Cleaning roller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning rollers with foam cores often fail to maintain full-surface contact on uneven surfaces, leading to reduced cleaning effectiveness and potential wrinkling of the roller jacket during use.
Innovation Solution
Incorporating a plurality of spring elements around the bearing of the roller core, which extend to the roller shell, providing increased spring force and a larger contact surface, while maintaining a constant circumference to prevent wrinkling, and allowing for even weight distribution across the edge areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a foam roller core is used, then the structure is simple and easy to manufacture, but the spring force is insufficient and the roller shell wrinkles during cleaning
Solution Approach 1:
The roller core is segmented into multiple independent spring elements arranged circumferentially around the bearing. Each spring element extends from the bearing to the roller shell, providing distributed spring force throughout the roller structure rather than relying on a single foam core material property.
Solution Approach 2:
The spring elements are made of elastically deformable material (plastic or metal) that can be extruded or injection molded. The material parameters and geometric dimensions of the spring elements can be optimized to achieve the desired spring force characteristics, replacing the fixed properties of foam material.
2Area of stationary object
If the roller shell is pressed against the surface with increased spring force, then the contact surface area increases, but the circumference of the roller may change causing wrinkling
Solution Approach 1:
The spring elements are designed to be elastically deformable, allowing them to dynamically adjust their length and position in response to surface irregularities. This dynamic adaptation enables the roller shell to maintain constant circumference while achieving full-surface contact through the elastic deformation of the spring elements.
Solution Approach 2:
The roller shell is designed as a flexible structure that can adapt to surface contours. The combination of the flexible roller shell and the elastic spring elements allows the system to maintain its overall shape and circumference while achieving conformal contact with uneven surfaces.
