Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional magnetic stripe or IC card technology is used, then data storage capacity is limited (553 bits, 200 bits, 535 bits for magnetic stripe; 1 MB for IC cards), but the patent achieves over 10 MB storage capacity
Solution Approach 1:
The patent combines multiple functional components into a single credit card structure: a 10 MB+ flash memory chip for data storage, Bluetooth transceiver for wireless communication, rechargeable battery for power supply, and power management circuitry. This merging enables the card to function as both a payment instrument and a portable data storage device with wireless connectivity, resolving the contradiction between increased storage capacity and device complexity.
2Speed
If contactless IC card technology operating at 13.56 MHz is used, then data exchange rate is limited to about 106 kilobits per second at distances less than 10 centimeters, but the patent achieves faster Bluetooth data transmission over distances up to 30 meters
Solution Approach 1:
The patent equips the credit card with a Bluetooth transceiver that enables universal wireless communication compatibility with smartphones, tablets, laptops, and other Bluetooth-enabled devices. This eliminates the requirement for specialized contactless readers, allowing the card to transmit data at Bluetooth speeds (significantly faster than 106 kbps) over distances up to 30 meters, thereby achieving both high transmission speed and broad adaptability.
3Length of stationary object
If proximity cards operating at larger distances up to 1.5 meters are used, then magnetic field strength is much smaller, reducing the data transfer rate to only small amounts of information
Solution Approach 1:
The patent replaces the magnetic field-based proximity card communication system with Bluetooth radio frequency communication. This substitution enables the card to maintain high data transfer rates over extended distances up to 30 meters without being constrained by magnetic field strength limitations, thereby achieving both long communication distance and high productivity in data transfer.
4Quantity of substance
If smart cards with integrated circuits are used, then data storage capacity reaches about 1 MB, but the patent achieves over 10 MB storage capacity with secure data transmission
Solution Approach 1:
The patent increases the flash memory storage capacity from the traditional 1 MB IC card standard to over 10 MB by utilizing modern high-capacity flash memory chips. Additionally, it implements enhanced security measures including encryption algorithms and secure boot procedures to protect the larger storage capacity, thereby achieving both increased data storage capacity and maintained/improved data security reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables secure and efficient transmission of large data volumes, such as personal health records, over extended distances using Bluetooth technology, ensuring secure data integrity and authenticity, and providing a convenient, portable solution for medical emergencies and other applications.
Implementation Method 1
communicate using Bluetooth at significantly faster data speeds... Bluetooth is a ubiquitous non-contact communication interface... operate at a distance of less than about 10 centimeters from the reader
Implementation Method 2
powered by rechargeable batteries and equipped with advanced power management
Implementation Method 3
These cards obtain electric power from the reader as magnetic radiation, and the coil in the card converts this to current to power the electronic circuits in the card
Data Source
AI summary
A smart card is disclosed which includes a mass storage memory for storing biometric information of a user and private data. A radio is used as an interface to the card. When the user of the card wishes to invoke an application for the private data, biometric information about the user is provided to a device in communication with the card, enabling the card to authenticate the user as an authorized user of the private data, and in response to that authentication provide the data to the application in a manner that maintains privacy and integrity of data.
