Active Ice Press with Electric Heaters for Rapid Ice Sculpting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ice-shaping technologies, such as passive ice presses, are cumbersome, time-consuming, and often fail to produce large, uniquely-shaped ice pieces reliably, as they rely on melting and reshaping with solid metal, which is inefficient and requires frequent heating.
Innovation Solution
An active ice press with a mold body and electric heaters that shape an initial ice billet into a sculpted ice nugget, using movable mold segments and conductive thermal engagement to rapidly achieve a predetermined shape, allowing for efficient and repeated use without extensive material requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If passive ice presses with large solid metal pieces are used, then the ice can be reshaped without hand sculpting, but the process remains very time-consuming and requires large amounts of solid metal
Solution Approach 1:
The patent replaces the passive mechanical melting process with an active thermal system using electric heating elements. The heating elements conduct heat through the mold cavity walls to rapidly melt and reshape ice, substituting the slow passive thermal conduction of traditional metal presses with controlled electrical heating.
Solution Approach 2:
The patent changes the thermal parameters of the ice press by introducing controllable heating elements that can rapidly increase the temperature of the mold cavity. This allows the ice reshaping process to be accelerated by controlling the heat transfer rate, transforming a slow passive process into a rapid active process.
2Ease of operation
If passive ice presses are used, then some hand sculpting dangers are reduced, but the desired shape is not always achieved and requires placing the press under hot water between uses
Solution Approach 1:
The patent replaces the unreliable passive thermal process with a controlled active heating system. Electric heating elements provide consistent and reliable heat transfer to the ice, ensuring that the desired shape is always achieved regardless of environmental conditions, eliminating the need for hot water placement between uses.
Solution Approach 2:
The heating elements are designed to rapidly heat the mold cavity and then retain heat sufficiently to complete the reshaping process without external intervention. The system serves itself by maintaining the necessary thermal conditions throughout the ice reshaping process, eliminating the need for user intervention with hot water.
3Shape
If large billets of ice are shaved or sculpted by hand, then large uniquely-shaped ice pieces can be created, but the process is extremely difficult, dangerous, and time-consuming
Solution Approach 1:
The patent replaces manual mechanical sculpting with an active thermal melting process. Electric heating elements conduct heat through the mold cavity to melt and reshape the ice billet into the desired unique shape, eliminating the need for dangerous hand tools while maintaining the ability to create complex ice forms.
Solution Approach 2:
The patent introduces electric heating elements as an intermediary between the user and the ice billet. Instead of directly contact with ice using hand tools, the user activates the heating elements which then mediate the reshaping process, making it safer and easier while achieving the same artistic results.
4Productivity
If active heating elements are used, then ice can be rapidly and reliably shaped, but energy consumption increases
Solution Approach 1:
The patent uses thin-walled mold segments that act as flexible thermal conduits. The thin walls provide low thermal resistance, allowing efficient heat transfer from the heating elements to the ice with minimal energy loss. This enables rapid ice shaping while minimizing the energy required to maintain the heating process.
Solution Approach 2:
The heating elements are designed to provide continuous, controlled heating throughout the ice reshaping process. By maintaining steady-state thermal conditions and avoiding thermal cycling, the system achieves rapid and reliable shaping while minimizing total energy consumption compared to intermittent or excessive heating approaches.
