Wireless Server Device Status Update Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, continuously discovering neighboring devices for real-time status recognition leads to high power consumption, particularly in Bluetooth Low Energy and Wi-Fi, making it difficult to balance real-time status detection with power efficiency.
Innovation Solution
A method where a server device registers client devices, updates their status, and transmits status information to a user device, allowing for reduced power consumption by minimizing continuous scanning and enabling real-time status updates through periodic status checks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If continuous scanning is performed to discover neighboring devices in real time, then status detection accuracy is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic scanning intervals instead of continuous scanning. The scanning module performs discovery operations at predetermined time intervals, allowing the device to maintain awareness of neighboring devices while consuming less power during intervals when scanning is suspended.
Solution Approach 2:
The patent introduces a server device as an intermediary that maintains status information about neighboring devices. Instead of each device continuously scanning, the server acts as a central repository that provides status updates to client devices, reducing the scanning burden on individual devices.
2Use of energy by moving object
If scanning interval is extended to reduce power consumption, then power efficiency is improved, but real-time status recognition capability deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the server device monitors status changes of neighboring devices and actively notifies client devices when changes occur. This allows the system to maintain real-time awareness without continuous scanning, as the feedback loop triggers updates only when necessary.
Solution Approach 2:
The server device performs preliminary status monitoring and maintains up-to-date information about neighboring devices in advance. When a client device needs status information, it is already available at the server, eliminating the need for the client to perform energy-intensive scanning operations.
