Bare Floor Cleaner Handle-Linked Diverter for Wet/Dry Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for cleaning bare floors require multiple tools and involve physical exertion, inefficiencies in solution application and pickup, and can damage surfaces, with existing multi-functional cleaners often being complex and difficult to operate.
Innovation Solution
A wet/dry bare floor cleaner with a pivotally connected handle, a recovery system featuring dual suction nozzles and a diverter actuated by handle movement, a motor/fan assembly for airflow, and an agitator for vertical movement to selectively switch between dry and wet cleaning modes, allowing for efficient debris and solution pickup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate cleaning tools (broom, dustpan, mop) are used for bare floor cleaning, then cleaning functionality is comprehensive, but device complexity and ease of operation deteriorate due to needing multiple tools and steps
Solution Approach 1:
The patent combines multiple cleaning functions (dry pickup, wet pickup, solution application, and agitation) into a single integrated cleaner unit. The device merges the capabilities of a broom, dustpan, mop, and solution dispenser into one machine with a unified base containing all necessary components
Solution Approach 2:
The cleaner is designed as a universal device that can perform multiple cleaning tasks through different modes. The base unit serves multiple functions: dry debris pickup via dry nozzle, wet solution pickup via wet nozzle, solution application via spray system, and surface agitation via brush or pad, making it adaptable to various cleaning needs
2Adaptability or versatility
If a diverter system with multiple nozzles is added to enable wet and dry pickup, then adaptability improves, but device complexity and ease of operation worsen due to additional controls
Solution Approach 1:
The diverter system is designed to be dynamically controlled by the handle position rather than requiring separate controls. As the user moves the handle between different angular positions, the diverter automatically redirects airflow between the dry nozzle and wet nozzle, making the switching action intuitive and effortless
Solution Approach 2:
The handle serves as an intermediary control element that mediates between the user's intent and the diverter's action. By linking handle position to diverter position, the system translates a simple user motion into the appropriate cleaning mode without requiring direct manipulation of the diverter mechanism
3Reliability
If an agitator with vertical movement is included for solution application, then cleaning effectiveness improves, but device complexity and weight increase
Solution Approach 1:
The agitator is designed with vertical movement capability that can be dynamically positioned between contact and non-contact states with the floor surface. This allows the agitator to engage with the surface when cleaning effectiveness is needed and disengage when not required, providing adaptable cleaning action
Solution Approach 2:
The agitator serves multiple functions: it agitates the floor surface to loosen dirt, applies cleaning solution through its structure, and can be positioned to contact or hover above the surface. This multi-functionality reduces the need for separate agitation and solution application components
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 and convenient switching between dry and wet cleaning modes, reducing physical exertion and tool complexity, while effectively removing debris and solution from bare floors without damaging surfaces.
Implementation Method 1
a motor/fan assembly mounted to one of the handle and the base and adapted to create a working air flow in the working air conduit from at least one of the dry suction nozzle and the wet nozzle and to the recovery tank
Implementation Method 2
a diverter mounted in the working air conduit and movable between a dry suction position and a wet suction position for selectively at least partially blocking working air flow from the wet suction nozzle and the dry suction nozzle, respectively, to the recovery tank

AI summary
A bare floor cleaner for wet and dry bare floor surfaces comprises a base with wet and dry suction nozzles and a handle pivotally connected to the base. A diverter mounted in the working air conduit between each of the dry suction nozzle and the wet suction nozzle to a recovery tank is movable by movement of the handle between a dry suction position and a wet suction position for selectively at least partially blocking working air flow from the wet suction nozzle and the dry suction nozzle, respectively, to the recovery tank.
