Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If devices are allowed to connect freely to the network, then communication efficiency is improved, but security risk increases due to unauthorized access and malware propagation
Solution Approach 1:
The patent introduces a security apparatus as an intermediary device between the network and connected devices. This security apparatus authenticates connection commands and controls communication ranges, allowing legitimate devices to communicate efficiently while blocking unauthorized access and malware propagation attempts.
Solution Approach 2:
The patent implements dynamic communication range control where the security apparatus adjusts which devices can communicate based on authentication results. The communication range is not fixed but changes dynamically according to the connection command and authentication outcome, enabling efficient communication for authorized devices while maintaining security.
2Productivity
If authentication and path control are integrated in one apparatus, then security management efficiency is improved, but device complexity increases
Solution Approach 1:
The patent combines authentication functionality and communication path control functionality into a single security apparatus. This integration improves security management efficiency by handling both functions in one device, and the patent addresses the complexity issue through unified design where the authentication unit and switching unit work together as an integrated system.
Solution Approach 2:
The security apparatus performs multiple functions including authentication of connection commands, control of communication ranges, and prevention of unauthorized access. By making the apparatus universal and multi-functional, the patent reduces the need for multiple separate devices while managing complexity through integrated design.
3Reliability
If communication range is restricted based on authentication, then security is improved, but communication flexibility deteriorates
Solution Approach 1:
The patent implements dynamic communication range control where the security apparatus adjusts which devices can communicate based on authentication results. The communication range is not fixed but changes dynamically according to the connection command and authentication outcome, enabling efficient communication for authorized devices while maintaining security.
