Portable Extraction Cleaner Diverter Valve for Quiet Fluid Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional carpet extractors lack a seamless integration of fluid delivery and recovery systems with noise reduction and ease of maintenance, particularly in portable designs, which affects their efficiency and user experience.
Innovation Solution
A portable extractor with a housing featuring a suction source, interconnected suction hose, recovery tank, fluid delivery system, and a diverter valve mechanism that opens communication between the recovery tank and suction nozzle when mounted to a base, allowing for efficient fluid management and noise reduction through directed airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the portable extractor is designed with integrated fluid delivery and recovery systems, then cleaning efficiency is improved, but device complexity increases
Solution Approach 1:
The patent combines the fluid delivery system and fluid recovery system into a single integrated portable extractor unit. The fluid delivery system includes a fluid supply tank, fluid distributor, and fluid supply conduit, while the fluid recovery system includes a recovery tank, nozzle, and working air conduit. These systems are merged into one device with a common housing and coordinated operation, allowing simultaneous or sequential fluid application and recovery during the cleaning process, thereby improving cleaning efficiency while managing system complexity through unified design.
2Productivity
If the suction source is directed toward the user during operation, then fluid recovery is improved, but noise exposure to the user increases
Solution Approach 1:
The patent introduces a diverter valve as an intermediary component that controls the direction of the suction source. The diverter valve can redirect the airflow path, allowing the suction source to be oriented away from the user during operation. This intermediary mechanism enables the system to maintain effective fluid recovery while reducing direct noise exposure to the user by altering the airflow direction without compromising suction performance.
3Ease of operation
If the extractor is designed as a portable unit with all components integrated, then ease of operation is improved, but ease of repair deteriorates
Solution Approach 1:
The patent divides the portable extractor into distinct functional modules or segments that can be independently accessed for maintenance. The fluid delivery system and fluid recovery system are structured as separate but integrated components within the housing, allowing technicians to access specific subsystems for repair or replacement without disassembling the entire unit. This segmentation maintains portability while facilitating easier maintenance and repair operations.
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
Enhances cleaning efficiency by ensuring effective fluid recovery and noise reduction, while the diverter valve simplifies maintenance by allowing easy inspection and clearing of debris, improving user experience and operational efficiency.
Implementation Method 1
a source of suction in fluid communication with the working air conduit to draw the cleaning fluid from the surface to be cleaned and through the nozzle and the working air conduit to the recovery tank
