Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual entry of calibration codes is required, then users can input calibration information, but accuracy decreases and complexity increases due to potential improper entry
Solution Approach 1:
The analyte sensor automatically provides calibration information through machine-readable codes that are read by the analyte meter, eliminating the need for manual user input. The sensor self-identifies its calibration characteristics through the colored codes, allowing the system to automatically retrieve and apply the correct calibration constants without user intervention.
Solution Approach 2:
The manual mechanical process of typing or entering calibration codes is replaced with an optical reading system. The analyte meter uses optical components to automatically detect and read the machine-readable colored codes on the sensor, substituting human manual entry with an automated optical recognition system that eliminates entry errors.
2Loss of information
If manual entry of calibration codes is required, then calibration information can be provided, but time is lost and productivity decreases
Solution Approach 1:
The calibration information is pre-encoded into machine-readable colored codes on the analyte sensor during manufacturing. This preliminary encoding of calibration data allows for instant automatic retrieval during testing, eliminating the time-consuming manual entry process and enabling rapid calibration information transfer that increases testing throughput.
3Extent of automation
If machine-readable colored codes are integrated, then automation and accuracy improve, but device complexity increases
Solution Approach 1:
The patent uses machine-readable colored codes with specific RGB hue combinations to encode calibration information. Different color combinations represent different calibration constants or sensor types. This color-based encoding system provides a compact, visually distinct method for storing multiple calibration parameters that can be easily read optically without requiring complex electronic storage or additional physical components on the sensor.
