Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional PIN or password entry methods are used for unlocking, then security authentication is provided, but the entered PIN or password may be visible to others and the unlocking procedure becomes tedious and time-consuming
Solution Approach 1:
The patent combines fingerprint sensor detection with motion sensor detection to create a unified authentication system. The fingerprint sensor verifies the user's identity while the motion sensor captures the device's movement pattern, and both are processed together by the microcontroller to determine authentication success, eliminating the need for separate PIN entry
Solution Approach 2:
The patent replaces the mechanical/manual system of typing PIN or password with a biometric and motion-based system. The fingerprint sensor captures ridges and valleys patterns, while motion sensors detect acceleration and orientation changes, substituting the manual keyboard entry process with automatic sensor-based authentication
2Reliability
If password or unlocking pattern complexity is increased to comply with security requirements, then security is improved, but the entire unlocking procedure becomes more tedious and time-consuming
Solution Approach 1:
The system performs preliminary authentication by detecting the device's motion pattern and orientation before requiring fingerprint verification. The microcontroller continuously monitors motion sensor data and compares it against stored motion patterns, initiating the authentication process in advance of actual user interaction with the device
3Adaptability or versatility
If the device stores many applications, then functionality and versatility are improved, but searching for a specific application by navigating from the desktop or multiple screen pages becomes cumbersome
Solution Approach 1:
The system enables direct application launch through motion-based commands without requiring manual navigation. Users can perform specific motions (such as circular movements or directional gestures) that automatically trigger corresponding applications, allowing the system to serve itself by interpreting motion patterns as application launch commands

AI summary
The disclosure provides a method, mobile electronic device, and computer readable medium for operating the mobile electronic device having a motion sensor, touch sensor, microcontroller, and processor. The method includes the following steps. The motion sensor detects a motion and generates motion data in response to the detected motion. The touch sensor detects a fingerprint and generates fingerprint data in response to the detected fingerprint. The microcontroller compares the generated motion data with enrolled motion data, and one of the microcontroller and the processor compares the generated fingerprint data with enrolled fingerprint data, where the enrolled fingerprint data and the enrolled motion data including the first motion data are prestored in the mobile electronic device. When the generated motion data matches the first motion data and the generated fingerprint data matches the enrolled fingerprint data, the processor performs a first action in associated with the first motion data.
