Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing coloring techniques for metal golf shafts result in a colored layer with low adhesion, which tends to peel off during bending processes.
Innovation Solution
A multi-layered colored plating layer structure comprising a semigloss plating layer, a first strike plating layer, a satin-like plating layer, a second strike plating layer, and a decorative plating layer, where each layer enhances adhesion and durability, specifically using nickel and trivalent chromium plating to ensure peeling resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a colored layer is formed on a metal shaft using conventional painting techniques, then the designability of the shaft is enhanced, but the adhesion of the colored layer becomes low and it peels off during bending processes
Solution Approach 1:
The colored plating layer is divided into multiple functional sub-layers: a base plating layer for adhesion, an intermediate plating layer for transition, and a decorative plating layer for color and finish. This segmentation allows each layer to specialize in specific functions, with the base layer ensuring strong bonding to the metal shaft and the decorative layer providing aesthetic properties without compromising adhesion.
Solution Approach 2:
The invention uses a composite plating structure combining different metallic materials with distinct properties. The base plating layer uses materials with high adhesion to the metal shaft, while the decorative plating layer uses materials providing desired color and surface finish. This composite approach integrates the benefits of different materials to simultaneously achieve strong adhesion and aesthetic appearance.
2Shape
If a colored layer is applied to a metal shaft, then the appearance is improved, but the colored layer lacks peeling resistance during bending processes
Solution Approach 1:
The base plating layer is applied in advance to the metal shaft surface before the decorative colored layer. This preliminary layer is specifically designed to bond strongly to the metal substrate, creating a stable foundation that prevents peeling during subsequent bending operations. The preliminary action of applying this adhesion-promoting layer ensures the colored appearance will remain intact under mechanical stress.
Solution Approach 2:
Different regions of the plating structure have different properties optimized for their specific functions. The base plating layer has high adhesion properties localized at the interface with the metal shaft, while the decorative plating layer has aesthetic properties localized at the outer surface. This local differentiation of material properties allows the system to simultaneously achieve strong peeling resistance at the substrate interface and desirable appearance at the surface.
