Solution Overview

Problem

Existing ice cube production devices have limited capacity and efficiency, as they can only produce a single layer of ice cubes at a time due to slow growth and are not suitable for large-scale production.

Innovation Solution

The device features movable mould halves and heating means to quickly detach and separate ice columns, along with agitation and pre-refrigeration to enhance freezing speed, allowing for interconnected ice cubes to be formed and efficiently packaged in a compact, high-capacity setup.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If water is sprayed against the bottom side of the mould to form ice cubes, then ice cubes can be produced, but the production capacity is limited because only one layer of ice cubes can be made with each batch

Engineering Contradiction:
Improveice cube production capacityVSAvoidnumber of ice cubes per batch
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The invention transitions from producing ice cubes in a single layer (two-dimensional arrangement) to producing multiple stacked layers (three-dimensional arrangement) by providing a mould with multiple水平 spaces arranged vertically. This dimensional change allows simultaneous production of multiple ice cube layers in one batch, directly increasing production capacity without sacrificing individual cube quality

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Manufacturing precision

If the mould is closed during freezing, then clear ice cubes are formed, but the ice cubes are difficult to remove from the mould

Engineering Contradiction:
Improveice cube clarityVSAvoidice cube removal
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The invention applies dynamic vibration to the mould during the freezing process. This vibration serves dual purposes: it prevents air pockets from forming (ensuring clear ice) and simultaneously loosens the ice cubes from the mould walls, making removal easy. The dynamic approach resolves the contradiction by making the mould system responsive rather than static throughout the freezing cycle

Inventive Principle:
Principle #15Dynamics

3Productivity

If the mould remains stationary during freezing, then the structure is simple, but the ice cubes take too long to form and production is slow

Engineering Contradiction:
Improvefreezing speedVSAvoidmould system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The invention introduces vibration capability to the mould system, transforming it from a static to a dynamic structure. This dynamic vibration accelerates heat transfer during freezing, significantly reducing formation time. While this adds some complexity to the mould system, the benefit of faster production cycles results in net productivity improvement

Inventive Principle:
Principle #15Dynamics

4Productivity

If heating means are used to detach the ice column from the mould halves, then ice can be removed very quickly, but the device complexity increases

Engineering Contradiction:
Improveice removal speedVSAvoidmould system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The invention applies vibration during the freezing process itself, which serves as a preliminary action to prevent ice adhesion to the mould walls. This preliminary anti-adhesion measure eliminates or reduces the need for subsequent heating operations to detach the ice, thereby achieving fast removal speed without adding the complexity of heating means

Inventive Principle:
Principle #10Preliminary action

AI summary

The present invention relates to a device and a method for making ice cubes, comprising a supplying device for supplying a liquid substance to at least one elongated mould and a refrigerating device for freezing said liquid substance, which at least one mould defines a space for an ice column which is at least substantially closed at least while said liquid substance is being refrigerated. The at least one mould comprises two mould halves which are movable relative to each other, so that the mould halves can be moved apart once the ice column has been formed. The invention further relates to a method for making ice cubes, comprising the steps of a) supplying a liquid substance to a mould, b) freezing the liquid substance in the mould, and c) removing the ice cubes thus formed from the mould, wherein the liquid substance is supplied in step a) to a mould comprising an at least substantially closed space. The invention further relates to a metering device for ice cubes.
