Storage drawer assembly for a refrigerator appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Storage drawers in refrigerator appliances are difficult to access due to space constraints caused by hinged doors, leading to user frustration and dissatisfaction.
Innovation Solution
A storage drawer assembly with a lid assembly that includes a first and second lid, each independently rotatable about an axis parallel to the lateral direction, allowing access to the storage compartment even when only one of the refrigerator doors is open.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a storage drawer is positioned at the bottom of the cabinet, then it provides storage space within the chilled chamber, but it becomes difficult to access when only one door is open due to space constraints
Solution Approach 1:
The lid assembly is divided into a first lid and a second lid that can move independently relative to each other. This segmentation allows one lid to be moved out of the way while the other remains in place, enabling access to the storage drawer even when space is constrained by a closed door.
Solution Approach 2:
The lid assembly transitions from a static closed position to dynamic configurations where the lids can be moved independently. The first lid can be rotated or translated while the second lid remains stationary, providing flexible access paths to the drawer that adapt to the spatial constraints imposed by door positions.
2Ease of operation
If a lid assembly covers the storage drawer, then it protects the stored items, but it obstructs access to the drawer when the refrigerator door is closed
Solution Approach 1:
The lid assembly is segmented into multiple independent lids (first lid and second lid) that can be manipulated separately. This allows selective movement of individual lids to provide access paths through or around the lid assembly without requiring the entire lid structure to be moved.
Solution Approach 2:
The lids are configured to move in multiple dimensions including rotation about an axis and translation along the transverse direction. This multi-dimensional movement capability allows the lids to clear access paths in three-dimensional space, enabling drawer access even when horizontal space is constrained by closed doors.
3Adaptability or versatility
If the lid assembly allows independent movement of lids, then it enables access when space is constrained, but it increases the complexity of the lid mechanism
Solution Approach 1:
The lid assembly is divided into independent first and second lids that can move relative to each other, allowing flexible adaptation to different door configurations. Each lid can be moved independently to create access paths appropriate for the current spatial constraints.
Solution Approach 2:
The lid assembly is designed to perform multiple functions: it can fully cover the drawer for protection, partially open to allow access when one door is closed, or fully open when both doors are open. The same mechanism adapts to different access scenarios without requiring separate mechanisms for each case.

AI summary
A refrigerator appliance may include a cabinet defining a chamber. The refrigerator appliance may include a storage drawer assembly positioned within the chamber. The storage drawer assembly may include a drawer defining a storage compartment. The storage drawer assembly may include a lid assembly positioned above the drawer. The lid assembly may include a cover positioned above the drawer. The cover may include a first side support and a second side support. The storage assembly may include a first lid moveably mated to the cover to selectively permit access to the storage compartment. The storage assembly may include a second lid moveably mated to the cover to selectively permit access to the storage compartment. The first lid and the second lid may define an axis of rotation extending parallel to the lateral direction. The axis of rotation being positioned proximate to a rear of the lid assembly.
