Abrasive Product Loop Melting to Prevent Cutting Contamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing abrasive products with hook and loop fastening systems suffer from loose loops formed during cutting, which contaminate the product and the grinded object, and current solutions like air suction or tacky layers are inadequate or costly.
Innovation Solution
The solution involves providing abrasive products with loops that can be melted and/or burnt to lose their form, forming a melted and/or burnt area on the substrate surface to prevent loose loops, achieved through methods like laser or ultrasound processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mechanical punching is used to cut abrasive products, then productivity is improved, but loose loops are formed that contaminate the product
Solution Approach 1:
The patent applies preliminary action by melting the loops at the cutting edges before the mechanical punching process. This pre-treatment ensures that when the cutting tool subsequently punches the abrasive product, the loops are already softened and do not detach as loose contaminants, thus preventing contamination while maintaining high productivity
Solution Approach 2:
The patent changes the physical parameter of the loop material by heating it to its melting point, transforming it from a solid state to a melted state. This parameter change causes the loops to lose their original form and prevents them from detaching during mechanical punching, thereby eliminating the contamination problem while preserving production efficiency
2Object-generated harmful factors
If a net cleaner device with pressurized air and suction is used, then loose loops are removed, but the solution is insufficient to perfectly satisfy end user requirements
Solution Approach 1:
Instead of attempting to remove loose loops after they are formed, the patent applies preliminary action by melting the loops before cutting occurs. This prevents the formation of loose loops in the first place, achieving near-perfect contamination prevention that post-processing cleaning methods cannot accomplish
Solution Approach 2:
The patent converts the potentially harmful loose loops into a beneficial state by melting them. The melted loops lose their ability to detach and contaminate, transforming from a harmful factor into a stable, integrated part of the abrasive product structure
3Object-generated harmful factors
If a tacky layer is applied against the loop side, then loose loops are prevented, but extra costs are incurred and manual removal is required
Solution Approach 1:
The patent extracts the problematic tacky layer from the solution and replaces it with a thermal processing approach. By melting the loops through heating, the invention eliminates the need for additional adhesive layers and the associated manual removal steps, simplifying the overall process while maintaining effectiveness
Solution Approach 2:
The patent replaces the mechanical/adhesive approach of tacky layers with a thermal approach. By using heat to melt the loops, the invention substitutes the complex mechanical system of adhesive application and manual removal with a simpler thermal processing system
