Hybrid Interface Socket for SSD and SD Card Upgrades
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of component parts into miniaturized electronic systems often leads to inconvenient and costly upgrades for storage capacity, as users must replace integrated components to accommodate increased storage, degrading user experience and increasing system costs.
Innovation Solution
An electronic system with a hybrid interface socket that supports both SD and SSD cards, allowing for convenient storage capacity upgrades and efficient space utilization by sharing power terminals and using USB bridge chips for SD cards, while direct connections via SATA or PCI standards for SSD cards maintain high communication speeds.

Engineering Contradiction Analysis
1Volume of moving object
If component parts are integrated into unibody systems for miniaturization, then system compactness is improved, but storage capacity upgradeability deteriorates
Solution Approach 1:
The storage system is segmented into a fixed integrated portion (unibody) and a removable modular portion (SSD card). This allows the main system to remain compact while enabling easy replacement and upgrading of the storage card module independently, resolving the contradiction between compactness and upgradeability.
Solution Approach 2:
The hybrid interface socket is designed with universal compatibility to accept both SD cards and SSD cards. This multi-functionality allows the same physical interface to support different storage types and capacities, enabling upgradeability without compromising the compact integrated design.
2Adaptability or versatility
If traditional SD card interfaces are used, then compatibility is improved, but communication speed deteriorates
Solution Approach 1:
A USB bridge chip is introduced as an intermediary component in the hybrid interface socket. This bridge chip enables SD cards to communicate through USB protocols, significantly improving communication speed while maintaining backward compatibility with SD card formats.
Solution Approach 2:
The interface protocol parameters are changed by supporting multiple protocols (SD protocol and USB protocol) within the same hybrid interface socket. This allows the system to automatically select appropriate communication parameters based on the inserted card type, achieving both compatibility and high speed.
3Adaptability or versatility
If separate interfaces for SD and SSD cards are provided, then functionality is improved, but device complexity deteriorates
Solution Approach 1:
The SD card interface and SSD card interface are merged into a single hybrid interface socket. This integration allows both interface types to coexist in one physical structure, reducing the number of separate components and simplifying the overall device structure while maintaining full functionality for both card types.

AI summary
Provided are a solid state drive (SSD) card and an electronic system including the same. The electronic system includes a main board to which an input device and an output device are connected. A central processing unit (CPU) and a platform hub (PH) are provided on the main board. The PH is electrically connected to a hybrid interface socket. The hybrid interface socket includes a secure digital (SD) card interface and a non-SD card interface. When the SSD card and the electronic system including the same are used, a storage capacity may be conveniently upgraded to a higher capacity. Also, since the hybrid interface socket is provided in place of a conventional SD card socket, additional space is not required and thus space may be efficiently used.
