Solution Overview
Problem
Existing refrigerator drawer-type doors face challenges in stable elevation due to eccentric loads, leading to potential deformation and breakage, especially when heavy items are stored, and require complex structures to manage the draw-out distance and prevent collision with other components.
Innovation Solution
The design incorporates a drawer cover with a partition and cover part that can rotate to open a rear space, allowing for efficient use of storage space, and an elevation assembly with a driving device to elevate food or containers, while the drawer cover can slide to partially open the rear space, enhancing user convenience and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drawer-type door is disposed in the lower region of the refrigerator, then the refrigerator can be classified as a standard configuration, but the user has to turn its back to take out items and may feel inconvenient or be injured when items are heavy
Solution Approach 1:
The drawer-type door is configured to be movable between a lowered position (for normal access) and an elevated position (bringer level). This dynamic repositioning allows users to access items at a comfortable height without bending or turning, directly improving ease of operation while maintaining a relatively simple structural implementation through the elevation mechanism
2Device complexity
If force for elevation is substantially applied to a front end of the storage container, then the elevation mechanism can be simplified, but it is difficult to perform stable elevation due to eccentric load and serious deformation and breakage may occur
Solution Approach 1:
A support member is introduced as an intermediary component between the elevation mechanism and the storage container. This support member spans across the storage container to distribute the elevation force from the front end across a wider area, preventing excessive stress concentration and deformation while maintaining the simplicity of the elevation mechanism
Solution Approach 2:
The support member is strategically positioned to provide localized reinforcement at critical stress points during elevation. By concentrating structural support where needed (at the front end and across the container), the system achieves stable elevation without requiring a completely complex redesign of the entire elevation mechanism
3Ease of operation
If the drawer-type door is elevated to bring items to user level, then user convenience is improved, but complex structures are required to manage draw-out distance and prevent collision with other components
Solution Approach 1:
The drawer-type door structure is segmented into multiple functional components: the door body, the storage container, the elevation mechanism, and the support member. This segmentation allows each component to perform its specific function independently, simplifying the overall draw-out structure by avoiding the need for a completely complex integrated mechanism

AI summary
Provided is a refrigerator. The refrigerator includes a cabinet (10) defining a storage space, a door part opening (31) and closing the storage space through insertion/withdrawal thereof and defining an outer appearance of a front surface, a drawer part (32) disposed on a rear surface of the door part (31) and having an opened top surface to define an storage space (11), a drawer cover (80) provided inside the storage space (11) to partition the storage space (11) into a front space (611) and a rear space (612) and cover the rear space (612), and a draw-out rail (33) provided on each of both side surfaces of the drawer part (32) to guide insertion and withdrawal of the drawer part (32) so that the front space (611) is exposed to the outside of the refrigerator. The drawer cover (80) includes a partition part (81) partitioning the storage space into the front space (611) and the rear space (612), a cover part (82) extending from an upper end of the partition part (81) to a rear end of the drawer part (32) to cover a top surface of the rear space (612). The draw-out rail (33) has a maximum withdrawal distance so that at least a portion of the drawer cover (80) is disposed in the storage space.
