Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extraction cleaners lack an efficient mechanism for distributing cleaning liquid and recovering dirt and liquid from surfaces, often requiring multiple tools and complex hose connections, which can be cumbersome and inefficient.
Innovation Solution
A cleaning tool with a nozzle portion connected to an elongated handle, featuring a suction nozzle for dirt and liquid recovery, an internal conduit for transporting recovered materials, a spray nozzle for distributing cleaning liquid, and a valve mechanism to control fluid flow, integrated with a supply tube and hose connection for seamless operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate tools are used for cleaning operations, then functional versatility is improved, but device complexity and ease of operation deteriorate due to multiple hose connections and tool changes
Solution Approach 1:
The patent combines multiple cleaning functions (spray nozzle for liquid distribution, suction nozzle for dirt and liquid recovery, and rinse function) into a single integrated cleaning tool. The tool body houses both spray and suction nozzles, with a valve mechanism that controls fluid flow to enable different cleaning modes without requiring tool changes or multiple hose connections.
Solution Approach 2:
The cleaning tool is designed as a multi-functional device that can perform spray cleaning, suction recovery, and rinse operations. The valve mechanism allows the user to switch between different functions (spray, suction, rinse) using a single tool, eliminating the need for multiple specialized tools and simplifying operation.
2Adaptability or versatility
If multiple separate tools are used for cleaning operations, then functional versatility is improved, but ease of operation deteriorates due to cumbersome multiple hose connections
Solution Approach 1:
The patent integrates spray and suction functions into one tool with a unified hose connection system. The single tool eliminates the need to connect and disconnect multiple hoses when switching between cleaning functions, making operation simpler and more convenient while maintaining functional versatility.
Solution Approach 2:
The multi-functional design allows the user to perform spray, suction, and rinse operations with a single tool connection. The valve mechanism enables function switching without requiring physical reconnection of hoses, significantly improving ease of operation while preserving adaptability.
3Ease of operation
If cleaning functions are integrated into a single tool, then ease of operation is improved, but manufacturing complexity increases due to internal conduit and valve mechanism integration
Solution Approach 1:
The patent employs a nested structure where the supply tube is positioned inside the internal conduit. This nesting arrangement allows multiple fluid pathways to be integrated within the same tool body without excessive complexity. The valve mechanism is integrated into the handle portion, with components arranged in a compact, nested configuration that simplifies assembly while maintaining multi-functionality.

Function Achieved in This Case
The tool enables efficient distribution of cleaning liquid and recovery of dirt and liquid, enhancing cleaning efficiency and simplifying the cleaning process by integrating essential functions into a single, user-friendly device.
Implementation Method 1
The extraction cleaner then draws the cleaning fluid along with dirt from the surface through a suction nozzle
Implementation Method 2
a spray nozzle configured to distribute cleaning liquid forward of the nozzle cover

AI summary
A cleaning tool for an extraction cleaner includes a tool body including a nozzle portion connected to an elongated handle portion and a nozzle cover removably mounted to the nozzle portion forming a suction nozzle therebetween. The suction nozzle is configured to extract recovered liquid and dirt. The cleaning tool also includes an internal conduit in fluid communication with the suction nozzle configured to transport recovered liquid and dirt extracted by the suction nozzle. The internal conduit extending longitudinally within the handle portion between opposite ends of the handle portion. The cleaning tool further includes a spray nozzle configured to distribute cleaning liquid forward of the nozzle cover and a supply tube configured to carry cleaning liquid to the spray nozzle. The spray nozzle passes through the suction nozzle or the inlet conduit.
