Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual or semi-automated methods are used for sample processing, then operator control and flexibility are maintained, but labor intensity increases and operator error becomes more likely
Solution Approach 1:
The system enables self-service operation through automated sample intake, barcode scanning, and processing. Samples are automatically recognized, tracked, and processed through the workflow without requiring manual intervention at each step, reducing operator error while maintaining high automation levels
Solution Approach 2:
The system implements feedback mechanisms through barcode tracking that continuously monitors sample status and provides real-time information about sample location and processing state. This feedback loop ensures accurate sample identification and tracking throughout the automated process, preventing operator errors
2Productivity
If semi-automated systems are used, then some automation is achieved, but pre-processing steps still require manual labor and system complexity increases
Solution Approach 1:
The system employs universal sample containers with standardized barcodes that can accommodate multiple sample types and formats. The single vial design serves multiple functions: sample storage, identification, and processing container, eliminating the need for multiple specialized containers and reducing overall system complexity
Solution Approach 2:
The system segments the sample processing workflow into distinct automated stages: sample intake with barcode scanning, automated processing, and result generation. Each stage is independently automated but integrates seamlessly into the overall workflow, increasing productivity without proportionally increasing complexity
3Adaptability or versatility
If existing automated systems are used, then throughput is increased, but they cannot accept various sample formats and cannot process different sample types simultaneously
Solution Approach 1:
The system uses universal sample containers with barcodes that can identify and accommodate different sample types (urine, blood, tissue, etc.) and formats. The standardized container design with machine-readable codes enables the system to handle diverse samples through a single interface, maintaining high throughput while improving adaptability
Solution Approach 2:
The system changes parameters through barcode identification, where different barcode patterns encode different sample types and required processing protocols. This parameter encoding allows the system to automatically adjust processing parameters based on sample type while maintaining consistent automated handling, thereby supporting both versatility and throughput
4Loss of time
If manual pre-processing steps are required, then sample preparation flexibility is maintained, but processing time increases and productivity decreases
Solution Approach 1:
Samples are pre-labeled with barcodes before entering the system, and the system performs automated sample adequacy assessment and preparation upon intake. This preliminary automated action eliminates the need for manual pre-processing steps later in the workflow, reducing processing time and increasing throughput
Solution Approach 2:
The system maintains continuous automated processing through uninterrupted workflow stages. Samples move continuously from intake through processing without manual intervention pauses, ensuring that the useful action of sample processing occurs without interruption, thereby minimizing processing time and maximizing throughput
