Solution Overview
Problem
Conventional transaction cards made of PVC plastic are not durable, prone to scratching and wear, and limited in achieving variations in physical properties such as weight, color, texture, and style, which restricts their mechanical and stylistic variability.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional PVC plastic material is used to manufacture transaction cards, then manufacturing cost is reduced and ease of manufacture is improved, but durability is worsened and resistance to scratching and wearing is reduced
Solution Approach 1:
The patent applies composite materials by combining PVC plastic substrate with metal plating layers (such as aluminum, copper, or nickel) and protective coatings. This creates a multi-layer composite structure where each material contributes its superior properties: the plastic provides flexibility and cost-effectiveness, while the metal layers provide durability, scratch resistance, and enhanced mechanical strength, thereby resolving the contradiction between ease of manufacture and durability.
Solution Approach 2:
The patent utilizes parameter changes by applying electrically applied coatings that modify the surface properties of the card without changing the bulk material properties. Through electrostatic deposition, electrophoretic deposition, or electroplating processes, the surface parameters such as hardness, scratch resistance, and wear resistance are significantly improved while maintaining the underlying plastic material's manufacturability and flexibility.
2Ease of manufacture
If conventional PVC plastic material is used to manufacture transaction cards, then manufacturing cost is reduced, but mechanical properties and stylistic variability are limited
Solution Approach 1:
By using composite materials with metal plating and various coating layers, the patent enables wide variability in mechanical properties while maintaining cost-effectiveness. The combination of different materials allows tuning of weight, strength, flexibility, and other mechanical properties without fundamentally changing the manufacturing process or substrate material.
Solution Approach 2:
The patent achieves stylistic and mechanical property variability through parameter changes in the coating process. By controlling coating thickness, material composition, and application methods, a wide range of visual appearances, textures, weights, and mechanical properties can be achieved from the same base plastic material, thereby resolving the limitation in adaptability.
3Reliability
If electrically applied coating is formed on electrically conductive surface, then durability and visual/tactile appeal are improved, but device complexity and manufacturing process complexity increase
Solution Approach 1:
The patent replaces traditional mechanical coating application methods with electrically applied coating processes such as electrostatic deposition, electrophoretic deposition, or electroplating. These electrical fields enable more uniform and controlled coating application, improving durability and surface quality while the automation of these processes actually reduces long-term manufacturing complexity despite the introduction of electrical equipment.
Solution Approach 2:
By utilizing parameter changes in the electrical coating process, the patent achieves consistent high-quality results that improve durability. The electrical parameters (voltage, current, time) can be precisely controlled to optimize coating properties, and once parameters are established, the process becomes highly repeatable and manageable, reducing operational complexity.
