Turbine-Driven Floor Cleaning Head With Separate Suction Chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices for wet floor surfaces require a mains connection and are not suitable for use as additional devices with canister vacuum cleaners, and they inefficiently dispense and absorb cleaning liquids on smooth surfaces.
Innovation Solution
A cleaning device with a turbine-driven cleaning roller and a separate suction chamber that uses a slit-shaped suction opening to effectively absorb cleaning fluid without mixing it with air flow, allowing the air flow to drive the turbine and ensuring complete liquid absorption on the floor surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the suction chamber is connected to the roller chamber, then the structure is simpler, but cleaning fluid is discharged as droplets with the air flow
Solution Approach 1:
The suction chamber is segmented into two distinct parts: a first suction chamber for air flow and a second suction chamber for liquid/dirt removal. This segmentation prevents mixing of air flow with cleaning fluid, eliminating droplet discharge while maintaining structural efficiency.
2Adaptability or versatility
If the cleaning device is designed for textile floor coverings, then it achieves good cleaning results on carpets, but it is not suitable for smooth floor surfaces
Solution Approach 1:
The cleaning device is designed with universal applicability for both textile floor coverings and smooth floor surfaces. The adjustable roller pressure and versatile suction system enable effective cleaning across different floor types, making the device adaptable to multiple cleaning scenarios.
3Loss of substance
If the suction opening is narrow slit-shaped, then liquid intake during rearward movement is reduced, but dirt particle removal efficiency decreases
Solution Approach 1:
The suction function is segmented into two separate openings: a first suction opening for air and dirt particle removal, and a second suction opening for liquid intake. This segmentation allows the narrow slit-shaped first opening to effectively remove dirt while the second opening handles liquid, preventing fluid loss.
4Power
If the cleaning device requires a mains connection, then it provides sufficient power for cleaning, but it cannot be used as an additional device with canister vacuum cleaners
Solution Approach 1:
The cleaning device utilizes the air flow from connected vacuum cleaners to drive its turbine, eliminating the need for a separate mains connection. This self-service approach allows the device to operate using the vacuum cleaner's power source, enabling compatibility and versatile use.
