Elastic Mop Wringer Structure for Higher Wringing Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mop wringers lack sufficient wringing power and efficiency, often requiring more force to effectively press the mop and can be cumbersome in design, limiting their performance and material usage.
Innovation Solution
The integration of elastic inner and outer legs connected by a stable spacer, which transfers deformation forces to create a compressive bending motion, enhancing wringing power and allowing for a thinner, more flexible design, along with the use of film hinges and spiral-shaped inner legs to improve force transfer and prevent bending, while maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional wringer designs are used, then the structure is simple, but the wringing power is insufficient
Solution Approach 1:
The patent applies the dynamics principle by making the inner legs elastic and capable of deformation. When the mop is pressed into the receptacle, the inner legs deform elastically, which drives the outer legs to move inward and press the mop. This dynamic mechanism transforms the simple pressing action into an effective wringing force, resolving the contradiction between simple structure and sufficient wringing power.
Solution Approach 2:
The patent changes the physical state and mechanical properties of the legs by making them elastic rather than rigid. The inner legs are designed to deform under compression, and the outer legs are designed to bend inward. This parameter change from rigid to elastic allows the structure to generate sufficient wringing force while maintaining relative simplicity.
2Force
If thicker and stiffer legs are used to increase wringing power, then the wringing performance improves, but the material usage increases and flexibility decreases
Solution Approach 1:
By making the legs elastic and dynamic rather than statically thick and stiff, the patent achieves high wringing power with less material. The elastic deformation of the inner legs and bending motion of the outer legs create mechanical advantage, allowing thinner legs to generate sufficient force.
Solution Approach 2:
The patent changes the material property parameter from rigid to elastic, allowing the legs to deform and store/release mechanical energy. This enables the use of less material while maintaining or improving wringing performance, as the elastic properties provide mechanical leverage.
3Stability of the object's composition
If the outer legs are made rigid to maintain structural stability, then the structure is stable, but the flexibility and adaptability to mop pressure decreases
Solution Approach 1:
The patent makes the outer legs elastic and capable of bending motion rather than rigid and fixed. When the inner legs deform under mop pressure, the outer legs bend inward dynamically, adapting to the applied force while maintaining structural integrity. This dynamic flexibility resolves the contradiction between stability and adaptability.
4Force
If more force is applied to press the mop into the receptacle, then the wringing effectiveness increases, but the ease of operation decreases
Solution Approach 1:
The elastic inner legs and bending outer legs create a mechanical system that amplifies the user's pressing force. The deformation and recovery of these elastic components generate additional wringing force automatically, reducing the effort required from the user while maintaining high wringing effectiveness.
Solution Approach 2:
The wringer design allows the elastic legs to automatically generate wringing force through their deformation and recovery cycles. The system serves itself by converting the pressing motion into effective wringing action through the mechanical properties of the elastic legs, reducing the need for additional user force.
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
This configuration enhances wringer performance by increasing the compressive bending deformation, allowing for tighter closure with less force, improved material efficiency, and easier manufacturing, while also preventing mop string slippage and facilitating easier mop insertion.
Implementation Method 1
The inner and outer legs are designed in accordance with the invention to be elastic and the spacer is designed to be stable in tension or under pressure in order to be able to transfer forces from the inner leg to the outer leg. When a mop is pressed into the receptacle, the inner leg gives and, in doing so, becomes elastically deformed.
Implementation Method 2
The deflection of the inner leg is transferred through the minimum of one spacer to the outer leg due to the connection between the inner and outer legs.
Implementation Method 3
The outer leg acts as a compressive and elastic bending rod. When a force is applied to the inner leg, the inner leg exerts a tensile force on the end of the outer leg, which stretches the outer leg and bends it in an arc. The outer leg produces a counterforce to the tensile force, and the outer leg is subject to a compressive bending stress.
