Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual deck setup is performed by laboratory technician, then flexibility and adaptability are maintained, but human errors increase leading to unsuccessful automated processes
Solution Approach 1:
The system captures images of the deck setup and provides real-time feedback to the operator through an imaging device and display interface. The processor compares the captured image with the expected protocol configuration and indicates whether each component is correctly placed, allowing immediate correction of errors before the automated process begins.
Solution Approach 2:
The system performs self-verification of deck setup by automatically capturing images, processing them through neural networks or template matching algorithms, and generating verification reports without requiring external inspection. The workstation independently checks its own configuration against the programmed protocol requirements.
2Reliability
If automated verification systems are implemented, then deck setup accuracy improves, but device complexity increases
Solution Approach 1:
The imaging device serves multiple functions: capturing deck setup images, identifying components through image processing, verifying configuration against protocols, and providing visual feedback to operators. The display interface also displays instructions and status information, consolidating multiple system functions into integrated components that reduce overall complexity.
Solution Approach 2:
The system replaces manual visual inspection and physical verification methods with automated image capture and digital processing. Instead of requiring operators to manually check each component's position and configuration, the imaging device and processor automatically perform verification through optical recognition and algorithmic comparison with expected configurations.
3Loss of time
If real-time image processing is performed during deck setup, then error detection speed increases, but processing time and computational resources increase
Solution Approach 1:
The system performs image processing at selective stages rather than continuously monitoring every movement. It captures images at key verification points in the deck setup process and processes them accordingly, performing partial verification actions that are sufficient to detect errors without the excessive computational burden of continuous full-frame analysis.
Solution Approach 2:
The system uses disposable or temporary image data structures and processing models that are created only when needed for verification and then discarded. Instead of maintaining permanent complex data structures or continuously running computational models, the system generates temporary processing artifacts that serve the immediate verification need and are then eliminated, reducing overall computational resource requirements.

AI summary
A laboratory workstation for preparing a sample according to a programmed protocol. The laboratory workstation may include a display device configured to display an instruction for loading a first item of labware onto a deck of the laboratory workstation at a position on the deck specified by the programmed protocol; an imaging device configured to monitor the deck of the laboratory workstation by creating one or more images of the deck; and a processor configured to recognize, in the one or more images created by the imaging device, an item of labware loaded onto the deck by an operator. In some embodiments, the processor may be configured to indicate on the display device whether the recognized item of labware loaded by the operator is arranged on the deck in accordance with the programmed protocol.
