Autonomous floor cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous floor cleaners are limited in their ability to efficiently collect dirt around the entire perimeter and often push dirt instead of picking it up, lacking a comprehensive cleaning mechanism that combines sweeping and dusting actions.
Innovation Solution
An autonomous floor cleaner with a rotating top plate and sweeping elements that use ramps and guides to collect dirt into a central chamber, combined with a dusting cloth for enhanced cleaning and easy dirt disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing autonomous floor cleaners use a simple directional pushing mechanism, then the device complexity is low, but the cleaning effectiveness deteriorates as they push dirt instead of picking it up efficiently
Solution Approach 1:
The cleaning mechanism is segmented into multiple functional components: a rotating top plate with sweeping elements at the periphery, ramps for dirt transport, and a central collection chamber. This segmentation allows each component to perform a specific function (sweeping, directing, collecting) thereby improving overall dirt collection efficiency while maintaining manageable complexity through modular design
Solution Approach 2:
The invention transitions from a simple linear pushing mechanism to a rotational two-dimensional cleaning action. The top plate rotates to bring sweeping elements into contact with dirt around the entire perimeter, converting a one-dimensional pushing motion into a two-dimensional sweeping and collecting system that significantly improves dirt pickup capability
2Productivity
If existing autonomous floor cleaners use a single-direction cleaning approach, then the ease of operation is high, but the cleaning coverage deteriorates as they cannot clean around the entire perimeter effectively
Solution Approach 1:
The top plate is designed to rotate dynamically, bringing different peripheral sweeping elements into contact with the floor surface at different positions around the device. This dynamic rotation enables comprehensive perimeter cleaning coverage while the automatic rotation mechanism maintains ease of operation by eliminating the need for manual repositioning or complex user intervention
Solution Approach 2:
The rotating top plate structure serves multiple functions simultaneously: it provides structural support, enables perimeter-wide sweeping through rotation, directs dirt onto ramps, and facilitates collection in the central chamber. This multi-functionality improves cleaning coverage while simplifying the overall system by combining multiple functions into a single integrated mechanism

AI summary
An autonomous floor cleaner includes a base that is movable over a surface to be cleaned, a collection chamber associated with the base, and a rotating top mounted coupled with the base for rotation relative to the base, where the top carries at least one sweeping element for sweeping dirt on the surface to be cleaned toward the collection chamber.
