Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional personal cards made of plastic lack durability and security features, making them susceptible to counterfeiting and fraud.
Innovation Solution
A transaction card made from a solid block of precious metal alloy, such as gold, with engraved information on polished panels and a contrasting background design, incorporating a stone and security features like an EMV chip and magnetic strip, to enhance durability and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If personal cards are made from plastic, then they are easy to manufacture and inexpensive, but they lack durability and are susceptible to counterfeiting and fraud
Solution Approach 1:
The patent changes the material parameter from plastic to metal (precious metal alloy), fundamentally altering the physical properties of the card. This material substitution provides inherent durability, resistance to counterfeiting, and a prestigious appearance while maintaining manufacturability through specialized metalworking processes
Solution Approach 2:
The card combines multiple materials and features: precious metal alloy base material, engraved information, polished panels, contrasting background designs, and integrated security features. This composite approach creates a card that is both durable and highly secure against counterfeiting
2Reliability
If personal cards are made from metal, then they provide enhanced durability and security, but they increase manufacturing complexity and cost
Solution Approach 1:
The card surface is divided into distinct functional zones: polished panels for information display, contrasting background areas for visual distinction, and specific regions for engraved data. This segmentation allows each area to be optimized for its specific function while simplifying the overall manufacturing process through modular design
Solution Approach 2:
Different surface treatments are applied to different areas of the card: high polish finish on information panels for readability and aesthetic appeal, contrasting finishes on background areas for visual distinction. This local differentiation enhances both security and manufacturability by applying specific treatments only where needed
3Reliability
If information is engraved on the card, then security and authenticity are enhanced, but manufacturing time and complexity increase
Solution Approach 1:
Information is pre-engraved into the metal card during the manufacturing process before the card is issued to the customer. This preliminary action ensures that the engraved information is permanently integrated into the card structure, providing enhanced authenticity and security while being efficiently produced during initial manufacturing
