Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the sensing element is integrated into the air duct assembly as a single unit, then the structure is more compact, but the assembly complexity and labor costs increase
Solution Approach 1:
The air duct assembly is divided into separate modular components: the first duct housing part, the second duct housing part, and the sensing element. This segmentation allows each component to be manufactured and assembled independently, reducing overall assembly complexity while maintaining a compact final structure.
2Measurement precision
If the sensing element is mounted directly inside the first duct housing part, then the temperature sensing is more accurate, but the mounting safety and cable management become problematic
Solution Approach 1:
The second duct housing part serves as an intermediary component between the first duct housing part and the sensing element. It provides a protected mounting location for the sensing element while maintaining proper positioning for accurate temperature sensing of the cool air flowing through the air duct.
3Ease of repair
If the sensing element is made accessible for easy maintenance, then the ease of repair improves, but the leak-proof structure may be compromised
Solution Approach 1:
The air duct assembly is designed with detachable connections between the first and second duct housing parts, allowing the sensing element to be accessed for maintenance by removing the second housing part. The engagement members and guiding grooves ensure that when reassembled, the leak-proof structure is restored while maintaining ease of repair.

AI summary
A cooling appliance includes a storage compartment for receiving goods to be cooled, and an air duct assembly in fluid communication with the storage compartment. The air duct assembly includes at least one air duct for suctioning the cool air from the storage compartment. A sensing element senses the temperature of the cool air of the storage compartment. The air duct has a first duct housing part with an air suctioning entrance opening through which the cool air enters into the air duct, and an external second duct housing part on which the sensing element is provided. The external second duct housing part is configured to be selectively connected to the first duct housing part.
