Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple physical credit cards are carried to support different payment systems, then payment system compatibility is improved, but portability and convenience deteriorate
Solution Approach 1:
The patent combines multiple credit card functions into a single portable electronic device. The device stores personal information from multiple credit card companies and can switch between different payment systems, eliminating the need to carry multiple physical cards while maintaining compatibility with various payment networks.
Solution Approach 2:
The portable electronic device is designed to perform multiple functions: it can store personal information from different credit card companies, generate security codes for various payment systems, and interface with multiple payment networks. This multi-functionality allows a single device to replace multiple specialized credit cards.
2Productivity
If personal information is stored in a centralized database for easy access, then information retrieval efficiency is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The system segments personal information into multiple encrypted files stored in the portable electronic device. Each file is protected by separate security codes, and the information is distributed across different storage locations within the device, making unauthorized access difficult while allowing efficient retrieval through the code generator.
Solution Approach 2:
The portable electronic device acts as an intermediary between the user and the centralized database. It retrieves information through bidirectional verifying communication and provides it to the user in encrypted form, eliminating the need for direct database access while maintaining security. The device generates security codes that mediate the authentication process.
3Reliability
If security codes are generated and stored for each credit card company, then payment security is improved, but device complexity increases
Solution Approach 1:
The portable electronic device includes an automatic code generator that creates security codes as needed without requiring manual input or management by the user. The device self-manages the storage, retrieval, and generation of security codes for different credit card companies, reducing user burden while maintaining high security standards.

AI summary
A portable electronic card system and a verifying method thereof are provided. The portable electronic card system includes: a portable personal electronic device, a rewritable card, and a writing device. The portable personal electronic device is used for obtaining a certificated code and a personal information from a remote controller. When a bidirectional verifying communication is performed between the remote controller and the portable electronic device to download the personal information, security code stored in the rewritable card be compared with security code stored in the portable electronic device for verifying and writing the personal information into the rewritable card, and another security code is generated to update or replace the original security code stored in the portable electronic device and the rewritable card.
