Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless network is used for data transmission in conference, then data transmission convenience is improved, but network stability and security deteriorate
Solution Approach 1:
The patent introduces NFC and Bluetooth as intermediary technologies to enable direct device-to-device communication without relying on wireless networks. The NFC trigger initiates the connection, and Bluetooth serves as the primary data transmission channel, both acting as mediators between the conference terminal and mobile terminals to eliminate network dependency while maintaining convenience and security.
Solution Approach 2:
The patent replaces the network-based data transmission system with a direct peer-to-peer communication system using NFC and Bluetooth technologies. This substitution eliminates the intermediary wireless network infrastructure, allowing terminals to communicate directly through dedicated communication modules, thereby improving both reliability by removing network vulnerabilities and maintaining ease of operation through automated connection processes.
2Reliability
If USB flash disk is used for data transmission in network-free environment, then data transmission security is improved, but operation complexity increases
Solution Approach 1:
The patent implements automated connection and authentication mechanisms where the conference terminal automatically reads NFC triggers from mobile terminals, establishes Bluetooth connections, and performs authority level verification without manual intervention. This self-service approach maintains the security of direct device communication while eliminating the operational complexity of manual USB flash disk handling, as users simply need to bring their devices close for automatic connection.
Solution Approach 2:
The patent performs preliminary actions by pre-configuring authority levels and file access permissions in the system. Before actual data transmission occurs, the terminal reads the NFC trigger, verifies the mobile terminal's authority level, and pre-establishes the Bluetooth connection. This preliminary authentication and connection setup simplifies the user experience while maintaining security, as the complex verification processes occur automatically before the user needs to access any files.
3Reliability
If authority level control is implemented, then data access security is improved, but system complexity increases
Solution Approach 1:
The patent applies local quality by assigning different authority levels to different mobile terminals based on their specific roles and permissions. Each terminal receives customized file access rights corresponding to its authority level, allowing the system to implement fine-grained security control without requiring complex centralized management. The conference terminal locally determines which files to transmit based on the mobile terminal's authority level, simplifying the overall system architecture while maintaining robust security.
