Detachable Fluid Container Layout for Easier Floor Cleaner Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning devices with combined cleaning and dirty liquid containers complicate handling, as they often require simultaneous refilling and emptying, leading to cumbersome operation and increased user load during use.
Innovation Solution
The design separates the cleaning and dirty liquid containers, allowing them to be detached from each other and the handle, facilitating independent filling and emptying, with the cleaning liquid container arranged laterally for easy access and a bypass suction unit positioned below to reduce user load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cleaning liquid container and dirty liquid container are designed as a common container assembly that is detachably connected to the handle, then the container assembly can be separated for filling and emptying operations, but the handling becomes more difficult when only one container needs to be filled or emptied without the other
Solution Approach 1:
The common container assembly is segmented into two separable parts: the cleaning liquid container and the dirty liquid container. Each container can be independently detached from the other while remaining connected to the handle, allowing users to fill or empty only the required container without moving the entire assembly, thus resolving the contradiction between ease of operation and device complexity
2Ease of operation
If the cleaning liquid container is arranged laterally next to the dirty liquid container, then the two containers are at practically the same height reducing user load changes, but the lateral arrangement requires more horizontal space on the handle
Solution Approach 1:
The containers are arranged laterally (horizontally) rather than vertically stacked, changing the spatial dimension from vertical to horizontal arrangement. This lateral positioning ensures both containers remain at the same height relative to the floor, maintaining consistent user load during operation, while the handle design accommodates this horizontal space requirement through its structural configuration
3Ease of operation
If the cleaning liquid container can be separated from the dirty liquid container while maintaining connection between the dirty liquid container and the handle, then the cleaning liquid container can be filled independently, but the separation mechanism becomes more complex
Solution Approach 1:
The connection system is segmented into two independent attachment points: one connecting the cleaning liquid container to the handle, and another connecting the dirty liquid container to the handle. This segmentation allows the cleaning liquid container to be independently detached and reattached without affecting the dirty liquid container's connection to the handle, enabling independent filling operations while using a relatively simple separation mechanism
Solution Approach 2:
The handle is designed with universal connection features that can accommodate both containers independently. The same connection interface is used for both the cleaning liquid container and the dirty liquid container, allowing either container to be attached or detached without requiring different mechanisms, thus simplifying the overall separation system while enabling independent operation
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
This configuration simplifies handling by allowing separate management of containers, reducing the weight and load on the user during operation and enhancing convenience by maintaining a consistent load distribution.
Implementation Method 1
a suction unit arranged next to the brush roller and facing in the forward cleaning direction with which a suction flow can be generated

AI summary
The invention relates to a floor cleaning device having a brush head, in which a brush roller is rotatably supported and having at least one suction nozzle disposed next to the brush roller, and a handle held pivotally on the brush head, a suction unit being disposed on said handle, and a cleaning fluid container for cleaning fluid that can be applied to the floor surface to be cleaned, and a dirty liquid container for receiving dirty liquid taken up from the floor surface by the suction unit, wherein the cleaning fluid container and the dirty liquid container together form a container assembly that is detachably connected by the handle. In order to refine the floor cleaning device such that it is easy to handle, it is proposed according to the invention to detachably connect the cleaning fluid container to the dirty liquid container.
