Solution Overview
Problem
Existing robot cleaners face challenges in efficiently wiping and cleaning surfaces due to limitations in their design and functionality, particularly in autonomously navigating and effectively removing foreign substances from floors.
Innovation Solution
A robot cleaner design that incorporates a mop module with rotating spin mops and a collection module, which work together to autonomously navigate and clean surfaces by rotating to generate frictional forces for movement and using water for effective wiping, while the collection module removes foreign substances through sweeping and suction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If robot cleaners use spinning rotation members with tilted rag surfaces for cleaning, then the cleaner can travel and clean simultaneously, but only a portion of the rag surfaces contacts the floor reducing cleaning effectiveness
Solution Approach 1:
The spin mop module allows the mop head to rotate dynamically during movement, enabling the entire rag surface to contact the floor progressively rather than having a fixed tilted configuration. This dynamic rotation ensures complete utilization of the rag surface for cleaning while maintaining the ability to travel.
Solution Approach 2:
The cleaning system is divided into separate functional modules: a spin mop module with rotating mop head, a collection module with sweeping and suction functions, and a water supply module. This segmentation allows each module to optimize its specific function while working together, improving overall cleaning effectiveness without excessive complexity.
2Productivity
If robot cleaners use a combination of sweeping and suction for foreign substance removal, then cleaning effectiveness improves, but device complexity increases
Solution Approach 1:
The collection module merges sweeping and suction functions into a single integrated unit. The rotating collection member performs sweeping while the suction device simultaneously removes foreign substances, combining two cleaning mechanisms into one compact module that improves effectiveness without proportionally increasing complexity.
Solution Approach 2:
The collection module serves multiple functions: it collects foreign substances through sweeping, removes them through suction, and can be detached for maintenance. This multi-functionality maximizes cleaning effectiveness while keeping the overall device structure manageable through modular design.
3Ease of repair
If the spin mop module is detachably connected to the body, then ease of maintenance improves, but connection reliability may decrease
Solution Approach 1:
The cleaner is divided into detachable modules including the spin mop module and collection module that can be separately removed for maintenance. This segmentation enables easy access to individual components for cleaning and maintenance while maintaining reliable connections during operation through proper coupling mechanisms.

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 robot cleaner achieves efficient surface wiping and cleaning by autonomously navigating and using a combination of rotational movement and water to remove dirt, enhancing cleaning efficiency and adaptability.
Implementation Method 1
a spin mop (41) that rotates about a rotation axis (Osa, Osb) which extends substantially vertically
Implementation Method 2
travels by rotation of the first rotation member and the second rotation member, while only a portion of the rag surfaces, which are fixed to the first rotation member and the second rotation member, contacts the floor due to the tilt
Implementation Method 3
using water for effective wiping
Implementation Method 4
the collection module removes foreign substances through sweeping and suction

AI summary
A cleaner includes a body which forms an outer appearance; a mop module having at least one rag part which is provided to wipe a floor while rotating; and a detaching module comprising at least one catching portion which detachably catches the mop module to the body, and a manipulation button which is exposed outside, wherein when the manipulation portion is touched, the catching portion releases catching of the mop module.
