Solution Overview

Problem

Traditional ice cube maker systems for refrigerators either permanently reduce the usable capacity of the freezer compartment or are overly complex, as they are either mounted inside or integrated into the door.

Innovation Solution

An ice cube maker system comprising a detachable ice cube production device and storage device that can be independently attached and detached from the door, allowing for flexible use of space and easy cleaning, with features like projections and recesses for secure attachment and a lever mechanism for easy ice release.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the ice cube maker is permanently mounted inside the freezer compartment, then the ice production function is ensured, but the usable capacity of the freezer compartment is permanently reduced

Engineering Contradiction:
Improveice production functionVSAvoidusable capacity of freezer compartment
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The ice cube maker is divided into two separate devices: an ice cube production device and an ice cube storage device. Both devices are detachably connectable to the door, allowing flexible configuration. When not in use, the production device can be detached completely, freeing up freezer space, while the storage device can remain mounted for continued ice storage functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The ice cube maker system transitions from a permanent fixed mounting to a dynamic detachable mounting on the door. The production device can be attached when ice production is needed and detached when freezer space is required, making the system adaptable to changing user needs rather than statically occupying space.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the ice cube maker is permanently integrated into the door, then the ice production function is ensured, but the system becomes complex and inflexible

Engineering Contradiction:
Improveice production functionVSAvoidsystem structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system is segmented into separate production and storage devices that can be independently attached and detached from the door. This modular approach simplifies the overall system structure compared to a permanently integrated complex mechanism, as each component is simpler and can be used independently or together.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The door-mounted storage device serves multiple functions: it can store ice cubes when the production device is attached, and it can serve as a door shelf for frozen goods when the production device is detached. This multi-functionality reduces the need for separate components and simplifies the overall system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If the ice cube maker permanently occupies door space, then the ice production function is ensured, but the flexibility of space utilization is reduced

Engineering Contradiction:
Improveice production functionVSAvoidspace utilization flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

By separating the production device from the storage device, the system allows the production device to be detached when not needed, providing flexibility in space utilization. The storage device can remain mounted independently, maintaining ice storage capability while allowing the production area to be used for other purposes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The detachable connection allows the system to dynamically adapt to different space requirements. The production device can be mounted when ice production is needed and removed when freezer space is prioritized, making the system versatile rather than permanently fixed.

Inventive Principle:
Principle #15Dynamics
