Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning apparatuses require separate machines for vacuuming and extracting cleaning solutions, as they are not designed to handle large particulate matter or liquids effectively, leading to inefficiencies and increased storage needs.
Innovation Solution
A surface cleaning apparatus that operates in both vacuum and extractor modes, featuring a liquid distribution system, momentum separators, and cyclone separators to handle both dry and wet cleaning tasks, allowing for a single device to vacuum, apply, and extract cleaning solutions, with energy-efficient design and reduced footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate vacuum cleaner and extractor machines are used, then each machine can be optimized for its specific function, but the user must store and manage two separate machines
Solution Approach 1:
The patent combines a vacuum cleaner and extractor into a single integrated apparatus. The housing contains both a cyclone separator for dry debris and a liquid separator for wet debris, along with a common suction motor and handle, allowing one machine to perform both vacuuming and carpet extraction functions
Solution Approach 2:
The apparatus is designed with universal functionality to handle both dry particulate matter and liquid-soil mixtures. The separation system can operate in two modes: vacuum mode for dry debris and extractor mode for wet debris, making a single device suitable for multiple cleaning scenarios
2Device complexity
If a single apparatus handles both vacuum and extract functions, then storage requirements are reduced, but the apparatus must effectively handle both large particulate matter and liquids
Solution Approach 1:
The separation system is segmented into two distinct stages: a cyclone separator for removing large particulate matter and a liquid separator for removing liquid and fine debris. This segmentation allows each component to be optimized for its specific function while working together in sequence to handle both dry and wet debris effectively
Solution Approach 2:
The patent introduces a vertical dimension to the separation process by stacking the cyclone separator above the liquid separator. This vertical arrangement allows the apparatus to handle both types of debris in a compact footprint, with the cyclone processing dry debris first and the liquid separator handling wet debris below
3Area of stationary object
If the liquid treatment stage is positioned at a higher elevation, then the overall footprint may be reduced, but substantially more energy is required to draw liquid upward
Solution Approach 1:
The patent utilizes the vertical dimension by positioning the cyclone separator above the liquid separator, accepting the energy cost of drawing liquid upward in exchange for achieving a compact footprint. The suction motor generates sufficient suction to overcome gravity and draw liquid from the lower liquid separator through the upper cyclone separator to the exhaust

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 surfaces with a single apparatus, reducing energy consumption and storage requirements by effectively handling both dry and wet debris and liquids, while maintaining a compact design.
Implementation Method 1
The first treatment stage may be designed to remove liquid from an air stream (e.g., a momentum separator)
Implementation Method 2
The second treatment stage may be designed to remove solid particulate matter from the air stream (e.g., one or more cyclones in parallel)
