Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If acceleration sensor and pressure sensor are used to detect moving state, then measurement capability is improved, but measurement precision for aircraft state is insufficient
Solution Approach 1:
The patent combines data from multiple sensors (acceleration sensor, pressure sensor, and potentially other sensors) to comprehensively determine aircraft moving state. By merging detection results from different sensing mechanisms, the system achieves more reliable aircraft state identification than any single sensor could provide alone, resolving the contradiction between measurement capability and precision.
Solution Approach 2:
The system dynamically adjusts usage restrictions and power management based on real-time detection of aircraft moving state. Rather than static control, the device continuously monitors sensor data and adapts its operation mode (e.g., restricting certain functions during flight, optimizing power consumption), thereby improving both measurement precision application and operational reliability.
2Reliability
If device performs control actions during aircraft mode, then compliance with flight regulations is improved, but power consumption increases
Solution Approach 1:
The system performs preliminary determination of aircraft moving state using sensor data before executing control actions. By pre-identifying the aircraft mode through pattern recognition on sensor readings, the device can proactively switch to compliant operation modes, reducing the need for continuous high-power processing and communication, thereby managing power consumption more efficiently while maintaining regulation compliance.
3Measurement precision
If existing sensing technologies are used, then device complexity is reduced, but measurement precision for aircraft state is insufficient
Solution Approach 1:
The patent makes existing sensors serve multiple functions: the acceleration sensor not only detects general motion but specifically contributes to aircraft state detection when combined with pressure sensor data. The pressure sensor similarly serves both general altitude/pressure monitoring and specific aircraft mode identification. This multi-functional use of existing sensors improves measurement precision without proportionally increasing device complexity.

AI summary
A mobile electronic device (e.g., a mobile phone) includes a sensor and at least one controller. The controller performs a control base on a detection result that is detected by the sensor. For example, the controller is configured to determine a moving state by aircraft base on the detection result that is detected by the sensor. When the sensor is an atmospheric pressure sensor that is configured to detect atmospheric pressure, the controller is configured to determine the moving state by aircraft by a decrease in the atmospheric pressure, and after a determination of the moving state by aircraft, the at least one controller is further configured to keep the determination of the moving state by aircraft until the atmospheric pressure increases.
