Refrigerator Door Basket Rail Layout for Full Storage Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigerators with moving baskets face issues of reduced storage space and visible rail exposure, leading to smaller entrance widths and potential damage to goods when accessing the sub storage compartment.
Innovation Solution
A design where the rail supporting the moving basket is embedded within the door dike, minimizing exposure and using a rail cover bracket to conceal the rail, along with a moving frame and supporter system that includes rollers and a lever for easy operation and load support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rail is mounted at the home bar case to support the moving basket, then the moving basket can be vertically moved, but the storage space is reduced and the rail is visibly exposed
Solution Approach 1:
The rail is extracted from the home bar case and repositioned to the door dike, separating the support structure from the storage space. This allows the moving basket to be supported without occupying storage volume, resolving the contradiction between ease of operation and storage space utilization.
Solution Approach 2:
The door dike serves as an intermediary structure that hosts the rail, acting as a mediator between the moving basket and the home bar case. This intermediary placement enables the rail to be hidden from view while still providing the necessary support function.
2Ease of operation
If the rail is mounted at the home bar case, then the moving basket can be supported, but the rail is visibly exposed when the main door is opened
Solution Approach 1:
The rail is extracted from its visible position at the home bar case and relocated to the door dike, which is hidden from view when the main door is closed. This extraction from the visible field resolves the aesthetic concern while preserving the support function.
Solution Approach 2:
Instead of mounting the rail at the visible home bar case, the invention inverts the approach by mounting it at the hidden door dike. This inversion of the mounting location achieves the same functional result while improving aesthetic appearance.
3Shape
If the opening width is decreased to cover the rail, then the rail is not visible, but the goods cannot be completely visible or may be dashed against the entrance
Solution Approach 1:
The rail is extracted from the opening area and relocated to the door dike. This extraction eliminates the need to reduce the opening width, thereby preserving both the aesthetic appearance (by hiding the rail) and the ease of operation (by maintaining full opening width for goods access).
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
This design prevents storage space reduction, maintains a clean aesthetic, ensures easy operation of the moving basket, and enhances durability by providing bending load resistance while allowing easy assembly and disassembly.
Implementation Method 1
The rollers have outer parts formed of an elastic material, and the rollers are elastically deformed when the rollers move along the roller guide
Implementation Method 2
The rollers have outer parts formed of an elastic material, and the rollers are elastically deformed when the rollers move along the roller guide, and the rollers are elastically restored at the roller openings
