Refrigerator Beam Insert Design for Heavy Door Weight Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerator beams lack sufficient weight capacity and stability, particularly when mounting heavy doors, which can lead to instability and deformation.
Innovation Solution
A refrigerator beam design featuring insert portions that fit into recesses in thermal insulation walls, with a dual fixing mechanism that secures the beam to both inner and outer casings, utilizing reinforcing members and thermal insulation material to enhance strength and stability, and a fastener system for secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a beam is used to bridge thermal insulation walls in a refrigerator, then the structural integrity is improved, but the beam may lack sufficient weight capacity and stability when mounting heavy doors
Solution Approach 1:
The fixing mechanism is divided into two separate mechanisms: a first fixing mechanism that fixes the beam to the inner casing, and a second fixing mechanism that fixes the beam to the outer casing. This segmentation allows each fixing mechanism to independently contribute to the overall stability and weight capacity of the beam structure.
Solution Approach 2:
The first fixing mechanism is positioned within a recess formed in the inner casing, creating a nested structure where the fixing mechanism is housed inside the casing structure. This nesting provides structural support while maintaining a compact design.
2Reliability
If a fixed fixing mechanism is used to secure the beam to thermal insulation walls, then the stability is improved, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The first fixing mechanism is pre-positioned within the recess formed in the inner casing during the manufacturing process. This preliminary action allows the fixing mechanism to be ready for assembly without requiring complex on-site installation procedures, thereby improving both stability and assembly simplicity.
3Strength
If the fixing mechanism is exposed on the refrigerator surface, then the structural support is adequate, but the aesthetic appearance deteriorates
Solution Approach 1:
The first fixing mechanism is nested within a recess formed in the inner casing, which conceals the fixing mechanism from external view. This nesting approach maintains adequate structural support while improving the aesthetic appearance by hiding the fixing components inside the refrigerator structure.

AI summary
A refrigerator includes a cabinet having an inner casing, an outer casing, and a thermal insulation space located between the inner casing and the outer casing and filled with a thermal insulation material, to form a pair of thermal insulation walls disposed opposite to each other. The thermal insulation walls have recesses formed in the inner casing and opened forward. A beam bridges the pair of thermal insulation walls, the beam including insert portions disposed on two ends and respectively inserted into the corresponding recesses. A first fixing mechanism is at least partially located in the recess and fixes the insert portion to the thermal insulation wall, which not only facilitates the assembly of the beam and improves production efficiency, but also is beneficial to improving a weight capacity of the beam.
