Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If programmable keys are used for security control, then security reliability is improved, but system scalability deteriorates
Solution Approach 1:
The patent introduces a base station as an intermediary between controllers and security devices. The base station manages security codes and coordinates communication, allowing multiple controllers to work with a limited set of security devices without requiring proportional increases in security device quantity. This mediator architecture enables scalable system expansion while maintaining secure code-based authentication.
Solution Approach 2:
The patent makes security devices controllable by multiple controllers through a shared base station infrastructure. A single security device can respond to commands from any authorized controller that has obtained the appropriate security code, eliminating the need for dedicated one-to-one controller-device pairing and enabling flexible system reconfiguration.
2Device complexity
If peer-to-peer communication is used between controllers and security devices, then system simplicity is improved, but management capability deteriorates
Solution Approach 1:
The patent segments the communication architecture into three distinct layers: base stations for regional management, controllers for operational control, and security devices for protection functions. This hierarchical segmentation allows complex management tasks to be handled at the base station level while keeping individual controller-device interactions simple.
Solution Approach 2:
The base station serves as a mediating management layer that coordinates between multiple controllers and security devices. It handles code distribution, controller authorization, and system-wide security policies, enabling regional management without complicating the basic peer-to-peer communication between controllers and devices.
3Reliability
If security codes are transmitted through infrared or electrical contact, then communication security is improved, but system adaptability deteriorates
Solution Approach 1:
The patent implements a universal communication protocol that works across multiple transmission media including infrared, electrical contact, and wireless communications. The base station and controllers can adapt to different communication methods based on the specific application scenario while maintaining consistent security code transmission and authentication mechanisms.
