Bare Floor Cleaner Mode Selector for Wet Scrub and Pickup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bare floor cleaning appliances lack the ability to efficiently switch between multiple cleaning modes using a single mode selector and do not have an accessory hose and telescoping wand for cleaning hard-to-reach areas such as behind toilets and grout between tiles.
Innovation Solution
A bare floor cleaning appliance with a rotating knob for switching between three cleaning modes, an accessory hose and telescoping wand connected through a port for suction and cleaning solution delivery, and a caddy for storing accessories and supplies, allowing for extended cleaning capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple separate controls are used for each cleaning mode function, then each function can be controlled independently, but the device complexity increases and ease of operation decreases
Solution Approach 1:
The patent combines multiple control functions (mode selection, suction nozzle height adjustment, and brush block height adjustment) into a single mode selector mechanism. When the mode selector is rotated to different positions, it simultaneously controls the suction nozzle height and brush block height, eliminating the need for separate controls and simplifying the user interface.
Solution Approach 2:
The mode selector serves multiple functions: it selects the cleaning mode, adjusts the suction nozzle height, and adjusts the brush block height. This multi-functional control mechanism reduces the number of separate controls needed and simplifies the overall device operation.
2Adaptability or versatility
If the cleaning appliance is designed for standard reach only, then the structure remains simple, but it cannot clean hard-to-reach areas
Solution Approach 1:
The cleaning system is divided into a main body and a separate accessory hose assembly. The accessory hose with telescoping wand can be detached and used independently to reach areas behind toilets, in shower stalls, and other hard-to-reach locations, while the main body remains relatively simple in structure.
Solution Approach 2:
The accessory hose acts as an intermediary component that extends the cleaning capability of the appliance. It connects the main body's suction and solution delivery systems to remote locations, enabling cleaning in areas that would otherwise be inaccessible without significantly complicating the main device structure.
3Ease of operation
If accessories and supplies are stored separately, then organization is simple, but accessibility and convenience decrease
Solution Approach 1:
The caddy is integrated with the cleaning appliance, combining accessory storage and supply storage into a unified structure attached to the main body. This allows all necessary items (accessory hose, telescoping wand, tools, and cleaning supplies) to be stored together and accessed conveniently during cleaning operations.
Solution Approach 2:
The caddy is pre-configured with compartments and holders for organizing accessories and supplies before use. This preliminary organization ensures that all necessary items are readily accessible and properly positioned for efficient cleaning operations.
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 various bare surfaces by allowing mode selection, extended reach with the accessory hose and wand, and convenient storage of tools and supplies, enhancing cleaning versatility and accessibility.
Implementation Method 1
The air turbine pump is utilized in the accessory hose to pressurize the cleaning solution
Implementation Method 2
A gravity fed manifold located above the brush block delivers the cleaning solution to the floor surface

AI summary
A floor care appliance is provided for cleaning bare surfaces such as tile, marble, linoleum and wood. The floor care appliance is comprised of a base portion having a suction nozzle and a brush block having a plurality of vertical axis rotary agitators for cleaning bare floors. The rotary agitators are driven by an independent motor for agitating the floor surface. With the addition of an accessory hose and tools, the cleaning utility can be expanded to areas wherein the suction nozzle cannot normally reach such as behind the toilet, shower walls, and the grout between tile. While used in the capacity for cleaning bare floors, the floor care appliance can be moved between three modes by a rotating a member located on the upper housing. The first mode is dry mode, the second mode is wet scrub mode and the third mode is wet pickup mode. The accessory tools are stored in an accessory caddy that is placed freestanding over the suction nozzle and in front of the housing.
