Modular PCB Memory Connector for SSD Capacity Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in data storage devices, such as SSDs, is the need for increased memory capacity without the expense and physical limitations of replacing the entire device, as higher capacity SSDs can be costly and physically restrictive.
Innovation Solution
A removably couplable flash memory printed circuit board (PCB) system that allows for the replacement of a smaller or same-sized PCB with a larger capacity PCB, using connectors to establish communication between the processor and non-volatile memory, enabling easy expansion of memory capacity without replacing the entire data storage device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the entire data storage device is replaced to increase memory capacity, then the storage capacity is improved, but the cost increases and physical space constraints are not addressed
Solution Approach 1:
The data storage device is divided into separable components: a controller board and a memory board connected via a connector. This segmentation allows the memory board to be replaced independently to upgrade capacity without replacing the entire device or the controller board, thereby reducing cost while maintaining functionality.
Solution Approach 2:
The connector is designed with universal compatibility to work with different memory board configurations and capacities. This multi-functionality enables the same controller board and connector to support various memory upgrades, allowing capacity expansion without requiring a completely new device design.
2Quantity of substance
If a larger capacity SSD is purchased, then the storage capacity is improved, but the physical size is limited by the installation space
Solution Approach 1:
By separating the memory component from the controller, the memory can be upgraded to higher capacity versions that fit within the same physical footprint. The memory boards are designed to be interchangeable within the same form factor, enabling capacity increases without increasing the device's external dimensions.
Solution Approach 2:
The solution transitions from increasing capacity through external device size to increasing capacity through internal component density and configuration. Memory boards with different capacities can be designed to fit the same physical space by optimizing the layout and arrangement of memory chips on the board.
3Quantity of substance
If the entire data storage device is replaced to increase memory capacity, then the storage capacity is improved, but device complexity and installation requirements increase
Solution Approach 1:
The device is segmented into modular components with standardized interfaces. The memory board is a self-contained module that can be replaced without affecting other components, simplifying the upgrade process and reducing the complexity of installation compared to replacing an entire integrated device.
Solution Approach 2:
The connector serves as an intermediary component that standardizes the interface between the controller board and memory boards. This standardized intermediary simplifies the replacement process by providing a uniform connection mechanism that works across different memory capacity variants.
