Mullion Storage Compartment for Higher Refrigerator Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerators do not effectively utilize the space between refrigerated compartments, known as the mullion wall, for storage, limiting storage capacity and accessibility.
Innovation Solution
A storage compartment is integrated into the mullion wall, accessible through a selectively closeable lid, allowing for additional storage space between refrigerated compartments, which can be configured to maintain different temperatures and visibility options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the mullion wall space is left empty or used for structural purposes only, then the structural integrity of the refrigerator is maintained, but the storage capacity is reduced
Solution Approach 1:
The patent merges the structural function of the mullion wall with the storage function by integrating a storage compartment within the mullion wall structure. The mullion wall serves dual purposes: providing structural support between compartments and creating additional storage space, thereby eliminating the trade-off between structural integrity and storage capacity.
Solution Approach 2:
The invention utilizes the previously unused vertical and lateral space within the mullion wall structure to create a new storage dimension. By exploiting the three-dimensional space within the wall itself rather than only the main compartment volumes, additional storage is achieved without compromising the structural framework.
2Quantity of substance
If a storage compartment is added to the mullion wall, then the storage capacity is increased, but the device complexity increases
Solution Approach 1:
The mullion wall is designed to serve multiple functions simultaneously: structural support, thermal insulation, and storage compartment housing. This multi-functionality reduces the need for separate components and simplifies the overall device architecture while maximizing storage capacity.
Solution Approach 2:
The storage compartment is nested within the mullion wall structure, with the lid mechanism integrated into the wall assembly. This nesting approach allows the storage function to be embedded within the existing structural framework, minimizing additional complexity while maximizing space utilization.
3Quantity of substance
If the mullion wall is made thicker to accommodate a storage compartment, then the storage capacity is increased, but the space for other compartments is reduced
Solution Approach 1:
The mullion wall is designed with non-uniform thickness and internal configuration, with the storage compartment located in specific regions where space can be allocated without significantly impacting the overall compartment volumes. The wall structure is optimized locally to provide storage while maintaining adequate space in the main compartments.

AI summary
A compartment for storing items in a mullion wall separating refrigerated compartments is provided. One exemplary embodiment provides a refrigerator with a first refrigerated compartment selectively coverable by a first door and a second refrigerated compartment selectively coverable by a second door. A mullion separates the first and second refrigerated compartments. A storage compartment is located in the mullion and separable from the first refrigerated compartment by a selectively closeable lid.
