Mobile Terminal Locking via Acceleration Sensor Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminal locking and unlocking mechanisms unnecessarily lock devices when stationary, reducing usability and user experience by requiring manual unlocking after a period of inactivity, despite low risk of misoperations in static states.
Innovation Solution
Employing an acceleration sensor to detect the location state of a mobile terminal, starting a stabilization timer, and resetting it when the state becomes unstable, allowing the device to automatically switch to a stable and unlocked state when stable for a set period, independent of user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal locks automatically after a set time of no operation, then misoperation prevention is improved, but usability deteriorates due to unnecessary locking in static states
Solution Approach 1:
The patent changes the locking criterion from time-based (no operation for set time) to state-based (location state changes). By using acceleration sensor data to detect whether the terminal is in motion or stationary, the system adapts the locking behavior to the actual usage state, preventing unnecessary locks when the terminal is statically placed and maintaining security when the terminal is being actively used or moved.
2Reliability
If the terminal requires manual unlocking after locking, then security is improved, but operation complexity increases due to additional unlocking procedures
Solution Approach 1:
The patent implements self-service unlocking by automatically determining the terminal state through acceleration sensor detection. When the terminal is detected to be in a stable, stationary state, the system automatically unlocks without requiring user intervention. This eliminates the need for manual unlocking operations while maintaining appropriate security levels, as the system intelligently distinguishes between intentional placement (no unlock needed) and actual usage scenarios.
3Reliability
If the terminal locks in stable states, then misoperation prevention is improved, but time efficiency deteriorates due to unnecessary locking during normal use
Solution Approach 1:
The patent inverts the conventional locking logic by locking when the terminal is in motion or being moved rather than when it is stationary. Instead of assuming no operation means the user has finished using the device, the system detects location state changes and locks only when movement is detected, indicating the device is being transported. This inversion prevents unnecessary locking during normal stationary use while maintaining security during transport.

AI summary
A method, a device, and a mobile terminal for controlling locking and unlocking are provided. The method includes the following steps. An acceleration sensor is adopted to detect a location state of a mobile terminal. A stabilization timer is started and a stabilization timing value of the stabilization timer is monitored when the mobile terminal is in an unlocked or a locked state. The stabilization timing value is reset to restart timing when it is monitored that the location state of the mobile terminal is unstable. The mobile terminal is controlled to enter a stable and unlocked state when it is monitored that the stabilization timing value reaches a stabilization timing threshold. Through the technical solutions, it is determined whether the mobile terminal enters the stable and unlocked state according to the location state of the mobile terminal in the locked or unlocked state. In this manner, the mobile terminal may not be locked in the stable state, and the afterward operations may be facilitated, thereby increasing usability of the mobile terminal and improving user's experience.
