Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grinding tools face challenges in cooling, leading to premature degradation due to elevated temperatures during floor grinding and polishing operations, with conventional methods involving excessive water use resulting in heavy slurry formation and disposal issues.
Innovation Solution
A carrier disk with radially extending flanges and an air supply system that conducts heat away from grinding tools through conduction and convects heat via air flow, providing improved cooling and dust removal while maintaining user friendliness and compatibility with existing tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a massive amount of water is applied to cool grinding tools, then the cooling effect is improved, but slurry formation and disposal problems occur
Solution Approach 1:
The patent applies pneumatic cooling by directing compressed air flows through channels in the carrier disk and onto the grinding tools. This replaces the hydraulic cooling method (water application) with a pneumatic system, achieving cooling without slurry formation. The air flows are delivered through multiple channels (first and second air flows) that target different areas of the grinding tools.
Solution Approach 2:
The patent changes the cooling medium from liquid (water) to gas (compressed air). This parameter change fundamentally alters the cooling mechanism - air cooling provides sufficient heat dissipation without the adhesive properties of water that cause slurry formation with grinding residues.
2Object-generated harmful factors
If limited cooling fluid is applied to keep grinding residues dry, then slurry disposal is improved, but cooling effectiveness is reduced
Solution Approach 1:
The system uses compressed air delivered through multiple pneumatic channels to provide effective cooling. The pneumatic system delivers sufficient cooling capacity without requiring any liquid cooling fluid, thus keeping grinding residues dry while maintaining adequate temperature control.
3Temperature
If conventional cooling methods are used, then tool temperature reduction is achieved, but tool life is reduced due to slurry accumulation
Solution Approach 1:
By using compressed air instead of water for cooling, the system eliminates slurry accumulation on grinding tools. This pneumatic cooling method extends tool life by preventing the degradation that occurs when diamond abrasive tools are subjected to slurry buildup, while still achieving effective temperature reduction.

Implementation Method 1
at least one cutting, grinding or polishing element is cooled through conduction, i.e. heat is conducted away from the element to the carrier disk
Implementation Method 2
the elements and the carrier disk are cooled also through the convection caused by the air flowing radially outwardly past the elements
Implementation Method 3
providing improved cooling and dust removal
