Expandable Ice Bucket Structure for Refrigerator Space Trade-Offs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ice buckets for refrigerators/freezers have a fixed, non-adjustable volume, which can limit storage capacity and compromise available space for other items, making them either inconvenient for large ice storage needs or inefficient in terms of space usage.
Innovation Solution
A refrigerator/freezer ice bucket with a dispenser interface and hinged outer walls that can pivot to expand storage capacity, allowing for adjustable storage by slanting upwardly, thereby increasing the volume for ice cubes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the ice bucket is made larger to store more ice cubes, then the storage capacity for ice cubes is improved, but the available space for other items in the refrigerator/freezer unit deteriorates
Solution Approach 1:
The ice bucket employs hinged outer walls that can pivot between a retracted position (parallel to the opposite wall) and an extended position (slanted upwardly away from the opposite wall). This dynamic structure allows the storage capacity to be adjusted based on need, enabling the user to expand the ice bucket when large ice storage is required and retract it when space for other items is prioritized, thus resolving the contradiction between ice storage capacity and available space for other items
Solution Approach 2:
The invention changes the geometric parameters of the ice bucket by allowing the hinged outer walls to pivot, thereby altering the internal volume and shape of the storage space. This parameter change enables the ice bucket to adapt its capacity between a smaller configuration (when space efficiency is needed) and a larger configuration (when maximum ice storage is needed), addressing the trade-off between storage capacity and space utilization
2Area of stationary object
If the ice bucket is made smaller to optimize space for other items, then the available space in the refrigerator/freezer unit is improved, but the storage capacity for ice cubes deteriorates
Solution Approach 1:
The dynamic hinged wall mechanism allows the ice bucket to be configured in a compact state with the hinged outer walls retracted parallel to the opposite wall, optimizing space for other items. When additional ice storage capacity is needed, the same structure can be expanded by pivoting the hinged walls outward, thus providing flexibility to address either priority depending on user needs
3Device complexity
If the ice bucket has a fixed volume to simplify the structure, then the device complexity is reduced, but the adaptability to different storage needs deteriorates
Solution Approach 1:
The introduction of hinged connections between the outer walls and the fixed portion adds mechanical complexity but enables the ice bucket to adapt its volume. The hinge mechanism allows simple pivoting motion that transforms the structure from a static box to a dynamically adjustable container, providing adaptability to different storage needs while maintaining relatively simple construction
Solution Approach 2:
The ice bucket with hinged walls serves multiple functions: it can operate as a compact storage container when the walls are retracted, expand to provide larger capacity when needed, and maintain structural integrity throughout the transformation. This multi-functionality resolves the contradiction by making a single structure capable of adapting to various storage requirements

AI summary
A refrigerator/freezer ice bucket is provided. The ice bucket may include a dispenser interface configured to deliver ice cubes to an ice dispenser upon a request by a user for the ice cubes. The dispenser interface may include a back wall. The ice bucket may further include storage configured to, with the back wall of the dispenser interface, store the ice cubes until the user request. The storage includes a fixed portion and a hinged outer wall. The hinged outer wall is configured to pivot from a position that is parallel to an opposite wall of the fixed portion to a position in which one or more portions of the hinged outer wall are fixed to be slanted upwardly away from the opposite wall of the fixed portion, thereby expanding a capacity of the storage.
