Solution Overview
Problem
Existing refrigerators with drawer-type doors face issues such as exposed elevation structures causing safety concerns, poor appearance, and difficulty in separating and installing the elevation mechanism, leading to instability and potential deformation or breakage of the door.
Innovation Solution
A refrigerator design where the drawer-type door portion is elevatable, with components for elevation hidden from view, allowing separation and coupling of the front panel door part and drawer part without additional mechanisms, and power transmission through a connection device, ensuring stable elevation and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drawer-type door is elevated to improve user convenience, then the basket or foods become easier to access, but the connection portion and electrical devices for elevation become exposed causing safety problems
Solution Approach 1:
The elevation structure is nested within the drawer-type door assembly, with the connection portion and electrical devices housed inside the door structure rather than exposed externally. The drawer door itself serves as the housing for these components, eliminating safety hazards while maintaining the elevation function.
Solution Approach 2:
The drawer-type door acts as an intermediary structure that mediates between the elevation mechanism and the external environment. It provides a protective enclosure for the connection portion and electrical devices while still allowing the basket to be elevated through controlled movement of the door assembly.
2Ease of repair
If the elevation structure is made separable to improve service and cleaning management, then maintenance becomes easier, but the structure complexity increases
Solution Approach 1:
The elevation structure is segmented into separable components including the drawer-type door assembly with the basket, and the fixed door structure. This segmentation allows the drawer-type door to be easily removed for service and cleaning while maintaining a relatively simple overall structure through modular design.
3Ease of operation
If the entire basket is elevated to improve accessibility, then the basket becomes easier to reach, but the basket may be severely deformed and damaged due to eccentric load
Solution Approach 1:
Instead of elevating the entire basket uniformly, the elevation mechanism is applied locally to the drawer-type door assembly that contains the basket. This localized approach allows controlled movement while distributing loads more evenly, preventing the severe deformation and damage that would result from elevating the entire basket structure with eccentric loads.
4Ease of operation
If the drawer-type door is withdrawn completely to improve accessibility, then the basket becomes more accessible, but the door and constituents for inserting and withdrawing the door become unstable and prone to deformation or breakage
Solution Approach 1:
The drawer-type door is designed to be partially withdrawn rather than completely removed from the refrigerator body. This partial action provides sufficient accessibility for the basket while maintaining the structural support and stability of the door assembly, preventing deformation or breakage that would occur with complete withdrawal.

AI summary
A refrigerator includes a cabinet, a front panel door part, a drawer part located rearward of the front panel door part, and a connection device that is located at the front panel door part, that is configured to couple the front panel door part with the drawer part, and that is configured to transmit power from the front panel door part to the drawer part. The connection device includes an exposed portion that is exposed through the rear surface of the front panel door part and that allows a user to manipulate the connection device, and the connection device is configured to, based on a manipulation of the exposed portion of the connection device by the user, decouple the front panel door part from the drawer part.
