Virtual USB Stick Memory Partitioning for Multi-Device Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The handling of USB sticks for various applications across different electronic devices is cumbersome due to the need for multiple formats and configurations, especially for service technicians as the range of applications expands.
Innovation Solution
The creation of virtual USB sticks on a single USB stick, each configured for specific applications or devices, with a touch screen for user-friendly selection and password-protected configuration, allowing different memory areas to be formatted as needed for compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate USB sticks are used for different applications and devices, then each device can have optimized formatting and configuration, but the handling and management becomes cumbersome and complex
Solution Approach 1:
The patent combines multiple virtual USB sticks into a single physical USB stick. The memory device is divided into multiple memory areas, each formatted for different applications (e.g., FAT32 for Windows, ext4 for Linux), allowing one physical stick to serve multiple devices and purposes simultaneously, eliminating the need to manage multiple separate sticks
Solution Approach 2:
The USB stick is designed with multi-functionality by implementing multiple memory areas with different formatting options within a single device. This allows the same USB stick to be universally compatible with various electronic devices and operating systems without requiring separate specialized sticks for each application
2Adaptability or versatility
If memory areas are formatted differently for different devices, then compatibility with various devices is improved, but the risk of accidental data loss or modification increases
Solution Approach 1:
The memory device is segmented into multiple independent memory areas, each with its own formatting (FAT32, ext4, etc.). Each memory area can be independently mounted or unmounted by the host system, allowing the system to access only the appropriately formatted area for the current device, thereby protecting data in other areas from accidental modification or loss
Solution Approach 2:
The patent introduces a configuration file system that acts as an intermediary layer between the host system and the multiple memory areas. This configuration system manages the mounting and unmounting of appropriate memory areas based on the host device type, preventing direct access to incompatible or unrelated memory areas and thus protecting data integrity
3Ease of operation
If configuration mode is accessible without restrictions, then ease of operation is improved, but the risk of unauthorized changes to memory configuration increases
Solution Approach 1:
The system performs preliminary authentication checks before allowing access to configuration mode. A password protection mechanism is implemented that must be satisfied before any configuration changes can be made. This preliminary security measure ensures that only authorized users can modify memory area configurations, while still allowing easy access for authenticated users
