Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the protective shell is designed with a relatively large inner diameter to ensure proper installation of multiple temperature measuring elements, then the installation difficulty is reduced, but the gap between the temperature measuring elements and the inner wall of the shell increases, resulting in low thermal transfer efficiency
Solution Approach 1:
The protective shell is divided into multiple independent channels, each accommodating a temperature measuring element. This segmentation allows each element to be closely positioned within its own channel, eliminating gaps and improving thermal transfer efficiency while maintaining ease of installation through modular channel structures.
Solution Approach 2:
Different regions of the protective shell are designed with different cross-sectional areas. The channels have smaller cross-sectional areas to ensure close contact between temperature measuring elements and the shell wall for high thermal transfer efficiency, while the overall shell structure provides sufficient space for easy installation and maintenance.
2Adaptability or versatility
If multiple temperature measuring elements are installed in the protective shell, then multi-point temperature measurement is achieved, but the elements may shift, interfere with each other, and become entangled, causing temperature signal crosstalk
Solution Approach 1:
The protective shell is divided into multiple independent channels, with each channel accommodating a single temperature measuring element. This segmentation physically isolates each element, preventing shifting, interference, and entanglement between elements, thereby eliminating temperature signal crosstalk while maintaining multi-point measurement capability.
Solution Approach 2:
The channels act as intermediary structures between the temperature measuring elements and the external environment. These channels provide fixed pathways that constrain the elements' positions, preventing mutual interference and signal crosstalk while allowing each element to independently measure temperature at its designated point.
3Adaptability or versatility
If a relatively large inner diameter is used in the protective shell, then multiple temperature measuring elements can be installed, but identifying and replacing faulty components becomes difficult
Solution Approach 1:
The protective shell is segmented into multiple independent channels, each housing a single temperature measuring element. This segmentation allows for easy identification of faulty components by isolating each element in its own channel, and enables straightforward replacement by accessing individual channels without disturbing other elements.
Solution Approach 2:
Each temperature measuring element is extracted into its own dedicated channel, allowing individual elements to be independently accessed, identified, and replaced. This extraction principle enables maintenance personnel to quickly locate and replace faulty components without having to work with a bundled group of elements.
4Adaptability or versatility
If the temperature measuring elements are inserted at a single temperature measurement port with considerable insertion depth, then multi-point measurement is achieved, but the elements may become entangled and cause signal crosstalk
Solution Approach 1:
Instead of inserting multiple elements through a single port, the protective shell is segmented into multiple channels, each providing a separate insertion path for a temperature measuring element. This segmentation prevents entanglement and signal crosstalk while maintaining the ability to measure temperature at multiple points simultaneously.
Solution Approach 2:
The design transitions from a single-dimensional insertion approach (all elements through one port) to a multi-dimensional approach with multiple channels extending in different directions from the connecting base. This dimensional change separates the elements' pathways, preventing entanglement while enabling multi-point measurement.

AI summary
The present disclosure provides a protective shell for a multi-point temperature measuring device and a multi-point temperature measuring device. The protective shell includes: a shell body, with one end connected to a connecting base and the other end extending away from the connecting base. A cross-sectional area of an end of the shell body close to the connecting base is larger than a cross-sectional area of the end of the shell body away from the connecting body; the shell body is provided with a plurality of channels for extending temperature measuring elements; and ends of any two of the plurality of channels away from the connecting base are at different distances from the connecting base. The non-interfering channels ensure proper operation of the temperature measuring elements. The simple structure facilitates disassembly and replacement, enabling accurate and fast temperature detection at different positions.
