Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual alignment of each printed circuit board is performed using conventional unline device, then alignment precision can be maintained, but alignment time increases and productivity decreases
Solution Approach 1:
The patent merges multiple alignment functions into a single batch alignment device that can align multiple printed circuit boards simultaneously. The device combines X-axis and Y-axis alignment mechanisms in one integrated system, allowing concurrent alignment of multiple PCBs rather than sequential individual alignment, thus maintaining precision while dramatically improving productivity
Solution Approach 2:
The alignment process is segmented into independent X-axis and Y-axis alignment operations that can be executed simultaneously on multiple PCBs. The batch alignment device divides the work area into multiple positioning zones, each capable of independent alignment adjustment, enabling parallel processing of multiple boards without compromising alignment accuracy
2Productivity
If multiple alignment devices are installed to align multiple objects simultaneously, then alignment speed improves, but equipment costs increase
Solution Approach 1:
The batch alignment device is designed as a universal alignment system that can handle multiple printed circuit boards of different sizes and configurations simultaneously. The device incorporates adjustable positioning mechanisms and scalable alignment zones, allowing a single multi-functional device to replace multiple dedicated alignment devices, thereby reducing equipment costs while maintaining high alignment speed
Solution Approach 2:
The patent transitions from one-dimensional sequential alignment to two-dimensional parallel alignment by utilizing both X-axis and Y-axis movements simultaneously. This dimensional expansion allows multiple PCBs to be aligned in a grid pattern across the work area, achieving high throughput without requiring proportional increases in equipment quantity
3Measurement precision
If individual alignment devices operate separately, then each device can maintain precision, but overall alignment time increases
Solution Approach 1:
The batch alignment device maintains continuous useful action by enabling simultaneous X-axis and Y-axis alignment operations on multiple PCBs throughout the work area. The coordinated movement system ensures that all alignment actions occur in parallel without idle time, eliminating the sequential waiting periods inherent in individual alignment devices and dramatically reducing total alignment time while preserving precision
