Memory Card Cover with Soldered Grounding Tips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Memory cards used in vehicles to store sensor data are prone to data corruption or loss due to vibrations during regular use or accidents, and there is a need to prevent unauthorized access and modification of this data.
Innovation Solution
An apparatus with a cover mechanism that securely encloses the memory card, providing electrical connection and using soldering tips for grounding to prevent discharge, along with anti-tamper features like seals and labels, to maintain data integrity and restrict access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the memory card is left exposed for easy access, then ease of operation is improved, but data security and integrity deteriorate due to unauthorized access and vibration exposure
Solution Approach 1:
The device is segmented into multiple functional components: a removable memory card for data storage, a protective cover with hinge mechanism for controlled access, and a circuit board with dedicated slots. This segmentation allows the memory card to be easily inserted and removed while the cover provides continuous protection when closed, resolving the contradiction between accessibility and data integrity.
Solution Approach 2:
The cover is designed to be closed and secured before the device is subjected to vibrations or potential unauthorized access. This preliminary protective action ensures that the memory card is already protected when the device is in use or during transport, preventing data corruption before it can occur.
2Reliability
If the cover is made secure with anti-tamper features, then data security is improved, but device complexity increases
Solution Approach 1:
Anti-tamper features such as tamper-evident seals and security labels are extracted as separate, attachable components rather than being integrated into the cover structure itself. This allows the cover to remain relatively simple while still providing enhanced security through these additional protective elements that can be applied without redesigning the entire cover mechanism.
Solution Approach 2:
Instead of making the entire cover complex, security features are applied locally at critical points: tamper-evident seals at the hinge connection, security labels on the cover surface, and grounding contacts at specific electrical connection points. This localized approach provides adequate security without requiring the entire cover mechanism to be overly complex.
3Reliability
If soldering tips are added for grounding, then protection against electrical discharge is improved, but manufacturing complexity increases
Solution Approach 1:
The soldering tips for grounding are merged with the existing electrical connection structure of the circuit board. Rather than being separate components requiring additional assembly steps, the grounding contacts are integrated into the slot design that already provides electrical connections to the memory card, thereby providing electrical discharge protection without significantly increasing manufacturing complexity.

AI summary
Apparatuses for securing a memory card. One example apparatus can include a slot coupled to a printed circuit board (PCB), wherein the slot is configured to receive a memory card to provide electrical connection between the PCB and the memory card and a cover coupled to the PCB and configured to enclose the memory card when in a closed position and maintain electrical connection between the memory card and the PCB when in the closed position.
