Segmented Suction Mouth for Floor Cleaners With Lower Fluid Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning machines lack an efficient mechanism for suctioning dirt while minimizing fluid loss and ensuring effective cleaning without causing abrasion or residual moisture issues.
Innovation Solution
The floor cleaning machine incorporates a suction channel system with adjustable mouth walls and a contact element that protrudes into the cleaning roller, creating a negative pressure zone for effective dirt suction while minimizing fluid loss, and features a rotating cleaning roller with grooves for enhanced dirt entrainment and a sweeping lip for coarse dirt pickup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the suction channel mouth is positioned close to the cleaning roller for effective dirt suction, then suction efficiency is improved, but fluid loss increases
Solution Approach 1:
The suction channel mouth is divided into two separate walls (first mouth wall and second mouth wall) that are spaced apart from each other. This segmentation allows the suction opening to be positioned close to the cleaning roller for effective dirt suction while the spaced walls prevent excessive fluid loss by creating a controlled suction zone.
2Productivity
If the cleaning roller rotates at high speed for efficient cleaning, then cleaning productivity is improved, but fluid loss and residual moisture increase
Solution Approach 1:
The segmented mouth structure with spaced walls creates a controlled suction field that captures dirt particles effectively while allowing the cleaning roller to rotate at high speeds. The spacing between walls prevents excessive fluid being drawn into the suction channel, reducing both fluid loss and residual moisture on the cleaned surface.
3Reliability
If the suction channel is positioned to maximize dirt pickup, then cleaning effectiveness is improved, but the risk of causing abrasion increases
Solution Approach 1:
By dividing the suction mouth into two spaced walls, the suction force is distributed and controlled more evenly across the cleaning roller surface. This prevents concentrated suction forces that could cause abrasion, while still maintaining effective dirt pickup through the spaced opening configuration.
