Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a Raman probe is integrated into each bioreactor, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
A single Raman probe is designed to serve multiple bioreactors through automated positioning. The probe can be moved to different bioreactors in the array, allowing one probe to perform the function that would otherwise require multiple probes, thereby reducing system complexity while maintaining measurement capability
Solution Approach 2:
A Cartesian robot serves as an intermediary mechanism between the Raman probe and the bioreactors. The robot enables precise positioning and movement of the probe to access different bioreactors, eliminating the need for direct integration of probes into each bioreactor while maintaining measurement precision
2Ease of operation
If manual sample extraction is used, then ease of operation is improved, but productivity decreases due to time-consuming rinsing
Solution Approach 1:
The system performs self-service through automated sample extraction and analysis. The Cartesian robot automatically positions the probe, extracts samples, and moves between bioreactors without manual intervention, eliminating the need for manual rinsing operations while maintaining ease of operation
Solution Approach 2:
Manual mechanical sample extraction and rinsing operations are replaced with an automated robotic system. The Cartesian robot provides precise, repeatable positioning and sample extraction, replacing the manual mechanical actions with an automated control system that eliminates time-consuming rinsing steps
3Productivity
If automated sample extraction is implemented, then productivity is improved, but reliability decreases due to potential errors
Solution Approach 1:
The system incorporates feedback mechanisms through precise robotic control and positioning. The Cartesian robot uses controlled movement and positioning feedback to ensure accurate sample extraction from each bioreactor, maintaining reliability while achieving automated high-throughput operation
Solution Approach 2:
The system performs preliminary positioning and setup actions through the Cartesian robot before sample extraction. The robot pre-positions the probe at the correct location and orientation, ensuring that the subsequent automated extraction process is reliable and error-free
4Productivity
If multiple bioreactors are analyzed sequentially, then productivity is improved, but loss of time increases due to probe movement
Solution Approach 1:
The system uses dynamic positioning through the Cartesian robot, which can rapidly move the probe between bioreactors along predefined paths. The robotic system optimizes movement trajectories and speeds to minimize repositioning time while maintaining measurement accuracy, enabling efficient sequential analysis of multiple bioreactors

AI summary
A method of performing an optical analysis on multiple vessels using a single optical analysis device includes placing on and in each vessel a protective sheath that will accept a probe head of the optical analysis device. The probe head may be easily inserted into and removed from the protective sheath. A Cartesian robot may move the probe head from vessel to vessel to perform the analyses. The system for the optical analysis include at least two vessels, an optical analyzer, and a Cartesian robot.
