Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Memory card reader terminals face security vulnerabilities due to the memory card connector being a weak link, with existing security measures increasing manufacturing complexity and cost, and making maintenance difficult.
Innovation Solution
A memory card reader body with a housing for the connector that integrates conductive tracks for protection, eliminating the need for external protective components and simplifying assembly by fixing the connector to the PCB before attaching the reader body, which covers and protects the connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external protective components (lattice, metal parts) are added to protect the memory card connector, then security against penetration and electrostatic discharge is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent integrates the protective lattice directly into the PCB substrate, merging the protective function with the existing structural component. This eliminates the need for separate external protective components, thereby reducing device complexity and manufacturing steps while maintaining security against penetration and electrostatic discharge
Solution Approach 2:
The protective lattice is formed using conductive material integrated into the PCB structure, creating a composite structure that combines the mechanical support function of the PCB with the protective function of the conductive lattice. This integrated approach simplifies manufacturing compared to assembling separate protective components
2Reliability
If multiple protective components and staggered welding steps are implemented, then security protection is improved, but ease of manufacture deteriorates
Solution Approach 1:
The protective lattice is integrated directly into the PCB manufacturing process, merging multiple functions (structural support, electrical connection, protection) into a single component. This eliminates the need for separate protective components and reduces the number of manufacturing steps, thereby improving ease of manufacture while maintaining protection
3Reliability
If numerous protective steps and components are added, then security is improved, but ease of repair deteriorates
Solution Approach 1:
By integrating the protective function directly into the PCB structure, the patent creates a unified component that is easier to diagnose and replace as a single unit. This eliminates the complexity of maintaining multiple separate protective components, thereby improving ease of repair while maintaining security
