Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If current mail processing systems individually retrieve and process sheets from stacks, then each sheet can be processed, but the process becomes expensive and inefficient for high volumes
Solution Approach 1:
The system segments the sheet processing into two independent streams: a first stream processes sheets through the alignment mechanism in a first direction, while a second stream processes sheets through the same alignment mechanism in a second direction. This segmentation allows parallel processing of multiple sheets simultaneously, dramatically increasing productivity without requiring proportionally more complex equipment.
Solution Approach 2:
The alignment mechanism serves multiple functions: it aligns sheets in the first direction for reading identification codes, aligns sheets in the second direction for matching with accumulated sheets, and acts as a common resource for both processing streams. This multi-functionality reduces the need for separate alignment mechanisms for each stream, thereby reducing device complexity while maintaining high processing capacity.
2Adaptability or versatility
If sheets from different batches with varying bar code locations are processed, then versatility is improved, but measurement precision deteriorates
Solution Approach 1:
The system dynamically adjusts the position of the sensor relative to the sheets being processed. Rather than requiring fixed bar code locations, the sensor can be repositioned to accommodate varying bar code positions across different batches. This dynamic adjustment capability allows the system to maintain measurement precision while processing sheets with varying bar code locations, thereby achieving both versatility and precision.
Solution Approach 2:
The alignment mechanism performs preliminary alignment of sheets in the first direction before the sensor reads the identification codes. This preliminary alignment ensures that regardless of where the bar code is located on the sheet, the sensor will be in the correct position to read it accurately. By performing this alignment action in advance, the system maintains measurement precision while accommodating batch flexibility.
3Productivity
If sheets are advanced in perpendicular directions through the alignment mechanism, then processing efficiency is improved, but device complexity increases
Solution Approach 1:
The system merges two sheet processing streams into a single alignment mechanism. Sheets from the first stream and sheets from the second stream both pass through the same alignment mechanism, which handles them in perpendicular directions. This merging eliminates the need for separate alignment mechanisms for each stream, reducing device complexity while maintaining the efficiency benefits of perpendicular processing.
Solution Approach 2:
The system introduces a second directional dimension for sheet processing through the alignment mechanism. By advancing sheets in perpendicular directions (first direction and second direction) through the same mechanism, the system utilizes spatial dimensionality to increase processing efficiency. The alignment mechanism is designed to accommodate this multi-dimensional operation, managing the complexity through integrated design.
