Refrigerator Door Basket Lift With Concealed Rail Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigerators with moving baskets face issues of reduced storage space due to rail exposure, visibility problems, and damage to door components, as well as difficulties in maintaining a clean design and easy operation.
Innovation Solution
A refrigerator design featuring a moving basket supported by a system of rollers and a rail embedded within the door dike, with a rail cover bracket to conceal the rail and prevent exposure, allowing for vertical movement without compromising storage space or aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rail is mounted at the home bar case to support the moving basket, then the moving basket can be vertically moved, but the rail is visibly exposed and reduces storage space
Solution Approach 1:
The rail is embedded within the door dike structure, nesting the support mechanism inside the existing door framework. This allows the rail to function while being concealed, eliminating visual exposure and preventing reduction of storage space.
Solution Approach 2:
A rail cover bracket is introduced as an intermediary component that covers the rail. The bracket is disposed between the rail and the storage compartment, serving as a mediator that conceals the rail while allowing the moving basket to pass through and function.
2Shape
If the rail is covered to prevent exposure, then aesthetics are improved, but the horizontal width of the opening is decreased
Solution Approach 1:
The rail cover bracket extends in the horizontal direction rather than vertically covering the rail. By disposing the bracket between the rail and storage compartment horizontally, the solution maintains opening width while achieving aesthetic coverage.
3Adaptability or versatility
If the moving basket is mounted at the home bar case, then additional storage function is provided, but the entire space of the storage compartment is reduced
Solution Approach 1:
The moving basket is integrated into the door assembly rather than occupying space within the storage compartment. This segmentation places the additional storage function in a separate location (the door), preserving the main storage compartment volume.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances storage space utilization, maintains a clean and aesthetically pleasing design, and facilitates easy operation and assembly of the moving basket, while providing improved durability and bending load resistance.
Implementation Method 1
a roller guide capable of vertically moving the rollers
Implementation Method 2
The outer parts of the rollers are formed of an elastic material, and the rollers are elastically deformed when the rollers move along the roller guide
Implementation Method 3
The outer parts of the rollers are formed of an elastic material, and the rollers are elastically deformed when the rollers move along the roller guide
