Solution Overview
Problem
Existing cleaning systems are inefficient in washing and drying long cleaning fringes due to the need for significant user effort and the risk of the fringes touching the bucket wall during spin-drying, leading to slowed rotation and inadequate drying.
Innovation Solution
A cleaning system with a disk-shaped mop head and a rotationally symmetrical basket that allows for a ratio of basket width to mop head diameter ≥ 1.5, enabling thorough washing and efficient drying without the fringes touching the bucket wall, using a basket that can be moved up and down for washing and rotated for drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the basket width is increased to accommodate long cleaning fringes without touching the bucket wall, then the drying effectiveness is improved, but the device dimensions become excessively large and impractical to handle
Solution Approach 1:
The system separates the washing and spin-drying functions into distinct operational phases. During washing, the basket is positioned at the bottom to immerse fringes in water. During spin-drying, the basket is elevated above the water level, allowing fringes to be thrown outward against the basket wall without contacting the bucket wall, even with long fringes.
Solution Approach 2:
The solution moves the spin-drying operation from a horizontal plane concern (bucket diameter) to a vertical plane solution (basket elevation). By lifting the basket above the water level, the system creates vertical clearance that prevents fringe-bucket wall contact during rotation, eliminating the need for excessive horizontal space.
2Device complexity
If the cleaning fringes are pressed between the supporting body and the basket bottom for spin-drying, then the structure is compact, but the fringes become pressed together and rotation is slowed down
Solution Approach 1:
Instead of pressing fringes against the basket bottom (axial direction), the system inverts the approach by allowing fringes to be thrown outward against the basket's side wall (radial direction) during rotation. This inversion enables effective spin-drying without axial compression that would slow rotation.
Solution Approach 2:
The system transitions from a static pressing arrangement to a dynamic spin-drying arrangement. The basket rotates to throw fringes outward against the wall, using centrifugal force for drying rather than mechanical pressing, thereby maintaining high rotation speed.
3Extent of automation
If a foot pedal actuating device is used for spin-drying, then the operation is automated, but the device complexity increases
Solution Approach 1:
The system uses the user's own body weight and natural pressing motion on the mop head handle to drive the spin-drying operation. The user presses the mop head downward, and this force is directly transmitted to rotate the basket, eliminating the need for separate foot pedals or complex actuating mechanisms.
