Solution Overview
Problem
Existing methods for processing substrates to form predetermined surfaces, such as separating surfaces, often fail to achieve precise control due to mechanical damage and lack of control over the target area, leading to inconsistent results.
Innovation Solution
A method involving exposure of the substrate to an electromagnetic field in curved effective regions, causing nonlinear interaction that influences the substrate material, allowing for precise shaping and structuring of the surface without mechanical stress, including the formation of cracks, cavities, and changes in structure, enabling the creation of predetermined surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If mechanical cutting processes (scoring and breaking, wheel cutting, laser-based thermal cutting) are used to form predetermined surfaces, then the substrate can be processed to create separating surfaces, but the target area cannot be precisely achieved due to uncontrolled substrate damage
Solution Approach 1:
The patent replaces mechanical cutting processes (scoring and breaking, wheel cutting) with electromagnetic field exposure. The electromagnetic field causes nonlinear interaction with the substrate material, creating curved effective regions that precisely define the target area without mechanical contact or uncontrolled damage propagation.
Solution Approach 2:
The patent changes the physical state and properties of substrate material within curved effective regions through electromagnetic field exposure. This creates localized modifications (cracks, cavities, structural changes) that enable precise surface formation by controlling where and how the material responds, rather than relying on mechanical force distribution.
2Manufacturing precision
If electromagnetic field exposure in curved effective regions is used to structure the substrate surface, then precise control over the target area and surface shape is achieved, but the process complexity increases due to nonlinear interaction requirements
Solution Approach 1:
The patent introduces curved effective regions that extend into the volume of the substrate, not just along the surface. This volumetric approach allows the electromagnetic field to create three-dimensional modifications that directly determine the final surface shape, adding a depth dimension to the structuring process.
Solution Approach 2:
The electromagnetic field exposure performs preliminary modification of the substrate material within curved effective regions before final surface formation. This pre-structuring creates controlled damage zones and material property changes that guide subsequent surface development, simplifying the overall process control.
3Ease of manufacture
If conventional laser-based thermal cutting is used, then cutting can be performed without mechanical contact, but the specified target area is often not achieved due to thermal stress field limitations
Solution Approach 1:
The patent changes the interaction mechanism from linear thermal absorption to nonlinear electromagnetic interaction. This creates curved effective regions with intensified local effects, enabling precise target area definition through nonlinear material response rather than diffuse thermal stress fields.
Solution Approach 2:
The patent employs curved effective regions where the electromagnetic field intensity distribution follows curved patterns. This curvature concentrates the field energy in specific volumetric zones, creating precise modification regions that accurately define the target area, unlike linear or planar thermal fields.
