Solution Overview
Problem
Conventional refrigerators often have level differences and uneven gaps between doors, leading to manufacturing inefficiencies and increased costs due to consumer returns.
Innovation Solution
A refrigerator design featuring adjustable hinges with upper and lower moving parts, adjustment members, and guide surfaces that allow for linear movement in specific directions, enabling the adjustment of door levels and gaps between the left and right doors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional fixed hinges are used to support the door, then the hinge structure is simple, but level differences and uneven gaps between doors occur due to manufacturing tolerances
Solution Approach 1:
The hinge structure incorporates adjustable components that allow the door's position to be dynamically modified after assembly. The adjustment member enables changing the distance between the door and cabinet body, and the guide portion allows linear movement in vertical and horizontal directions, transforming a static fixed hinge into a dynamic adjustable system that compensates for manufacturing variations.
Solution Approach 2:
The invention changes the physical parameters of the hinge system by introducing adjustable distance measurements between the door and cabinet body. Through the adjustment member and guide portions, the vertical and horizontal distances can be independently modified, allowing precise control over door alignment parameters to eliminate level differences and gap inconsistencies.
2Manufacturing precision
If adjustable mechanisms are added to correct door alignment, then door alignment precision improves, but the hinge structure becomes more complex
Solution Approach 1:
The hinge structure is divided into distinct functional segments: the adjustment member for distance control, the guide portion for directional movement, and the connection components. This segmentation allows each element to perform its specific function independently, making the complex adjustment mechanism more manageable and easier to assemble while achieving precise door alignment.

AI summary
A refrigerator includes a cabinet: a door formed to open and close the cabinet; an upper moving part coupled to the door and formed to be moved in a first direction with respect to the cabinet; a lower moving part disposed under the upper moving part, including an upper adjustment member configured to move the upper moving part in the first direction, and guiding the upper moving part to be linearly moved in the first direction; and a fixing part fixed to the cabinet under the lower moving part, including a lower adjustment member configured to move the lower moving part in a second direction perpendicular to the first direction, and guiding the lower moving part to be linearly moved in the second direction.
