Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional glucometers are used to measure blood glucose levels, then the measurement process is simple and equipment is accessible, but early-stage diabetes cannot be detected because individuals may have normal average blood sugar levels
Solution Approach 1:
The patent combines multiple immunosensors into a single multiplexed device that simultaneously detects multiple autoantibodies (anti-TCG, anti-GAD, anti-IA2) in one test, merging several detection functions into one integrated system that maintains simplicity while improving detection precision
Solution Approach 2:
The multiplexed immunosensor system performs multiple detection functions simultaneously - detecting different types of autoantibodies related to diabetes in a single device, making the system universal for comprehensive diabetes screening without requiring multiple separate tests
2Measurement precision
If commercial early detection kits are used to analyze autoantibody profiles, then comprehensive biomarker analysis is achieved, but the process becomes cumbersome, time-consuming, error-prone, and costly requiring specialized laboratory equipment and expertise
Solution Approach 1:
The immunosensor system is designed to be self-contained with integrated reagents and detection mechanisms that automatically perform the measurement without requiring complex sample preparation or specialized laboratory operations, enabling users to conduct tests independently
Solution Approach 2:
The patent replaces complex mechanical and manual laboratory procedures with an electrochemical detection system that automatically measures autoantibody levels through electrical signals, eliminating the need for manual sample handling and complex laboratory equipment
3Measurement precision
If conventional immunculus testing methods are used, then autoantibody concentration trends can be analyzed, but the response time is long and the process requires skilled labor and specialized equipment
Solution Approach 1:
The patent replaces time-consuming manual immunculus testing methods with an automated electrochemical immunosensor system that provides rapid quantification of autoantibody concentrations, reducing testing time from days to minutes while maintaining measurement precision
Solution Approach 2:
The system changes the detection parameter from gradual trend analysis over months to immediate electrochemical signal measurement, allowing rapid assessment of autoantibody levels and enabling faster diagnostic decisions
4Device complexity
If single parameter detection is used in diabetes screening, then the test is simple and cost-effective, but it is insufficient for early detection of this systemic disease that affects several organs
Solution Approach 1:
The patent merges detection of multiple diabetes-related autoantibodies (anti-TCG, anti-GAD, anti-IA2) into a single multiplexed test, combining several detection functions that assess different aspects of pancreatic beta-cell destruction into one comprehensive evaluation
Solution Approach 2:
The multiplexed immunosensor system performs multiple detection functions simultaneously, making it universal for comprehensive diabetes screening across different disease stages and types, thereby improving reliability without sacrificing operational simplicity
