Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the temperature sensor is arranged inside the biological sample measuring instrument, then the device structure is simplified, but the measured value varies due to internal temperature fluctuations affecting the temperature sensor

Engineering Contradiction:

Improvedevice structureVSAvoidmeasured value

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The temperature sensor is extracted from inside the measuring instrument and placed outside in the holder. This separates the temperature measurement function from the instrument body, allowing the temperature sensor to measure only the environmental temperature without being affected by internal heat sources, thereby resolving the contradiction between structural simplicity and measurement precision

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The holder serves as an intermediary component that houses both the temperature sensor and the measuring instrument. This intermediary structure enables thermal isolation between the environment and the instrument while providing a platform for temperature measurement, thus maintaining structural simplicity while improving measurement accuracy

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the temperature sensor is arranged inside the biological sample measuring instrument, then the temperature correction can be performed internally, but the temperature detected is different from the environmental temperature of the reaction portion

Engineering Contradiction:

Improvetemperature correctionVSAvoidenvironmental temperature detection

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The temperature sensor is extracted from the instrument interior to the holder exterior, enabling it to detect the true environmental temperature that affects the biological sample reaction, while the instrument retains its temperature correction capability through received temperature data

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system implements feedback by having the holder transmit the detected environmental temperature to the measuring instrument, which then uses this temperature information to correct the measured values, ensuring accurate temperature compensation based on actual environmental conditions

Inventive Principle:

Principle #23Feedback
