Detachable Spin Mop Module for Uneven Floor Robot Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robot cleaners face difficulties in increasing friction with the floor for effective wiping, are inconvenient for rag attachment and detachment, and struggle with uneven surfaces, requiring separate detachment of multiple rags and lacking a stable suspension system for smooth operation.
Innovation Solution
A robot cleaner design featuring a detachable mop module with spin mops that rotate for increased friction, a modular connection system for easy rag attachment and detachment, and a tilting frame for suspension and water delivery, allowing for both dry and wet-type cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a general cleaner uses a heavy body structure, then stability is improved, but ease of operation deteriorates because users must turn the heavy cleaner over to attach or detach rags
Solution Approach 1:
The cleaner is divided into a main body and a detachable mop module. The mop module can be easily removed and attached without turning over the entire cleaner, while the main body remains stable during operation. This segmentation allows the heavy stable structure to be separated from the lightweight removable cleaning component.
2Area of stationary object
If multiple rags are used on the cleaner, then cleaning coverage is improved, but device complexity increases because each rag must be detached separately
Solution Approach 1:
Multiple rags are integrated into a single detachable mop module. All rags can be removed together by detaching one module, rather than separately removing each rag. This merging simplifies the detachment process while maintaining multiple cleaning surfaces for comprehensive coverage.
3Manufacturing precision
If the cleaner uses a fixed rigid structure, then manufacturing precision is improved, but adaptability deteriorates because it cannot handle uneven floor surfaces
Solution Approach 1:
The cleaner incorporates a tilting mop module that can dynamically adjust its angle relative to the main body. This allows the cleaning head to adapt to uneven floor surfaces while the main body maintains its precise manufactured structure. The dynamic tilting mechanism provides flexibility without compromising overall structural precision.
4Ease of operation
If the cleaner uses a simple connection structure for the mop module, then ease of operation is improved, but reliability deteriorates because the connection may not be stable during cleaning
Solution Approach 1:
The connection structure uses localized engagement features at specific points on the mop module and main body. These localized connection points provide stable mechanical engagement during cleaning operations, while the overall detachment process remains simple. The local quality of the connection points ensures reliability without complicating the overall operation.
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
Enhances wiping efficiency, simplifies rag replacement, provides stable operation on uneven surfaces, and maintains effective cleaning performance with improved friction and suspension mechanisms.
Implementation Method 1
increase a frictional force between a rag and a floor surface so that a cleaner may wipe and travel effectively
Implementation Method 2
When the general cleaner wipes an uneven floor surface, there is a problem in that it is difficult to wipe a concave portion, and shock at the portion may not be absorbed, thereby causing failure to the device
