Reciprocating Floor Cleaner With Vacuum Dust Pickup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning robots are ineffective in removing stain marks, footprints, and fine particles due to limited cleaning cloth wiping frequency, dust accumulation, and inability to handle uneven floors and slots.
Innovation Solution
An automatic cleaning machine with a reciprocating wiping mechanism, vacuum device, and spray system, equipped with sensors and a control system for obstacle detection and path planning, to increase wiping frequency, collect dust, and maintain optimal cleaning cloth moisture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a cleaning cloth is pulled by the robot to mop the floor, then the robot can clean the floor surface, but the wiping frequency is low and dust accumulates in front of the cleaning cloth
Solution Approach 1:
The patent applies a reciprocating mechanism that dynamically moves the cleaning cloth back and forth in addition to the robot's forward motion. This dynamic reciprocating action increases the wiping frequency significantly compared to simple pulling, while the vacuum device simultaneously removes dust accumulation by suctioning particles from the cleaning path.
Solution Approach 2:
The patent merges the wiping function with a vacuum device in a single cleaning system. The vacuum device is positioned to work in conjunction with the reciprocating cleaning cloth, combining mechanical wiping action with air suction to prevent dust accumulation and improve overall cleaning effectiveness.
2Productivity
If water is sprayed onto the floor and a rubber scraper recycles the water, then stain marks and footprints can be cleaned, but water is left on uneven floors and the robot cannot handle slots
Solution Approach 1:
The patent extracts the water spraying and recycling functions from the cleaning system, retaining only the essential reciprocating wiping mechanism and vacuum device. This simplification removes the problem of water accumulation on uneven surfaces while preserving effective stain cleaning through increased wiping frequency and vacuum dust removal.
Solution Approach 2:
The patent uses a disposable-like approach by continuously supplying fresh cleaning cloth through the reciprocating mechanism rather than recycling water. The vacuum device continuously removes dust and debris, effectively creating a fresh cleaning action with each pass without needing to recycle cleaning fluid.
3Productivity
If a center brush or cleaning cloth is used for mopping, then dust can be removed, but fine particles and dust in slots are not effectively collected
Solution Approach 1:
The patent employs pneumatic principles through the vacuum device that uses air suction to remove dust and fine particles. The vacuum system creates negative pressure to draw in and collect fine particles that mechanical brushing alone cannot effectively remove, including those in slots and crevices.
Solution Approach 2:
The reciprocating motion of the cleaning cloth combined with the vacuum device creates a dynamic cleaning action that effectively loosens and removes fine particles from various surface types, including slots and uneven areas, significantly improving particle collection capability.
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
The machine achieves high-efficiency cleaning by increasing wiping frequency, effectively collecting dust and improving cleaning of stain marks and fine particles on various floor types, including uneven surfaces.
Implementation Method 1
The dust on the floor is sucked into the inlet by an air flow
Implementation Method 2
a spray device used for spraying water on the floor
Implementation Method 3
The roller is located between the brush plate and the housing, and rotates on the brush plat or the base, so as to reduce the frictional resistance to the relative motion of the brush plate and the base
