Electronic Device Protection Elements for Laser-Assisted Panel Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing process for electronic devices involves cutting mother substrates into smaller panels, which increases the time required for polarizer disposition due to the increased number of panels, leading to reduced manufacturing yield.
Innovation Solution
A method is introduced where protection elements are disposed on the substrates before polarizers, with varying widths of insulating layers, and openings are formed using lasers to facilitate efficient cutting, thereby reducing substrate damage and increasing yield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If mother substrates are cut into smaller panels, then the number of panels increases, but the time required for polarizer disposition increases
Solution Approach 1:
The patent applies preliminary action by disposing protection elements on the mother substrates before cutting and before polarizer disposition. This preliminary protective measure enables subsequent faster processing by preventing substrate damage during cutting, allowing the polarizer disposition to be completed more efficiently across the increased number of smaller panels
2Quantity of substance
If mother substrates are cut into smaller panels, then the number of panels increases, but the manufacturing yield decreases
Solution Approach 1:
The patent implements beforehand cushioning by introducing protection elements on the substrates prior to cutting. These protection elements act as a cushioning layer that prevents substrate damage during the cutting process, thereby maintaining manufacturing yield while enabling production of a larger number of smaller panels
3Object-affected harmful factors
If protection elements are disposed on substrates before polarizers, then substrate damage is reduced, but the process complexity increases
Solution Approach 1:
The patent applies the intermediary principle by introducing protection elements as a mediator between the cutting process and the substrate. These protection elements serve as a protective intermediary layer that prevents direct damage to the substrate during cutting, reducing substrate damage while the elements themselves are subsequently removed after polarizer disposition
