Modular Door Storage Bin Assembly with Adjustable Rail Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerator door storage bin systems do not fully utilize available space, as they often lack sufficient structural support for multiple bins of varying sizes and shapes, failing to accommodate changing storage needs due to different item sizes and seasonal or dietary requirements.
Innovation Solution
A modular and customizable Flex-store door storage bin assembly system featuring adjustable and detachable rails with snap-fit mounting structures, allowing bins to slide laterally along the rails, providing flexible storage solutions for different items and maximizing space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed door bin systems are used, then the structure is simple and easy to manufacture, but the storage space cannot be fully utilized and cannot accommodate changing storage needs
Solution Approach 1:
The door storage system is divided into multiple independent rails that can be separately positioned and adjusted. Each rail can hold different bins, allowing the system to be segmented and reconfigured based on storage needs rather than being a fixed monolithic structure.
Solution Approach 2:
The rails are made adjustable and repositionable along the door, transforming the static fixed bin system into a dynamic one where users can change rail positions and configurations to accommodate varying storage requirements over time.
2Adaptability or versatility
If multiple bins of varying sizes are supported, then storage versatility improves, but the structural support requirement increases complexity
Solution Approach 1:
The rail system is designed with universal mounting structures that can accommodate multiple bin sizes and configurations. The same rail structure supports various bin types through standardized attachment points, providing multi-functionality without requiring different structural systems.
Solution Approach 2:
The system adds vertical adjustment capability to the horizontal rail mounting, creating a two-dimensional adjustment system. Mounting structures are spaced vertically along the door height, allowing rails to be positioned at different elevations to optimize support for various bin configurations.
3Adaptability or versatility
If rails are made detachable and adjustable, then storage adaptability increases, but the risk of rail separation under load increases
Solution Approach 1:
The snap-fit mounting structures are designed to engage with the liner panel beforehand, creating a pre-positioned attachment system. The snap-fit mechanism provides immediate mechanical engagement that cushions against accidental detachment under load.
Solution Approach 2:
The snap-fit mounting structures act as intermediaries between the rails and the liner panel. These mounting structures provide a reliable connection interface that mediates the attachment, distributing loads and preventing direct stress on the rail-to-panel connection.

AI summary
A storage system and a refrigeration appliance including the storage system for storing food items in a temperature-controlled environment are provided. The storage system includes at least one rail with at least one elongated main portion extending along the width of the refrigerator door and two support arms on each side of the elongated main portion, and a plurality of detachable storage bins. The two support arms attach the rail to at least one mounting structure of a plurality of mounting structures formed within the liner panel and spaced vertically along the height of the interior of the refrigerator door. The storage bin has an arm extending from a rear surface of the bin and configured to be placed between the rail and the liner panel when the bin is placed in a storage position.
