Floor Head Stand Structure for Roller Lift and Edge Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning machines face challenges in achieving optimized cleaning results with a compact design while avoiding damage to substrates and ensuring effective drying of cleaning rollers, particularly in tight spaces and near edges.
Innovation Solution
The design incorporates a tank device with a continuous recess to allow the cleaning roller to be lifted off the base in the parking position, preventing contact with the substrate and enabling better drying, and a compact stand device that allows the machine to be used in hand-held or self-steering configurations without compromising external dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cleaning roller is kept in contact with the base during parking, then the machine structure remains simple, but the cleaning roller develops flat spots and the substrate may be damaged
Solution Approach 1:
The support foot is extracted as a separate movable component from the main machine body, allowing it to be deployed independently during parking to lift the cleaning roller off the base, preventing flat spots while keeping the main structure simple
Solution Approach 2:
The support foot device transitions from a static to a dynamic configuration, moving between retracted and extended positions based on whether the machine is in operation or parking mode, enabling the cleaning roller to be lifted during parking without permanent structural changes
2Adaptability or versatility
If the cleaning roller extends to the transverse sides for edge cleaning, then cleaning coverage is improved, but the external dimensions increase
Solution Approach 1:
The support foot extends in the vertical dimension through the tank device rather than increasing the horizontal width, allowing the cleaning roller to reach the transverse sides for edge cleaning while maintaining a compact floor head width for clearance under furniture
3Reliability
If the tank device is designed with high walls for fluid containment, then fluid retention is improved, but clearance under obstacles is reduced
Solution Approach 1:
The tank device is segmented with a through recess that divides the fluid containment space, allowing the support foot to pass through while maintaining adequate fluid retention volume in the separated chambers
Solution Approach 2:
The tank device utilizes a flexible or thin-walled structure with the through recess that can accommodate the support foot passage without significantly compromising fluid containment capability, reducing the overall height of the base plate
4Ease of operation
If the support foot extends through the tank device, then cleaning roller drying is improved, but the tank device structure becomes more complex
Solution Approach 1:
The through recess in the tank device serves multiple functions: it allows the support foot to pass through for lifting the cleaning roller during parking, provides a passage for air circulation to enhance drying, and maintains structural integrity of the tank device without requiring additional separate components
