Drawer-Door Refrigerator Wire Routing for Cable Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing refrigerator designs fail to adequately protect the electric wire cable connected to the control panel on a drawer-type door from damage during the sliding and drawing motion of the freezing chamber door, leading to potential interference and damage.
Innovation Solution
A refrigerator design that includes sliding frames and fixed frames with a receiving space to house the electric wire cable, a guide hole, and a push member to ensure the cable is safely routed and protected, preventing damage by guiding it back into the receiving space during door movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the electric wire cable is routed freely during door sliding, then ease of installation is improved, but the cable is damaged due to interference with surroundings
Solution Approach 1:
A guide hole is provided in the fixed frame through which the electric wire cable passes. This guide hole acts as an intermediary structure that directs the cable along a safe path, preventing it from interfering with surrounding components during door sliding motion while maintaining a relatively simple installation process.
Solution Approach 2:
The electric wire cable is nested within the structure formed by the fixed frame and sliding frame assembly. The cable passes through the guide hole in the fixed frame and is received by the sliding frame, effectively nesting the cable within the mechanical structure to protect it from external damage while allowing door movement.
2Reliability
If the electric wire cable is fixed rigidly, then cable protection is improved, but the cable is damaged due to lack of flexibility during door movement
Solution Approach 1:
The electric wire cable is configured to be flexible rather than rigid, allowing it to dynamically adapt its position during door sliding operations. The cable can bend and move within the space defined by the guide hole and sliding frame, maintaining protection while accommodating the dynamic motion of the door.
Solution Approach 2:
The electric wire cable itself acts as a flexible element that can bend and deform to accommodate door movement. This flexibility allows the cable to follow the motion of the sliding door while remaining protected within the structural boundaries of the guide hole and sliding frame assembly.
3Device complexity
If the cable routing structure is simplified, then device complexity is reduced, but the cable is exposed to damage from surroundings
Solution Approach 1:
The electric wire cable is nested within the structural assembly of the fixed frame and sliding frame. The guide hole in the fixed frame and the receiving space in the sliding frame create a nested pathway that protects the cable from external interference while maintaining a relatively simple overall structure without requiring additional complex protective components.

AI summary
A refrigerator includes a storage chamber having an opening; a drawer type door to open or close the opening; a display positioned at the drawer type door; a first connector provided at a sidewall of the storage chamber; a second connector provided at the drawer type door and being electrically connected to the display; a first frame coupled to an inner wall of the storage chamber, the first frame to cover the first connector; a second frame coupled to the drawer type door, the second frame to support a storage box; and a wire electrically connected between the first connector and the second connector. The first frame has a first accommodating part to accommodate one portion of the wire and the second frame has a second accommodating part to accommodate another portion of the wire.
