Clip-Assembled Hollow Roller for Stable Sponge Board Wiping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rollers for scraping sponge boards over wash buckets are not easily manufactured and lack stability, leading to inefficient water drainage and cement residue removal during the cleaning process.
Innovation Solution
A roller designed as a hollow body with a profiled lateral surface featuring slot-shaped passage openings and consisting of two permanently connected half-shells via a clip connection, along with axially running webs and a radial stiffening element, enhances manufacturing ease and stability while ensuring effective water drainage and uniform stripping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the roller is designed as a hollow body with profiled lateral surface, then the water drainage efficiency is improved, but the manufacturing complexity increases
Solution Approach 1:
The roller is divided into two half-shells that can be manufactured separately and then assembled together. This segmentation allows each half-shell to be produced using simpler manufacturing processes while maintaining the complex profiled lateral surface with slot-shaped passage openings for efficient water drainage.
Solution Approach 2:
The two half-shells are nested together to form the complete hollow roller body. The clip connection system allows one half-shell to be attached to the other, creating the final hollow structure with the profiled lateral surface that enables effective water drainage while simplifying the manufacturing process.
2Ease of manufacture
If the roller consists of two half-shells connected via clip connection, then the ease of manufacture is improved, but the stability of the roller structure deteriorates
Solution Approach 1:
The roller is segmented into two half-shells connected by multiple pins distributed around the circumference. This segmentation enables easy manufacturing and assembly while the distributed pin connection provides sufficient structural stability for the roller to function effectively during sponge board wiping.
Solution Approach 2:
The two half-shells are merged together through the clip connection formed by pins engaging with receptacles. This combining method creates a unified roller structure that maintains stability during operation while allowing for easier manufacture and potential disassembly compared to traditional monolithic construction.
3Productivity
If multiple axially running webs are added to the roller surface, then the wiping effectiveness is improved, but the device complexity increases
Solution Approach 1:
The roller surface is equipped with axially running webs at specific locations to provide the necessary wiping effect. These webs are strategically positioned on the half-shells to enhance the squeezing action on the sponge board while maintaining a relatively simple overall roller design that does not require excessive structural complexity.

Function Achieved in This Case
The solution provides a stable and easy-to-manufacture roller that facilitates efficient water drainage and improved wiping effectiveness, ensuring thorough removal of cement residues from the sponge board.
Implementation Method 1
the water in the sponge is pressed out of the sponge and the cement or grout contained therein collects in the water of the tile washing bucket
