Wiper Mop Plate Joint Locking to Maintain Wringing Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wiper plates face difficulties in being easily fed into wringing devices due to joint tilting during pressing, which reduces the force applied and worsens the wringing result.
Innovation Solution
A locking device is integrated into the base body to fix the joint along the longitudinal axis when the wiper plate wings pivot from the working to the wringing position, preventing pivoting or tilting, and ensuring all applied force is utilized for wringing, with a universal joint design allowing pivoting in both directions and enhanced by spring mechanisms and stop elements for secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the joint is designed to be pivotable for ease of operation, then the ease of operation is improved, but the joint tilts during pressing which reduces the force applied and worsens the wringing result
Solution Approach 1:
The joint is designed with dynamic characteristics allowing pivoting during insertion, but includes a locking mechanism that activates in the wringing position to fix the joint and prevent tilting, thus maintaining full force application during wringing while preserving ease of insertion
2Force
If the joint is fixed along its longitudinal axis to prevent tilting, then the force applied is improved, but the device complexity increases due to the locking mechanism
Solution Approach 1:
The locking mechanism is designed to activate automatically when the mop plate wings are in the wringing position, fixing the joint along its longitudinal axis without requiring additional manual operation, thus preventing tilting and maintaining full force application while minimizing user burden
3Adaptability or versatility
If the mop plate wings are pivotable between working and wringing positions, then the adaptability is improved, but the joint tilting during position change reduces the wringing effectiveness
Solution Approach 1:
The joint allows dynamic pivoting during the transition from working to wringing position for adaptability, but includes a locking mechanism that activates in the wringing position to fix the joint and prevent tilting, thus maintaining full force application and wringing effectiveness
Solution Approach 2:
The locking mechanism automatically activates when the mop plate wings are in the wringing position, fixing the joint without requiring additional user action, thus ensuring reliable wringing effectiveness while maintaining adaptability
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 allows for effective wringing by maintaining the full force applied through the handle, improving the wringing result and preventing the wiper plate from folding over during cleaning, especially on damp floors.
Implementation Method 1
The first joint body (15) accommodates a spring needle (17) that extends through a longitudinal opening (18) provided in the first joint body (15). The second joint body (16) has a recess (19) that is congruent with the longitudinal opening (18) when the second joint body (16) is aligned relative to the first joint body (15) in the direction of the longitudinal axis (9).
