Detachable Spin Mop Module for Uneven Floor Wiping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaners face challenges in efficiently wiping uneven surfaces and maintaining stable rag attachment, with cumbersome rag detachment and replacement processes, and limited ability to perform both dry-type and wet-type cleaning effectively.
Innovation Solution
A robot cleaner design featuring a detachable mop module with a pair of spin mops that rotate clockwise or counterclockwise, a tilting frame for suspension, and a water supply system, allowing for easy rag replacement and stable floor contact, along with a mop driving unit and slave joint for efficient rotation and water delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rag surface is tilted downward and outward to contact the floor, then the cleaner can perform wiping operation, but the rag attachment becomes unstable and replacement is cumbersome
Solution Approach 1:
The mop module is divided into separable components including the rotation member, rag surface, and attachment mechanism. This allows the rag to be easily detached and replaced by simply separating the mop module from the cleaner body, resolving the cumbersome replacement issue while maintaining stable attachment during operation through the designed connection interface.
2Device complexity
If a fixed cleaning mechanism is used, then the structure is simple, but it cannot efficiently handle uneven surfaces
Solution Approach 1:
The cleaning mechanism transitions from a fixed structure to a dynamic rotating system. The rotation member spins the rag surface, enabling it to adapt to uneven floor surfaces through rotational motion while maintaining relatively simple overall structure. The rotation allows the rag to conform to surface variations without requiring complex adjustable mechanisms.
3Adaptability or versatility
If separate dry-type and wet-type cleaning devices are used, then each device is optimized for its function, but the overall system becomes complex and less versatile
Solution Approach 1:
The mop module is designed as a multi-functional component that can perform both dry-type wiping and wet-type cleaning operations. The same rotation member and rag surface configuration handles both dry and wet cleaning needs, eliminating the requirement for separate specialized devices and simplifying the overall system while maintaining versatility.

AI summary
A cleaner includes: a body which forms an outer appearance; and a mop module which is detachably connected to the body. The mop module includes: a pair of spin mops which contacts a floor while rotating clockwise or counterclockwise when viewed from a top; and a module housing which connects the pair of spin mops. The cleaner may travel autonomously due to the rotation of the spin mops.
