Floor cleaning machine with separator device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning machines often struggle to provide an optimized cleaning result while maintaining easy handling, as they lack effective suction mechanisms and efficient dirt collection systems.
Innovation Solution
The floor cleaning machine incorporates a design where the muzzle walls of the suction channel are positioned in such a way that they immerse into the cleaning roller's stocking, creating an optimized suction result. Additionally, a dirt liquid container is provided, connected to a separator device, to effectively collect and separate dirt and cleaning fluid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first outlet wall and second outlet wall are positioned to rest against or project into the cleaning roller bristles, then the suction effectiveness is improved, but the device complexity increases
Solution Approach 1:
The suction channel opening is nested within the cleaning roller bristles by positioning the first and second outlet walls to rest against or project into the bristles. This nesting arrangement allows the suction channel to utilize the space created by the bristle configuration, achieving effective suction contact without adding separate complex suction mechanisms.
Solution Approach 2:
The suction channel opening utilizes the vertical dimension by positioning the first outlet wall above the second outlet wall with respect to the direction of gravity. This vertical arrangement allows the opening to effectively interact with the rotating bristles in three-dimensional space, improving suction effectiveness through spatial optimization rather than increasing horizontal complexity.
2Power
If the muzzle walls immerse into the cleaning roller stocking, then the suction power is enhanced, but the ease of operation is reduced
Solution Approach 1:
The suction channel opening is designed to dynamically interact with the rotating cleaning roller bristles. As the roller rotates, different portions of the bristles pass through the opening, creating a continuous suction effect. This dynamic interaction allows the system to achieve high suction power through the rolling motion itself, rather than requiring a complex mechanical pressurization system that would compromise ease of handling.
3Productivity
If a separator device with dirty liquid container is added, then the dirt collection efficiency is improved, but the device complexity increases
Solution Approach 1:
The separator device acts as an intermediary between the suction channel and the collection container. It receives the suction flow containing dirt and cleaning fluid, separates the components, and directs them to appropriate destinations. This intermediary function improves dirt collection efficiency by ensuring proper separation and collection, while the modular design of the separator device allows it to be integrated without excessively increasing overall system complexity.
