Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional temperature sensors are used to monitor temperature changes, then temperature surveillance is achieved, but the registration is delayed due to heat-transfer-related thermal inertia
Solution Approach 1:
The patent applies preliminary action by using prediction models to estimate the end temperature before the conventional sensor actually reaches and measures it. The system calculates predicted temperature values based on current temperature and rate of change, allowing the measurement system to compensate for thermal inertia delays by anticipating future temperature states rather than waiting for the sensor to physically reach equilibrium.
2Measurement precision
If the temperature sensor waits to fully heat up or cool down to determine the end temperature, then accurate temperature measurement is achieved, but the response time becomes unacceptably long for time-critical applications
Solution Approach 1:
The patent replaces the mechanical/physical waiting process of thermal equilibrium with a computational prediction system. Instead of relying on the physical sensor to slowly reach the end temperature through heat transfer, the system uses mathematical models that calculate the predicted end temperature based on current temperature and rate of change, substituting computational processing for physical thermal processes.
3Device complexity
If conventional temperature sensors are used, then simple temperature monitoring is achieved, but temperature compensation is tardy and insufficient for time-critical applications
Solution Approach 1:
The system performs preliminary temperature compensation calculations by predicting the end temperature before the sensor actually reaches it. The prediction model computes the rate of temperature change and uses this to estimate future temperature states, allowing the measurement system to apply compensation in advance rather than waiting for the sensor to physically reach equilibrium.

AI summary
The present invention relates to a method and a device (1) for predicting an end temperature (46) of a temperature change affecting a temperature-sensitive system, such as a sensor system (2). The method comprises the steps of inputting at least one measured temperature value (11) into a first temperature prediction model (30) and into a second temperature prediction model (32), calculating a first predicted temperature (34) based on the first temperature prediction model (30), calculating a second predicted temperature (36) based on the second temperature prediction model (32), and calculating a final predicted temperature (18) from the first predicted temperature (34) and the second predicted temperature (36). The final predicted temperature (18) can be calculated before the end temperature (46) is measurable by a temperature sensor (10). Thereby, limitations caused by heat-transfer-related thermal inertia are mitigated and time delay is minimized. By combining the results of two temperature prediction models (30, 32) into the final predicted temperature (18), the inventive method further can achieve a higher accuracy than a method employing only one of the prediction models. The device (1) comprises means for performing the inventive method. Further, the present invention relates to a sensor system (2) comprising the device (1).
