Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If aging signals are supplied to multiple display panels simultaneously through line boards, then aging efficiency is improved, but error detection and isolation capability deteriorates
Solution Approach 1:
The system divides display panels into multiple panel groups, with each group connected to dedicated switch signal lines. Switch units within each panel group can be independently controlled, allowing error isolation to specific groups while maintaining aging operations in other groups. This segmentation enables simultaneous aging of multiple panels while preserving error detection and isolation capabilities.
Solution Approach 2:
Switch units act as intermediary components between the aging device and display panels. These switch units can selectively block or transmit aging signals based on detected errors, serving as mediators that enable both simultaneous aging operation and error isolation. The switch units provide a control mechanism that reconciles the contradiction between bulk aging and individual error handling.
2Reliability
If switch units are added to selectively block signals for error isolation, then error detection capability is improved, but device complexity increases
Solution Approach 1:
The switch units are integrated within the existing panel group structure, combining error detection and signal blocking functions into the current aging system architecture. Rather than adding completely separate error detection systems, the switch units leverage the existing panel group organization, reducing overall system complexity while maintaining error detection capability.
Solution Approach 2:
The switch units serve multiple functions: they control signal transmission for error isolation, enable selective aging of panel groups, and provide a mechanism for both detection and response to errors. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while achieving improved error detection capability.
