Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor polishing and grinding pads exhibit uneven wear, leading to premature degradation and inconsistent performance, as they fail to maintain consistent contact pressure and floor contact during rotation.
Innovation Solution
A floor polishing or grinding pad assembly featuring a flexible pad with a reinforcement ring and multiple abrasive tools of varying sizes and patterns, including disks with tapered angles, which ensures even wear and consistent contact pressure by alternating larger and smaller disks with offset placements, enhancing the pad's durability 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 be used on concrete, terrazzo, and natural stone floors, but the pads exhibit uneven wear which prematurely destroys them and causes inconsistent polishing or grinding
Solution Approach 1:
The pad assembly is segmented into multiple functional layers: a flexible fibrous pad layer, a reinforcement layer with radial and circumferential members, and a central support structure. This segmentation provides structural integrity while allowing the abrasive elements to maintain consistent contact pressure, preventing uneven wear and extending pad service life.
Solution Approach 2:
The pad assembly uses composite construction combining flexible fibrous materials with rigid reinforcement elements (radial and circumferential members). This composite structure maintains pad shape and contact pressure consistency during rotation, eliminating the uneven wear problem of traditional single-material pads while extending their operational duration.
2Area of stationary object
If traditional polishing pads rotate during use, then they can cover the floor surface, but they create inconsistent floor-contact pressure between middle and periphery
Solution Approach 1:
The reinforcement layer with radial and circumferential members creates an equipotential structure that distributes contact pressure uniformly across the pad surface. This ensures that both the middle and periphery areas maintain consistent floor-contact pressure during rotation, improving polishing consistency across the entire floor contact area.
3Duration of action of stationary object
If pads are made more durable to extend service life, then they can withstand longer use, but they may become less flexible and maintain poorer floor contact
Solution Approach 1:
The composite structure combines flexible fibrous pad material with rigid reinforcement members. The flexible pad material maintains floor contact capability and adaptability, while the rigid reinforcement members provide structural durability and prevent premature destruction, achieving both extended service life and maintained floor contact.
Solution Approach 2:
The flexible fibrous pad forms a compliant outer layer that can adapt to floor surface variations and maintain intimate contact, while the underlying rigid reinforcement structure provides durability. This flexible shell design allows the pad to extend service life without sacrificing floor contact capability.

AI summary
A floor polishing or grinding pad assembly is provided. In one aspects a polishing or grinding pad assembly employs a flexible pad, a reinforcement layer or ring, and multiple floor-contacting tools such as disks. In yet another aspect, at least one of the floor-contacting tools has a workpiece-contacting bottom plane having angle offset from that of a base surface of the tool, a flexible pad and/or a flexible reinforcement layer. A further aspect employs a smaller set of disks alternating between and/or offset from a larger set of the disks.
