Metal Chip Card Connector Assembly for Secure Automated Soldering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Memory card reading terminals face manufacturing complexity and increased costs due to the need for multiple manual assembly steps in securing the memory card reader, which is a weak link in terminal security, especially against attacks aiming to access the memory card connector.
Innovation Solution
A memory card reader body with a metal base and cover forming side walls of a rectangular parallelepiped shape, allowing for automated assembly and welding onto a motherboard without manual intervention, reducing the number of assembly operations and enhancing security through metal construction and electromagnetic interference protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple manual assembly steps are used to secure the memory card reader, then security protection is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent combines the memory card reader body with the motherboard by integrating the reader body as a through-hole structure that passes through the motherboard, allowing the connector to be directly accessible from the rear side. This merging eliminates the need for separate assembly steps and reduces manufacturing complexity while maintaining security protection through the integrated structure.
Solution Approach 2:
The memory card reader is divided into two main parts: the reader body (housing) and the connector, which are positioned at different locations. The reader body is integrated into the motherboard as a through-hole, while the connector is separately positioned at the rear side, allowing for simplified assembly and reduced manufacturing complexity.
2Reliability
If multiple manual assembly steps are used to secure the memory card reader, then security protection is improved, but manufacturing time and cost increase
Solution Approach 1:
The integrated through-hole structure allows the memory card reader body to be combined with the motherboard in a single assembly operation, eliminating multiple manual assembly steps. This merging significantly reduces manufacturing time and improves productivity while maintaining the security protection function.
3Reliability
If metal parts are added for protection, then security against electrostatic discharge and wear is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies metal parts specifically at critical locations where protection is needed, such as the connector components that are subject to wear and electrostatic discharge. This localized application of metal materials provides necessary protection while minimizing the overall addition of complexity to the device.
4Manufacturing precision
If manual soldering is used for assembly, then assembly precision is improved, but manufacturing time and cost increase
Solution Approach 1:
The integrated through-hole structure allows the memory card reader body to be combined with the motherboard in a single assembly operation, eliminating multiple manual assembly steps. This merging significantly reduces manufacturing time and improves productivity while maintaining the security protection function.
