Handheld extraction cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld extraction cleaners often lack a balanced weight distribution and efficient modular design, making them cumbersome to use and maintain.
Innovation Solution
A handheld extraction cleaner with a unitary body featuring a supply tank in front of the suction motor and a recovery tank centered below the handle, along with a modular fluid supply assembly that can be easily removed, providing balanced weight and improved usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the supply tank and fluid distributor are separate components, then maintenance and refilling are easier, but the device structure becomes more complex and requires more assembly steps
Solution Approach 1:
The device is divided into modular components: a removable supply tank and a fluid distributor that can be separated. The supply tank includes a tank body with a fluid outlet that connects to the fluid distributor through a quick-connect mechanism, allowing easy separation and reattachment without complex assembly steps
Solution Approach 2:
The supply tank and fluid distributor are combined into an integrated assembly where the fluid outlet of the tank body directly interfaces with the fluid distributor. This merging allows the components to function as a unified system while maintaining the ability to separate them for maintenance, resolving the contradiction between ease of repair and device complexity
2Ease of operation
If the recovery tank is positioned below the handle for balanced weight distribution, then user comfort improves, but the internal space arrangement becomes more constrained
Solution Approach 1:
The recovery tank is positioned in the vertical dimension below the handle rather than horizontally, which balances the weight distribution for user comfort while utilizing the vertical space within the housing. This dimensional repositioning allows the tank to be centered below the handle grip without compromising horizontal space for other components
3Ease of operation
If the supply tank is positioned in front of the suction motor, then the weight distribution is optimized, but the airflow path becomes more complex
Solution Approach 1:
The housing is designed with a localized opening in the front wall that allows the supply tank to be positioned in front of the suction motor. This localized structural modification enables optimal weight distribution while the airflow path is designed to flow around the tank position without requiring complex routing, maintaining simplicity in the airflow design
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 design enhances user comfort and operational efficiency by distributing weight evenly and allowing for easy maintenance and refilling of the cleaning solution, improving the overall cleaning process.
Implementation Method 1
a vacuum motor that powers an impeller to create low pressure on one side of the impeller and higher pressure on the other side thereof
