Solution Overview

Problem

Existing ice cube makers are inefficient in providing a continuous supply of ice cubes, often result in cubes sticking together, and require manual handling, which can be unhygienic and space-consuming, with existing solutions failing to address the issue of cube metering and jamming.

Innovation Solution

An apparatus with movable mould parts and a controller to form and disperse ice columns around elongated elements, an ice remover to facilitate continuous ice supply, and an ice breaker to break off ice cubes, allowing for automatic distribution and compact construction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If ice cubes are stored in a large refrigerator with storage compartment, then ice cubes can be stored, but the device occupies large space in the establishment

Engineering Contradiction:
Improveice cube storage capacityVSAvoidrefrigerator size
Core Design Contradiction:
Quantity of substanceVSVolume of stationary object

Solution Approach 1:

The ice storage system is segmented into multiple small moulds arranged in a matrix, each producing individual ice columns. This segmentation allows the system to provide adequate ice storage capacity through continuous production from multiple small units rather than requiring a single large storage compartment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements continuous ice production by having multiple moulds operating in sequence, with conveying means continuously transporting ice columns from moulds to a collection container. This continuous action eliminates the need for large batch storage while maintaining adequate supply.

Inventive Principle:
Principle #20Continuity of useful action

2Ease of operation

If ice cubes are picked up using tongs from storage compartment, then ice cubes can be dispensed, but the ice cubes are continuously exposed to ambient air which may be unhygienic

Engineering Contradiction:
Improveice cube dispensingVSAvoidhygiene contamination
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system employs an automatic dispensing mechanism where conveying means automatically transport ice columns from the moulds through a discharge opening into a container, eliminating the need for manual handling with tongs. This self-service approach keeps ice cubes enclosed throughout the process, preventing exposure to ambient air and maintaining hygiene.

Inventive Principle:
Principle #25Self-service

3Quantity of substance

If ice cubes are stored in container, then ice cubes are available for use, but the ice cubes may stick to each other making it difficult to pick them up

Engineering Contradiction:
Improveice cube availabilityVSAvoidice cube handling
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The system produces ice in segmented form as individual columns from separate moulds, which are then individually conveyed and deposited into the container. This segmentation prevents the ice cubes from sticking together in mass, maintaining ease of handling while ensuring availability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The conveying means operates periodically to transport and deposit ice columns one at a time into the container. This periodic action ensures ice cubes are deposited separately rather than in continuous contact, preventing them from sticking together and maintaining ease of operation.

Inventive Principle:
Principle #19Periodic action

4Ease of operation

If manual metering of ice cubes is used, then number of ice cubes can be controlled, but it is difficult to meter the number of ice cubes accurately

Engineering Contradiction:
Improveice cube meteringVSAvoidice cube quantity control
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system implements automatic metering through the conveying means that transports a predetermined number of ice columns from the moulds to the container. This self-service metering mechanism accurately controls the quantity of ice cubes without requiring manual counting or estimation, achieving both ease of operation and measurement precision.

Inventive Principle:
Principle #25Self-service

5Productivity

If ice cubes are dispensed through discharge opening, then ice cubes can be delivered, but the ice cubes may get jammed in front of or in the discharge opening and block it

Engineering Contradiction:
Improveice cube dispensing rateVSAvoiddischarge opening functionality
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The discharge system is designed to handle ice in segmented form as individual columns conveyed one at a time through the discharge opening. This segmentation prevents multiple ice cubes from accumulating and jamming the opening, maintaining both productivity and reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The conveying means operates periodically to transport ice columns through the discharge opening at controlled intervals. This periodic action prevents ice cubes from accumulating in front of the opening, eliminating jamming while maintaining efficient dispensing rates.

Inventive Principle:
Principle #19Periodic action

AI summary

An apparatus for making ice cubes comprises a plurality of elongated elements (1, 2). A plurality of mould parts (3, 4, 5, 6) are movable with respect to the elongated elements (1, 2). The plurality of mould parts are movable to form a mould (7) around a first elongated element (1) of the elongated elements. A control unit is configured to control a movement of the plurality of mould parts with respect to the elongated elements to move the mould parts (3, 5) forming the mould (7) around the first elongated element (1) apart once a first ice column (201) has been formed in the mould (7), and form a mould (8) around a second elongated element (2) of the elongated elements. An ice remover (202) is configured to remove the first ice column (201).
