Pivoting Shield Member for Secure Electrical Device Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical devices, such as memory cards, risk data corruption or storage medium damage when removed during active access, and existing protection mechanisms, like lids with sensors, may not adequately prevent premature removal.
Innovation Solution
An electrical component with a housing featuring a pivotally mounted shield member and a control system that releases the shield member only after communication idle, exposing an ejector to safely remove the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lid with sensor is used to cover the card slot, then data corruption is prevented by stopping access when lid is opened, but users can still remove the card prematurely and the protection is insufficient
Solution Approach 1:
A shield member is introduced as an intermediary component between the card slot and the external environment. The shield member includes a shield member control system that acts as a mediator to manage card ejection, ensuring data operations complete before removal. This additional control layer prevents premature card removal while maintaining user ability to eject cards when appropriate.
Solution Approach 2:
The shield member control system implements feedback mechanisms by monitoring the status of data operations and automatically controlling the shield member position accordingly. When data operations are active, the system provides feedback to maintain the shield in a blocking position; when operations complete, feedback allows the shield to move and permit card ejection.
2Productivity
If the shield member is released immediately when card is inserted, then card access is enabled quickly, but data corruption risk increases if card is removed during active operations
Solution Approach 1:
The shield member control system performs preliminary actions by automatically positioning the shield member to block the card slot upon card insertion. This preliminary blocking action prevents premature removal while the system initializes and begins data operations, ensuring data integrity is maintained from the moment of insertion until operations are complete.
Solution Approach 2:
The shield member is designed with dynamic positioning capability, allowing it to automatically transition between blocked and unblocked positions based on real-time operational status. This dynamic behavior enables the system to quickly enable card access when safe while automatically restricting access during critical data operations, balancing productivity and reliability.
3Reliability
If the shield member blocks the ejector continuously, then premature card removal is prevented, but card ejection is delayed until communication is idle
Solution Approach 1:
The shield member control system uses feedback from communication status monitoring to automatically control shield member positioning. When communication becomes idle, the system receives feedback and automatically moves the shield member to unblock the ejector, eliminating manual intervention delays while maintaining protection during active operations.
Solution Approach 2:
The shield member control system provides self-service functionality by automatically managing the shield member position based on communication status without requiring user input. The system autonomously blocks the ejector during active operations and automatically unblocks it when safe, reducing both premature removal risks and ejection delays caused by manual control.
