Solution Overview
Problem
Existing surface cleaning apparatuses require separate machines for vacuuming and extracting cleaning solutions, as they are not designed to handle both dry and wet cleaning modes efficiently, 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, a momentum separator for liquids, and a cyclone separator for solids, allowing it to vacuum debris before applying cleaning solutions and then extract them, with energy-efficient design and reduced footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single apparatus is designed to operate in both vacuum and extractor modes, then versatility and storage efficiency improve, but device complexity increases
Solution Approach 1:
The apparatus is designed with a universal structure that can operate in multiple cleaning modes (vacuum and extractor) by incorporating both a cyclone separator for solids and a momentum separator for liquids, allowing a single device to replace multiple specialized cleaners
Solution Approach 2:
The separation system is divided into distinct functional segments: a cyclone separator stage for solid particulate matter and a momentum separator stage for liquid, with each stage optimized for its specific separation task while integrating into a unified apparatus
2Use of energy by moving object
If the liquid treatment stage is positioned below the solid particulate matter treatment stage, then energy consumption is reduced, but the apparatus height increases
Solution Approach 1:
The separators are arranged in a vertical stacking configuration along the height dimension, allowing the liquid momentum separator to be positioned below the solid cyclone separator, optimizing energy consumption by treating liquid at a lower elevation while maintaining a compact footprint
3Area of stationary object
If a single apparatus handles both liquids and solids, then storage requirements are reduced, but separation system complexity increases
Solution Approach 1:
The apparatus merges the solid separation system (cyclone separator) and liquid separation system (momentum separator) into a single integrated unit with unified housing, control, and collection chambers, reducing the need for separate storage spaces while maintaining distinct separation functions
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 a single apparatus for both dry and wet cleaning, reducing energy consumption and storage requirements by efficiently separating liquids and solids, and allowing for concurrent emptying of liquid and solid collection chambers.
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)
