Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the probe structure contacts the object to be measured, then temperature measurement can be performed, but heat exchange occurs between the probe and the object, affecting measurement accuracy
Solution Approach 1:
The probe surface is segmented into multiple recessed spaces and concave areas, dividing the continuous contact surface into discrete zones. This segmentation reduces the total heat exchange area between the probe and the measured object, thereby minimizing thermal interference while maintaining measurement capability.
Solution Approach 2:
The probe incorporates localized thermal insulation structures (recessed spaces and concave areas) at specific contact regions. These local modifications create thermal barriers precisely where contact occurs, reducing heat conduction paths without affecting the overall probe functionality or measurement point.
2Measurement precision
If the probe structure is modified with recessed spaces and concave areas, then heat conduction path is reduced, but the device structure becomes more complex
Solution Approach 1:
The probe surface incorporates a porous-like structure with recessed spaces and concave areas that reduce thermal conduction. This approach achieves thermal insulation functionality through geometric configuration rather than requiring separate insulation materials or complex multi-layer constructions, thereby limiting the increase in device complexity.
3Measurement precision
If the heat exchange area is reduced by creating concave areas, then measurement accuracy improves, but the manufacturing process becomes more difficult
Solution Approach 1:
The probe incorporates curved concave areas and recessed spaces instead of sharp angular features. These curved geometries are more amenable to standard manufacturing processes such as molding, machining, or 3D printing, reducing the difficulty of fabrication compared to complex angular or irregular shapes while still achieving the desired heat exchange reduction.

AI summary
A temperature measuring device is configured for measuring a predetermined object by a temperature measurement module. The temperature measuring device includes a device main body having a hollow probe structure. An outer surface of the hollow probe structure has a plurality of recessed spaces recessed therefrom and a plurality of concave areas respectively formed in the recessed spaces. When the hollow probe structure of the device main body directly or indirectly contacts the predetermined object, the recessed spaces of the hollow probe structure are configured to reduce a heat conduction path between the hollow probe structure and the predetermined object. When the hollow probe structure of the device main body directly or indirectly contacts the predetermined object, the concave areas of the hollow probe structure do not contact the predetermined object, so as to reduce a heat exchange area between the hollow probe structure and the predetermined object.
