Solution Overview
Problem
Users face difficulties in managing and identifying data stored on multiple memory cards, as they need to physically insert each card into a host device to access or transfer data, which becomes cumbersome with increasing numbers of cards.
Innovation Solution
A memory device equipped with a wireless antenna and NFC controller that allows data exchange and management without physical connection, using Near Field Communication (NFC) standards to transmit and receive data between the memory device and a wireless communication host device, enabling data reading and writing without power from the host device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users physically insert memory cards into a host device to access or transfer data, then data can be read and written, but the operation becomes cumbersome and time-consuming when managing multiple memory cards
Solution Approach 1:
The patent replaces the mechanical insertion system with a wireless communication system. Instead of physically inserting memory cards into a host device, the system uses wireless communication (NFC and other wireless protocols) to enable data access and transfer. The wireless antenna and communication circuits allow the memory card to communicate with external devices without physical connection, eliminating the need for mechanical insertion and extraction operations.
2Adaptability or versatility
If users physically insert memory cards into a host device to transfer data, then data can be exchanged, but the process requires a host device to be available
Solution Approach 1:
The patent implements self-service capability by enabling the memory card to perform wireless communication independently. The memory card includes wireless communication circuits and antennas that allow it to exchange data with external devices directly, without requiring a host device. This enables the memory card to serve itself for data transfer operations, particularly useful in field conditions or when a host device is not available.
3Ease of operation
If a wireless antenna is added to the memory card to enable wireless communication, then data can be transferred without physical connection, but the device complexity increases
Solution Approach 1:
The patent achieves multi-functionality by integrating multiple communication capabilities into the memory card. The wireless communication system supports both NFC (Near Field Communication) for close-range communication and other wireless protocols for extended-range communication. This universal communication approach allows the memory card to operate in various scenarios (with host devices, without host devices, different communication ranges) using a single integrated wireless system, thereby managing complexity through functional consolidation.
