Docking Station Self-Cleaning for Autonomous Floor Cleaning Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Floor cleaning machines can become fouled and lose effectiveness due to soil buildup on their cleaning heads, especially in environments with high olefinic content like grease, which is not detected by human operators during extended autonomous operation.
Innovation Solution
A docking station that includes flushing orifices and brushes to deliver a device cleaning fluid to the cleaning head and exterior surfaces of the floor cleaning machine, allowing for self-cleaning during docking, which can use the same cleaning fluid as the machine or a different composition like a degreaser.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the floor cleaning machine operates autonomously for extended periods, then productivity is improved, but the cleaning head becomes fouled with soil buildup reducing cleaning effectiveness
Solution Approach 1:
The docking station automatically cleans the cleaning head of the floor cleaning machine using flushing orifices that deliver cleaning fluid to the cleaning head, enabling the system to maintain itself without human intervention during autonomous operation
Solution Approach 2:
The docking station performs cleaning of the cleaning head before the machine resumes its next cleaning cycle, preventing soil buildup from accumulating to levels that would compromise cleaning effectiveness
2Productivity
If the cleaning head contacts the floor surface to remove soil, then cleaning performance is improved, but the cleaning head itself becomes contaminated with adhering soil
Solution Approach 1:
The docking station uses the same cleaning fluid that the machine applies to floors to clean the cleaning head itself, converting the cleaning fluid into a dual-purpose substance that both cleans floors and maintains the cleaning head
Solution Approach 2:
The system automatically cleans its own cleaning head through the docking station's flushing orifices, eliminating the need for manual cleaning and preventing soil buildup that would otherwise require operator intervention
3Device complexity
If the docking station provides only power recharging, then device complexity is minimized, but cleaning effectiveness deteriorates due to undetected soil buildup
Solution Approach 1:
The docking station is designed to perform multiple functions including power recharging, cleaning fluid supply, waste removal, and cleaning head maintenance, allowing a single device to handle all aspects of machine servicing
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The docking station ensures the floor cleaning machine maintains effective cleaning performance by removing build-up soil from the cleaning head, preventing it from deteriorating and ensuring continued cleanliness of floor surfaces.
Implementation Method 1
The docking station can include one or more flushing orifices arranged to deliver a device cleaning fluid to the cleaning head and exterior surfaces of the floor cleaning machine
Implementation Method 2
The docking station may or may not also have rotating and/or moving brushes to clean the cleaning head of the floor cleaning machine, an underside of the machine, and/or an exterior surface of the machine

AI summary
A floor cleaning system may include a docking station to which an autonomous floor cleaning machine can dock between cleaning operations. The docking station can provide power to the autonomous floor cleaning machine to recharge the batteries of the machine when not in use. The docking station may also supply fresh cleaning fluid to the floor cleaning machine and remove collected waste from the machine. In practice, the floor cleaning machine may itself become dirty over repeated use, such as when cleaning greasy floor surfaces. Accordingly, the docking station may include flushing orifices to clean the floor cleaning machine itself, such as with a degreasing composition.
