Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cell sheets are cultured in larger culture containers to increase production capacity, then productivity is improved, but manufacturing precision deteriorates due to difficulty in maintaining uniform quality
Solution Approach 1:
The culture container is divided into multiple culture wells, each capable of independently culturing cell sheets. This segmentation allows each well to maintain optimal culture conditions and quality uniformity while the overall system achieves high production capacity through parallel cultivation in multiple wells.
2Manufacturing precision
If manual methods are used to identify and cut high-quality regions in cell sheets, then manufacturing precision can be maintained, but productivity deteriorates due to time-consuming processes
Solution Approach 1:
Manual visual inspection and identification of high-quality regions is replaced by an automated image processing system that captures images of cell sheets, processes them computationally, and identifies suitable cutting positions. This substitution dramatically improves cutting efficiency while maintaining or enhancing quality selection accuracy through objective, standardized analysis.
3Productivity
If automated cutting methods are used to improve productivity, then manufacturing precision deteriorates due to difficulty in accurately identifying cutting positions
Solution Approach 1:
The system uses automated image capture and computer-based image processing to precisely identify cutting positions on cell sheets. The processing unit analyzes image data to determine optimal cutting locations that maintain quality, providing accurate guidance for automated or assisted cutting operations, thereby ensuring both high productivity and manufacturing precision.
4Productivity
If the entire cell sheet is used to maximize material utilization, then productivity is improved, but manufacturing precision deteriorates due to quality variations across different regions
Solution Approach 1:
The system identifies and selects specific high-quality regions within the cell sheet for cutting, rather than using the entire sheet uniformly. By applying local quality assessment through image processing and selecting only suitable regions that meet predetermined standards, the system maintains high quality consistency in the harvested cell sheets while minimizing waste through precise, targeted cutting.

AI summary
A cell sheet cutting assistance system comprises a processor for executing a program and a storage device for storing the program. The processor: receives, as input, an evaluation standard of a cell sheet and quality information of a cultured cell sheet; determines whether the quality information satisfies the evaluation standard; and outputs a cutting position of the cell sheet based on a result of the determination.
