Liquid-permeable brush roll for use with cleaners including robotic cleaners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning devices, particularly robotic cleaners, face challenges in effectively performing wet cleaning operations due to limitations in distributing and managing cleaning fluids, which affects the suspension and removal of contaminants from surfaces.
Innovation Solution
A liquid-permeable brush roll with a main body having a cavity for storing cleaning fluid and weep holes for fluid distribution, coupled with a drive mechanism for rotation, enhances the cleaning process by allowing the fluid to be applied and agitated across the surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional brush roll is used in wet cleaning operations, then the structure is simple and easy to manufacture, but the cleaning fluid distribution is inconsistent and contamination removal effectiveness is reduced
Solution Approach 1:
The brush roll incorporates a porous distribution member with multiple porous members that allow cleaning fluid to pass through uniformly. The porous structure enables consistent fluid distribution across the brush roll surface while maintaining a relatively simple overall design that integrates with conventional vacuum cleaner architectures.
2Quantity of substance
If cleaning fluid is stored in a separate reservoir, then the fluid storage capacity is sufficient, but the device complexity increases and space is consumed
Solution Approach 1:
The distribution member is designed to function both as a fluid distribution mechanism and as a storage component. The porous members can hold cleaning fluid within their structures, eliminating the need for a completely separate reservoir system while maintaining adequate fluid capacity for effective wet cleaning operations.
Solution Approach 2:
The distribution member serves multiple functions: it distributes cleaning fluid uniformly through its porous structure, stores cleaning fluid within the porous members, and integrates with the brush roll to provide both cleaning and fluid management capabilities in a single component.
3Productivity
If a liquid-permeable brush roll with cavity and weep holes is used, then the cleaning effectiveness is improved through consistent fluid application, but the manufacturing complexity increases
Solution Approach 1:
The use of porous members with uniform pore structures allows for consistent cleaning fluid distribution, which directly improves cleaning effectiveness. The porous structure can be manufactured using established techniques, and the distribution member can be integrated into the brush roll assembly with standard manufacturing processes.
