Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple heat-generating components are arranged in the heat dissipation compartment, then the heat dissipation function is improved, but the arrangement becomes messy and occupies large space
Solution Approach 1:
The patent combines the heat dissipation fan and condenser into a single integrated assembly that is pre-assembled as one unit. This merging of components reduces the total space required in the heat dissipation compartment while maintaining all necessary heat dissipation functions, directly resolving the contradiction between functional completeness and space efficiency.
Solution Approach 2:
The heat dissipation compartment is divided into distinct functional zones: a first heat dissipation chamber for the fan assembly and a second heat dissipation chamber for the evaporating dish. This segmentation organizes components systematically, preventing messy arrangements while optimizing space utilization for each specific function.
2Reliability
If numerous parts are assembled separately, then the heat dissipation function is improved, but the assembly process becomes complicated and time-consuming
Solution Approach 1:
The heat dissipation fan and condenser are pre-assembled into an integrated unit before installation into the refrigerator. This preliminary assembly action reduces the number of separate assembly steps required during final installation, significantly improving production efficiency while ensuring proper functional integration of heat dissipation components.
3Length of stationary object
If the height of the heat dissipation compartment is reduced, then the refrigerator height is reduced, but the arrangement of components becomes more difficult
Solution Approach 1:
The integrated fan and condenser assembly is designed to utilize the transverse dimension of the heat dissipation compartment effectively. By arranging components along the transverse direction rather than vertically, the design achieves compact height while maintaining adequate space for heat dissipation airflow and component functionality.

Function Achieved in This Case
The design achieves a more compact structure, improved heat dissipation efficiency, and simplified assembly, while reducing the height of the heat dissipation compartment and enhancing electrical safety and user experience.
Implementation Method 1
a heat dissipation fan draws in ambient air from the outside of the refrigerator and induces the air to flow in the heat dissipation compartment, convectively dissipating heat to the condenser and the compressor through convection heat dissipation

AI summary
A refrigerator with a bottom-arranged heat dissipation compartment, comprising: a refrigerator body, a fixing support, a heat dissipation fan, and a condenser. The heat dissipation compartment is arranged behind the bottom of the refrigerator body, the fixing support is arranged in the lateral middle of the heat dissipation compartment to separate the heat dissipation compartment into a first heat dissipation cavity and a second heat dissipation cavity in the lateral direction of the refrigerator body, a fan fixing structure is provided on the side of the fixing support facing the first heat dissipation cavity, and a condenser fixing structure is provided on the side of the fixing support facing the second heat dissipation cavity; the heat dissipation fan is mounted on the fan fixing structure for promoting the formation of a heat dissipation air flow, which enters from the outside of the refrigerator body, blows through the first heat dissipation cavity and the second heat dissipation cavity and is then discharged out of the refrigerator body; and the condenser is mounted on the condenser fixing structure for cooling by means of the heat dissipation air flow. In the refrigerator, the fixing support, the heat dissipation fan, and the condenser together form an integrated air duct structure, components of the heat dissipation compartment are arranged in a more compact structure, and the process of assembling is simpler and more efficient.
