Mobile Robot Water Distribution System for Uniform Mop Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile robots face challenges in uniformly supplying water to their mops, maintaining consistent friction force, and achieving stable movement, leading to inefficient cleaning and difficulty in navigating corners and walls.
Innovation Solution
The mobile robot features a water distribution system with two symmetrically arranged water distribution pipes of equal length, connected to a single water supply module, ensuring uniform water supply to both mops and improving friction force consistency, while also allowing for detachable components to prevent leaks and facilitate design changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If two water pipes are arranged from the water tank to the body where the mop of each rotating member is disposed, then water can be supplied to both mops, but the length of the water pipes becomes very long causing different accumulation of foreign matter and interference with components, making it difficult to supply the same amount of water uniformly
Solution Approach 1:
The water supply system is segmented into two independent paths: one water pipe supplies water to the first rotating member, and another water pipe supplies water to the second rotating member. Each rotating member has its own water tank attached directly to it, eliminating the need for long water pipes running through the body and preventing foreign matter accumulation and interference issues.
2Device complexity
If two water tanks are attached to each of the first rotating member and the second rotating member, then water supply path is shortened, but rotation of each rotating member occurs and sufficient water quantity cannot be secured
Solution Approach 1:
The water tank is designed to rotate together with the rotating member around the vertical axis, adding rotational freedom in another dimension. This allows the water tank to maintain its position relative to the rotating member while the entire assembly rotates, ensuring continuous water supply to the mop regardless of the rotating member's orientation or rotation angle.
3Ease of operation
If the rotating members are changed to a structure detachable from the body, then ease of operation is improved, but the structure in which each water pipe must be connected to each other is required, changing the amount of water supplied
Solution Approach 1:
The system is segmented into detachable modules: the rotating members with their attached water tanks and mops can be easily detached from and reattached to the body. Each rotating member maintains its own water tank attachment, so detaching and reattaching does not affect water supply consistency or require complex water pipe reconnections.
4Device complexity
If water is supplied uniformly to the mop attached to the rotating member with the water tank located in the body, then water supply is simple, but it is difficult to implement the structure in which water is not leaked and easily detachable
Solution Approach 1:
The water supply system is segmented with each rotating member having its own water tank attached directly to it, rather than using a centralized water tank in the body. This segmentation allows each rotating member to be easily detached and reattached without causing water leakage, as the water supply connection is localized to each rotating member's own water tank rather than requiring connections through the detachable interface with the body.

AI summary
A mobile robot includes a body and a mop module with left and right rotating plates rotatably installed on the body and each including a water supply space. The mobile robot also includes a water distribution module for providing water to the water supply spaces of the left and right rotating plates, and a water supply module for supplying water to the water distribution module. The water distribution module includes a water-supply counterpart portion connected to the water supply module and configured to receive water. Left and right water supply distribution pipes are connected to the water-supply counterpart portion to supply water to the water supply spaces of the left and right rotating plates, wherein the length of the left and right water distribution pipes are the same.
