Electronic Device Master-Slave Role Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device technologies that establish a master-slave relationship between devices are inconvenient due to restrictions in use modes, necessitating an improvement in user convenience for such devices.
Innovation Solution
An electronic device equipped with a first communication module for establishing a master-slave relationship and a controller that determines the carrying state and adjusts the control accordingly, allowing automatic switching of the master-slave roles based on user interaction and device positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a master-slave relationship is established between electronic devices, then communication control is improved, but user convenience deteriorates due to restrictions in use modes
Solution Approach 1:
The patent applies dynamics by making the master-slave relationship changeable rather than fixed. The electronic device can dynamically switch between master and slave roles based on detected carrying states (whether the device is being carried or not). This dynamic adaptation resolves the contradiction by maintaining reliable communication control through structured master-slave relationships while improving user convenience by automatically adjusting roles based on usage context, eliminating manual intervention requirements.
2Measurement precision
If manual intervention is required to change master-slave relationship, then control precision is improved, but productivity deteriorates due to additional操作步骤
Solution Approach 1:
The patent applies self-service by enabling the electronic device to automatically determine its own carrying state and autonomously switch between master and slave roles without requiring manual user intervention. The device monitors its own state (carried or not carried) and independently makes control decisions, thereby maintaining precise control over the master-slave relationship while significantly improving operational efficiency by eliminating manual steps for role switching.

AI summary
A mobile phone includes a communication module for establishing a master-slave relationship with another electronic device to perform communication. The mobile phone determines a carrying state and performs control related to the master-slave relationship of the communication module based on a determination result of the carrying state. By this configuration, the mobile phone can improve user's convenience with respect to the use modes of electronic devices between which the master-slave relationship is established. For example, when it is determined that the carrying state is a carried state, the mobile phone may make the communication module subordinate to the other electronic device.
