Memory Card Wireless File Access via Embedded Web Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in accessing digital files on memory cards with wireless communication capabilities due to the need for additional 'apps' on their devices, which may not be compatible or cost-prohibitive, and these apps often do not enable full feature utilization.
Innovation Solution
A memory card with a central processor, storage module, and wireless transceiver module that provides a graphical user interface on connected devices, allowing a designated master device to control access and viewing of digital files across multiple wireless communication devices without the need for additional apps, using authentication methods like passwords or MAC address matching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional apps are installed on wireless communication devices to access digital files on memory cards, then file access capability is improved, but device complexity and user burden increase
Solution Approach 1:
The patent extracts the file access control functionality from the wireless communication devices and relocates it to the memory card itself. The memory card's central processor handles authentication, file selection, and access control, eliminating the need for complex apps on connected devices. This is achieved by implementing a web-based interface that runs on the memory card's embedded web server, allowing direct interaction with stored files without external application software.
Solution Approach 2:
The memory card is designed with universal compatibility to work with multiple types of wireless communication devices (smartphones, tablets, computers) without requiring device-specific applications. The central processor provides a standardized web-based interface that can be accessed through any device with a web browser, making the memory card universally accessible across different platforms and operating systems.
2Adaptability or versatility
If apps are used to access digital files on memory cards, then file access is enabled, but compatibility and cost issues arise
Solution Approach 1:
The patent introduces an embedded web server and web-based graphical user interface as an intermediary between the memory card and wireless communication devices. This web interface acts as a universal mediator that can be accessed through any device with a web browser, eliminating compatibility issues with native apps. The web interface handles file browsing, selection, and transfer operations, providing a consistent user experience across different device types without requiring device-specific applications.
3Adaptability or versatility
If apps are installed to access all features of memory cards, then feature access is improved, but users may not have compatible operating systems or wish to incur additional expenses
Solution Approach 1:
The memory card provides self-service functionality by hosting its own web-based interface and handling all file access operations independently. The central processor on the memory card manages authentication, file selection, and data transfer without requiring external application software on the connected devices. This self-contained approach allows full feature access through a universal web browser interface, eliminating operating system compatibility requirements and additional app installation costs for users.
