Floor cleaning machine and method for cleaning a floor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning machines often leave uncleaned areas between parallel cleaning path sections due to limitations in their movement and engagement with the floor surface, which hinders complete cleaning.
Innovation Solution
A floor cleaning machine with a chassis that can rotate perpendicular to the floor surface, equipped with a cleaning device that can be positioned to maintain a cleaning mirror distance of less than or equal to half the cleaning mirror width, allowing for rotational movement and overlap of cleaning areas between parallel path sections, ensuring comprehensive coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the cleaning device is positioned with a larger cleaning mirror distance from the axis of rotation, then the stability of the cleaning device is improved, but the cleaning completeness deteriorates due to uncleaned areas between parallel cleaning path sections
Solution Approach 1:
The patent applies parameter changes by optimizing the cleaning mirror distance to be less than or equal to half the cleaning mirror width. This specific parameter adjustment ensures that when the cleaning device rotates between parallel cleaning path sections, the cleaning areas overlap sufficiently to eliminate uncleaned regions while maintaining stable operation.
2Manufacturing precision
If the cleaning device is positioned closer to the axis of rotation, then the cleaning completeness is improved by reducing uncleaned areas, but the stability of the cleaning device deteriorates
Solution Approach 1:
The patent resolves this contradiction by establishing an optimal parameter range for the cleaning mirror distance (less than or equal to half the cleaning mirror width). This parameter optimization achieves the dual goal of improving cleaning completeness through better area overlap while maintaining adequate stability for the cleaning device during rotation and operation.
3Area of moving object
If the cleaning device engages with the floor surface at a larger distance from the axis of rotation, then the cleaning area width is increased, but the overlap between adjacent cleaning path sections is reduced
Solution Approach 1:
The patent applies parameter changes by constraining the cleaning mirror distance to be less than or equal to half the cleaning mirror width. This parameter relationship ensures that even as the cleaning area width increases, sufficient overlap is maintained between adjacent cleaning path sections, guaranteeing complete cleaning coverage without uncleaned areas.
4Productivity
If the cleaning device is positioned to maximize cleaning area width, then the productivity is improved, but the cleaning completeness deteriorates due to gaps between cleaning path sections
Solution Approach 1:
The patent resolves this contradiction by optimizing the parameter relationship between cleaning mirror distance and cleaning mirror width. By maintaining the cleaning mirror distance at less than or equal to half the cleaning mirror width, the system achieves both high productivity through efficient cleaning area coverage and complete cleaning coverage without gaps between parallel cleaning path sections.
