Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operations are used in cell culture systems, then ease of operation is improved, but reliability deteriorates due to variability and human errors
Solution Approach 1:
The system performs self-evaluation of protocol implementation results and automatically acquires modification information without human intervention. The evaluation unit assesses whether implementation results meet predetermined evaluations, and the control unit automatically modifies protocols based on this evaluation, enabling the system to self-correct and improve reliability while maintaining ease of operation.
Solution Approach 2:
The system implements a feedback mechanism where the evaluation unit continuously monitors protocol implementation results and provides feedback to the control unit. Based on this feedback, the control unit automatically modifies protocols to improve reliability. The system evaluates implementation results against predetermined criteria and uses this feedback loop to eliminate variability and human errors while maintaining operational simplicity.
2Reliability
If automated robot operations are used in cell culture systems, then reliability is improved, but device complexity worsens
Solution Approach 1:
The robot is designed to perform multiple functions including executing protocol operations, the evaluation unit assesses implementation results, and the control unit modifies protocols. This multi-functional design integrates what could be separate complex systems into a single coordinated unit, improving reliability while managing overall device complexity through functional integration.
Solution Approach 2:
The system performs self-evaluation and self-modification of protocols without requiring external complex control systems. The evaluation unit automatically assesses results and the control unit automatically modifies protocols based on predetermined evaluations, reducing the need for additional complex external control mechanisms while maintaining high reliability.
3Device complexity
If manual operations are used in cell culture systems, then device complexity is reduced, but productivity worsens due to time-consuming processes
Solution Approach 1:
The robot executes protocol operations continuously without interruption, and the evaluation unit continuously assesses implementation results. This continuous automated operation eliminates the time-consuming nature of manual operations, significantly improving productivity. The system maintains simplicity by using a straightforward automated execution model without complex intermediate steps.
Solution Approach 2:
The feedback mechanism allows the system to quickly identify and correct issues through automatic evaluation and protocol modification. This rapid feedback loop improves productivity by eliminating the time required for manual assessment and adjustment, while the automated nature of the feedback process keeps device complexity manageable.
4Productivity
If automated robot operations are used in cell culture systems, then productivity is improved, but ease of operation worsens
Solution Approach 1:
The system performs self-evaluation and self-modification without requiring complex user interaction. The evaluation unit automatically assesses results and the control unit automatically modifies protocols, maintaining ease of operation despite high productivity. Users simply need to initiate the process without needing to understand or manage the complex automated evaluation and modification procedures.
Solution Approach 2:
The automatic feedback mechanism handles complex evaluation and protocol modification tasks without requiring user intervention. This maintains ease of operation by eliminating the need for users to manually analyze results or adjust protocols, while the continuous automated feedback loop drives high productivity through rapid iteration and correction.

AI summary
A protocol created in such a format that a series of operations in cell culture are executable by a robot 10 is acquired (S1). The robot 10 is controlled to implement the operations according to the protocol (S2). In order to modify the protocol after the implementation of the operations, modification information on at least one action among basic actions which serve as bases for implementing the operations and is performed on an instrument used by the robot 10 in the operations, and complementary actions which complement the basic actions is acquired (S5). The robot 10 is controlled to produce cells by using the protocol modified based on the modification information (S7).
