Modular External Storage with Expansion Slot for SSD Upgrade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
External storage devices have fixed capabilities, such as storage capacity and data transfer rates, which limit their functionality and compatibility with host computing devices, requiring replacement to upgrade performance.
Innovation Solution
A modular storage system with an expansion slot for removable cards, allowing the integration of higher-speed storage devices like SSDs, which can provide faster read/write times and be presented as a single storage device to the host computing device, enabling data transfer through interfaces like USB 3.0 or Thunderbolt 2, and allowing selective data transfer to either the HDD or SSD based on speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-capability storage device is used, then the device structure is simple, but the adaptability and performance are limited
Solution Approach 1:
The storage device is divided into a host unit and detachable expansion cards. Each expansion card contains a storage device and controller that can be independently inserted or removed from expansion slots on the host unit, allowing flexible configuration of storage capabilities without redesigning the entire device.
Solution Approach 2:
The host unit is designed with universal expansion slots that can accommodate different types of expansion cards with various storage devices (e.g., SSDs, HDDs, flash memory). This multi-functional design allows a single host unit to support multiple storage configurations and performance levels.
2Speed
If a high-speed storage device is integrated, then the data transfer rate is improved, but the device complexity increases
Solution Approach 1:
The system allows dynamic selection of storage performance by enabling or disabling expansion cards as needed. Users can configure the device to use high-speed storage when needed and revert to simpler configurations when high speed is not required, making the complexity adjustable rather than fixed.
Solution Approach 2:
The host unit acts as an intermediary between the high-speed storage devices on expansion cards and the host computing device. The host unit's controller manages data transfer and device presentation, allowing high-speed storage to be integrated without requiring the host computing device to directly support each storage device.
3Quantity of substance
If multiple storage devices are integrated, then the storage capacity and functionality are enhanced, but the device complexity increases
Solution Approach 1:
Multiple storage devices are segmented into separate expansion cards rather than being integrated into a single unit. This allows each storage device to be independently managed, installed, and removed, simplifying the overall system architecture while maintaining the ability to provide large total storage capacity through multiple cards.

AI summary
Provided is an apparatus including a first storage device. The apparatus also includes an expansion slot configured to receive a removable card with a second storage device. The removable card with the second storage device is configured to provide faster read/write times to the second storage device than read/write times of the first storage device. The first and second storage devices are seen as a single storage device by a host computing device.
