A floor polishing or grinding pad assembly featuring a fibrous pad with a reinforcement layer and multiple floor-contacting disks, where the disks have angle offsets and varying patterns, providing consistent wear characteristics and improved floor contact, thereby 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 the pads exhibit uneven wear which prematurely destroys the pads and causes inconsistent polishing or grinding
Solution Approach 1:
The pad assembly is segmented into multiple functional components: a fibrous pad layer for polishing/grinding, a reinforcement layer for structural support, and multiple floor-contacting disks distributed across the assembly. 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 material construction by combining different materials with complementary properties: fibrous materials for abrasive contact, reinforcement materials (such as woven or non-woven fabrics) for structural integrity, and disk materials for enhanced floor contact. This composite structure distributes stresses evenly and prevents premature failure.
2Reliability
If multiple floor-contacting disks with angle offsets are added to the pad assembly, then wear characteristics become more consistent and floor contact is improved, but the device complexity increases
Solution Approach 1:
The pad assembly is segmented into multiple functional components: a fibrous pad layer for polishing/grinding, a reinforcement layer for structural support, and multiple floor-contacting disks distributed across the assembly. 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 disks are pre-positioned at specific angle offsets and locations on the reinforcement layer before the pad assembly is installed on the polishing or grinding machine. This preliminary configuration ensures that the disks will contact the floor at optimal points during rotation, creating even wear patterns without requiring complex adjustment mechanisms during operation.
3Area of stationary object
If the fibrous pad at the central hole has a linear dimension greater than the reinforcement layer side, then greater floor contact is achieved in the centralized area, but the manufacturing precision requirements increase
Solution Approach 1:
The fibrous pad is designed with non-uniform dimensions, specifically making the pad material at the central hole area extend beyond the reinforcement layer boundaries. This local quality enhancement concentrates floor contact in the centralized area where it is most needed for polishing performance, while the rest of the pad maintains standard dimensions for structural integrity.

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 greater than a linear dimension of one side of the adjacent reinforcement layer. In yet another aspect, at least one of the floor-contacting disks has an angle 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.
