Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manufacturing processes are used for single-dose capsules, then production can be maintained at current levels, but production rate remains low and costs remain high
Solution Approach 1:
The manufacturing process is divided into distinct modular stations: conveying station for shell transport, forming station for filter creation, welding station for assembly, and adjusting station for positioning. Each station performs a specific function, enabling continuous high-speed production while maintaining process simplicity and controlling costs through modular design.
Solution Approach 2:
The filtering element is pre-formed from a tape of filtering material into a beaker shape before insertion into the shell. This preliminary forming action simplifies the final assembly process, increases production speed, and reduces the complexity of the welding operation by preparing components in advance.
2Ease of manufacture
If manufacturing complexity is reduced to lower costs, then production simplicity increases, but production rate may decrease
Solution Approach 1:
Multiple operations are merged into integrated stations: the forming means both creates the beaker shape and prepares the filtering element for insertion; the welding means simultaneously secures the filtering element to the shell while the adjusting means positions it. This merging of operations maintains manufacturing simplicity while achieving high production rates through continuous automated processing.
Solution Approach 2:
The conveyor system enables continuous movement of shells through all manufacturing stages without interruption. The forming, welding, and adjusting operations occur continuously as shells pass through each station, eliminating idle time and maintaining high production rates while keeping the overall process simple and rational.
3Productivity
If automated manufacturing is implemented to increase productivity, then production rate increases, but device complexity increases
Solution Approach 1:
The automated plant is segmented into four independent but coordinated stations: conveying, forming, welding, and adjusting. Each station uses relatively simple dedicated equipment for its specific function, avoiding the need for a single complex automated system. This segmentation maintains manageable device complexity while achieving high overall productivity through continuous automated operation.
Solution Approach 2:
The welding means serves multiple functions: it secures the filtering element to the shell, positions the filtering element, and works in coordination with the adjusting means. This multi-functionality reduces the number of separate devices needed, simplifying the overall plant complexity while maintaining high automated productivity.
