Solution Overview
Problem
Conventional electroplating methods for garment accessories are labor-intensive and costly, particularly when attempting to achieve reversible or multi-colored designs, as they require full surface plating and complex masking processes, which are unsuitable for industrial production.
Innovation Solution
An electroplating apparatus utilizing a bipolar phenomenon to apply different metallic colors to the front and back surfaces of garment accessories by separating the accessories from electrodes in an electrolytic solution, generating a potential gradient for controlled metal deposition and dissolution, allowing for various hues and cost-effective mass production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional electroplating or chemical plating is used to impart metallic colors to garment accessories, then the metallic color can be changed from the base material color, but the process requires full surface plating and cannot achieve different colors on front and back surfaces without masking, which increases labor and cost
Solution Approach 1:
The patent divides the plating process into separate treatments for different surfaces of the garment accessory. By using masking to isolate the front surface during first plating, then masking the back surface during second plating, the invention enables different metallic colors to be applied to different surfaces without interference, thus achieving color variety while managing manufacturing complexity through systematic segmentation of the plating operations.
Solution Approach 2:
The patent applies preliminary underplating to the entire surface of the garment accessory before performing selective plating on front and back surfaces. This preliminary action creates a uniform base layer that prevents direct contact between the plating solution and the base material on surfaces that should not be plated, thereby enabling subsequent selective plating operations to achieve different colors on different surfaces without requiring complex masking arrangements during the underplating stage.
2Adaptability or versatility
If masking is applied to achieve different colors on front and back surfaces through conventional plating, then reversible design with different colors is possible, but the process becomes labor-intensive and costly due to multiple masking and demasking steps
Solution Approach 1:
The patent performs preliminary underplating on the entire surface before selective plating operations. This preliminary action ensures that all surfaces have a protective base layer, allowing the invention to subsequently apply different metallic colors to front and back surfaces through selective plating without risking direct contact between the plating solution and the base material. This approach enables reversible design capability while reducing the need for extensive masking and demasking operations, thereby improving production efficiency.
3Manufacturing precision
If full surface plating is performed on garment accessories like shell caps, then uniform metallic color is achieved, but cost increases unnecessarily since only the outside surface needs to be colored for aesthetic purposes
Solution Approach 1:
The patent applies different treatments to different regions of the garment accessory based on functional and aesthetic requirements. The outside surface receives metallic color plating to achieve the desired aesthetic appearance, while the inside surface receives only the thin underplating layer without the additional metallic color plating. This local differentiation achieves color uniformity on the visible outside surface while avoiding unnecessary plating costs on the hidden inside surface, thereby improving cost effectiveness.

AI summary
There is provided a method for subjecting garment accessories to a surface electrolytic treatment, which can advantageously provide various metallic colors to metallic garment accessories in a cost effective manner. The method can provide a first metallic color on one side of outer surface of the garment accessory while at the same time providing a second metallic color on the other side of the outer surface, by placing one or more metallic garment accessories in an electrolytic solution in a non-contact state with an anode and a cathode for passing electric current through the electrolytic solution, passing electric current through the electrolytic solution and generating a bipolar phenomenon on the garment accessory. The method may further comprise the step of controlling the posture of the garment accessory such that the one side of the outer surface of the garment accessory faces the anode and the other side faces the cathode during passing electric current through the electrolytic solution. The method may further comprise the step of polishing at least a part of the outer surface of the garment accessory during passing electric current through the electrolytic solution.
