Removable Mop Roller Assembly for Dual-Function Autonomous Vacuum
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional autonomous cleaning systems are either single-functional, focusing on vacuuming or mopping, and are often clunky due to separate components for each functionality, failing to efficiently handle both types of messes effectively.
Innovation Solution
An autonomous vacuum with a dual-roller cleaning head that incorporates a removable mop roller core, capable of both dry and wet cleaning, utilizing a solvent to clean hard surfaces and ingesting waste into a single waste bag, with a solvent dispersion system and wringer for efficient debris management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate components are used for vacuuming and mopping functionalities, then each function can be optimized independently, but the system becomes clunky and complex with two distinct sets of components
Solution Approach 1:
The patent combines vacuuming and mopping functionalities into a single integrated cleaning head assembly. The cleaning head contains both a brush roller for vacuuming and a mop roller for mopping, allowing both functions to be performed by one unified structure rather than separate components, thereby reducing system complexity while maintaining functional optimization
Solution Approach 2:
The cleaning head is designed as a universal component that performs multiple cleaning functions. The single cleaning head can switch between vacuuming mode (using the brush roller) and mopping mode (using the mop roller), making the system versatile and eliminating the need for separate specialized components for each function
2Device complexity
If a fixed mop roller is used in the cleaning head, then the structure is simplified, but replacement of mop rolls requires external tools and is inconvenient
Solution Approach 1:
The mop roller assembly is segmented into separable components: the mop roller core, the mop roll (cleaning element), and the connector mechanism. This segmentation allows the mop roll to be easily detached and replaced from the core without requiring external tools, while the core remains integrated in the cleaning head, thus maintaining structural simplicity while enabling easy maintenance
Solution Approach 2:
The connection mechanism between the mop roller core and the cleaning head incorporates a dynamic release feature that allows the core to be quickly removed and reattached. This dynamic design enables tool-free replacement of mop rolls by simply detaching the core from the cleaning head, replacing the roll, and reattaching the core, thereby improving ease of operation without complicating the overall structure

AI summary
An autonomous vacuum leverages a dual-roller cleaning head, one for dry cleaning and another for wet cleaning. The autonomous vacuum utilizes vacuum force to ingest both dry waste and liquid waste from the cleaning head into the waste bag. The autonomous vacuum further comprises a cleaning head coupled to the vacuum motor, the cleaning head forming a mop roller cavity including a first end and a second end opposite the first end, wherein a mop opening exposes the mop roller cavity to an external environment. The cleaning head comprises a mop motor positioned at the first end of the mop roller cavity and including a driver clutch. The cleaning head further comprises mop roller core having a first end, a second end opposite to the first end, and an outer surface covered with a fabric material, the mop roller comprising a spring clutch positioned at the first end of the mop roller and removably couplable to the driver clutch of the mop motor.
