Floor Cleaning Roller Ejection Mechanism for Hygienic Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning devices complicate the removal of the floor cleaning roller, requiring manual handling and potential exposure to dirt, and often necessitate additional disassembly.
Innovation Solution
A floor cleaning device with a housing that includes an insertion opening and bearing elements, featuring a radial ejection mechanism that converts radial movement into axial displacement of the roller, allowing for easy and hygienic removal without manual contact or additional disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the floor cleaning roller is held in bearing elements fixed to the housing, then the roller is securely supported during operation, but the roller becomes difficult to remove requiring additional disassembly
Solution Approach 1:
The bearing elements are designed to change their functional state between operation and removal. During operation, they securely hold the roller; during removal, they can be displaced or deactivated to release the roller, allowing the system to adapt between these two states
2Reliability
If a traditional locking mechanism is used to secure the roller, then the roller remains fixed during operation, but the removal process requires manual handling and exposes the user to dirt
Solution Approach 1:
The ejection mechanism is designed to automatically perform the roller removal function when activated. The user simply triggers the ejection element, which then self-executes the complete removal process, eliminating the need for manual handling of the dirty roller
Solution Approach 2:
The ejection element acts as an intermediary mechanism between the user and the roller. Instead of the user directly contacting the roller for removal, the ejection element mediates the process by applying force to displace the roller through the bearing elements
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
Facilitates quick, simple, and hygienic removal of the floor cleaning roller, minimizing user exposure to dirt and eliminating the need for additional disassembly, thereby reducing the time required for roller changes.
Implementation Method 1
a gear mechanism for converting the radial movement of the ejection element into a substantially purely axial displacement of the floor cleaning roller

AI summary
A floor cleaning device (2) comprising a housing (3) with an insertion opening (4) through which a floor cleaning roller (5) can be removed from and reinserted into the housing (3), two housing-fixed bearing elements (6a, 6b) for supporting the floor cleaning roller (5), two counter-bearing elements (8a, 8b) arranged on opposite end faces of the floor cleaning roller (5) and corresponding to the bearing elements (6a, 6b), and an ejection element that can be actuated radially to the floor cleaning roller (5), wherein in a rest position of the ejection element the floor cleaning roller (5) with its counter-bearing elements (8a, 8b) is held in the bearing elements (6a, 6b), wherein the vacuum cleaner nozzle (1) also has a gear for converting the radial movement of the ejection element into an axial movement of the floor cleaning roller (5), and the ejection element is movable from the rest position to an intermediate position.In an intermediate position of the ejection element, the floor cleaning roller (5) is axially displaced by means of the gearbox, thereby axially releasing the floor cleaning roller (5) from a housing-fixed bearing element (6a). The invention enables particularly simple, quick, and hygienic removal of a floor cleaning roller.
