Remote Data Storage Access via Network Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable devices like mobile phones often lack compatible memory device connectors, such as USB connectors, making it inconvenient to transfer data to or from these devices, which have limited memory for storing media content.
Innovation Solution
A system and method that enables data transfer between a data storage device, like a USB flash drive, and any host device connected to a network, allowing remote access and transfer of data through a host device, even if the portable device lacks a compatible connector, by using a relay server to facilitate communication between the host device and the portable device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If portable devices use limited onboard memory for storage, then device portability and simplicity are improved, but data storage capacity and accessibility are worsened
Solution Approach 1:
The patent implements a nested architecture where a portable data storage device (USB flash drive) is coupled to a host device (personal computer), which is connected to a network (Internet). This nested structure allows the small portable device to leverage the larger storage and network capabilities of the host and network infrastructure, effectively expanding storage capacity while maintaining device portability.
Solution Approach 2:
The host device acts as an intermediary between the portable storage device and remote devices. The host device receives data from the portable storage device, manages the data, and facilitates transfer to remote devices over the network. This intermediary approach allows portable devices to access remote storage resources without requiring direct connection or large onboard memory.
2Adaptability or versatility
If portable devices lack common memory device connectors, then device design flexibility is improved, but data transfer convenience is worsened
Solution Approach 1:
The host device serves as an intermediary that bridges the gap between portable devices without common connectors and data storage devices. The host device has both network connectivity and USB ports, allowing it to receive data from portable devices and transfer it over the network to remote devices, eliminating the need for direct physical connection between incompatible devices.
Solution Approach 2:
The host device performs multiple functions: it acts as a USB host for connecting portable storage devices, a network gateway for internet connectivity, and a data management system for coordinating transfers. This multi-functionality allows the system to accommodate various device types with different connectors while maintaining data transfer capability.
3Speed
If data storage devices are directly connected to portable devices, then data transfer speed is improved, but device compatibility and remote accessibility are worsened
Solution Approach 1:
The host device acts as an intermediary that maintains fast local data transfer between the portable storage device and itself, then uses network communication for remote transfers. This approach preserves high-speed access when devices are physically connected while enabling remote accessibility through the network, balancing both requirements.
Solution Approach 2:
The data transfer process is segmented into two distinct phases: local high-speed transfer from the portable device to the host device over USB, and remote transfer from the host device to remote devices over the network. This segmentation allows each transfer to use the most appropriate communication channel for its requirements.
Data Source
AI summary
A method may be performed in a data storage device that stores one or more files and that is operatively coupled to any host device that is accessible to another device via a network. The method includes receiving an access request originating from the other device. The access request is received via a particular host device registered as a recipient of requests for access to the data storage device via the network while the data storage device is operatively coupled to the host device and while the host device is accessible via the network. The method also includes, in response to receiving the access request, sending a response with access information to the other device. The response is provided to the particular host device to be sent to the other device via the network.
