Cleaning device with a motor-driven oscillating plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices require users to manually grasp and slide the carrier plate onto the oscillating plate for attachment or detachment, leading to contact with cleaning fluid and dirt.
Innovation Solution
The latching element and spring element are designed to be separate from the oscillating and carrier plates, allowing for attachment and detachment without manual handling, using a spring-loaded mechanism where the latching element engages behind an undercut, enabling a secure, play-free connection and allowing the carrier plate to move in sync with the oscillating plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the support plate is rigidly connected to the vibrating plate using manual sliding attachment, then the connection is simple and direct, but the user must manually grasp and slide the plates, leading to contact with cleaning fluid and dirt
Solution Approach 1:
The fastening system is designed to attach and detach automatically through spring-loaded locking elements that engage with receiving elements on the support plate. The user simply places the cleaning device onto the support plate, and the spring-loaded locking elements automatically snap into place, eliminating the need for manual grasping and sliding of the plates.
Solution Approach 2:
Spring-loaded locking elements serve as intermediaries between the vibrating plate and support plate. These locking elements with their undercuts create a mechanical interface that automatically engages when the plates are brought together, mediating the connection process without requiring direct manual manipulation of the plates themselves.
2Device complexity
If mounting rails are used to connect the support plate to the vibrating plate, then the connection structure is simple, but the user must guide the support plate with their hand during attachment, resulting in contact with contaminants
Solution Approach 1:
The spring-loaded locking elements with undercuts create a self-aligning and self-latching connection system. When the vibrating plate is placed onto the support plate, the locking elements automatically engage with the receiving elements without requiring manual guidance, making the system self-servicing during the attachment process.
3Extent of automation
If a spring-loaded locking mechanism with undercuts is used, then automatic attachment is achieved without manual handling, but the fastening system becomes more complex
Solution Approach 1:
The fastening system is segmented into discrete, modular components: individual spring-loaded locking elements on the vibrating plate and corresponding receiving elements on the support plate. This segmentation allows each component to be simple in design while the combination provides automated functionality, reducing overall system complexity.
Solution Approach 2:
The spring-loaded locking elements serve multiple functions: they provide the locking mechanism, guide the alignment during attachment, and ensure firm connection through the undercut engagement. This multi-functionality reduces the need for additional separate components, keeping the overall system relatively simple despite the automated capability.

AI summary
The invention relates to a cleaning device (1), in particular for a wet cleaning device (2), with a motor-driven vibrating plate (3) and a support plate (4) connectable to the vibrating plate (3) for receiving a cleaning element (5), wherein the vibrating plate (3) and the support plate (4), in relation to a connected state, have corresponding fastening means (6, 7) on mutually facing plate sides, wherein a fastening means (6, 7) of the vibrating plate (3) and a fastening means (6, 7) of the support plate (4) form a pair of fastening means (8, 9) and wherein the pair of fastening means (8, 9) has, on the one hand, a locking element (11) displaceable against a restoring force of a spring element (10), and, on the other hand, a receiving element (13) having an undercut (12) for receiving the locking element (11).To achieve convenient fastening of the oscillating plate (3) and the support plate (4), it is proposed that, in a top view of the facing plate sides, an end region (27) of the locking element (11) is exposed on one plate side and an insertion ramp (28) of the receiving element (13) which complements the locking element (11) to the pair of fasteners (8, 9) is exposed on the other plate side, and that, in a state in which the oscillating plate (3) and the support plate (4) are fastened together, in a vertical section perpendicular to a plane of oscillation of the oscillating plate (3) the receiving element (13) surrounds the locking element (11) on the outside.
