Solution Overview
Problem
Existing ice presses do not effectively reduce the surface area to volume ratio of ice, leading to excessive melting and dilution of liquids when used to chill them.
Innovation Solution
An ice-shaping device comprising a base and a cover that cooperate to form a spherical ice mold, with a channel and protrusion system to prevent rotation and direct melted water away from the molding area, utilizing materials with high thermal conductivity for efficient ice shaping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional ice presses are used to create ice from ice blocks, then ice can be formed, but the surface area to volume ratio is not reduced, causing excessive melting and dilution of liquids
Solution Approach 1:
The patent employs spherical or hemispherical molding cavities to shape ice into balls or spheres. This spherical geometry inherently minimizes the surface area to volume ratio compared to conventional cubic or irregular ice shapes, thereby reducing the ice's exposure to ambient heat and minimizing melting and dilution of beverages.
2Ease of operation
If the cover is made movable to allow ice block insertion, then ease of operation is improved, but rotation of the cover may occur during closing, affecting manufacturing precision
Solution Approach 1:
The patent incorporates asymmetric features such as a protrusion on the cover and a corresponding channel or recess on the base. This asymmetric design creates a keyed interface that prevents rotational movement of the cover relative to the base, ensuring precise alignment of the molding cavities while still allowing the cover to be easily inserted and removed.
3Productivity
If the ice press applies sufficient pressure to form spherical ice rapidly, then productivity is improved, but melted water may accumulate in the molding cavity, affecting manufacturing precision
Solution Approach 1:
The patent incorporates drainage channels that extend into the molding cavity to extract and remove melted water during the ice shaping process. This extraction of excess meltwater prevents accumulation and distortion of the forming ice sphere, maintaining high manufacturing precision even under the high pressure conditions required for rapid productivity.

AI summary
An ice-shaping device includes a base having an inside surface and an outside surface. The inside surface defines a first ice molding cavity while the outside surface defines a channel. The ice-shaping device includes a cover having an inside surface and an outside surface. The inside surface defines a second ice molding cavity that cooperates with the first ice molding cavity. The cover includes a protrusion on the inside surface that cooperates with the channel. The cover is movable with respect to the base. When in a closed position, the base is located within an interior space of the cover defined by the inside surface of the cover. As the cover is moved from an open position to the closed position, the protrusion cooperates with the channel providing a physical interference to inhibit rotation of the cover with respect to the base.
