Rotary segmented floor stripping pad
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary floor pads for stripping wax floors lack an aggressive stripping edge, leading to longer stripping times and require frequent changes due to wax buildup and clogging, increasing costs and inefficiency.
Innovation Solution
A segmented rotary floor stripping pad with symmetrical, polygonal segments made from open-textured non-woven polymer fibers, secured together with overlapping edges to form an annular shape, providing angled cutting edges and radial channels for air and fluid flow, which allows for aggressive wax stripping and reduces wax buildup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a flat monolithic surface pad is used, then the pad structure is simple and easy to manufacture, but the stripping edge is not aggressive and stripping time is extended
Solution Approach 1:
The pad is divided into multiple wedge-shaped segments arranged radially around a central hub. Each segment has an angled leading edge that provides aggressive stripping action. The segmentation allows the pad to maintain structural simplicity while achieving high productivity through the cumulative effect of multiple cutting edges rotating against the floor surface.
2Duration of action of moving object
If a monolithic porous material pad is used, then the pad is easy to manufacture, but the porous material quickly builds up and clogs with wax and stripping fluid
Solution Approach 1:
The segmented design allows the pad to be manufactured from simple porous materials while extending service life. The radial channels formed between segments prevent wax and fluid buildup by allowing centrifugal force to eject materials outward during rotation. This segmentation maintains manufacturing ease while dramatically improving durability and reducing the frequency of pad changes.
Solution Approach 2:
The radial channels between segments create fluid dynamics that exploit centrifugal force during rotation. Striping fluid and wax buildup are continuously ejected radially outward through these channels, preventing clogging and extending pad life without complicating the manufacturing process.
3Reliability
If frequent pad changes are made to avoid wax buildup, then the pad surface remains clean, but the job takes longer and costs more
Solution Approach 1:
The segmented structure with radial channels allows the pad to self-clean during operation. Wax and stripping fluid are continuously ejected through the channels between segments, maintaining cleaning effectiveness throughout the pad's service life. This eliminates the need for frequent pad changes and reduces downtime without compromising reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The segmented pad design enables faster wax removal and longer pad life by maintaining cleanliness and preventing wax buildup, reducing the need for frequent changes and lowering operational costs.
Implementation Method 1
The segments are preferably formed from open-textured, non-woven polymer fibers
Implementation Method 2
The rotary motion of the pad also centrifugally pushes stripping fluid and stripped wax material radially outward along the channels
Implementation Method 3
Abrasive particles may be dispersed throughout the pad material and are bonded to the material with a durable resin system

AI summary
The present disclosure provides a segmented rotary floor stripping pad having a plurality of symmetrical, polygonal pad segments secured together in partially overlapping relation to form an annular pad. The segments are preferably formed from non-woven polyester fibers and are secured radially along the overlapping, adjacent side edges by hot melt glue, ultrasonic welding or by stitching. There is no backing pad, and since the segments are symmetrical, the pad is reversible so that both sides can be used. The plurality of pad segments are secured together in an overlapping manner such that each pad segment presents an angled leading cutting edge and each pair of adjacent pad segments forms a radial fluid channel. Depending on the degree of overlap and the thickness of the pad segment, the presentation angle of the cutting edge can be varied.
