Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If intelligent terminals are customized and developed for specific use requirements, then specific use requirements are met, but the cost of customizing and developing increases
Solution Approach 1:
The patent segments the terminal device into a general-purpose terminal and a separate data white box device. The data white box device contains the SIM unit and memory, which are customized components. This segmentation allows the general-purpose terminal to remain standardized while specific requirements are met through the configurable data white box device, thereby reducing customization costs.
Solution Approach 2:
The data white box device is designed as a universal solution that can be applied to multiple general-purpose terminals. The SIM unit and memory configuration can be adapted to meet different specific use requirements while using the same underlying hardware platform, achieving versatility without proportionally increasing manufacturing complexity.
2Reliability
If hardware related to security authentication is added to the intelligent terminal, then security requirements are met, but the device complexity and cost increase
Solution Approach 1:
The patent extracts the security authentication hardware (SIM unit) from the general-purpose terminal and places it in a separate data white box device. This extraction allows the terminal to meet security requirements without incorporating complex security hardware directly into the terminal design, thereby reducing device complexity while maintaining security functionality.
Solution Approach 2:
The data white box device acts as an intermediary between the general-purpose terminal and the security authentication system. The SIM unit within the white box device handles security authentication requests from the terminal, providing security functionality without requiring the terminal itself to contain complex security hardware.
3Reliability
If different intelligent terminals are selected for different security scenarios, then security requirements are met, but the device complexity and user burden increase
Solution Approach 1:
The patent creates a universal data white box device that can serve multiple application scenarios with different security requirements. By configuring the SIM unit and memory within the white box device, the same hardware platform can adapt to various security scenarios without requiring different terminal models, thereby maintaining versatility while meeting diverse security needs.
