Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a substrate transfer device is used in liquid crystal display panel manufacturing, then substrate transfer between apparatuses can be achieved, but the transfer precision and efficiency are insufficient leading to potential substrate damage
Solution Approach 1:
The supporting assembly is divided into multiple supporting prongs that can independently support different regions of the substrate. This segmentation allows for more precise positioning and reduces the risk of substrate damage during transfer, directly improving transfer precision while maintaining reliability.
Solution Approach 2:
The patent replaces traditional mechanical connection methods with magnetic field-based connection. The connection assembly uses magnetic attraction to securely hold the substrate during transfer, providing more precise and controlled substrate handling compared to mechanical clamps, thereby improving both transfer precision and reliability.
2Productivity
If traditional substrate transfer methods are used, then substrate transfer can be performed, but operational complexity increases and efficiency decreases
Solution Approach 1:
The supporting assembly can support substrates of different sizes and the connection assembly can connect to different apparatuses, making the transfer device universally applicable. This multi-functionality improves transfer efficiency by eliminating the need for multiple specialized devices while the modular design keeps overall complexity manageable.
Solution Approach 2:
The magnetic connection assembly automatically attracts and secures the substrate without requiring complex mechanical adjustment mechanisms. This self-service capability simplifies the device structure, reduces operational complexity, and improves transfer efficiency by enabling faster substrate handling.
