Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If network access is allowed freely to mobile units with RFID tags, then ease of operation is improved, but security is worsened
Solution Approach 1:
The patent applies local quality by implementing location-specific network access policies. Different geographic areas (defined by RFID reader zones) have different access rights and security levels. Mobile units are granted network access privileges based on their current physical location, allowing convenient access in authorized areas while automatically restricting access in sensitive or unauthorized zones, thus resolving the contradiction between ease of operation and security.
2Object-affected harmful factors
If RFID-based location control is implemented, then security is improved, but device complexity is worsened
Solution Approach 1:
The patent introduces wireless switches as intermediary devices that automatically mediate between RFID tag location data and network access control. These switches receive location information from RFID readers and autonomously enforce access policies by enabling or disabling network ports, eliminating the need for complex centralized authentication systems while maintaining high security standards.
Solution Approach 2:
The patent replaces traditional manual or software-based access control mechanisms with RFID-based automatic detection and control systems. By using wireless RFID communication and automated wireless switches, the system eliminates complex authentication procedures, manual access granting, and software-based permission management, achieving enhanced security through simpler hardware-based automatic control.
3Adaptability or versatility
If multiple access schemes are implemented for different areas, then adaptability is improved, but device complexity is worsened
Solution Approach 1:
The patent implements dynamic access control where network access privileges are not fixed but automatically adjust based on the mobile unit's real-time location. The wireless switches dynamically enable or disable network ports according to the current area, allowing the system to adapt to different security requirements in different zones without requiring complex configuration or manual intervention, thus achieving high adaptability with simple control logic.

AI summary
A system for controlling access to a network (135) includes a wireless switch (130) configured for radio frequency communication with a mobile unit (110, 112) associated with a radio frequency identification tag (104). The wireless switch is adapted for determining if a radio frequency identification tag is located within a first area (105), and enabling the mobile unit to access the network according to a first scheme if the mobile unit is located within the first area.
