Ice Sphere Mold With Telescoping Alignment and Gravity Shaping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for shaping irregular ice into a uniform sphere are costly to manufacture and cumbersome to use due to the need for guide rods and complex alignment, which interferes with the placement and transformation of ice chunks.
Innovation Solution
A telescoping engagement of mold halves eliminates the need for guide rods, using high heat conductivity materials like aluminum for the mold parts to efficiently melt and reshape ice into a spherical form through gravity and heat transfer, with a simple and cost-effective design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If guide rods and guide openings are used to direct mold halves toward one another, then alignment precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent removes guide rods and guide openings from the mold assembly, extracting the alignment function to a separate base component. The base includes recesses that receive the lower mold half, providing alignment without requiring complex guide mechanisms in the mold halves themselves.
Solution Approach 2:
The base acts as an intermediary component that mediates the alignment between mold halves. Instead of the mold halves directly requiring guide rods and openings for alignment, the base provides the alignment function through its recesses, simplifying the mold design.
2Manufacturing precision
If guide rods are used to direct mold halves, then alignment is improved, but ease of operation deteriorates due to interference with ice chunk placement
Solution Approach 1:
By removing guide rods from the mold assembly and transferring the alignment function to the base, the patent eliminates physical obstructions that would interfere with ice chunk placement. The ice can be freely positioned on the lower mold half without navigating around guide rods.
Solution Approach 2:
The alignment function is segmented from the mold halves and assigned to the base component. This separation allows the mold halves to be simple, open components that do not interfere with ice placement, while the base provides the necessary alignment structure.
3Manufacturing precision
If multiple guide rods and guide openings are used, then alignment precision is improved, but manufacturing cost increases due to guide bushings and complex assembly
Solution Approach 1:
The patent extracts the alignment function from the expensive mold halves and assigns it to a simpler, more cost-effective base component. This eliminates the need for guide bushings and multiple guide rods, significantly reducing manufacturing complexity and cost.
Solution Approach 2:
The base with its alignment recesses serves as a simple, cost-effective alignment mechanism that does not require expensive guide rods or bushings. While the base may need replacement, its simplicity makes it much cheaper than complex guide systems.

AI summary
An ice shaping device with upper and lower mold parts with a mold cavity, the upper mold part being configured to move toward the lower mold part by gravity. The mold parts are formed of a material capable of rapidly conducting heat and together having a mass such that, starting at room temperature, the mold parts possess sufficient transferable heat to melt away portions of an ice chunk blank in contact with the upper and lower mold parts, the upper mold part having sufficient mass to apply a significant amount of pressure, under the force of gravity, to portions of the ice chunk blank in contact with the mold parts. One of the mold parts has a predetermined exterior periphery and the other of the mold parts has an extension configured to substantially surround and slidably receive the external periphery of the first mold part.
