Water-spraying mop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional water-spraying mops experience instability in water spraying due to squeezable pipelines, leading to obstructed flow and reduced stability during use.
Innovation Solution
A water-spraying mop design featuring a universal joint connecting the mop head and rod, a water tank at the mop head, and a water pump in the rod, with a dynamic mechanism and single-direction positioning structures to ensure stable and efficient liquid flow and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mop rod and mop head are rotated and bent during use, then the mop can adapt to different cleaning angles and surfaces, but the water-spraying pipeline becomes easily squeezable and obstructed
Solution Approach 1:
The patent applies a dynamic mechanism consisting of an upper inner rod and lower inner rod that can move relative to each other within the mop rod. This dynamic structure allows the pipeline to accommodate rotations and bends of the mop rod and mop head without being squeezed or obstructed, maintaining water spraying stability while enabling cleaning angle adaptability.
Solution Approach 2:
The patent implements a nested structure where the upper inner rod is inserted into the upper rod body, and the lower inner rod is inserted into the lower rod body. The inner rods are nested within the mop rod structure, allowing them to move independently while being protected by the outer structure, thus preventing pipeline obstruction during mop manipulation.
2Device complexity
If a traditional water-spraying pipeline structure is used, then the structure is simple, but the pipeline becomes obstructed leading to low spraying stability
Solution Approach 1:
The patent introduces a dynamic mechanism with movable inner rods that can slide within the mop rod structure. This dynamic design maintains relative structural simplicity while ensuring the pipeline remains unobstructed during use, thereby achieving both simplicity and spraying stability.
Solution Approach 2:
The patent segments the mop rod into upper and lower rod bodies with corresponding inner rods. This segmentation allows independent movement of each segment, preventing pipeline obstruction while maintaining an overall simple structure that is easy to manufacture and assemble.
