Solution Overview

Problem

Existing methods for controlling device connections can lead to unintended unlocking, compromising device security and user experience due to inconsistent screen states and changes in connection modes.

Innovation Solution

A method and apparatus for controlling devices that determine changes in connection states and maintain consistent screen states by executing operations to exit or enter an unlocked state based on specific connection conditions, such as removing or adding device information to trusted lists or disconnecting connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If one electronic device is used to unlock another device through connection, then device accessibility and convenience are improved, but unintended unlocking occurs reducing device security

Engineering Contradiction:
Improvedevice accessibilityVSAvoiddevice security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system continuously monitors connection state changes between devices and provides feedback to adjust screen state accordingly. When connection state changes are detected, the system automatically adjusts whether the screen remains unlocked or locks, preventing unintended unlocking while maintaining secure access when appropriate

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The screen state is made dynamic rather than static, automatically adjusting based on real-time connection state changes. The system transitions between unlocked and locked states according to whether devices are connected or disconnected, ensuring security is adapted to current usage conditions

Inventive Principle:
Principle #15Dynamics

2Device complexity

If connection state changes are not monitored, then device complexity is reduced, but screen state inconsistency occurs compromising security

Engineering Contradiction:
Improvecontrol mechanism simplicityVSAvoidscreen state consistency
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system automatically monitors and responds to connection state changes without requiring user intervention. The screen state adjustment occurs autonomously based on detected connection changes, maintaining consistency while avoiding complex user-controlled mechanisms

Inventive Principle:
Principle #25Self-service

AI summary

This application provides a method for controlling devices, a device control apparatus, and a computer readable storage medium. The method for controlling devices includes determining that a state of a connection between a first device and a second device has changed; determining that the first device is in a target state, wherein in the target state, the first device is connected to the second device through a first connection, and based on the first connection, the first device maintains an unlocked screen state; and performing a first operation, the first operation being used to make the first device exit the target state.
