Solution Overview

Problem

Self-mobile devices, such as self-propelled sweeping, mopping, and window-cleaning devices, lose power when not on a charging pile and enter a sleep state, making it impossible for them to upload their position when powered off, thus becoming difficult to locate.

Innovation Solution

The method involves recording a target sleep duration and comparing it with a preset sleep duration to send positioning information to a storage address, ensuring timely upload before power-off, allowing the user to retrieve the device's position through an application terminal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the self-mobile device enters sleep state to save power, then power consumption is reduced, but the device cannot upload positioning information and becomes difficult to locate

Engineering Contradiction:
Improvepower consumptionVSAvoidpositioning information
Core Design Contradiction:
Use of energy by moving objectVSLoss of information

Solution Approach 1:

The device performs preliminary action by uploading positioning information before entering the sleep state. The controller determines that the device has been away from the charging pile for a predetermined time, then uploads the positioning information to the server in advance, ensuring the user can still locate the device even after it enters sleep mode and cannot communicate further.

Inventive Principle:
Principle #10Preliminary action

2Loss of information

If the device remains awake to upload position information, then positioning information is available, but power consumption increases

Engineering Contradiction:
Improvepositioning informationVSAvoidpower consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The positioning information is uploaded in advance before the device enters sleep state, rather than keeping the device awake continuously. This preliminary action ensures positioning information is available while minimizing power consumption by allowing the device to enter low-power mode afterward.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The device autonomously determines when it has been away from the charging pile for the predetermined time and automatically uploads its positioning information without requiring user intervention or continuous monitoring, thereby saving power while ensuring information availability.

Inventive Principle:
Principle #25Self-service

3Use of energy by moving object

If the device is powered off after sleep state, then power is saved maximally, but the user cannot find the device

Engineering Contradiction:
Improvepower consumptionVSAvoiddevice location
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The positioning information is uploaded before the device enters sleep state and before it is powered off. This preliminary action ensures that even though the device will be powered off to maximize power savings, the user can still locate the device through the application terminal using the previously uploaded positioning information.

Inventive Principle:
Principle #10Preliminary action

AI summary

The present application relates to the technical field of device control, and discloses a device position determination method and apparatus, a self-moving device, and a readable storage medium. The method comprises : recording a target sleep duration, and comparing the target sleep duration with a preset sleep duration, wherein the target sleep duration is used for indicating a duration in which a self-moving device is continuously in a sleep state; and when it is determined by means of the comparison that the target sleep duration is equal to the preset sleep duration, sending positioning information to a storage address, so that a user can learn about the actual position of the device on the basis of the positioning information.
