Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile terminal is used for user authentication, then convenience is improved, but authentication time increases
Solution Approach 1:
The system performs preliminary actions by detecting the user's approach in advance and pre-establishing communication channels. The detection sensor identifies when a mobile terminal enters the authentication area, triggering pre-configured authentication sequences and pre-loading necessary verification data, thereby reducing actual authentication time while maintaining convenience.
2Adaptability or versatility
If conventional BLE communication is used, then device compatibility is improved, but communication time varies and increases
Solution Approach 1:
The system dynamically adjusts communication parameters based on real-time conditions. It monitors signal strength, device type, and authentication stage to automatically optimize BLE communication settings such as transmission power, packet size, and connection interval. This dynamic adaptation reduces communication time variability while maintaining broad device compatibility.
Solution Approach 2:
The system changes communication parameters adaptively during the authentication process. It modifies transmission power levels, data packet structures, and communication protocols based on the detected terminal type and authentication progress. These parameter adjustments optimize communication efficiency for different devices while reducing overall authentication time.
3Adaptability or versatility
If mobile terminal acquires authentication information, then functionality is improved, but processing time increases
Solution Approach 1:
The authentication information acquisition process is segmented into multiple parallel tasks. The system divides information gathering, verification, and processing into separate modular operations that can execute concurrently. Different authentication data types (biometric, credential-based, contextual) are processed through dedicated sub-routines, improving overall processing speed while maintaining comprehensive functionality.

AI summary
Disclosed is a control method of a control device, the control method including determining whether a movable object is located in a first area using a detection sensor, activating a first mode among operation modes of the control device when it is determined that the movable object is located in the first area, acquiring user confirmation information from a terminal when the first mode is activated wherein the user confirmation information corresponds to user-specific information stored in the terminal and is provided to the terminal by a server before the terminal provides the user confirmation information to the control device, transmitting processing request information based on the user confirmation information to the server so that the server performs processing on the user confirmation information, acquiring a processing result for the user confirmation information from the server, and providing the processing result for the user confirmation information to the terminal.
