Reversible Bin Assembly for Refrigerator Drawer Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerator storage drawer assemblies are less accessible and versatile, leading to food waste due to the need to fully extend drawers for content visibility, limiting their use for various food items.
Innovation Solution
A storage drawer assembly with carrier drawers that can be extended or retracted, featuring bins that can be reversibly mounted in either orientation, allowing partial enclosure or full access, enhancing accessibility and versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If drawer assembly is configured as conventional single-function storage, then structural simplicity is maintained, but accessibility and visibility of stored items deteriorate
Solution Approach 1:
The drawer assembly is segmented into multiple functional components: a carrier drawer for general storage and removable bins for specialized storage. This segmentation allows each component to be optimized independently - the carrier drawer provides basic accessibility while bins add specialized functionality without requiring the entire drawer structure to be complex.
Solution Approach 2:
The bin assembly is designed to be dynamically configurable - bins can be removed from the carrier drawer entirely or repositioned. This dynamic capability allows the storage system to adapt to different user needs without permanent structural modifications, improving accessibility for different food types while maintaining relatively simple overall structure.
2Adaptability or versatility
If drawer assembly provides single-function storage configuration, then manufacturing cost is reduced, but versatility for storing various food items deteriorates
Solution Approach 1:
The carrier drawer is designed as a universal base structure that can accommodate multiple different bin types and configurations. The same carrier drawer can store produce bins, deli bins, or serve as general storage, providing multi-functionality without requiring multiple specialized drawer structures, thus controlling manufacturing costs while improving versatility.
Solution Approach 2:
The bin assembly nests within the carrier drawer structure, with bins fitting into designated slots in the carrier drawer. This nesting arrangement allows the compact storage of multiple functional elements within a single drawer unit, increasing storage versatility without proportionally increasing manufacturing complexity or cost.
3Adaptability or versatility
If bin assembly is fixed in single orientation, then mounting simplicity is maintained, but storage flexibility and accessibility deteriorate
Solution Approach 1:
The bin and carrier drawer are designed with asymmetric complementary features - protrusions on bins fit into corresponding recesses in the carrier drawer at specific angles. This asymmetric design enables selective orientation mounting where bins can be installed in different orientations (e.g., front-facing or side-facing) while maintaining secure attachment, providing storage flexibility without requiring complex adjustable mounting mechanisms.

AI summary
A refrigerator appliance includes a storage compartment having a storage drawer assembly disposed therein. The storage drawer assembly includes a carrier drawer, a lid, and a bin that may be reversibly mounted in the carrier drawer in either a first orientation or in a second orientation. The bin defines a storage space for receiving food items. The bin includes a sealing wall that encloses the storage space in the first orientation. The bin defines an access opening that grants access to the storage space in the second orientation.
