Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated computer systems are implemented to manage drug testing parameters and process data, then productivity and speed of analysis are improved, but device complexity increases
Solution Approach 1:
The automated system is divided into distinct functional modules: a user interface application for parameter management, a database for storing testing data, a spectrophotometer for optical measurements, and processing software for calculating activity values. This segmentation allows each component to perform its specific function independently, improving overall system productivity while managing complexity through modular design.
Solution Approach 2:
The computer system integrates multiple functions into a single automated platform: it manages drug testing parameters, controls the spectrophotometer, records optical density measurements, calculates activity values, and displays results. This multi-functionality eliminates the need for separate manual processes for each task, significantly improving productivity in drug effectiveness analysis.
2Loss of time
If manual methods are used for determining drug effectiveness, then device complexity is reduced, but loss of time and productivity decrease
Solution Approach 1:
The automated system performs data processing and analysis without requiring continuous manual intervention. The computer system automatically records optical density measurements at selected time intervals, calculates activity values from the recorded data, and generates correlation displays between activity values and drug effectiveness. This self-service capability dramatically reduces the time required for drug testing while minimizing the need for complex manual operations.
Solution Approach 2:
The system replaces manual mechanical processes with automated electronic and optical systems. Instead of manually recording optical density readings and performing calculations, the system uses a spectrophotometer connected to a computer that automatically measures, records, and processes data. This substitution eliminates time-consuming manual operations while managing complexity through software automation.
3Measurement precision
If automated data processing is implemented, then measurement precision and reliability are improved, but device complexity increases
Solution Approach 1:
The system incorporates automated feedback loops where optical density measurements are continuously recorded and fed back to the processing software. The computer system automatically calculates activity values based on the recorded data and generates correlation displays that provide feedback on drug effectiveness. This automated feedback mechanism ensures consistent and precise measurements while reducing human error in data interpretation.
Solution Approach 2:
The system performs preliminary automated processing of optical density data before final analysis. The computer system automatically records measurements at selected time intervals, pre-calculates activity values from the recorded data, and prepares correlation displays before user interpretation. This preliminary automated action ensures measurement precision is maintained throughout the analysis process while managing complexity through systematic data preparation.

AI summary
A computer system is provided for determining the relative effectiveness of anti-cancer drugs. The interface has selectable options, including an option to manage drug testing parameters, and enables user selection of desired drug testing parameters in relation to a virtual well plate associated with a physical well plate of a spectrophotometer. The computer system causes the spectrophotometer to start a drug test, wherein the physical well plate includes at least one test well containing viable cancer cells; and at least one drug candidate in a predetermined concentration; and at least one control well containing the viable cancer cells alone. The system records the optical density of the well at a predetermined wavelength at selected time intervals for a selected duration of time, and stores the optical density and time measurements in the database. An activity value is calculated from the optical density and time measurements, and a correlation is displayed between the activity value and the drug candidate's ability to induce apoptosis in the cancer cells.
