Portable Data Carrier Dual Interface Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable data carriers face limitations in data transmission rates when processing and returning large amounts of data, particularly in applications like digital television, where real-time data display is required, due to the constraints of existing interfaces.
Innovation Solution
Implementing a method that utilizes multiple interfaces for data communication between a portable data carrier and a data processing device, allowing data to be received via one or more receiving interfaces and sent back via one or more transmitting interfaces, thereby increasing the overall data transmission rate by aggregating the rates of individual interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single interface is used for data communication between the data carrier and the data processing device, then the device complexity is low, but the data transmission rate is insufficient for processing large amounts of data in real-time
Solution Approach 1:
The data communication path is segmented into multiple independent interfaces. The data carrier and data processing device each implement multiple separate interfaces (e.g., first interface and second interface) that operate in parallel, allowing data to be transmitted through multiple channels simultaneously, thereby increasing overall throughput without requiring a single complex high-speed interface
Solution Approach 2:
The data carrier is designed with multi-functional capability to support multiple interface types simultaneously. Each interface can handle data communication independently, and the system can dynamically select or combine interfaces based on data volume and speed requirements, providing universal adaptability for different data transmission scenarios
2Loss of time
If data is received and processed sequentially through a single interface, then the device complexity is low, but the time required to process and return large amounts of data is excessive
Solution Approach 1:
Multiple interfaces enable continuous data flow without interruption. While data is being received through one interface, processed data can simultaneously be transmitted back through another interface, eliminating idle waiting time and maintaining continuous productive action throughout the data processing cycle
Solution Approach 2:
The system prepares multiple communication paths in advance before data transmission begins. The data carrier and data processing device are pre-configured with multiple interfaces ready to operate, allowing immediate parallel data exchange without sequential setup delays
3Productivity
If a single interface is used for both receiving and transmitting data, then the device complexity is low, but the data transmission rate for bidirectional communication is limited
Solution Approach 1:
The communication architecture transitions from a single-dimensional sequential interface to a multi-dimensional parallel interface structure. Data can flow in multiple directions simultaneously through different interfaces, adding spatial dimensionality to the data transmission paths and enabling concurrent bidirectional communication

AI summary
The method involves receiving data by data processing device and working on the received data. The data is received over two receiving interfaces of a data medium. The working data is sent back over two transmission interfaces of the data medium. The data is received over a Universal serial bus (USB)interface or a Single wireless protocol (SWP)interface. Independent claims are included for the following: (1) a portable data medium with two interfaces for data communication; (2) a data processing device with write or read device for receiving portable data medium; and (3) a system with a data processing device.
