Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single temperature sensor is used for air conditioning control, then the device complexity is reduced, but the reliability of temperature measurement deteriorates when the sensor malfunctions
Solution Approach 1:
The patent divides the temperature sensing function into multiple independent sensors (first temperature sensor and second temperature sensor) positioned at different locations. This segmentation allows the system to detect temperature from multiple perspectives, improving reliability when one sensor malfunctions by using data from the other sensor.
Solution Approach 2:
The patent implements preliminary detection of sensor abnormality by comparing temperature detection values from multiple sensors before air conditioning operation begins. This preliminary action identifies malfunctioning sensors in advance, allowing the system to switch to using only healthy sensors and maintain reliable temperature measurement.
2Reliability
If multiple temperature sensors are deployed to improve measurement reliability, then the reliability of temperature measurement improves, but the device complexity increases
Solution Approach 1:
The patent performs preliminary detection of sensor abnormality by comparing temperature detection values from multiple sensors before air conditioning operation begins. This preliminary action identifies malfunctioning sensors in advance, allowing the system to switch to using only healthy sensors and maintain reliable temperature measurement without requiring complex real-time monitoring systems.
Solution Approach 2:
The system automatically detects sensor abnormalities and performs self-correction by switching to healthy sensors without requiring external intervention. The control unit autonomously compares sensor readings, identifies malfunctioning sensors, and adjusts the air conditioning control strategy accordingly, reducing the need for complex manual monitoring and maintenance systems.
3Manufacturing precision
If temperature sensor readings are not verified for abnormality, then the ease of operation is maintained, but the air conditioning performance deteriorates due to inaccurate temperature data
Solution Approach 1:
The patent performs preliminary detection of sensor abnormality by comparing temperature detection values from multiple sensors before air conditioning operation begins. This preliminary verification ensures accurate temperature data is used for control, while the automated nature of the comparison keeps the control system simple and easy to operate.
Solution Approach 2:
The system implements feedback by continuously monitoring temperature detection values from multiple sensors and comparing them to identify abnormalities. This feedback mechanism ensures accurate temperature measurement for air conditioning control while maintaining simplicity through automated comparison and switching logic that requires no complex user intervention.
