Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional grinding tools used in chemical mechanical polishing techniques face a challenge in maintaining optimal cutting rate without increasing the cost by distributing abrasive elements more densely, which is expensive and inefficient.
Innovation Solution
A grinding tool with a substrate and protruding grinding studs, where each stud has an abrasive particle with a pattern-cut tip forming multiple apexes, increasing the cutting rate without the need for additional abrasive particles, and a cost-effective fabrication method using adhesive layers and elastic pads to secure the studs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the distribution density of abrasive elements is increased to improve cutting rate, then the cutting rate is improved, but the manufacturing cost increases
Solution Approach 1:
The abrasive particle tip is segmented into multiple apexes by cutting patterns (e.g., cross-shaped, star-shaped, or radial patterns) that divide the original single tip into several cutting points. This segmentation allows one abrasive particle to function as multiple cutting elements, improving the cutting rate without adding more particles to the tool.
Solution Approach 2:
Instead of increasing the number of abrasive particles in the planar distribution, the invention transforms the cutting functionality by adding dimensional complexity to the particle tip itself through pattern cutting. This creates multiple apexes in three-dimensional space from a single particle, effectively increasing cutting capacity without increasing particle density.
2Productivity
If the quantity of abrasive elements is increased to improve cutting rate, then the cutting rate is improved, but the manufacturing complexity increases
Solution Approach 1:
The abrasive particle tip is segmented into multiple apexes by cutting patterns (e.g., cross-shaped, star-shaped, or radial patterns) that divide the original single tip into several cutting points. This segmentation allows one abrasive particle to function as multiple cutting elements, improving the cutting rate without adding more particles to the tool.
Solution Approach 2:
Multiple cutting apexes are merged into a single abrasive particle structure, combining the functionality of multiple particles into one. This merging approach achieves the cutting rate improvement of having multiple elements while avoiding the complexity of managing and distributing separate particles.
