Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual methods are used for measuring glycated hemoglobin, then operational flexibility is maintained, but measurement accuracy and reliability deteriorate due to human errors
Solution Approach 1:
The system performs self-service through automated chemical treatment and measurement processes. The cartridge automatically mixes chemicals with blood samples, and the driver automatically transports and processes multiple cartridges through the rotating tray, eliminating manual intervention and reducing human error while maintaining operational simplicity for the user.
Solution Approach 2:
Manual mechanical operations are replaced with an automated mechanical system. The driver with movable nozzle replaces manual pipetting and chemical handling, while the rotating tray automates the positioning and processing of multiple cartridges, thereby improving measurement precision without significantly increasing user operational complexity.
2Productivity
If automated chemical treatment is implemented, then productivity and measurement speed improve, but device complexity increases
Solution Approach 1:
The automated system is segmented into modular components: individual cartridges containing pre-measured chemicals, a rotating tray for organized processing, and a driver with nozzle for automated liquid handling. This segmentation allows the system to achieve high productivity through automation while managing complexity by dividing functions into independent, replaceable modules.
Solution Approach 2:
The driver with movable nozzle serves multiple functions: it transports blood samples, adds chemicals, mixes solutions, and removes processed samples. The rotating tray simultaneously holds multiple cartridges and positions them for processing. This multi-functionality increases productivity without proportionally increasing overall system complexity.
3Reliability
If information patterns like barcodes are incorporated, then measurement reliability improves by minimizing errors, but device complexity and manufacturing cost increase
Solution Approach 1:
Information patterns such as barcodes or QR codes on cartridges provide feedback to the system about cartridge identity, chemical contents, and processing requirements. This automated information exchange improves reliability by preventing mismatches and errors in chemical selection and processing parameters, while the simplicity of barcode technology keeps the added complexity minimal.
