Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a static magnetic stripe is used on the card, then the card structure is simple and manufacturing is easy, but the card cannot provide dynamic data communication and is susceptible to errors in data reading
Solution Approach 1:
The patent applies a dynamic magnetic stripe that can change its magnetic encoding state based on commands received from a remote server. The magnetic stripe transitions from a static structure to a dynamic one that can rewrite its data, allowing it to provide updated payment information, dynamic barcodes, and changing magnetic patterns to prevent copying and enhance security. This dynamic capability resolves the contradiction by improving data reading accuracy through updated information while managing complexity through programmed control rather than physical complexity.
Solution Approach 2:
The patent introduces a remote server as an intermediary that controls the dynamic magnetic stripe. The server receives commands, processes them, and sends back encoded magnetic patterns for the stripe to display. This intermediary system allows the card itself to remain relatively simple while the remote server handles the complexity of data management, updates, and security protocols, thereby improving reliability without proportionally increasing card complexity.
2Adaptability or versatility
If multiple output devices and input devices are integrated into the card, then the card provides advanced payment features and real-time data updates, but the device complexity increases significantly
Solution Approach 1:
The patent implements a multi-functional card system where a single card integrates multiple output devices (dynamic magnetic stripe, display, barcode) and input devices (touchscreen, RFID, magnetic stripe reader). These components work together to provide diverse payment features including contactless payment, swiping, display of dynamic information, and receipt generation. The universality principle allows one card to perform multiple functions that traditionally required separate devices, thereby improving versatility while managing complexity through integration rather than separate components.
Solution Approach 2:
The patent merges multiple communication and display functions into a single integrated card system. The dynamic magnetic stripe, display screen, barcode generator, RFID reader, and processor are combined into one unified device that can perform various payment operations. This merging reduces the need for multiple separate devices and cards, improving versatility while the integrated architecture manages complexity through centralized processing and coordinated operation of combined components.
3Reliability
If the card includes a processor and multiple communication devices, then real-time data updates and secure transactions are enabled, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent incorporates a processor that performs preliminary security actions before transactions occur. The processor verifies card authenticity, checks for tampering, validates encryption keys, and prepares secure data packets before they are transmitted. This preliminary action by the integrated processor ensures transaction security is built-in from the start, improving reliability while the processor's pre-programmed security protocols simplify manufacturing compared to building security into each individual component.
Solution Approach 2:
The patent replaces traditional mechanical card reading methods with electronic and electromagnetic systems. Instead of relying solely on physical magnetic stripe contact, the card uses RFID wireless communication, dynamic magnetic encoding, and electronic display systems. This substitution of mechanical systems with electronic ones improves transaction security through encryption and digital verification while the integrated processor manages the complexity of coordinating multiple communication protocols, making the system manufacturable as a unified electronic device rather than multiple mechanical components.
