Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile devices lack an automated mechanism to disable wireless radios when on an airplane, relying on manual user intervention to comply with flight regulations, which can lead to inconsistent compliance and potential interference with aircraft systems.
Innovation Solution
An electronic device equipped with classifiers that analyze wireless radio environment data, sensor data, and location metadata to determine if it is on an airplane, automatically disabling wireless radios or prompting the user to enter airplane mode, using a combination of coarse and real-time classifiers and server infrastructure to enhance accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual airplane mode activation is required, then user control is maintained, but compliance consistency deteriorates
Solution Approach 1:
The system automatically detects airplane context and manages radio disabling without requiring user action. The device monitors its own environment (GPS location, barometric pressure, accelerometer data) and autonomously determines when to disable wireless radios, making the system self-regulating rather than relying on manual user intervention.
Solution Approach 2:
The system continuously monitors multiple sensor inputs (GPS coordinates, barometric pressure readings, accelerometer orientation data) and uses this feedback loop to dynamically adjust radio operation. When sensors detect patterns consistent with airplane environment, the system responds by disabling radios, creating a closed-loop control system that adapts to changing conditions.
2Reliability
If automated airplane detection is implemented, then compliance consistency is improved, but device complexity increases
Solution Approach 1:
The detection system is divided into independent modular components: GPS location service, barometric pressure sensor, accelerometer sensor, and classification logic. Each component operates independently and contributes specific data to the overall determination, allowing the system to be built from discrete, manageable units rather than a monolithic complex system.
Solution Approach 2:
The sensor system serves multiple functions: GPS provides location data for navigation and context detection, barometric pressure sensors measure both altitude and cabin pressure changes, accelerometers detect both motion patterns and device orientation. This multi-functionality reduces the need for dedicated components solely for airplane detection, thereby reducing overall complexity.
3Measurement precision
If multiple sensors are used for detection, then detection accuracy is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts sensor sampling rates and activation based on current operational context. Sensors are activated only when needed for airplane detection (e.g., when GPS indicates proximity to airports or during flight phases), and sampling frequencies are adjusted based on whether the device is in airplane mode or normal operation, reducing unnecessary energy consumption while maintaining detection accuracy.

AI summary
Embodiments described herein provide for an electronic device comprising a set of classifiers that can determine whether the electronic device is likely on an airplane. Upon a determination that the electronic device is likely on an airplane, one or more wireless radios on the electronic device (e.g., an ultra-wideband ranging radio, a cellular radio, etc.) may be disabled or a prompt can be displayed to enable a user to place the device into airplane mode.
