Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate measuring instruments are used for different detection targets, then detection accuracy is maintained, but device complexity and cost increase
Solution Approach 1:
The patent combines the measuring instrument functions directly into the test strip by integrating a circuit area with electrochemical processing unit, wireless transmission unit, and power source unit. This merging eliminates the need for separate external measuring instruments while maintaining detection accuracy through the integrated detection circuit that directly processes electrochemical signals from the detection area.
Solution Approach 2:
The test strip is designed with universal functionality to detect multiple detection targets through a single device. The circuit area contains general-purpose processing units that can handle different electrochemical detection requirements, allowing the same test strip structure to serve multiple detection purposes without requiring separate specialized instruments for each target.
2Adaptability or versatility
If separate measuring instruments are required for each detection target, then detection functionality is comprehensive, but ease of operation deteriorates
Solution Approach 1:
By merging the measuring instrument functions into the test strip itself, the patent eliminates the need for operators to prepare and match separate measuring instruments with corresponding test strips. The integrated design allows operators to simply use the test strip independently, greatly simplifying the operation process while maintaining comprehensive detection capabilities through the integrated electrochemical processing and wireless transmission units.
3Adaptability or versatility
If multiple measuring instruments are used for multiple detection targets, then detection coverage is complete, but cost increases
Solution Approach 1:
The patent merges multiple instrument functions into a single integrated test strip, eliminating the need to purchase and maintain multiple expensive measuring instruments. The circuit area with its electrochemical processing unit and wireless transmission unit provides complete detection coverage for multiple targets while keeping the overall system cost low, as the test strip itself becomes the measuring instrument.
Solution Approach 2:
The test strip is designed as a disposable low-cost device that integrates previously expensive instrument functions. By making the test strip itself the measuring instrument with integrated circuitry and wireless capabilities, the patent allows users to discard the test strip after use without worrying about maintaining or calibrating expensive permanent instruments, thereby reducing overall detection costs while maintaining complete detection coverage.
4Measurement precision
If separate measuring instruments are used, then detection precision is maintained, but portability deteriorates
Solution Approach 1:
The patent merges the measuring instrument functions into the compact test strip structure, eliminating the need to carry separate heavy measuring instruments. The circuit area with integrated electrochemical processing and wireless transmission units maintains detection precision while the overall device becomes highly portable, as the test strip itself is lightweight and can be used without external equipment.
