Rotatable Head Cleaning Device for Mixed Media Debris Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hard floor cleaning devices struggle to efficiently handle mixed media debris, requiring multiple tools, high setup times, and messy maintenance, with potential for unpleasant odors and hand contamination.
Innovation Solution
A cleaning device with a rotatable base and a replacement head featuring a suction inlet and scrubbing pad, allowing for easy attachment and detachment with minimal effort and mess, and including a hinge for pivotable handle assembly to facilitate efficient cleaning of dry and wet debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate tools (vacuum, dry mop, wet mop) are used to handle mixed media debris, then cleaning capability is improved, but setup time and device complexity increase
Solution Approach 1:
The patent combines vacuum, dry mop, and wet mop functionalities into a single integrated cleaning device. The base unit houses a motor that can drive different attachments including a vacuum head with HEPA filter, a dry mop head with rotating pads, and a wet mop head with water reservoir, allowing users to handle all types of debris with one device rather than switching between multiple separate tools
Solution Approach 2:
The cleaning device is designed as a universal system where a single base unit can accommodate multiple types of heads and attachments. The base includes a standardized interface that accepts vacuum heads, dry mop heads, and wet mop heads, enabling one device to perform multiple cleaning functions across different floor types and debris conditions
2Adaptability or versatility
If combination cleaning tools are used to handle both dry and wet media, then versatility is improved, but after-use maintenance becomes more complex and time-consuming
Solution Approach 1:
The cleaning device is divided into separable components including a removable base unit, detachable heads, and interchangeable attachments. The vacuum head, dry mop head, and wet mop head can all be detached from the base for independent cleaning and maintenance. The HEPA filter is accessible and removable for regular maintenance, and the water reservoir in the wet mop head can be easily emptied and cleaned separately from the main device
Solution Approach 2:
The patent incorporates disposable or easily replaceable components such as the mop pads and filters. The dry mop pads and wet mop pads are designed to be inexpensive and replaceable, allowing users to simply swap out worn pads rather than performing complex maintenance procedures. This reduces the skill and time required for maintenance while maintaining cleaning effectiveness
3Device complexity
If traditional broom and mop combination is used, then simplicity is maintained, but cleaning effectiveness on mixed media debris is insufficient
Solution Approach 1:
The cleaning device incorporates dynamic elements including a motor-driven rotating mechanism that can switch between different head types during operation. The base unit contains a motor that can rotate the attachment head, allowing transitions between vacuuming, dry mopping, and wet mopping modes. This dynamic capability enables the device to adapt to different debris types during a single cleaning session, significantly improving cleaning effectiveness compared to static traditional tools

AI summary
A cleaning device including a handle assembly including a proximal end and a distal end, a base having a front edge and a rear edge, a hinge attached between the distal end of the handle assembly and the base, the hinge defining a first axis between the hinge and the base, a replacement head removably attachable to the base, the replacement head including a suction inlet and a pad defining a lower surface, wherein the first axis is positioned to maintain contact between the lower surface and a floor and avoid skipping.
