Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If motion correlation between mobile terminal and wearable device is implemented for unlocking, then user convenience is improved, but device complexity increases due to additional sensors and communication interfaces
Solution Approach 1:
The patent combines the motion sensing capabilities of the mobile terminal and wearable device through correlation analysis. By merging the sensor data from both devices and comparing motion patterns, the system achieves seamless unlocking without requiring separate authentication mechanisms, thus improving ease of operation while managing device complexity through data integration rather than additional hardware.
Solution Approach 2:
The communication interface acts as an intermediary that enables data exchange between the mobile terminal and wearable device. This mediator facilitates the transfer of motion information and correlation verification, allowing the unlocking function to be implemented without directly increasing the complexity of individual device components, as the intelligence is distributed across the system.
2Measurement precision
If motion sensing is performed during identical time periods for both devices, then synchronization accuracy is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic motion sensing during specific time intervals rather than continuous monitoring. By synchronizing sensing operations to occur during identical time periods when both devices are actively used, the patent achieves accurate motion correlation while minimizing energy consumption by activating sensors only when needed for comparison, rather than maintaining constant monitoring.
Solution Approach 2:
The mobile terminal requests motion information from the wearable device in advance before performing correlation analysis. This preliminary action allows the system to prepare and synchronize data collection timing, ensuring that motion data from both devices corresponds to the same time period for accurate comparison, while enabling energy-efficient batch processing rather than continuous sensing.
3Reliability
If motion correlation threshold is set high for secure unlocking, then security is improved, but ease of operation deteriorates due to false rejections
Solution Approach 1:
The system dynamically adjusts the correlation threshold parameter based on the specific motion patterns being analyzed. By changing the threshold parameter adaptively rather than using a fixed high value, the patent maintains high security for normal operations while allowing temporary lowering of the threshold when motion patterns show high confidence correlation, thus preventing false rejections and improving ease of operation without compromising overall security.

AI summary
A mobile terminal and a method of operating the mobile terminal are provided. The mobile terminal includes a sensor configured to sense a motion of the mobile terminal, and a communication interface configured to receive, from a wearable device corresponding to the mobile terminal, information of a motion of the wearable device, the motion of the wearable device being sensed during a time period from a start time requested by the mobile terminal. The mobile terminal further includes a controller configured to determine whether the motion of the mobile terminal and the motion of the wearable device have a correlation of a level or greater, and unlock the mobile terminal, in response to the controller determining that the motion of the mobile terminal and the motion of the wearable device have the correlation of the level or greater.
