Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot cleaners that use rotating mops for cleaning face issues with stability, straight-line travel, varying frictional force, limited speed and route options, difficulty in performing mopping without rotation, and inefficient moisture removal.
Innovation Solution
A cleaner design incorporating a first cleaning module with left and right spin mops, a second cleaning module with a rolling member, and a water supply module, allowing for stable operation without a separate driving wheel, enabling various travel speeds and routes, and effective wet and dry mopping with sterilization capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a robot cleaner uses a pair of left and right mops in a two-point support manner, then the device can move and perform cleaning, but stability in the forward-and-backward direction is deteriorated
Solution Approach 1:
The cleaner is divided into multiple support points: a first cleaning module with left and right mops, a second cleaning module with a rolling member, and a body. This segmentation from two-point to multi-point support resolves the stability issue while maintaining mobility
Solution Approach 2:
The support structure is extended from a single plane to multiple dimensions by adding the rolling member as a separate support element, creating a more distributed support system that improves stability in the forward-and-backward direction
2Speed
If the robot cleaner moves via rotation of a pair of left and right mops, then the device can travel, but the frictional force varies frequently making it difficult to travel straight
Solution Approach 1:
The rolling member acts as an intermediary element that provides more stable frictional force compared to the rotating mops. It mediates the motion between the rotating mops and the floor, enabling straighter travel by supplementing the variable frictional force with more consistent contact
3Adaptability or versatility
If the robot cleaner uses rotation of mops for movement, then the device can travel, but limitations are imposed on traveling speed and traveling route
Solution Approach 1:
The cleaning system is designed with multiple modules (first cleaning module with spin mops, second cleaning module with rolling member) that can work in different combinations. This multi-functionality allows the device to achieve various traveling speeds and routes by selectively engaging different modules for different operational requirements
4Ease of operation
If the robot cleaner moves via rotation of mops, then the device can travel, but it is difficult to perform mopping operation without rotating in place or moving linearly
Solution Approach 1:
The cleaning function is segmented into two independent modules: the first cleaning module with rotating spin mops for mopping operations, and the second cleaning module with a rolling member for movement. This segmentation allows the mopping module to operate independently without requiring the entire device to rotate or move linearly, enabling mopping while staying in place

Implementation Method 1
a first cleaning module including a left spin mop and a right spin mop provided so as to come into contact with a floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from the upper side
Implementation Method 2
a second cleaning module configured so as to come into contact with the floor at a position spaced apart from the left spin mop and the right spin mop in a forward-and-backward direction

AI summary
A cleaner includes a first cleaning module including a left spin mop and a right spin mop that come into contact with a floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from an upper side, a second cleaning module that comes into contact with the floor at a position spaced apart from the left spin mop and the right spin mop in a forward-and-backward direction, a body supported by the first cleaning module and the second cleaning module, and a water supply module that supplies water to the first cleaning module. A water tank is disposed inside the body. Water supplied by the water supply module reaches the first cleaning module before reaching the floor.
