Advertisement Packet Switching for Electronic Loss Reporting

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Electronic devices face challenges in determining their loss state when not consistently connected to an external device, leading to increased power consumption and server overload due to frequent broadcasting of identification information.

Innovation Solution

The electronic device transmits an advertisement packet in a first attribute to check for a scan request, and if none is received, it switches to a second attribute with loss notification information, reducing unnecessary transmissions and conserving power.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the electronic device frequently broadcasts identification information to determine loss state, then the reliability of loss detection is improved, but power consumption increases

Engineering Contradiction:

Improveloss detection reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The electronic device performs periodic advertisement packet transmissions at predetermined intervals to check for scan requests from paired devices. This periodic action allows the device to determine loss state reliably over time without continuous broadcasting, thereby reducing power consumption while maintaining detection reliability.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The electronic device autonomously determines its own loss state by monitoring whether scan requests are received from paired devices. The device self-manages the loss detection process by comparing received scan requests against stored paired device information, eliminating the need for external intervention and reducing unnecessary communications.

Inventive Principle:

Principle #25Self-service

2Reliability

If the electronic device frequently broadcasts identification information, then the loss state can be determined, but server overload occurs due to frequent reception of unnecessary information

Engineering Contradiction:

Improveloss state determinationVSAvoidserver processing capacity

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The electronic device performs preliminary checks by transmitting advertisement packets and monitoring for scan requests from paired devices before determining loss state. This preliminary action filters out cases where the device is merely temporarily disconnected, reducing unnecessary loss notifications to the server and preventing server overload.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The electronic device uses feedback from received scan requests to dynamically adjust its loss detection behavior. When scan requests are received from paired devices, the device continues normal operation; when no scan requests are received over multiple intervals, the device determines loss state and notifies the server, optimizing server communication based on actual loss conditions.

Inventive Principle:

Principle #23Feedback

AI summary

An electronic device includes a communication circuit, a memory, and a processor operatively connected to the communication circuit and the memory. The processor can be configured to: transmit, through the communication circuit, an advertisement packet having a first attribute; check, on the basis of identification information stored in the memory, whether a scan request packet is received from an external electronic device corresponding to the identification information; and transmit, through the communication circuit, an advertisement packet having a second attribute including loss notification information, if the scan request packet is not received from the external electronic device.
