Refrigerator Cooler Board Assembly to Reduce Switch Box Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing refrigerating apparatuses with coolers attached to refrigerant pipes face difficulties in assembling and installing components due to the need for complex attachment processes, including soldering within a switch box, which is time-consuming and challenging, especially when dealing with bulky components and vibrations from the compressor.
Innovation Solution
The cooler is directly attached to the board using a support member, and the board is fixed to the casing without a switch box, allowing for easier assembly and installation by eliminating the need for intricate soldering within a switch box and reducing the risk of excess load on lead lines, while also grounding the cooler for safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the board is attached to the switch box using screws and lead lines are soldered within the switch box, then the assembly is structurally stable, but the assembly process becomes time-consuming and difficult
Solution Approach 1:
The patent removes the switch box from the assembly structure. The board is directly attached to the casing using fixing members, and the cooler is directly attached to the board. This extraction of the intermediate switch box component simplifies the assembly process while maintaining structural stability through direct mounting relationships.
Solution Approach 2:
The patent divides the assembly into distinct functional components: the board is separately fixed to the casing, and the cooler is separately attached to the board. This segmentation allows each component to be assembled independently without requiring complex integration within a switch box, thereby improving assembly efficiency.
2Strength
If the board is attached to the bulky switch box, then the assembly is mechanically supported, but the installation process becomes difficult and time-consuming
Solution Approach 1:
The switch box is completely removed from the assembly. The board is directly fixed to the casing using fixing members that provide mechanical support without requiring the intermediate switch box structure. This eliminates the bulkiness and complexity of installing a large switch box while maintaining adequate mechanical support for the board.
3Stability of the object's composition
If the cooler is attached to the switch box, then vibrations are transmitted to the board through the switch box, but this creates excess load on the lead line
Solution Approach 1:
The switch box is removed from the vibration transmission path. The cooler is directly attached to the board, which is fixed to the casing. This direct attachment path allows vibrations to be transmitted to the board structure itself rather than being funneled through the lead line via the switch box, reducing stress on the electrical connections.
Solution Approach 2:
The board itself acts as an intermediary structure between the cooler and the casing. By directly attaching the cooler to the board, the board absorbs and distributes vibration forces through its rigid structure rather than transmitting concentrated forces to the lead line through the switch box mounting structure.
