Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual tool changes are performed between different grit sizes, then different surface finishes can be achieved, but processing time increases and operational efficiency decreases
Solution Approach 1:
The patent combines multiple abrasive sections with different grit sizes into a single tool body, allowing all grit sizes to work simultaneously on the concrete surface. This merging eliminates the need to change tools between grinding stages, thereby maintaining surface finish quality while significantly improving processing efficiency and reducing downtime.
Solution Approach 2:
The abrasive tool is designed with multi-functionality by incorporating various grit sizes (e.g., 400, 800, 1500, 3000) within one tool structure. This enables the single tool to perform multiple functions: coarse grinding, fine grinding, and polishing, replacing the need for multiple specialized tools and eliminating tool change operations.
2Reliability
If multiple separate tools are used for different grit sizes, then each tool can be optimized for its specific function, but tool complexity and inventory requirements increase
Solution Approach 1:
Multiple abrasive sections with different grit sizes are integrated into a single tool body with a common mounting interface. This merging reduces the number of separate tools from four (one for each grit size) to one, simplifying the tool system while maintaining the functional performance of each grit level through dedicated sections.
Solution Approach 2:
The tool body is segmented into multiple independent abrasive sections, each optimized for a specific grit size and function. This segmentation allows each section to maintain its specialized functional performance while being part of a unified tool structure, reducing overall system complexity by consolidating multiple tools into one.
3Manufacturing precision
If tool changes are required for each grit size, then precise control over grinding stages is achieved, but operational downtime increases
Solution Approach 1:
The multi-section abrasive tool enables continuous useful action by allowing all grit sizes to operate simultaneously on different areas of the concrete surface without interruption. The tool eliminates idle time associated with tool changes, maintaining continuous grinding action while progressing through different stages of surface refinement.
Solution Approach 2:
All abrasive sections are pre-configured in the tool body before operation begins. This preliminary arrangement of different grit sizes eliminates the need for sequential tool changes, allowing the operator to immediately engage all grinding stages without downtime for tool replacement or reconfiguration.

Function Achieved in This Case
Facilitates efficient and continuous concrete surface processing with reduced downtime, enabling autonomous or semi-autonomous operation and optimized tool usage based on surface conditions and desired outcomes.
Implementation Method 1
The abrasive tool comprises at least two sections separated by a surface transversal to the wear direction. At least two sections comprise respective abrasive materials associated with different grit sizes, where the section located closer to the grinding surface is associated with a larger grit size compared to the section located closer to the mounting surface.
