Solution Overview

Problem

Existing mop systems lack an efficient method for dewatering the mop head after cleaning, which is essential for effective surface cleaning.

Innovation Solution

A spin mop system with a rotatable mop head that engages a wringer basket on a bucket assembly, allowing the mop head to spin and the wringer basket to rotate, utilizing centrifugal force to remove excess water from the mop head.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a traditional mop is used to clean surfaces, then the mop head becomes dirty and requires dewatering, but the existing mop systems lack an efficient dewatering method

Engineering Contradiction:

Improvedewatering efficiencyVSAvoiddewatering process simplicity

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent employs rotational motion of the mop head within the wringer basket to create centrifugal force, which acts as a form of mechanical vibration/movement to extract water from the mop head. The rotating motion agitates the mop head and forces water out through the basket walls, significantly improving dewatering efficiency compared to traditional static wringing methods.

Inventive Principle:

Principle #18Mechanical vibration

Solution Approach 2:

The wringer basket is designed with holes that allow water to pass through during rotation, utilizing hydraulic principles. The centrifugal force generated during rotation creates pressure that forces water through the basket walls and into the bucket, providing an efficient hydraulic dewatering mechanism.

Inventive Principle:

Principle #29Pneumatics and hydraulics

2Productivity

If the mop head is rotated to dewater it, then water is removed from the mop head, but the system requires coordination between mop head rotation and wringer basket rotation

Engineering Contradiction:

Improvewater removal effectivenessVSAvoidmechanism coordination

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the rotation of the mop head and the wringer basket into a single coordinated motion system. By connecting the mop head rotation to the basket rotation through the spiral member and swivel member mechanism, both components rotate simultaneously in the same direction, eliminating the need for separate control mechanisms and reducing overall system complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system is designed so that the user's single action of rotating the mop head automatically drives the wringer basket rotation through the spiral member engagement. The basket serves itself by rotating in response to the mop head rotation, eliminating the need for additional actuators or control mechanisms.

Inventive Principle:

Principle #25Self-service

3Productivity

If the wringer basket rotates to remove water, then excess water is forced out of the mop head, but water may splash outside the bucket

Engineering Contradiction:

Improvedewatering speedVSAvoidwater splashing

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the potentially harmful effect of water splashing during rotation into a beneficial contained flow. The splash guard is designed to intercept water that would otherwise splash outward and redirect it back into the bucket. The centrifugal force that causes splashing is harnessed to direct water along the splash guard surface and into the bucket, transforming a harmful effect into a controlled water flow path.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

A spin mop and bucket system to assist in dewatering a mop is disclosed. The spin mop may have a handle assembly slidably connected with a spiral member, and a mop head that is attached to the spiral member. When the handle assembly moves along the spiral member, the spiral member rotates causing the mop head to rotate. The mop head may articulate relative to the handle assembly and may be pivotally connected to the spiral member and also pivotally connected to a swivel member located between the spiral member and a mop head base. The mop head may be received in a wringer basket of a bucket assembly, such that when the mop head spins, the wringer basket spins to expel any excess fluid from the mop head.
