Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional sensors are used in climate control systems, then the system structure remains simple, but the temperature and pressure differential measurements are inaccurate
Solution Approach 1:
The patent combines multiple sensing functions (temperature sensing and pressure differential sensing) into a single integrated sensor assembly. The sensor probe integrates a temperature sensor with passageways that communicate with a pressure differential sensor, allowing both measurements to be taken from one device rather than requiring separate sensors.
Solution Approach 2:
The sensor probe serves multiple functions simultaneously: it measures temperature through the integrated temperature sensor, measures pressure differential through the passageway connections to the pressure differential sensor, and provides structural support for both sensing elements. This multi-functional design improves measurement accuracy while managing device complexity.
2Adaptability or versatility
If separate temperature and pressure sensors are used, then the measurement functions are comprehensive, but the system complexity and space requirements increase
Solution Approach 1:
The patent merges separate temperature and pressure sensing functions into a single sensor probe assembly. The probe contains both a temperature sensor and passageways that lead to a pressure differential sensor, consolidating what would traditionally require two separate sensing devices into one integrated unit.
Solution Approach 2:
The temperature sensor is nested within the sensor probe body, and the passageways are integrated within the same probe structure. The pressure differential sensor is positioned to receive input from the passageways, creating a nested arrangement where multiple sensing functions are contained within a single probe assembly rather than requiring separate external components.

AI summary
A sensor probe may include an elongated body and a temperature sensor. The elongated body may include at least one first aperture, a first passageway and a second passageway. The first passageway may be in communication with the first aperture and may extend along a longitudinal axis of the elongated body. The second passageway may be in communication with and may extend from the first passageway. The temperature sensor may be disposed within the first passageway and may include a wire extending through a portion of the first passageway and the second passageway. The wire may include a diameter that is less than a diameter of the first passageway such that the first passageway defines a pressure path around the wire.
