Solution Overview

Problem

In double washing stations that integrate laundry treating equipment and a cleaning robot, the drum of the laundry treating equipment can collide with the cleaning robot due to vibration during spinning, leading to abnormal sounds and potential damage to the cleaning robot.

Innovation Solution

A cleaning equipment control method that detects whether the drum satisfies a touch condition with the cleaning robot, and if so, controls the cleaning robot to move out from its position below the drum to avoid collisions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the cleaning robot is integrated below the laundry treating equipment to reduce space, then the space occupied by the cleaning equipment is reduced, but the drum may collide with the cleaning robot during spinning operation causing abnormal sounds and potential damage

Engineering Contradiction:
Improvespace occupied by cleaning equipmentVSAvoidrisk of collision damage to cleaning robot
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The control system detects whether the cleaning robot is in the charging area and whether the drum rotation may cause collision before the spinning operation starts. If a collision risk is detected, the control system preemptively sends a control instruction to move the cleaning robot away from the charging area, preventing the collision from occurring in the first place

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors the position of the cleaning robot and the state of the drum rotation through detection units. Based on the feedback information about robot position and drum state, the control system dynamically adjusts the operation by sending movement instructions to the robot when collision risk is detected, creating a closed-loop control system that prevents collision

Inventive Principle:
Principle #23Feedback

2Productivity

If the drum rotates at high speed during spinning, then the laundry treating efficiency is improved, but the drum may vibrate and collide with the cleaning robot

Engineering Contradiction:
Improvelaundry treating efficiencyVSAvoiddrum vibration and collision
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The control system acts as an intermediary between the drum rotation and the cleaning robot. It monitors the drum rotation state and robot position, and when high-speed spinning is detected combined with robot presence in the charging area, the control system intervenes by sending movement instructions to the robot, mediating the potential harmful interaction between drum vibration and robot

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the cleaning robot remains in the charging area during laundry treatment, then the cleaning robot is ready for immediate operation, but the robot may be damaged by drum collision

Engineering Contradiction:
Improvereadiness of cleaning robotVSAvoiddamage risk to cleaning robot
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The position of the cleaning robot is made dynamic rather than static. The robot can automatically adjust its position based on real-time detection of drum rotation state and its own location in the charging area. When high-speed spinning is detected, the robot dynamically moves away from the charging area to avoid collision, then can return afterward to maintain readiness

Inventive Principle:
Principle #15Dynamics

AI summary

The disclosure provides a cleaning equipment control method and an electronic device, and a storage medium, and relates to the technical field of cleaning equipment. The cleaning equipment includes laundry treating equipment (110) and a cleaning robot (120) arranged below a drum (111) of the laundry treating equipment (110), where the cleaning robot (120) can be moved out from a position below the drum (111). The method includes: detecting whether the drum (111) satisfies a touch condition in the case that the cleaning robot (120) is located below the drum; and controlling the cleaning robot (120) to move out from the position below the drum (111) if the drum (111) satisfies the touch condition.
