Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a temperature sensor is placed near the heater, then temperature sensing capability is improved, but response speed and accuracy deteriorate due to indirect measurement
Solution Approach 1:
The temperature sensor is merged with the heating element by directly seating it on the electrically conductive track pattern. This integration allows the sensor to directly measure the heater temperature without delay, simultaneously achieving high measurement precision and fast response speed
Solution Approach 2:
The electrically conductive track pattern serves as an intermediary that provides both heating function and a mounting platform for the temperature sensor. The sensor seating region on the track pattern enables direct thermal and electrical contact, facilitating accurate and rapid temperature sensing
2Ease of manufacture
If the heater structure is simplified, then manufacturing ease is improved, but temperature sensing capability deteriorates
Solution Approach 1:
The electrically conductive track pattern performs multiple functions: it serves as the heating element, provides structural support, and creates the sensor seating region. This multi-functionality eliminates the need for separate temperature sensing structures, maintaining manufacturing simplicity while enabling accurate temperature measurement
Solution Approach 2:
The heating function and temperature sensing function are merged into a single integrated structure. The temperature sensor is directly mounted on the conductive track pattern, eliminating the need for additional sensing components and simplifying the overall heater construction
