Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the temperature sensor is arranged inside the biological sample measuring instrument, then the temperature correction can be performed, but the measured value varies due to internal component temperature affecting the sensor
Solution Approach 1:
The temperature sensor is extracted from the biological sample measuring instrument and placed in a separate temperature information supply instrument. This separation prevents the internal components of the measuring instrument from affecting the temperature sensor, allowing accurate environmental temperature detection while maintaining the ability to correct measured values.
2Device complexity
If the temperature sensor is arranged inside the biological sample measuring instrument, then the device structure is simplified, but the temperature detected is different from the environmental temperature of the reaction portion
Solution Approach 1:
A separate temperature information supply instrument is introduced as an intermediary device. This instrument contains the temperature sensor and provides temperature information to the biological sample measuring instrument, ensuring that the environmental temperature is accurately measured without compromising the overall device structure.
3Power
If internal components generate heat, then the device can operate, but the temperature sensor detects incorrect temperature leading to measurement variation
Solution Approach 1:
The temperature sensor is extracted from the measuring instrument to a separate location where it is not influenced by heat-generating internal components. This allows the device to operate with its internal components while the temperature sensor independently detects the true environmental temperature, ensuring consistent and accurate measured values.
