Solution Overview
Problem
Existing refrigeration appliances face challenges in efficiently managing and routing power and signal cables within the door, leading to random stacking, reduced spatial utilization, and instability during the foaming process.
Innovation Solution
A cable guiding member is integrated into the refrigeration appliance's door, which is positioned within an accommodating space to guide and fix cables, featuring a guiding portion that extends through a through hole, and is securely fixed to the side or front wall, preventing wobbling and enhancing spatial efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cables are routed freely in the accommodating space, then installation flexibility is improved, but cable positioning becomes random and spatial utilization decreases
Solution Approach 1:
The cable guiding member acts as an intermediary component between the accommodating space and the cables. It provides a structured pathway (guiding portion) that channels cables through the door while maintaining installation flexibility. The guiding member with its fixing portion and guiding portion creates an organized routing system that prevents random cable stacking while preserving ease of installation.
2Ease of manufacture
If cables are routed without guidance, then installation simplicity is maintained, but cable stability during foaming process deteriorates
Solution Approach 1:
The cable guiding member is pre-installed and fixed to the door body before the foaming process. The guiding portion is positioned in advance to define the cable pathway, ensuring cables are properly routed and stabilized before heat insulation material is applied. This preliminary positioning prevents cable displacement during foaming while maintaining assembly simplicity.
3Productivity
If cable guiding member is not fixed, then installation speed is improved, but cable routing stability deteriorates
Solution Approach 1:
The cable guiding member is divided into distinct functional segments: a fixing portion for attachment to the door and a guiding portion for cable routing. This segmentation allows the fixing portion to be rapidly secured to the door structure while the guiding portion maintains cable stability. The modular design enables quick installation without compromising routing stability.

AI summary
The present invention relates to a refrigeration appliance. The refrigeration appliance includes a case body; a door capable of being connected to the case body in a manner of sliding forwards and backwards, the door including a front wall, a rear wall that is disposed at intervals with the front wall, a side wall that connects the front wall and the rear wall, and an accommodating space that is formed by encirclement of the front wall, the rear wall, and the side wall and filled with a heat insulation material; and a power and/or signal transmission apparatus, the rear wall having a through hole for passing through the power and/or signal transmission apparatus, and the power and/or signal transmission apparatus including cables; and the refrigeration appliance further includes a cable guiding member that is located in the accommodating space and used for guiding the cables. According to the present invention, not only the cables can be fixed conveniently and prevented from being stacked randomly in the accommodating space, but also the cable guiding member can guide the cable, and provide conditions for power supply for wiring in the door of the refrigeration appliance.
