Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated assay systems are used to improve productivity, then output per unit time increases, but human or machine errors during preparation, loading, and execution cause reproducibility issues
Solution Approach 1:
The system uses self-identification through barcodes/RFID tags on consumables, automatic data retrieval from databases, and automated verification protocols that eliminate manual intervention. The consumables themselves carry their identification data, enabling the system to automatically verify and track them throughout the assay process without human input.
Solution Approach 2:
The system implements continuous verification feedback loops where consumable identifiers are read, validated against database records, and confirmed before each critical operation. Error detection and correction mechanisms provide immediate feedback when deviations occur, ensuring reproducibility while maintaining high throughput.
2Adaptability or versatility
If manual tracking systems are used to monitor analytical parameters, then flexibility is maintained, but time consumption and error potential increase
Solution Approach 1:
Manual tracking systems are replaced with automated electronic identification and data management. Barcodes, RFID tags, and optical readers automatically capture and transmit consumable information to database systems, eliminating manual data entry and tracking while maintaining full adaptability through programmable verification protocols.
Solution Approach 2:
A centralized database system acts as an intermediary between consumables and the assay system. The database stores all analytical parameters and verification rules, automatically matching consumable identifiers with their corresponding protocols and parameters, thereby reducing manual intervention while preserving flexibility.
3Device complexity
If consumable identification and data management are manual, then system complexity is reduced, but manufacturing precision and measurement accuracy suffer
Solution Approach 1:
Consumables are pre-encoded with identification data (barcodes, RFID tags) during manufacturing. All necessary analytical parameters and verification information are pre-loaded into the database before the assay begins. This preliminary preparation eliminates the need for complex real-time data entry while ensuring consistent, accurate tracking throughout the process.
