Rollable Payment Card Design for Flexible Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional payment cards are rigid and inflexible, limiting their storage and portability options and restricting the ability to change their appearance or display real-time information.
Innovation Solution
A rollable payment card with a verification element, processor, electronic display unit, and power element, allowing it to shift between flat and rolled configurations, enabling customizable display and enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional payment cards are made rigid for durability and structural integrity, then strength and reliability are improved, but flexibility and storage portability deteriorate
Solution Approach 1:
The payment card incorporates flexible materials and a flexible display unit that allow the card to dynamically change its shape between flat and rolled configurations, enabling it to adapt to different storage conditions while maintaining structural integrity
Solution Approach 2:
The card uses flexible substrates and thin-film construction throughout, including flexible circuit boards and flexible display units, allowing the entire card structure to bend and roll without damage while maintaining durability
2Ease of manufacture
If printed designs are used on conventional cards for customization, then manufacturing simplicity is improved, but adaptability and real-time information display deteriorate
Solution Approach 1:
The payment card incorporates a flexible display unit that can dynamically change its content to display different information such as account balances, expiration dates, and personalized messages, allowing real-time customization without remanufacturing
Solution Approach 2:
Instead of printing static designs, the card uses a display unit that can electronically replicate and present different visual information on demand, enabling unlimited customization of the card's appearance and information content

AI summary
A rollable payment card is shiftable between a flat configuration and a rolled configuration via a manual rolling process. The payment card comprises a verification element, a processor, an electronic display unit in communication with the processor, and a power element providing electrical power to the display unit. The electronic display unit includes an electronic display region configured to display an image. The electronic display region is manually rollable. The payment card in the flat configuration presents horizontally spaced apart first and second ends and vertically spaced apart top and bottom edges. The first end overlaps the second end during the course of the rolling process, with the first end being disposed arcuately past the second end when the payment card is in the rolled configuration.
