Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mop wringers are complex, prone to breakage, and often fail to completely remove liquid from mop strings, with high manufacturing and assembly costs and unsatisfactory wringing results.
Innovation Solution
A simple, durable mop wringer device with no moving parts, featuring a rod that projects from the bucket wall to engage mop strings, allowing effective liquid removal through twisting, and includes design features like grooves and a friction-enhancing base for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wringers are used, then liquid can be removed from mop strings, but the device complexity increases and manufacturing costs rise
Solution Approach 1:
The patent extracts the essential wringing function from complex traditional wringers and implements it through a simple rod that projects from the bucket wall. This rod engages the mop strings directly, eliminating the need for complicated mechanisms while maintaining effective liquid removal capability.
Solution Approach 2:
The wringer rod is designed to engage and hold the mop strings automatically through its geometric shape and positioning. The strings themselves provide the gripping mechanism by wrapping around the rod, eliminating the need for additional clamping or holding mechanisms.
2Reliability
If traditional wringers with moving parts are used, then wringing function is achieved, but durability decreases due to breakage and sun damage
Solution Approach 1:
The patent removes all moving parts from the wringing mechanism, retaining only the essential stationary rod that provides the wringing surface. This eliminates components susceptible to breakage and sun damage while preserving the core wringing function.
Solution Approach 2:
The wringer rod is designed as a simple, replaceable component that can be easily manufactured and installed. If damaged, it can be quickly replaced without affecting other parts of the system, reducing overall system vulnerability.
3Reliability
If complex wringers are used, then wringing capability is provided, but manufacturing and assembly costs increase
Solution Approach 1:
The patent extracts only the essential wringing element (the rod) from complex traditional wringers, eliminating unnecessary components that increase manufacturing and assembly costs. The simplified design requires minimal materials and assembly steps.
Solution Approach 2:
The wringing function is segmented into a separate, independent rod component that can be manufactured and installed independently from the bucket, allowing for simplified production and easy replacement without affecting other system components.
4Reliability
If spin dry wringers made of hard plastic are used, then wringing function is achieved, but reliability decreases due to sun damage and breakage
Solution Approach 1:
The wringer rod is designed as a simple, potentially replaceable component that minimizes exposure to harmful environmental factors. Its simple construction and potential for replacement reduce the impact of sun damage and breakage on overall system reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device efficiently removes liquid from mop strings with low manufacturing costs, is durable, and ensures complete liquid extraction without breakage, providing a stable and effective mopping solution.
Implementation Method 1
The wringer engages the strings of the mop, and the handle of the mop is then twisted. The twisting causes the strings to tighten around the wringer, thereby forcing a cleaning liquid such as water from the strings.
Implementation Method 2
The twisting causes the strings to tighten around the wringer, thereby forcing a cleaning liquid such as water from the strings.

AI summary
A device for wringing a mop having a plurality of strings connected to a handle and a tailband connected to the strings, includes a bucket having a base connected to a wall. A wringer inwardly projects from the wall. The wringer is shaped and dimensioned to pass through the strings of the mop, so that when the mop is twisted the wringer captively engages the strings to effect a wringing action. In an embodiment, the wringer is a rod. In another embodiment, a friction-enhancing material is disposed on the bottom of the base. The friction-enhancing material prevents the bucket from moving as the mop is twisted and wrung out.
