Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the second handle section is made hollow with threaded structure and spherical bodies for spindle drive, then the mop plate can be rotated for wringing, but the handle section becomes bulky and complex to manufacture
Solution Approach 1:
The invention extracts the spherical bodies and threaded structure from the handle section and relocates them to the spindle drive component. The handle section becomes a simple hollow tube without complex internal features, while the spindle drive contains all the rotational mechanism elements. This separation eliminates the complexity from the handle while preserving the wringing function.
Solution Approach 2:
The invention introduces an intermediary component (the spindle drive with integrated spherical bodies and threaded structure) that mediates between the handle and the mop plate. This intermediary contains all the complex rotational mechanism elements, allowing the handle itself to remain simple while still enabling the wringing function through the spindle drive's interaction with the mop plate.
2Ease of operation
If the second handle section is designed with threaded structure and spherical bodies, then the spindle drive can rotate the mop plate, but the manufacturing complexity increases
Solution Approach 1:
The invention extracts the threaded structure and spherical bodies from the handle section and consolidates them into the spindle drive component. This allows the handle to be manufactured as a simple hollow tube using standard processes, while the complex rotational mechanism is confined to the spindle drive which can be manufactured separately with appropriate precision requirements.
3Ease of operation
If a two-part handle with complex spindle drive is used, then the mop plate can be rotated for wringing, but the overall device weight increases
Solution Approach 1:
The invention extracts the heavy threaded structure and spherical bodies from the handle and relocates them to the spindle drive. This allows the handle to be made from lighter material with simpler construction, reducing overall weight while the spindle drive contains the necessary mass for the rotational mechanism.
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 solution enhances handling, reduces material usage and costs, allows for easier cleaning of hard-to-reach areas, and improves wringing efficiency while being ergonomic and easy to assemble/disassemble.
Implementation Method 1
the sleeve (8) has an internal thread (10) on its inner circumference, which engages with the spherical bodies (9) arranged on the spindle (7), so that the spherical bodies (9) slide along the thread structure of the sleeve (8) and thereby rotate the spindle (7) with the mop plate (4) fixed therein when the sleeve (8) is moved in translation
Implementation Method 2
A freewheel is provided to prevent the direction of rotation of the spindle from changing when the sleeve is moved in the other direction. As a result, rotational energy can only be introduced into the spindle in one direction.
