Dynamic Master Device Selection for Smart Home Network Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device networking systems in smart home environments are prone to network instability and downtime when the master device experiences exceptions such as disconnection, faults, or power failures, leading to poor user experience.
Innovation Solution
A device networking method where a first device determines a second device of a specific type (powered by an external power supply) as the master device, and upon occurrence of an exception, dynamically adjusts the master device to a third device of another type (powered by a battery) based on parameters like electric quantity, wakeup duration, and frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a device powered by a battery is selected as the master device, then the device can operate portably, but the network duration is limited by battery power
Solution Approach 1:
The patent applies universality by enabling both battery-powered devices and externally-powered devices to function as master devices in the network. The system dynamically selects the appropriate master device type based on operational needs, allowing the network to leverage both portability (from battery devices) and extended duration (from externally-powered devices) across different operational scenarios.
2Duration of action of moving object
If a device powered by an external power supply is selected as the master device, then the network duration can be extended, but the portability and flexibility are reduced
Solution Approach 1:
The patent implements dynamics by making the master device selection flexible and adaptive rather than fixed. The system can dynamically switch between battery-powered master devices (for portability) and externally-powered master devices (for extended duration) based on real-time operational requirements, resolving the contradiction between portability and network duration.
3Productivity
If a master device is used to manage and control slave devices, then the network can operate efficiently, but the network stability deteriorates when the master device experiences exceptions
Solution Approach 1:
The patent applies local quality by introducing a standby master device with specific qualities (pre-configured, ready-to-takeover) to complement the active master device. This local enhancement at the master device level ensures that network efficiency is maintained while simultaneously improving network stability through the availability of a backup controller.
Solution Approach 2:
The patent implements beforehand cushioning by pre-configuring a standby master device that is ready to take over control if the active master device fails. This preparatory measure cushions against potential master device failures, maintaining network stability without compromising current operational efficiency.
4Reliability
If the master device is frequently switched to maintain network stability, then the network can remain operational, but the network stability itself deteriorates due to switching overhead
Solution Approach 1:
The patent applies preliminary action by pre-configuring the standby master device with all necessary control parameters and slave device information before any failure occurs. This preliminary preparation enables seamless takeover without requiring frequent or disruptive switching operations, thus maintaining both network stability and compositional integrity.
