Inverting Ice Sphere Mold Assembly for Easy Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ice sphere molds often stick to the frozen ice, making it difficult to remove the ice sphere, requiring users to run water over the mold or the sphere to facilitate removal.
Innovation Solution
The ice mold consists of two detachable assemblies with a liquid-tight seal, featuring flexible silicone rubber receptacles and annular flanges that form a spherical cavity, allowing the receptacle to invert and release the ice sphere easily without the need for water, enabling convenient removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional ice sphere molds are used, then the mold structure is simple, but the ice sphere sticks to the mold making it difficult to remove
Solution Approach 1:
The mold is divided into two separate assemblies (first and second mold assemblies), each with its own base and mold components. This segmentation allows the ice sphere to be formed in sections and facilitates easier removal by enabling the mold to be opened and inverted, solving the sticking problem while maintaining reasonable structural complexity
Solution Approach 2:
The first mold assembly is designed to be inverted after freezing, with the first mold flipping inside out through the aperture. This inversion mechanism changes the orientation of the ice sphere relative to the mold, allowing easy removal without requiring water or complex extraction mechanisms
2Ease of operation
If the mold uses a detachable two-assembly design with flexible receptacles, then the ice sphere can be easily removed, but the device complexity increases
Solution Approach 1:
The first and second molds utilize flexible receptacles made of elastomeric material that can deform and flex. This flexibility enables the molds to be inverted and opened without breaking, allowing the ice sphere to be easily released while keeping the overall device structure relatively simple and manageable
Solution Approach 2:
The first mold is positioned within the aperture of the first base, and the second mold is positioned within the aperture of the second base. The nested arrangement of mold components within the base structures allows for compact storage and easier handling, reducing the practical complexity despite the detachable design
3Ease of operation
If conventional molds require running water over the mold for removal, then the sealing requirement is lower, but the ease of operation deteriorates due to inconvenience and safety risks
Solution Approach 1:
The liquid-tight seal is established between the first and second molds before the freezing process begins. By pre-establishing the seal, the system maintains integrity throughout freezing without requiring post-freezing water application, enabling direct inversion and removal while ensuring reliable sealing under frozen conditions

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design allows for easy and efficient removal of the ice sphere from the mold without the need for water, enhancing user convenience and reducing the risk of handling frozen ice.
Implementation Method 1
the receptacle of the first mold is moveable from a first molding position, in which the receptacle of the first mold is positioned within the aperture of the base of the first mold assembly, and a second inverted position

AI summary
An ice mold includes a first mold assembly and a second mold assembly, each including a base with an aperture and a mold attached to the base. Each of the molds includes a receptacle that forms a cavity. The first mold assembly is attached removably to the second mold assembly such that a liquid-tight seal is formed between the molds. When the first mold assembly and the second mold assembly are attached to one another, the cavities of the molds form a molding cavity. When the first mold assembly and the second mold assembly are detached from one another, each of the receptacles is moveable from a first molding position, in which the receptacle is positioned within the respective aperture of the base, and a second inverted position, in which at least a portion of the receptacle of extends outwardly from the aperture.
