Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the temperature sensor is positioned outside the refrigerating cylinder, then the device structure is simple, but the temperature measurement precision of the material is poor
Solution Approach 1:
The temperature sensor is embedded within the refrigerating cylinder, with its sensing end positioned inside the cylinder to directly contact the material, while the connecting end extends outside for electrical connection. This nested configuration allows the sensor to be integrated into the refrigerating system without requiring a separate external mounting structure, thereby improving measurement precision while maintaining structural simplicity.
Solution Approach 2:
The temperature sensor acts as an intermediary element that bridges the refrigerating cylinder interior and the external control system. By positioning the sensing end inside the cylinder, it serves as a mediator to directly measure the material temperature, while the connecting end facilitates the transmission of temperature data to the electrical control assembly for processing and control decisions.
2Manufacturing precision
If the temperature sensor is positioned outside the refrigerating cylinder, then the installation is easy, but the temperature feedback control accuracy is poor
Solution Approach 1:
The temperature sensor is nested within the refrigerating cylinder structure, allowing it to be installed during the manufacturing process rather than requiring separate installation steps. The sensing end is positioned inside the cylinder to directly measure material temperature, while the connecting end extends outside for electrical connection, achieving both accurate temperature feedback control and ease of manufacture.
3Measurement precision
If the sensing end is protruded from the inner wall of the refrigerating cylinder, then the temperature detection is direct, but the stirring paddle may scrape and damage the temperature sensor
Solution Approach 1:
The sensing end of the temperature sensor is designed with a curved surface that matches the curvature of the refrigerating cylinder's inner wall. This curved configuration allows the sensing end to be flush with or slightly recessed from the inner wall, preventing the stirring paddle from scraping or damaging the sensor while still maintaining direct contact with the material for accurate temperature detection.
Solution Approach 2:
The temperature sensor is designed with different geometric characteristics at different locations: the sensing end has a curved surface optimized for contacting the material and avoiding damage, while the connecting end has a straight configuration for electrical connection. This local differentiation of geometric quality allows the sensor to fulfill both measurement and protection requirements simultaneously.
4Reliability
If the sensing end is recessed in the inner wall of the refrigerating cylinder, then the temperature sensor is protected, but material remains at the sensing end increasing cleaning difficulty
Solution Approach 1:
The sensing end is designed with a curved surface that is flush with or slightly recessed from the refrigerating cylinder's inner wall. This curved configuration prevents material from accumulating in recesses while still providing protection for the sensor. The smooth curved surface allows material to be easily wiped or scraped off during cleaning, maintaining both sensor protection and cleaning ease.
