Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor polishing machines using abrasive brushes face inefficiencies due to varying effective areas and non-uniform performance, particularly with abrasive brushes, leading to untreated strips and the need for multiple passes to achieve uniform results.
Innovation Solution
A polishing device with a circular pad featuring radially extending slots and blades secured by protrusions, which includes a trapezoidal body and abrasive elements to ensure uniform pressure distribution and continuous treatment, compatible with standard floor cleaning machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If abrasive brushes are used with extended abrasive elements outside the base footprint, then the effective area is increased, but the uniformity of performance deteriorates due to reduced support and increased bending
Solution Approach 1:
The brush is divided into multiple independent abrasive elements (blades) that are individually supported by the base structure. Each blade can be optimized for uniform pressure distribution while maintaining the overall extended effective area, resolving the contradiction between increased area and maintained performance uniformity.
Solution Approach 2:
Different portions of the brush base are designed with varying support characteristics to compensate for the bending effects of extended abrasive elements. The base structure provides enhanced support at critical locations to ensure uniform pressure distribution across all abrasive elements, maintaining performance uniformity while preserving extended effective area.
2Productivity
If multiple brush devices are used to increase cleaning area, then the productivity is improved, but the complexity of the device increases
Solution Approach 1:
Multiple brush devices are merged into a single integrated brush assembly with a unified base structure. This consolidation maintains the increased cleaning area provided by multiple brushes while reducing operational complexity through a single cohesive unit that functions as one integrated system.
3Productivity
If abrasive brushes with high material removal capability are used, then the productivity is improved, but the durability deteriorates leading to more frequent replacements
Solution Approach 1:
The brush employs composite construction combining durable base materials with high-performance abrasive elements. This composite design enables the brush to maintain both high material removal capability and extended service life, as the durable base structure supports the abrasive elements while resisting degradation from intensive use.
