Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for manufacturing display devices are complex and costly due to the need for separate processes to cut and chamfer glass panels, which complicates the cutting of substrates and subsequent smoothing of cut surfaces.
Innovation Solution
An optical panel cutting device utilizing a light converter, projection lens, beam splitter, and objective lens to generate a beam with a primary peak and secondary peaks of varying intensity, allowing simultaneous cutting and chamfering of glass panels, with the beam splitter's diffractive optical element adjusting the relative intensity and position of the peaks to achieve desired edge profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate processes are used for cutting and chamfering glass panels, then cutting precision can be maintained, but manufacturing complexity and cost increase
Solution Approach 1:
The patent combines cutting and chamfering operations into a single laser processing step by using a multi-peak laser beam. The primary peak performs cutting while secondary peaks perform chamfering simultaneously, eliminating the need for separate processing steps and reducing manufacturing complexity.
Solution Approach 2:
The laser beam is segmented into multiple peaks with different intensity distributions. The primary peak (higher intensity) is positioned at the cutting line for precise cutting, while secondary peaks (lower intensity) are positioned at offset locations to perform chamfering, allowing both functions to be achieved through beam segmentation.
2Manufacturing precision
If multiple processing steps are used for cutting and edge smoothing, then quality can be maintained, but production time increases
Solution Approach 1:
The patent merges cutting and edge smoothing (chamfering) into a single simultaneous operation using a multi-peak laser beam. This eliminates sequential processing steps, reduces total production time, and maintains edge quality through coordinated intensity distribution of the beam peaks.
Solution Approach 2:
The multi-peak laser beam enables continuous simultaneous action of both cutting and chamfering operations in one pass. The primary and secondary peaks act continuously on the glass panel during a single traversal, eliminating idle time between separate operations and improving production efficiency.
3Device complexity
If a single laser beam is used for both cutting and chamfering, then process complexity is reduced, but beam control precision must increase
Solution Approach 1:
The laser beam is segmented into multiple distinct peaks with specific spatial separation. The primary peak is positioned precisely at the cutting line while secondary peaks are positioned at predetermined offset distances. This segmentation allows each peak to be independently controlled for its specific function, reducing the overall control complexity compared to modulating a single beam.
Solution Approach 2:
The patent uses parameter changes in the laser beam's intensity distribution to achieve different functions. By varying the intensity and position of multiple peaks within the single beam structure, the system can perform cutting (high intensity at primary peak) and chamfering (lower intensity at secondary peaks) simultaneously, simplifying the overall process while maintaining precision through parameter control.
