Floating Cleaning Element Vacuum Attachment for Uneven Surface Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners face challenges in maintaining effective contact between cleaning elements and uneven surfaces, leading to reduced cleaning effectiveness due to inadequate force exertion and potential loss of contact between the suction conduit or cleaning pad and the surface.
Innovation Solution
A vacuum attachment with a floating cleaning element supported by a bias mechanism, allowing it to adapt to surface contours, is designed to maintain contact with the surface by using a support structure that floats relative to the housing, ensuring continuous debris collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cleaning sheet or pad is fixed relative to the suction conduit or nozzle, then the structure is simple and easy to manufacture, but the cleaning effectiveness is reduced on uneven surfaces due to loss of contact
Solution Approach 1:
The cleaning element support structure is made movable relative to the suction conduit through a sliding coupling mechanism, allowing dynamic adaptation to surface contours. The support structure can slide along the longitudinal axis of the suction conduit, enabling the cleaning element to maintain contact with uneven surfaces while the suction conduit remains relatively fixed.
Solution Approach 2:
The vacuum cleaner is divided into functionally independent components: the suction conduit, the cleaning element support structure, and the cleaning element itself. This segmentation allows each component to perform its specific function independently, with the support structure acting as an intermediary that enables relative movement between the suction conduit and cleaning element.
2Adaptability or versatility
If the cleaning element support structure is fixed to the housing, then the structure is stable and simple, but the cleaning element cannot adapt to surface contours
Solution Approach 1:
The sliding coupling mechanism enables dynamic adjustment of the cleaning element support structure's position relative to the housing, allowing the cleaning element to adapt to various surface contours while maintaining a relatively simple mechanical connection through sliding elements.
Solution Approach 2:
The sliding coupling mechanism acts as an intermediary between the fixed housing and the movable cleaning element support structure, facilitating relative movement while maintaining structural connection. This intermediary mechanism allows adaptability without requiring complete decoupling or complex articulated joints.
3Productivity
If the suction conduit or cleaning pad loses contact with the surface on uneven terrain, then the structure remains simple, but debris collection efficiency is reduced
Solution Approach 1:
The cleaning element support structure is designed to move independently relative to the suction conduit, allowing it to dynamically follow surface contours and maintain continuous contact with the cleaning surface, thereby ensuring consistent debris collection efficiency on uneven terrain.
Solution Approach 2:
The support structure allows different parts of the vacuum cleaner to have different degrees of freedom: the suction conduit maintains its structural integrity and suction function, while the cleaning element support structure provides local adaptability to surface variations, optimizing debris collection at the contact point.
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 floating cleaning element improves cleaning effectiveness by maintaining contact with the surface, even on uneven surfaces, enhancing the overall cleaning performance of vacuum cleaners.
Implementation Method 1
At least a first bias mechanism is configured to bias the support structure away from the housing such that the support structure floats with respect to the housing during use on a surface being cleaned

AI summary
A vacuum cleaner attachment generally includes a cleaning element that floats relative to a suction conduit of the vacuum cleaner attachment. The cleaning element is supported on a support structure that is movably coupled to a housing and is biased towards a floor, for example, as a result of the weight of the cleaning element support structure. The cleaning element may be permanently attached to the support structure or may be a removable or disposable pad or sheet attached to the support structure. The floating cleaning element may be supported between the suction conduit and one or more wheels of the vacuum cleaner attachment. The vacuum cleaner attachment may be removably attached to a vacuum cleaner, for example, to be used interchangeably with other surface cleaning heads.
