Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels are prone to cracks and bruises during manufacturing processes due to impacts during transportation and inspection, which existing technologies fail to adequately address.
Innovation Solution
A display panel inspection device with a base plate and a hollow-shaped jig that includes impact members, allowing for controlled collisions to calculate and adjust the impact applied to the panel, thereby preventing cracks and bruises by adjusting the transportation speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the display panel is transported during manufacturing process, then the manufacturing process can proceed, but cracks and bruises may occur due to impact
Solution Approach 1:
The patent applies preliminary action by pre-positioning impact members (protrusions) on the support structure before the display panel is transported. These impact members are strategically placed to provide controlled support points that prevent uncontrolled impacts during transportation, thereby maintaining panel integrity while enabling continuous manufacturing processes.
2Reliability
If impact members are added to the support structure, then the display panel is protected from cracks and bruises, but the device complexity increases
Solution Approach 1:
The patent applies local quality by adding impact members only at specific critical locations on the support structure where impacts are most likely to occur during transportation. Rather than uniformly protecting the entire structure, impact members are strategically positioned at corners and edges of the display panel, providing targeted protection while minimizing overall device complexity.
3Measurement precision
If the base plate and jig are made movable and rotatable, then the impact calculation is more accurate, but the device complexity increases
Solution Approach 1:
The patent applies dynamics by making the base plate and jig movable and rotatable rather than fixed. This allows the support structure to dynamically adjust to the display panel's position and orientation during transportation, enabling more accurate measurement of actual impact forces. The movable design captures real-world transportation conditions more faithfully, improving impact calculation accuracy despite increased mechanical complexity.
