Wet Cleaning Roller Braking Element for Low-Liquid Regeneration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wet cleaning devices require excessive amounts of cleaning liquid and have long regeneration times due to the inefficiency of removing dirt from the cleaning roller during the regeneration process.
Innovation Solution
A wet cleaning device equipped with a braking element that decelerates the rotating cleaning roller's fibers, causing a whiplash effect to dislodge dirt and liquid, allowing for more efficient regeneration with reduced liquid usage and shorter regeneration times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cleaning roller rotates at high speed during regeneration to fling off dirt using centrifugal forces, then dirt removal effectiveness is improved, but the amount of cleaning liquid required increases and regeneration time increases
Solution Approach 1:
The braking element induces vibrational motion in the cleaning roller during regeneration. The periodic contact between the braking element and the roller surface creates oscillations that enhance the separation of dirt from the cleaning surface, improving dirt removal effectiveness without relying solely on high-speed rotation and excessive liquid application.
2Productivity
If the cleaning roller rotates at high speed during regeneration to fling off dirt, then dirt removal effectiveness is improved, but regeneration time increases
Solution Approach 1:
The braking element is applied periodically or intermittently during the regeneration process rather than continuously. This periodic application creates repeated deceleration cycles that effectively dislodge dirt accumulations, achieving thorough cleaning in a shorter overall regeneration time compared to continuous high-speed rotation.
3Quantity of substance
If the braking element is applied to slow down the cleaning roller during regeneration, then liquid usage is reduced and regeneration time is shortened, but the complexity of the device increases
Solution Approach 1:
The braking element serves as a simple intermediary component between the cleaning roller and the control system. It provides a straightforward mechanical means to decelerate the roller without requiring complex control systems, sensors, or multiple actuators, thus minimizing the increase in device complexity while achieving reduced liquid usage and shorter regeneration time.
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 braking element enhances the cleaning effect with less liquid, enabling better dirt removal and reducing the speed of the cleaning roller while maintaining effectiveness, particularly beneficial for mobile wet cleaning devices.
Implementation Method 1
The inertia of the abruptly decelerated fibers creates a whiplash effect, tearing out liquid and dirt adhering between the fibers of the cleaning surface.
Implementation Method 2
a large amount of cleaning fluid is required to moisten or rinse the wiper body in order to fling off dirt accumulated on the wiper body using the centrifugal forces generated during the rotation of the wiper body
