating the need for complex post-processing steps.
Solution Approach 2:
The invention replaces complex mechanical assembly processes with electrolytic plating. Instead of manually or mechanically placing metallic particles into holes, the decorative layer is applied through electrolytic plating, which automatically deposits metallic particles into the through-holes. This substitution significantly reduces manufacturing complexity while maintaining design flexibility.
3Ease of manufacture
If the nonconductive base is perforated with through-holes, then decorative layers can be plated, but the structural integrity may be compromised
Solution Approach 1:
The through-holes are strategically positioned and sized to maintain local structural quality. The holes are distributed in patterns that do not concentrate stress, and their dimensions are optimized to provide sufficient structural support while allowing decorative plating. This local quality approach ensures that the mother-of-pearl sheet maintains its strength despite the presence of through-holes.

AI summary
A dial that is a timepiece component includes a conductive base and a nonconductive base bonded to the conductive base. The nonconductive base has a through-hole extending from a back surface to a front surface of the nonconductive base, with the back surface being bonded to the conductive base. The through-hole is electrolytically plated with a decorative layer. The decorative layer serving as metallic decoration is added to the nonconductive base exposed at a front surface of the dial that is a timepiece component. Thus, the timepiece component can vary widely in design and has enhanced aesthetic appearance.
