Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot cleaners face issues with stability, particularly in the forward-and-backward direction, due to variable frictional force generated by rotating mops, leading to difficulties in traveling straight, limited speed, and restricted routes, as well as challenges in performing mopping operations without rotating or moving linearly.
Innovation Solution
A cleaner design incorporating a first cleaning module with left and right spin mops and a second cleaning module with a rolling member, supported by a body that can move via rotation without a separate driving wheel, enhancing stability and allowing for various traveling speeds and routes, while also enabling wet and dry mopping operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a robot cleaner is supported by a pair of left and right mops in a two-point support manner, then the structure is simple, but stability in the forward-and-backward direction is deteriorated
Solution Approach 1:
The support system is segmented into three independent contact points: left mop, right mop, and rolling member. This segmentation allows each component to contribute differently to stability, with the rolling member providing a stable third point that prevents forward-backward tilting while maintaining structural simplicity
Solution Approach 2:
The rolling member acts as an intermediary element between the body and the floor, providing a stable contact point that mediates the support function. It supplements the two-point mop support by adding a third contact point that enhances stability without requiring complex structural modifications
2Device complexity
If the robot cleaner moves via rotation of a pair of left and right mops, then the structure is simple, but the frictional force varies frequently making it difficult to travel straight
Solution Approach 1:
The rolling member serves as a mediator for propulsion, working in conjunction with the rotating mops to provide more consistent frictional force. Its rolling contact supplements the variable friction from the mops, enabling straighter travel without increasing overall structural complexity
Solution Approach 2:
The system changes the contact mechanism parameter from purely rotating mop contact to a combination of rotating mop contact and rolling member contact. This parameter change provides more stable frictional force characteristics for straight-line travel
3Device complexity
If the robot cleaner moves via rotation of a pair of left and right mops, then the structure is simple, but traveling speed and traveling route are limited
Solution Approach 1:
The system dynamically combines two different locomotion mechanisms: rotation of mops and rolling of the rolling member. This dynamic combination allows the cleaner to achieve variable speeds and navigate different routes by coordinating the operation of these two mechanisms, enhancing adaptability without significantly increasing structural complexity
4Device complexity
If the robot cleaner moves via rotation of a pair of left and right mops, then the structure is simple, but it is difficult to perform mopping operation without rotating in place or moving linearly
Solution Approach 1:
The cleaning system is segmented into two independent modules: the first cleaning module with rotating mops for propulsion and the second cleaning module with the rolling member for supplemental cleaning. This segmentation allows the rolling member to perform mopping operations independently or in conjunction with the rotating mops, enabling cleaning without mandatory rotation or linear movement
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design improves stability, enables straight travel, increases maximum speed, and allows for efficient mopping operations, including wet and dry cleaning, by distributing load effectively and utilizing a rolling member to supplement mopping and reduce moisture left on the floor.
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.
