Memory Card Socket Movable Inner Case Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Memory cards are susceptible to data damage due to sudden power off or sudden power loss situations during disconnection from a host device, which can lead to data corruption or loss.
Innovation Solution
A memory card socket with a movable inner case, a locking mechanism, and a sensor-release signal system that generates a sense signal upon withdrawal, allowing for controlled release of the locking mechanism to prevent sudden power disruptions by transmitting a release signal to the host device, ensuring safe disconnection and preventing data loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the memory card is disconnected from the host, then the memory card can be removed or replaced, but data in the memory card may be damaged due to sudden power off or sudden power loss
Solution Approach 1:
The locking mechanism is activated in advance before the memory card is fully removed. When the memory card is detected to be in the removal process, the locking portion engages to maintain electrical connection, ensuring power supply continues until the removal is complete, thus preventing sudden power loss and data damage
Solution Approach 2:
The locking mechanism provides a counter-action to the removal force by engaging and holding the inner case in position. This preliminary anti-action prevents the inner case from moving outward during memory card removal, thereby maintaining stable electrical connection and preventing sudden power off that would damage data
2Reliability
If a locking mechanism is added to prevent sudden power off, then data integrity is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is merged with the existing inner case structure. The locking portion is integrated into the inner case as a unified component, combining the case structure with the locking function, thereby reducing overall device complexity while maintaining data integrity
Solution Approach 2:
The locking mechanism operates automatically based on the position of the memory card. When the memory card is inserted, the locking portion automatically engages; when the memory card is removed, the locking portion automatically releases. This self-service operation eliminates the need for additional control systems, reducing device complexity while ensuring data integrity

AI summary
A memory card socket is provided. The memory card socket includes an outer case, an inner case which is movable within the outer case and includes a slot into which a memory card is insertable. The memory card socket also includes a locking portion which locks the inner case to the outer case upon a withdrawal of the memory card.
