Refrigerator Door Hinge Height Adjustment for Door Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In refrigerators with side-by-side compartments, the doors often differ in height due to size discrepancies, requiring a structure to match their heights during assembly, which complicates the assembly process and user convenience.
Innovation Solution
A height adjustment mechanism using a support bracket, door bracket, fixing part, and adjustment part allows the door to be vertically moved by rotating the adjustment part, enabling the doors to be aligned to the same height without manual insertion of hands between the door and support bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a structure is added to match door heights, then door height alignment is improved, but device complexity increases
Solution Approach 1:
The hinge assembly incorporates an adjustable mechanism that allows the door bracket to be moved vertically relative to the support bracket. This dynamic adjustment capability enables precise door height alignment while using a relatively simple structure consisting of a support bracket, door bracket, and adjustment mechanism with fixing parts.
2Ease of operation
If manual insertion of hands is required for door adjustment, then ease of operation is worsened, but device complexity is reduced
Solution Approach 1:
The adjustment mechanism serves as an intermediary tool between the user and the door bracket. By providing a dedicated adjustment mechanism with fixing parts, the system allows users to adjust door height without inserting hands into dangerous gaps, thereby improving ease of operation and safety while maintaining structural simplicity.
3Ease of manufacture
If the adjustment mechanism is simplified, then ease of manufacture is improved, but manufacturing precision of door alignment deteriorates
Solution Approach 1:
The hinge assembly is segmented into distinct components: a support bracket fixed to the door, a separate door bracket, and an adjustment mechanism with fixing parts. This segmentation allows for simple manufacturing of individual components while enabling precise door height alignment through the adjustable connection between components during assembly.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mechanism simplifies the adjustment of door heights, ensuring both doors are at the same level, enhancing user convenience and preventing hand injury by eliminating the need to insert hands between the door and support bracket.
Implementation Method 1
an adjustment part coupled to the fixing part and supporting the door bracket to adjust a vertical movement of the door

AI summary
A refrigerator is provided. The refrigerator includes a body, a door, a support bracket, a door bracket, a fixing part, and an adjustment part. The body defines a storage chamber. The door opens and closes the storage chamber. The door is rotatably coupled to the body by a hinge. The support bracket supports a load of the door. The door bracket is coupled to a lower side of the door. The fixing part is disposed between the support bracket and the door bracket. The adjustment part is coupled to the fixing part and supports the door bracket to adjust a vertical movement of the door.
