Floor Cleaning Machine with A Clearing Blade Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning machines face issues where protective lips rest on the floor surface, leading to poor cleaning results and increased maintenance costs due to wear, as they push fine dirt instead of collecting it and are not adaptable to varying conditions.
Innovation Solution
A floor cleaning machine equipped with a clearing blade arrangement and a guiding wheel that adjusts in height and position to prevent larger objects from entering the cleaning path while allowing fine dirt to be collected, featuring a flexible strip and adjustable parallelogram structure to maintain effective cleaning over uneven surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a protective lip rests on the floor surface to clear larger objects, then larger objects are cleared to the side, but fine dirt is pushed along and not collected, leading to poorer cleaning results
Solution Approach 1:
The protective lip is divided into multiple segments that can independently adjust their position. This allows each segment to adapt to different floor conditions, clearing larger objects while minimizing interference with fine dirt collection by the cleaning device.
Solution Approach 2:
The protective lip transitions from a static structure to a dynamic one with height adjustment capability. By adjusting the height of individual segments, the system can optimize performance for different scenarios - higher position for clearing objects, lower position for better dirt collection.
2Object-affected harmful factors
If a protective lip rests on the floor surface, then larger objects are cleared to the side, but the protective lip is subject to considerable wear, resulting in higher maintenance costs
Solution Approach 1:
The protective lip can be raised off the floor surface when not needed for clearing objects, eliminating unnecessary contact and wear. The height adjustment mechanism allows the lip to only contact the floor when required for its clearing function.
Solution Approach 2:
The height parameter of the protective lip is made variable rather than fixed. By changing the height parameter dynamically, the system reduces wear by minimizing floor contact while maintaining clearing effectiveness when needed.
3Device complexity
If a protective lip rests on the floor surface, then the configuration is simple, but it can only be adapted to a limited extent to the conditions in which the floor cleaning machine is used
Solution Approach 1:
The protective lip is segmented into multiple independently adjustable sections. This segmentation provides adaptability to different floor conditions while maintaining a relatively simple overall configuration that builds upon the basic protective lip concept.
Solution Approach 2:
The height-adjustable protective lip serves multiple functions - clearing larger objects at higher positions and working closer to the floor at lower positions. This multi-functionality increases adaptability to various usage conditions without requiring multiple separate components.
