Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission methods between secure and insecure data processing systems are complex and vulnerable to hacker attacks and malware transmission, as they often require manual data transfer and direct connections, which compromise security.
Innovation Solution
A data transmission device utilizing a memory switch and data checking device to establish secure, indirect connections between data processing systems, ensuring data is transmitted only through a data storage device and checked for malware before transfer, preventing direct access and unauthorized data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a direct data connection is established between insecure and secure data processing systems, then data transfer convenience is improved, but security is worsened due to vulnerability to hacker attacks and malware transmission
Solution Approach 1:
The patent introduces a data transmission device as an intermediary component between insecure and secure data processing systems. This device includes a data storage device and a memory switching device that mediates all data transfers, preventing direct connections while maintaining transfer convenience. The intermediary checks and verifies data before allowing transfer to secure systems, thus resolving the contradiction between ease of operation and security.
2Reliability
If manual data transfer using data carriers is used, then security is improved by avoiding direct connections, but operational complexity is worsened due to manual insertion and verification steps
Solution Approach 1:
The data transmission device automates the data transfer process by implementing self-service functionality. The memory switching device automatically establishes connections between data storage devices and data processing systems without requiring manual intervention. The system autonomously manages data transfer, verification, and connection switching, thereby maintaining high security while reducing operational complexity.
3Object-affected harmful factors
If a copying station with manual verification is used, then malware transmission is prevented, but productivity is worsened due to multiple manual transfer steps
Solution Approach 1:
The patent implements preliminary action by performing data verification and connection establishment before actual data transfer occurs. The memory switching device pre-establishes secure connections and verifies data integrity before allowing transfer to secure systems. This preliminary verification prevents malware transmission while automating the process, thus maintaining security without sacrificing productivity.
4Speed
If direct wired connections are used between data processing systems, then data transfer speed is improved, but security is worsened due to continuous connection vulnerability
Solution Approach 1:
The data transmission device implements periodic action by establishing wired connections only when needed for data transfer, then disconnecting afterward. The memory switching device controls connection timing, creating continuous wired connections only during active transfer operations. This periodic connection approach maintains high transfer speed when needed while minimizing security exposure by disconnecting when not in use.

AI summary
The invention relates to a data transmission device (1) for transmitting data between a first (2) and a second data processing system (3) comprising a memory switching device (5) and a data storage device (7). The memory switching device (5) can establish a connection between the data storage device (7) and the first data processing system and the second data processing system. Depending on its switching state, the memory switching device (5) either establishes a data-transmitting wired connection via at least one electrical or optical conductor (9) between the data storage device (7) and the first data processing system (2) or between the data storage device (7) and the second data processing system (3), or it interrupts any connection between the data processing systems (2, 3) and the data storage device (7).
