Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an infrared sensor is used to detect thermal images, then background temperature can be sensed, but temperature distribution in the space between the sensor and background cannot be detected
Solution Approach 1:
A temperature sensor is introduced as an intermediary component to detect the temperature of the infrared sensor itself. This additional measurement point serves as a mediator between the background temperature (from infrared sensor) and the unknown temperatures in the space between them, enabling estimation of the temperature distribution through interpolation.
Solution Approach 2:
The temperature sensor creates a physical copy/measurement of the infrared sensor's temperature, which would otherwise be difficult to obtain. This copied temperature value is then used as a reference point to reconstruct the temperature distribution in the space between the infrared sensor and the background.
2Ease of operation
If air conditioner control is based only on background temperature, then simple control is achieved, but accurate temperature control in the space cannot be accomplished
Solution Approach 1:
The control system transitions from considering only a single temperature point (background temperature) to considering multiple temperature dimensions by incorporating the infrared sensor temperature. This creates a temperature gradient model that accounts for vertical temperature variation in the space, improving control accuracy while maintaining computational simplicity through linear interpolation.
