Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If microscopy and laboratory facilities are used for disease diagnosis, then measurement precision and reliability are improved, but device complexity and infrastructure requirements increase
Solution Approach 1:
The patent extracts the essential diagnostic function from complex laboratory microscopy systems and implements it through simplified electrochemical biosensor strips that can be read by portable devices, eliminating the need for full laboratory infrastructure while maintaining diagnostic capability
Solution Approach 2:
The patent replaces the mechanical/optical microscopy system with an electrochemical sensing system that uses electrical signals to detect disease markers, substituting complex optical mechanics with simpler electrochemical measurements that can be performed portably
2Measurement precision
If blood samples are transported to laboratories for analysis, then measurement precision is improved, but loss of time and productivity decrease
Solution Approach 1:
The patent enables the diagnostic system to perform all testing functions at the point of care using portable devices and disposable biosensor strips, eliminating the need to transport samples to external laboratories and allowing immediate local analysis
Solution Approach 2:
The patent uses pre-prepared biosensor strips with embedded reagents and detection elements that are ready for immediate use, eliminating the need for sample preparation and processing steps that would delay results while maintaining diagnostic accuracy
3Measurement precision
If trained microscopists and laboratory personnel are used, then measurement precision and reliability are improved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent designs the diagnostic system to be self-operating with automated sample processing and result interpretation through the portable reader device, eliminating the need for trained microscopists to manually examine samples while maintaining diagnostic quality through embedded algorithms
Solution Approach 2:
The patent uses disposable biosensor strips that are pre-calibrated and single-use, eliminating the need for trained operators to perform complex preparation and analysis procedures, as each strip is designed for simple insertion and automatic reading by the portable device
4Productivity
If rapid diagnostic tests are used for instant results, then productivity and speed are improved, but measurement precision and reliability worsen
Solution Approach 1:
The patent merges the speed advantages of rapid diagnostic tests with the precision of laboratory-quality electrochemical sensing by integrating biosensor technology with a portable automated reader that provides both rapid results and high measurement accuracy through controlled electrochemical detection
Solution Approach 2:
The patent optimizes the electrochemical detection parameters including signal amplification, noise filtering, and calibration algorithms to achieve both rapid measurement completion and high precision in disease marker detection, balancing speed and accuracy through parameter optimization
