Refrigerator Door Ice Dispenser With Integrated Crushing and Shaving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ice dispensing systems in refrigerators consume significant space and hinder user access due to the positioning of ice storage containers and crushing mechanisms within the freezer or fresh food compartments, making it inconvenient for ice access and storage.
Innovation Solution
An ice dispensing assembly that includes a rotatable cylinder with blades for crushing ice and a control plate for shaving, allowing for the positioning of the ice storage container and crushing mechanism on the refrigerator door, providing options for whole, crushed, or shaved ice while optimizing space and access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the ice storage container and crushing mechanism are positioned within the freezer or fresh food compartments, then the ice dispensing function is integrated, but the space for food storage is reduced and user access to compartments is hindered
Solution Approach 1:
The ice storage container and crushing mechanism are extracted from the freezer/fresh food compartments and relocated to the refrigerator door. This separation allows the door to serve dual purposes: providing access to the refrigerator compartments while housing the ice dispensing system, thereby preserving food storage space and improving user access convenience.
2Adaptability or versatility
If the ice storage container and crushing mechanism are positioned within the freezer or fresh food compartments, then the ice dispensing function is integrated, but user access to portions of the compartment and ice storage container is inconvenient
Solution Approach 1:
The ice storage container is extracted and mounted on the door, making it externally accessible. Users can access and clean the ice container without opening the freezer or fresh food compartments, significantly improving ease of operation and maintenance.
Solution Approach 2:
The door serves as an intermediary structure that houses the ice dispensing system separately from the food storage compartments. This intermediary positioning allows independent access to the ice container while maintaining normal access to food compartments, resolving the accessibility conflict.
3Productivity
If conventional ice crushing mechanisms with rotating blades and shafts are used, then ice can be crushed, but the mechanisms consume additional space
Solution Approach 1:
The crushing mechanism is merged with the ice storage container structure. The container itself is designed to incorporate the crushing elements, eliminating the need for separate crushing components and reducing the overall space required for the ice dispensing system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables efficient use of space by integrating the ice dispensing system on the refrigerator door, enhancing user access and convenience by providing multiple ice options without compromising storage space within the compartments.
Implementation Method 1
the first plurality of teeth is configured to contact and crush ice against the second plurality of teeth when the rotatable blade rotates in the first direction
Implementation Method 2
the rotatable blade is configured to rotate in a second direction opposite the first direction to move whole ice from the storage container through the opening
Data Source
AI summary
An ice dispensing assembly that can provide whole, crushed, or shaved ice is described. Rotating blades are carried by a cylinder while locking blades are positioned on a shaft within the cylinder. The cylinder can rotate in different directions to provide whole ice or crushed ice. A control plate can be used to position a shaving blade so as to provide for shaved ice as well.
