Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If test strips are used for detecting physiological parameters, then users can measure physiological parameters themselves, but measurement accuracy deteriorates due to ambient temperature variations
Solution Approach 1:
The patent introduces a temperature sensor as an intermediary component that detects the temperature of the test strip. This intermediary measurement enables the system to identify temperature-induced measurement errors and apply appropriate corrections, thereby maintaining measurement accuracy while preserving the ease of self-measurement operation.
Solution Approach 2:
The patent changes the measurement parameters by introducing temperature as an additional measured parameter. By monitoring temperature variations and using pre-established correction relationships between temperature and measurement errors, the system dynamically adjusts the interpretation of physiological parameter measurements to compensate for temperature effects.
2Measurement precision
If temperature compensation is implemented, then measurement accuracy is improved, but device complexity increases due to additional temperature sensor and processing requirements
Solution Approach 1:
The processor in the detection device performs multiple functions: it processes the primary physiological parameter signals from the test strip electrodes and simultaneously processes temperature compensation calculations. By making the processor multi-functional, the patent avoids adding a separate dedicated temperature compensation unit, thereby limiting the increase in device complexity.
Solution Approach 2:
The system uses the temperature sensor to provide self-service temperature compensation. The temperature data obtained from the test strip environment automatically triggers the correction process using pre-stored compensation algorithms, eliminating the need for external calibration or manual adjustment by the user.

AI summary
A method for medical detection implemented in a medical detection device, includes a detection instruction being received by the device, the device detecting a temperature of a test strip and determining a measurement error rate corresponding to the actual temperature of the test strip, a relationship having been established between temperatures and measurement error rates for test strip temperatures. When the medical detection device receives the test strip that carries blood of a user, at least one physiological parameter based on the blood on the test strip is measured, and a measurement value of the at least one physiological parameter is obtained. And the measurement value is compensated according to the measurement error rate, and a correction value of the physiological parameter is thus obtained.
