Ceramic Cutting Blade Stabilization via Conical Geometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ceramic cutting machines suffer from geometric tolerances in their scoring wheels, leading to imprecise cuts due to oscillations and movements of the scoring blade, which affect the quality of the cut made on ceramic tiles.
Innovation Solution
A blade with a circular disc-shaped geometry and conical surfaces, where the ratio of the cutting diameter to twice the diameter of an imaginary sphere is between 1.5 and 1.7, optimizing mass and volume distribution around the symmetry axis for reduced vibrations and improved stabilization.

Engineering Contradiction Analysis
1Manufacturing precision
If conventional scoring blades with standard geometric tolerances are used, then manufacturing is easier and cost is lower, but cutting precision deteriorates due to oscillations and movements during cutting
Solution Approach 1:
The patent applies parameter changes by optimizing the geometric parameters of the scoring blade, specifically the ratio between the cutting diameter H and the diameter D of the imaginary sphere (H/D = 1.5-1.7). This parameter optimization redistributes mass and volume around the symmetry axis, reducing oscillations and improving cutting precision without requiring complex manufacturing processes
Solution Approach 2:
The patent utilizes spheroidality by introducing conical surfaces that are tangent to an imaginary sphere centered on the blade's symmetry axis. This spherical geometric feature helps stabilize the blade during rotation and cutting, reducing oscillations and improving guidance precision while maintaining manufacturability
2Stability of the object's composition
If the blade mass is distributed evenly, then manufacturing is simpler, but vibration stability deteriorates during cutting operation
Solution Approach 1:
The patent applies local quality by creating non-uniform mass distribution through conical surfaces that concentrate mass around the symmetry axis. This localized mass concentration improves rotational stability and reduces vibrations during cutting, while the conical geometry remains manufacturable using standard machining processes
