Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices for hard surfaces are less than optimal, as they inefficiently spray cleaning fluids, leading to airborne contamination and poor ergonomics during use.
Innovation Solution
A cleaning device with a housing, cleaning head, container, and spray nozzle system that includes a pump and battery for efficient fluid delivery, with the spray nozzle positioned to trap fluid between the device and the surface, preventing airborne contamination and improving ergonomics through adjustable design and interchangeable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If cleaning fluid is sprayed onto surfaces using prior art devices, then cleaning is achieved, but airborne contamination occurs and ergonomics are poor
Solution Approach 1:
The patent introduces a cleaning fluid delivery system with a reservoir, pump, and spray mechanism as an intermediary between the user and the surface. This allows controlled application of cleaning fluid through registration openings in the cleaning head, preventing uncontrolled spraying and airborne contamination while maintaining ergonomic operation through the integrated design
Solution Approach 2:
The patent extracts the harmful spraying function from traditional cleaning devices and replaces it with a controlled fluid delivery system. The cleaning fluid is delivered through registered openings rather than being sprayed into the air, removing the airborne contamination problem while preserving the cleaning function
2Object-affected harmful factors
If spray nozzle is positioned to trap fluid between device and surface, then airborne contamination is prevented, but device complexity increases
Solution Approach 1:
The patent merges the spray nozzle positioning with the cleaning head structure, integrating the fluid delivery system into the existing cleaning device framework. The registration openings are incorporated into the cleaning head design, and the spray nozzle is positioned to work in conjunction with the cleaning element, combining multiple functions without significantly increasing overall device complexity
Solution Approach 2:
The patent implements a nested structure where the spray nozzle is positioned within or adjacent to the cleaning head, and the fluid delivery system is integrated within the housing. The registration openings are nested within the cleaning head structure, creating a compact arrangement that prevents airborne contamination without adding significant complexity
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 device effectively contains cleaning fluid spray, preventing airborne contamination and enhancing user convenience and efficiency during cleaning tasks on various surfaces.
Implementation Method 1
a pump and battery in the housing selectively spray a cleaning fluid from the container onto the surface being cleaned
Implementation Method 2
The spray nozzle is positioned on the cleaning head so as to spray the cleaning fluid from the container through the first spray opening onto a surface being cleaned

AI summary
A cleaning device is provided that includes a cleaning element, a cleaning head, a housing, an electric pump, a battery, a container of cleaning fluid, an activation button, and a spray nozzle. The cleaning element and the cleaning head have spray openings that are in registration with one another. The container forms a fluid and air tight connection with the pump. The activation button places the pump and the battery in electrical communication. The spray nozzle forms a fluid tight and air tight connection with the pump so that the pump is configured to spray fluid from the container through the first and second spray openings onto a surface to be cleaned. The cleaning head, the cleaning element, and the spray nozzle define a cavity that traps spray from the spray nozzle between the cleaning device and the surface to be cleaned.
