Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual-interface transaction cards have limited appearance patterns, poor tactile experience, and are difficult to customize, making them less competitive in the market.
Innovation Solution
A transaction card with a 3D printing graphic surface, featuring a card base structure that includes a front and back 3D printing graphic layer with a height of 0.05-0.46mm, allowing for enhanced tactile experience and customizable designs, using a 3D printer like the VGD610UV-MVP with six-color UV ink.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional silk-screen printing or lithographic printing is used for card graphics, then the printing process can be completed, but the graphic surface remains plane with poor tactile experience and limited design flexibility
Solution Approach 1:
The patent applies 3D printing technology to create raised graphic surfaces with heights of 0.05-0.46mm, transforming traditional 2D plane graphics into 3D tactile surfaces. This dimensional change provides enhanced tactile experience and visual depth while enabling complex designs that cannot be achieved with conventional printing methods.
Solution Approach 2:
The patent replaces traditional mechanical printing processes (silk-screen printing requiring screen-stretching, lithographic printing requiring PS version preparation) with 3D printing technology. This substitution eliminates complex preparatory work and directly creates three-dimensional graphics through additive manufacturing, simplifying the manufacturing process while enhancing graphic dimensionality.
2Adaptability or versatility
If traditional printing methods are used, then the card can be produced efficiently, but the appearance patterns are single and market competitiveness is poor
Solution Approach 1:
The patent enables dynamic and customizable card designs through 3D printing technology, allowing appearance patterns to be easily modified and customized without retooling. The digital nature of 3D printing allows for rapid design changes and personalization, providing diverse appearance patterns while maintaining production efficiency through automated printing processes.
3Ease of operation
If 3D printing graphic layer is added to the card surface, then tactile experience and design flexibility are improved, but the card structure becomes more complex
Solution Approach 1:
The patent merges the graphic layer with the protective film layer into a single integrated structure. The 3D printing graphic layer is applied directly on the protective film layer, combining graphic functionality with protective functionality in one layer, thereby reducing overall structural complexity while maintaining tactile experience and design flexibility.
