Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sensing device is positioned near a heat generating device for monitoring, then the monitoring coverage is improved, but the measurement precision deteriorates due to heat interference
Solution Approach 1:
The patent introduces a heat generating device as an intermediary element whose thermal output is measured and used to compensate for measurement errors. By placing a temperature sensor near the heat generating device and measuring its output, the system creates a mediator variable that represents the heat interference, which then allows for mathematical compensation of the environmental parameter measurements.
Solution Approach 2:
The patent changes the measurement parameters by introducing multiple measurement conditions (different power states of the heat generating device). By measuring environmental parameters at different power states (off, low power, high power) and establishing the relationship between power state and measurement deviation, the system enables dynamic parameter adjustment and compensation through calculated correction values.
2Productivity
If environmental parameter measurement is performed near heat generating devices, then real-time monitoring capability is improved, but the reliability of measurement data deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the measured temperature output of the heat generating device is fed back into the measurement system. This feedback information is used to calculate compensation values that are applied to correct the environmental parameter measurements, creating a closed-loop system that continuously adjusts for heat interference based on actual operating conditions.
Solution Approach 2:
The patent performs preliminary measurements at different power states of the heat generating device to establish the relationship between power output and measurement deviation before actual monitoring begins. This preliminary characterization allows the system to pre-calculate compensation factors that can be applied during real-time monitoring, enabling accurate measurements without requiring complex real-time calculations during operation.

AI summary
The present disclosure discloses a method for compensating environmental measurement data. The method may include obtaining a relationship among a deviation of a measured value of an environmental parameter of a first sensing device, an electric power value of a heat generating device, and a power-on duration of a heat generating device, the first sensing device deployed near the heat generating device; obtaining a current electric power value of the heat generating device, a current power-on duration of the heat generating device, and a current measured value of the environmental parameter; determining a current deviation based at least in part on the current electric power value of the heat generating device, the current power-on duration of the heat generating device, and the relationship; and determining a corrected measured value of the environmental parameter based on the current measured value of the environmental parameter and the current deviation.
