Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Abrasive wheels used for cutting and grinding materials like metal are prone to fatigue and failure, limiting their usage time due to stiffness and lack of compliance, which affects their performance and durability.
Innovation Solution
Development of thin, pliable abrasive wheels with varying thickness and reinforcement layers, such as fiberglass webs, within a bonding material, allowing for deflection without breaking and enhanced contact with workpieces, along with a coating that controls water vapor transmission to maintain performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If abrasive wheels are made thin for efficient cutting, then cutting efficiency is improved, but they become more prone to fatigue and failure
Solution Approach 1:
The abrasive wheel uses a composite structure combining abrasive grains with a flexible bonding agent matrix. This composite design allows the wheel to remain thin for efficient cutting while the bonding agent provides flexibility and fatigue resistance, preventing the wheel from breaking during operation.
Solution Approach 2:
The patent changes the physical parameters of the bonding agent to achieve optimal flexibility and strength. By adjusting the bonding agent's mechanical properties, the wheel can withstand the stresses of thin-profile cutting without failing, resolving the contradiction between thin profile benefits and fatigue resistance.
2Manufacturing precision
If abrasive wheels are made rigid for structural stability, then manufacturing precision is improved, but compliance and contact with workpieces deteriorate
Solution Approach 1:
The patent modifies the rigidity parameter of the bonding agent to achieve an optimal balance. The bonding agent is formulated to provide sufficient structural stability for manufacturing precision while maintaining enough compliance to contact workpieces effectively during cutting and grinding operations.
Solution Approach 2:
The composite structure combines rigid abrasive grains with a flexible bonding agent matrix. This allows the overall wheel structure to maintain stability for precision manufacturing while the flexible bonding agent provides the necessary compliance for workpiece contact, resolving the contradiction between rigidity and compliance.
3Productivity
If abrasive wheels are used continuously for extended periods, then productivity is improved, but performance degradation and failure increase
Solution Approach 1:
The patent adjusts the chemical and physical parameters of the bonding agent to resist degradation over time. The bonding agent is formulated to maintain its adhesive and flexible properties during continuous use, preventing performance degradation and extending the wheel's service life and productivity.
Solution Approach 2:
The patent designs the abrasive wheel as a consumable product with optimized bonding agent that extends its usable life. By carefully selecting and formulating the bonding agent, the wheel achieves extended usage time while maintaining reliability, effectively treating it as a disposable tool with extended service life rather than a permanent component.
