Front-Mounted Split Hopper Design for Compact Floor Cleaning Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning machines require laborious and time-consuming manual emptying of debris hoppers, which impede cleaning operations and complicate maneuverability due to rear-mounted hopper designs or complex mechanisms that extend the machine's length.
Innovation Solution
A floor cleaning machine with a high dump hopper system featuring split debris hoppers located near the front, connected to a lift system that moves them from a stowed position underneath the machine to an elevated position for easy emptying, allowing compact design and improved maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If debris hoppers are mounted at the rear of the machine, then debris collection capacity is improved, but maneuverability deteriorates and emptying becomes laborious
Solution Approach 1:
The patent inverts the conventional rear-mounted hopper design by positioning the debris hopper at the front of the machine. This allows the hopper to be easily emptied by simply driving over a dumpster or waste container, eliminating the need for manual lifting and emptying operations. The front-mounted position also improves maneuverability while maintaining adequate debris collection capacity.
2Ease of operation
If complex mechanisms are used to extend machine length for hopper emptying, then emptying capability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the hopper emptying function from complex mechanical mechanisms and simplifies it to a basic driving operation. By positioning the hopper at the front, the emptying action is reduced to simply driving the machine forward over a waste container, eliminating the need for lifts, extensions, or other complex emptying mechanisms.
3Quantity of substance
If hopper design extends machine length, then debris capacity is improved, but compact design is compromised
Solution Approach 1:
The patent changes the spatial arrangement from longitudinal extension to vertical stacking. The hopper is positioned above the front wheel assembly area, utilizing the vertical dimension rather than extending the machine length horizontally. This maintains a compact machine footprint while providing adequate debris collection capacity.

AI summary
Systems and methods include a high dump hopper system wherein a debris hopper can be split into two hoppers for positioning adjacent a wheel of the floor cleaning machine. The hoppers, split or not, can be located near the front of the machine such that the overall length of the floor cleaning machine need not be extended. A splitter can be positioned proximate the floor cleaning mechanism to drive debris into the split hoppers. The hoppers, split or not, can be coupled to a common lifting system that can pull the hoppers out from under a chassis of the floor cleaning machine and then upwards for positioning relative to a refuse container. Furthermore, the orientation of the hoppers can be controlled to position openings for the hoppers in a desired location to prevent spilling and facilitate emptying.
