Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If alignment detection pins are added to detect misalignment, then alignment accuracy is improved, but device complexity increases
Solution Approach 1:
The detection function is segmented into two distinct pin types: signal connection pins for normal operation and alignment detection pins for alignment verification. This segmentation allows the alignment detection function to be added without interfering with the existing signal transmission function, resolving the contradiction by separating measurement and operational roles.
Solution Approach 2:
The alignment detection pins act as intermediary elements between the signal connection pins and the external alignment detection device. These intermediary pins transmit alignment information without carrying signal transmission loads, enabling precise alignment measurement while maintaining the integrity of the original signal connection system.
2Measurement precision
If more pins are added for alignment detection, then alignment detection capability is improved, but manufacturing complexity increases
Solution Approach 1:
The alignment detection pins are positioned at specific locations (both sides of the signal connection pins) where alignment information is most critical. This local placement strategy provides effective alignment detection capability while minimizing the total number of pins required, thereby reducing manufacturing complexity compared to a uniform distribution of detection pins.
Solution Approach 2:
The alignment detection pins are pre-positioned and pre-configured during substrate manufacturing, enabling alignment detection to be performed before final assembly. This preliminary action ensures that alignment issues are identified early, simplifying the overall manufacturing process by preventing misalignment-related rework in later stages.
3Reliability
If alignment detection is performed before signal connection, then short circuit risk is reduced, but detection time increases
Solution Approach 1:
Alignment detection is performed as a preliminary action before signal connection and testing. By detecting alignment issues beforehand, the system prevents short circuits from occurring during subsequent operations. This preliminary detection approach reduces overall risk and may save time by avoiding costly rework or device damage later in the process.
Solution Approach 2:
The alignment detection mechanism performs a preliminary anti-action by identifying and flagging misalignment conditions before they can cause harmful short circuits. This preventive measure counteracts the potential for damage by detecting alignment errors in advance, thereby protecting the system while maintaining an efficient detection sequence.
