Bluetooth Master Device Power-Off Control for Linked Slaves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth devices often require complex controls and additional weight, leading to discomfort and battery waste due to forgotten power-offs, and pose challenges during air travel where multiple devices need to be turned off efficiently.
Innovation Solution
A method and system allowing a linked Bluetooth device to transmit a signal to power-off another device, enabling a single device to initiate a power-off process for all connected devices, either manually or automatically, and to switch to a power-saving mode, simplifying operation and conserving battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Bluetooth devices include individual controls for power management, then functionality is improved, but device complexity and weight increase
Solution Approach 1:
The master device's power button is given universal functionality to control not only itself but also all slave devices in the Bluetooth network. This eliminates the need for individual power buttons on each slave device, reducing overall device complexity while maintaining full power management functionality across the network.
2Ease of operation
If timing circuits are used to automatically power off devices, then ease of operation is improved, but energy is still wasted when devices remain powered on
Solution Approach 1:
The master device continuously monitors the operational state of slave devices and receives feedback about their usage status. Based on this feedback, the master device can send commands to power off slave devices that are no longer in use, ensuring complete power conservation while maintaining ease of operation through automatic control.
3Reliability
If multiple devices need to be powered off during air travel, then safety requirements are met, but time and risk of damage increase
Solution Approach 1:
The system maintains ready-state connectivity between master and slave devices, pre-establishing the communication channel needed for rapid power-off commands. When air travel mode needs to be activated, the master device can immediately send power-off commands to all slave devices without requiring manual intervention or establishing connections first, thus meeting safety requirements quickly and reducing the risk of device damage from being dropped.

AI summary
Methods and systems for powering-off a wireless communication device from a linked device are provided. A device can transmit a wireless communication signal to a linked device to instruct the linked device to power-off. In this manner, the user need only turn off one device manually which results in all linked devices being powered off. This process can be initiated by a user through a device directly linked with the device to be powered-off or through a device that is indirectly connected, through one or more wireless communication networks, with the device to be powered-off. This process can also be automatically initiated by a device when a set of predetermined conditions exist. Once instructed to do so, a device can initiate a predetermined power-off process which can involve terminating any ongoing functions and turning off various subsystems. In accordance with the present invention, a user can initiate a power-off of all the devices on a wireless communication network through a single device.
