Solution Overview
Problem
Manual inspection of pressure points on liquid crystal display panels is time-consuming and prone to inaccuracies, often missing pressure points and resulting in poor quality.
Innovation Solution
A pressure point inspection device with adjustable lateral and vertical adjustment boards and multiple inspection heads that can be precisely positioned to inspect multiple pressure points simultaneously, reducing inspection time and ensuring all points are checked.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual inspection is used to check pressure points, then inspection flexibility is maintained, but inspection time increases and accuracy decreases
Solution Approach 1:
The inspection device divides the inspection task into multiple independent inspection heads, each responsible for a specific pressure point. This segmentation allows simultaneous inspection of multiple points, dramatically reducing inspection time from sequential manual checking to parallel automated checking.
Solution Approach 2:
The patent replaces the manual mechanical inspection process with an automated mechanical inspection system. The adjustable inspection heads are positioned to contact pressure points automatically, eliminating the need for manual operation while maintaining inspection flexibility through adjustable positioning mechanisms.
2Measurement precision
If multiple inspection heads are used to check all pressure points simultaneously, then inspection accuracy improves, but device complexity increases
Solution Approach 1:
The inspection device uses a universal adjustable framework that can accommodate multiple inspection heads in different positions. The lateral and vertical adjustment boards provide a multi-functional platform that can be configured for various pressure point arrangements, reducing device complexity by using a standardized adjustable structure rather than custom-built positions for each inspection point.
Solution Approach 2:
The inspection heads are mounted on adjustable lateral and vertical boards that can be dynamically repositioned. This dynamic adjustment capability allows the same device structure to adapt to different pressure point configurations, maintaining inspection accuracy while avoiding the need for complex fixed structures for each specific application.
3Adaptability or versatility
If adjustable lateral and vertical boards are used to position inspection heads, then adaptability to different panel configurations improves, but device complexity increases
Solution Approach 1:
The adjustment mechanism uses a nested structure where the vertical adjustment board is positioned on top of the lateral adjustment board, creating a hierarchical positioning system. This nesting allows two-dimensional adjustment (lateral and vertical) using a compact layered structure, achieving high adaptability while minimizing the space and complexity required for the adjustment mechanism.
