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, allowing for a fluid-tight and air-tight connection to spray cleaning fluid directly onto the surface while trapping the spray between the device and the surface, preventing airborne contamination and improving ergonomics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If cleaning fluid is sprayed using prior art devices, then cleaning function is provided, but airborne contamination occurs and ergonomics are poor
Solution Approach 1:
The patent introduces a fluid delivery system with a reservoir, pump, and spray nozzle as an intermediary between the cleaning fluid source and the surface being cleaned. This mediator controls the spray pattern and direction, preventing airborne contamination while maintaining ergonomic operation. The system channels fluid through a controlled path rather than allowing uncontrolled spraying.
Solution Approach 2:
The patent changes the parameters of fluid delivery by using a pump to control spray pressure and a nozzle to control spray pattern. This transforms the fluid delivery from uncontrolled spraying to a controlled stream that reaches the surface without creating airborne contamination, while the ergonomic design maintains ease of operation.
2Productivity
If spray nozzle is positioned to spray cleaning fluid onto surface, then cleaning effectiveness is improved, but fluid leakage and hydraulic resistance increase
Solution Approach 1:
The patent uses a pump and nozzle system as intermediaries to control fluid delivery. The pump ensures positive displacement and control of fluid flow, preventing leakage, while the nozzle precisely directs the spray to the surface for effective cleaning. This intermediary system maintains reliability while improving productivity.
Solution Approach 2:
The patent employs hydraulic principles through the use of a pump to generate controlled fluid pressure and a nozzle to direct the fluid stream. This hydraulic system ensures reliable fluid delivery without leakage while maintaining cleaning effectiveness by precisely controlling the spray parameters.
3Ease of operation
If pump and battery system is added to cleaning device, then spray control and ergonomics are improved, but device complexity increases
Solution Approach 1:
The patent integrates a battery-powered pump system that serves multiple functions: it provides spray control, powers the cleaning device operations, and enables ergonomic handheld operation. This multi-functional design improves spray control and ease of operation while minimizing the increase in device complexity by consolidating functions into a single integrated system.
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 prevents airborne cleaning fluid from reaching the user, enhances ease of use with improved ergonomics, and minimizes fluid leakage and hydraulic resistance, making it more efficient for cleaning hard surfaces.
Implementation Method 1
The spray nozzle is in fluid communication with an outlet of the pump. 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.
