Robot Cleaner Water Supply Control for Battery-Matched Mopping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robot cleaners face performance and efficiency issues due to uncontrolled water supply, leading to inconsistent cleaning modes (wet or dry mopping) based on battery state, which can result in incomplete cleaning tasks.
Innovation Solution
A robot cleaner with a controller that manages the water supply to the mops based on the battery state, ensuring the water is depleted within a predetermined time frame matching the expected cleaning duration, adjusting the liquid supply amount per unit time, and controlling the water pump operation to maintain optimal mop moisture for efficient cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the robot cleaner supplies water to the mop without considering battery state, then the mop can be kept damp for cleaning, but the water may be exhausted before the cleaning task is complete, resulting in inconsistent cleaning modes
Solution Approach 1:
The controller pre-calculates the expected water consumption based on battery capacity and cleaning duration before the cleaning task starts. It determines the appropriate water supply rate in advance to ensure water is depleted exactly when the cleaning task completes, preventing mode inconsistency during operation
Solution Approach 2:
The controller continuously monitors battery state and adjusts water supply rate dynamically during cleaning. By using real-time battery level feedback, the system optimizes water consumption to match actual cleaning duration, ensuring consistent wet mopping mode throughout the task
2Duration of action of stationary object
If the robot cleaner increases water supply rate, then the mop remains damp longer, but the water tank is depleted faster, reducing overall cleaning duration
Solution Approach 1:
The controller dynamically adjusts the water supply rate parameter based on battery state and cleaning progress. By optimizing this parameter, the system achieves the right balance between maintaining mop dampness and completing the full cleaning duration without water depletion
3Quantity of substance
If the robot cleaner decreases water supply rate, then the water tank lasts longer, but the mop dries out faster, reducing cleaning effectiveness
Solution Approach 1:
The water supply rate is made dynamic rather than fixed. The controller adjusts the supply rate in real-time based on battery level and cleaning progress, ensuring the mop receives adequate moisture to maintain cleaning effectiveness throughout the entire cleaning task

Function Achieved in This Case
The solution ensures consistent and efficient cleaning by maintaining the mop in a dampened state for extended periods, matching the battery's expected use time, thereby preventing incomplete cleaning tasks and optimizing cleaning performance.
Implementation Method 1
a pump configured to deliver the liquid from the tank to the mop
Implementation Method 2
a mop configured to contact the floor and wipe the floor... the controller manages the delivery of the liquid from the tank to the mop

AI summary
A robot cleaner and a method of controlling the robot cleaner are disclosed. The robot cleaner may include a body, a mop, an actuator, a battery, a tank, and a controller. The controller controls a supply of liquid from the water tank to the mop, and the supply of the liquid may be controlled in consideration of a state of the battery. Water injection may be controlled according to an expected use time of the battery, such that the mop can maintain an appropriate water content, and uniform mopping and cleaning can be performed.
