Floor Mopping Robot Water Spray Control Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor mopping robots face inefficiencies in water spray control, leading to insufficient cleaning at the beginning of the task and insufficient water for completing all cleaning tasks due to the steady water spray method.
Innovation Solution
A water spray control method and apparatus for a floor mopping robot that adjusts the water spray amount based on pre-set thresholds related to the out-of-station distance, cleaned area, and moved distance, switching between a first pre-set amount and a second pre-set amount that is less than the first.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a steady water spray amount is maintained throughout the cleaning task, then the water spray system is simple to control, but the cleaning effect is insufficient at the beginning and water runs out before completing all cleaning tasks
Solution Approach 1:
The cleaning task is divided into multiple stages based on the robot's movement distance from the charging station. The first stage (when distance is less than a first threshold) uses a first water spray amount, while the second stage (when distance is greater than or equal to the first threshold) uses a second water spray amount. This segmentation allows the system to provide sufficient water for effective cleaning without requiring complex real-time adjustments throughout the entire cleaning process.
Solution Approach 2:
The system pre-sets different water spray amounts for different stages of the cleaning task based on the robot's movement distance. By determining the appropriate water spray amount in advance for each stage rather than adjusting it dynamically during operation, the system ensures sufficient cleaning effect while maintaining simple control logic.
2Productivity
If a larger water spray amount is used throughout the cleaning task, then the cleaning effect is improved, but the water consumption increases and operational time is reduced
Solution Approach 1:
The cleaning task is divided into stages based on movement distance, with the first stage using a first water spray amount and the second stage using a second water spray amount. This segmentation ensures that water is sprayed at appropriate amounts for each stage, improving cleaning effect while avoiding excessive water consumption that would reduce operational time.
Solution Approach 2:
The water spray amount parameter is changed based on the robot's movement distance from the charging station. By adjusting the water spray amount parameter according to the stage of the cleaning task, the system achieves effective cleaning while optimizing water consumption to extend operational time.
3Loss of substance
If a smaller water spray amount is used throughout the cleaning task, then water consumption is reduced and operational time is extended, but the cleaning effect becomes insufficient
Solution Approach 1:
The cleaning task is segmented into stages based on movement distance, with different water spray amounts applied to each stage. This ensures that sufficient water is provided when needed (in the first stage) while reducing water consumption in later stages, thereby extending operational time without compromising cleaning effect.
Solution Approach 2:
The water spray amount parameter is dynamically adjusted based on the robot's movement distance from the charging station. This parameter change ensures that the cleaning effect remains sufficient while optimizing water consumption to extend operational time.

AI summary
The present disclosure provides a floor mopping robot and its water spray control method and apparatus and a readable storage medium, the water spray control method includes: a first control step, configured to control, in a first stage, a water spray system of the floor mopping robot to spray a first pre-set amount of water; and a second control unit, configured to control, in a second stage after the first stage, the water spray system to spray a second pre-set amount of water each time, where, each of the first stage and the second stage is related to an out-of-station distance, an already cleaned area, or an already moved distance of the floor mopping robot, where the out-of-station distance is a distance that the floor mopping robot has moved away from a charging station since start-up, where the second pre-set amount of water is less than the first pre-set amount of water. As such, while the cleaning effect of the floor mopping robot is enhanced, the service time of the floor mopping robot is also increased without increasing the volume of the water tank.
