Refrigerator Drawer Wiring Guider for Concealed Flexible Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigerators with drawer-type doors often have exposed lifting mechanisms and wiring, leading to safety concerns and potential malfunctions due to damage from repeated use.
Innovation Solution
A wiring guider system is integrated into the refrigerator, routing electrical connections from the cabinet to the door part, keeping them concealed and preventing exposure, while a mechanical device for elevation is housed within the door part to enhance safety and appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the lifting mechanism and wiring are exposed outside the drawer door, then the structure is simple and easy to manufacture, but safety is compromised and the wiring may be damaged during repeated lifting operations
Solution Approach 1:
The wiring guider is nested within the drawer door structure, with the wiring channel formed inside the door body. The lifting mechanism is integrated into the door structure rather than being externally mounted. This nesting approach protects the wiring and lifting mechanism from external damage while maintaining structural simplicity.
Solution Approach 2:
The wiring guider acts as an intermediary component that provides a protected pathway for electrical wiring between the fixed cabinet and the movable drawer door. This mediator structure prevents direct exposure of wiring to external forces while facilitating reliable electrical connection during repeated door operations.
2Device complexity
If the lifting mechanism is disposed outside the bin, then the structure is simple, but serious limitation in safety occurs due to exposure of the lifting mechanism and wiring
Solution Approach 1:
The lifting mechanism is merged with the drawer door structure, where the driving device is provided in the door part and the wiring guider is integrated into the door body. This merging eliminates the need for separate external mounting structures, reducing overall device complexity while improving safety through integrated protection.
Solution Approach 2:
The lifting mechanism components are nested within the drawer door assembly. The wiring channel is formed inside the door structure, and the lifting mechanism is integrated into the door body, creating a compact nested arrangement that reduces external exposure while maintaining functional simplicity.
3Ease of manufacture
If the wiring is exposed to the outside, then the wiring connection is simple to establish, but the exposed wirings may be damaged during the repeated lifting operation or the withdrawal of the drawer to cause failure or malfunction
Solution Approach 1:
The wiring guider serves as an intermediary protective structure that channels wiring between the fixed cabinet and the movable drawer door. This mediator provides a protected pathway that shields wiring from external forces during repeated door operations, ensuring long-term durability while maintaining straightforward wiring installation.
Solution Approach 2:
The wiring guider incorporates a flexible wiring channel that can accommodate the movement and deformation of the drawer door during repeated operations. This flexible structure protects the wiring from stress and damage while allowing natural movement, enhancing wiring durability without complicating the manufacturing process.

AI summary
Provided is a refrigerator. The refrigerator includes a cabinet that defines a storage chamber, a drawer door that is positioned configured to be inserted into and withdrawn out of the storage chamber, the drawer door including a drawer part configured to provide a storage space and a door part configured to, based on the drawer door being inserted into and withdrawn out of the storage chamber, open and close the storage chamber, respectively, an elevation device provided at the drawer part and configured to elevate the storage space, a driving device provided at the door part and configured to provide a driving force to the elevation device, and a wiring guider provided between a top surface of the storage chamber and a bottom surface of the drawer door, the wiring guider being configured to guide a wiring that provides an electrical connection between the cabinet and the driving device. The wiring guider includes a rotation connection member configured to rotatably couple a first end of the wiring guide to the cabinet, a guide head configured to fixedly couple a second end of the wiring guide to the door part, and a flexible portion configured to connect the rotation connection member to the guide head. The wiring between the cabinet and the driving device sequentially passes through the rotation connection member, the flexible portion, and the guide head.
