Reversible Housing Surface Cleaner for Floor and Elevated Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaners are limited in their ability to perform multiple uses, as they cannot effectively clean both floor surfaces and surfaces at a distance, such as vehicle underbodies, due to their size and design, which restricts their operational flexibility and efficiency.
Innovation Solution
A surface cleaner with a cup-shaped, cylindrical housing that is 180° reversible, allowing the rotor arm and spray nozzles to pivot from a downward-facing position for floor cleaning to an upward-facing position for cleaning surfaces at a distance, using a single chassis and non-reversible swivel castors or sliding elements for both modes, and an articulated high-pressure connection that remains unchanged during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a surface cleaner uses two different chassis to enable multiple cleaning modes (floor and wall/ceiling), then versatility is improved, but device complexity and size increase, preventing cleaning of closely spaced surfaces
Solution Approach 1:
The patent applies universality by designing a single chassis that can support multiple cleaning modes (floor cleaning, wall cleaning, ceiling cleaning) through the 180° reversible housing. The housing can be rotated to change the orientation of the rotor arm and spray nozzles, allowing one device to perform functions that previously required two separate chassis configurations.
2Stability of the object's composition
If the housing is made large to ensure stable support on the floor surface, then stability is improved, but the ability to clean closely spaced surfaces is reduced
Solution Approach 1:
The patent applies dynamics by making the housing reversible through 180° rotation. This dynamic capability allows the device to adapt its orientation based on the cleaning task, enabling it to maintain stability on the floor when needed while also being able to reach elevated surfaces or fit into narrow spaces by rotating the housing to a different orientation.
3Adaptability or versatility
If the high-pressure inlet is repositioned for each operating mode, then adaptability is improved, but ease of operation deteriorates due to additional reconnection effort
Solution Approach 1:
The patent applies merging by integrating the high-pressure inlet connection into a fixed position on the chassis that remains accessible regardless of the housing orientation. The articulated joint allows the housing to rotate independently while maintaining a continuous high-pressure fluid supply, eliminating the need to reposition or reconnect the high-pressure inlet when changing cleaning modes.
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
Enables efficient cleaning of both floor and elevated surfaces with minimal manufacturing and maintenance effort, reducing the overall height for close-space cleaning and maintaining operational flexibility without the need for additional height or reconnection of the high-pressure inlet.
Implementation Method 1
a rotor arm in the interior of an approximately cylindrical housing is driven in rotation under the influence of a high-pressure medium and cleans the cleaning surface with its spray nozzles

AI summary
Surface cleaner with connection to a high-pressure medium, consisting of a cup-shaped, open-ended housing (11) in which at least one rotor arm (6) is rotatably mounted on a central pivot joint (5) in the housing, wherein one or more cleaning nozzles (27) are arranged on the rotor arm (6) and are connected to the high-pressure medium guided by the pivot joint (5) in a fluid-conducting manner, wherein for a second operating mode the housing (11) is designed to be reversible by 180 degrees, wherein the surface cleaner can be operated in at least two different operating modes, wherein the first operating mode consists of a surface cleaning operation with the housing (11) directed downwards towards a floor and the cleaning nozzles (27) arranged therein, and the second operating mode is designed as a cleaning operation in which the housing (11) turned by 180 degrees with the upwardly directed cleaning nozzles (27) is directed towards a cleaning surface arranged at a distance from the floor.characterized in that the surface cleaner has a chassis (8, 9, 17) for supporting the housing (11) in the first and second operating positions relative to the floor surface.
