Floor Grinding Pad Assembly for Even Wear and Floor Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor polishing and grinding pad assemblies exhibit uneven wear, leading to premature degradation and inconsistent performance, which affects the quality of polishing and grinding operations on surfaces like concrete and stone.
Innovation Solution
A floor polishing or grinding pad assembly that incorporates a fibrous pad with a reinforcement layer and multiple floor-contacting disks, featuring a central hole with a larger linear dimension than the reinforcement layer, and disks with angle offsets and varying patterns, which ensures consistent wear and improved floor contact, enhancing the pad's longevity and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fibrous pads are used for floor polishing or grinding, then the pads can perform basic polishing or grinding functions, but they exhibit uneven wear which prematurely destroys the pads and causes inconsistent polishing or grinding performance
Solution Approach 1:
The pad assembly is divided into multiple functional segments: a fibrous pad layer for polishing/grinding, a reinforcement layer for structural support, and multiple floor-contacting disks distributed across the surface. This segmentation allows each component to perform its specific function optimally while working together to prevent uneven wear and extend service life.
Solution Approach 2:
The pad assembly uses composite construction combining different materials: fibrous material for abrasive contact, reinforcement layer material for structural integrity, and floor-contacting disk material for enhanced floor interaction. This composite structure distributes stresses and wear more evenly across the pad assembly, preventing premature failure and maintaining consistent performance throughout the service life.
2Strength
If the fibrous pad is reinforced with a reinforcement layer, then the structural integrity of the pad is improved, but the complexity of the pad assembly increases
Solution Approach 1:
The reinforcement layer is merged with the fibrous pad and floor-contacting disks into a single integrated pad assembly unit. This combining approach provides structural integrity through the reinforcement layer while maintaining ease of installation and operation by presenting a unified, pre-assembled component that attaches to the floor polishing or grinding machine as one unit.
3Reliability
If multiple floor-contacting disks are added to the pad assembly, then more even wear characteristics and improved floor contact are achieved, but the manufacturing complexity increases
Solution Approach 1:
The floor-contacting disks are pre-positioned and attached to the reinforcement layer during manufacturing, creating a pre-assembled pad unit with predetermined disk locations and orientations. This preliminary action ensures consistent disk distribution for even wear characteristics while simplifying the overall manufacturing process by allowing components to be prepared and positioned in advance rather than assembled during installation.

AI summary
A floor polishing or grinding pad assembly is provided. In one aspect, a polishing or grinding pad assembly employs a fibrous pad, a reinforcement layer or ring, and multiple floor-contacting disks. In another aspect, the reinforcement layer includes a central hole through which the fibrous pad is accessible and the fibrous pad at the hole has a linear dimension (x) greater than a linear dimension (y) of one side of the adjacent reinforcement layer. In yet another aspect, at least one of the floor-contacting disks has an angle (α) offset from that of a base surface of the disk, the fibrous pad and/or the reinforcement layer. A further aspect employs a smaller set of disks alternating between and/or offset from a larger set of the disks. In another aspect, the reinforcement layer includes a wavy or undulating internal edge shape.
