Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually measure multiple standard materials to update calibration curves, then quantitative analysis accuracy is maintained, but operator burden increases and errors may occur
Solution Approach 1:
The system enables self-service by automatically reading concentration values from codes on standard material containers and performing calibration curve updates without requiring manual operator intervention. The imaging unit captures code images, the code processing unit decodes them to obtain concentration values, and the controller automatically executes the calibration update, allowing the system to serve itself rather than requiring continuous operator input.
Solution Approach 2:
The patent replaces the mechanical/manual process of reading concentration values and inputting data with an automated optical and computational system. The imaging unit uses optical methods to capture code images, and the code processing unit uses computational algorithms to decode and extract concentration values, substituting the manual mechanical process of reading and data entry with automated technological processes.
2Reliability
If multiple standard materials are measured to update calibration curves, then analysis accuracy is maintained, but time consumption increases
Solution Approach 1:
The system achieves continuous useful action by automating the entire calibration update process. Once the imaging unit captures code images and the code processing unit decodes them, the controller continuously and automatically performs the calibration curve update without interruption or pause for manual data entry, maintaining continuous productive action throughout the calibration process.
Solution Approach 2:
The automated system performs the time-consuming calibration update process independently without requiring operator presence or intervention at each step, allowing the system to service itself and eliminating the time operators would spend on manual data collection and entry tasks.
3Adaptability or versatility
If concentration values are manually input for calibration curves, then flexibility in handling different standard materials is achieved, but input errors may occur
Solution Approach 1:
The system creates accurate copies of concentration value information by reading codes directly from standard material containers. Instead of manual transcription which can introduce errors, the imaging unit captures exact code images and the code processing unit decodes them to obtain precise concentration values, creating faithful digital copies of the original information without human intervention.
Solution Approach 2:
The system implements feedback by automatically verifying and utilizing the decoded concentration values from codes on standard material containers. The controller receives direct feedback from the code processing unit about the actual concentration values, ensuring that the calibration curve is updated with accurate, verified data rather than potentially erroneous manual inputs.
