Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional housing design is used for temperature measurement device, then the device structure is simple, but the high-temperature resistance is poor and integration is low
Solution Approach 1:
The housing is designed to serve multiple functions: it protects internal components, acts as a heat dissipation channel, and functions as electrodes for charging the battery unit. This multi-functionality resolves the contradiction by improving high-temperature resistance through active heat management while integrating charging functionality into the housing structure itself, avoiding additional complex components.
Solution Approach 2:
The housing is divided into at least two parts that can respectively act as positive and negative electrodes. This segmentation allows each part to have specialized functions while working together as a unified system, improving both high-temperature resistance through distributed heat dissipation and integration by embedding charging functionality within the housing segments.
2Reliability
If traditional circuit board is used in high-temperature environment, then the device structure is simple, but the circuit board cannot withstand high temperatures
Solution Approach 1:
The housing acts as an intermediary heat dissipation channel between the high-temperature environment and the circuit board. By connecting the housing parts that serve as electrodes with the circuit board, heat is transferred away from the circuit board through the housing structure, protecting it from high temperatures while maintaining a relatively simple overall device structure.
3Reliability
If housing only serves as protection, then the device structure is simple, but the integration is low and high-temperature resistance is poor
Solution Approach 1:
The housing is designed to serve multiple functions: it protects internal components, acts as a heat dissipation channel, and functions as electrodes for charging the battery unit. This multi-functionality resolves the contradiction by improving high-temperature resistance through active heat management while integrating charging functionality into the housing structure itself, avoiding additional complex components.
Solution Approach 2:
The protective housing structure is merged with the heat dissipation system and the charging electrode system. By combining these functions into a single integrated housing design, the device achieves high integration without requiring separate components for protection, heat dissipation, and charging, thus improving reliability while avoiding excessive complexity.
4Reliability
If heat dissipation channel is created by connecting housing parts with circuit board, then the high-temperature resistance is improved, but the device structure becomes more complex
Solution Approach 1:
The housing structure serves as both the protective enclosure and the heat dissipation channel. By making the housing itself the heat dissipation pathway rather than adding separate heat dissipation components, the device achieves effective thermal management while maintaining structural simplicity. The same housing parts that provide mechanical protection also conduct heat away from sensitive components.

Implementation Method 1
the first housing and the second housing respectively act as a first electrode unit and a second electrode unit of the temperature measurement device, and the first electrode unit and the second electrode unit are used to charge the battery unit
Implementation Method 2
The heat from the part of the housing exposed to high temperature air is transferred to another part of the housing inserted into food (such as meat), thereby reducing the temperature of the part of the housing exposed to high temperature air and protecting the circuit board part therein
Implementation Method 3
When the temperature measurement device is inserted into food, the food acts as a thermal isolation to protect the part of the temperature measurement device inserted into the food
