Solution Overview

Problem

Conventional refrigerators with ice making compartments face challenges in achieving enhanced cooling performance and have ice making units that are not easily replaceable or repairable, leading to inefficiencies and increased energy loss.

Innovation Solution

A refrigerator design featuring a refrigeration cycle with a refrigerant pipe that includes a fixing member to securely position the pipe within the ice making compartment, allowing for a detachable ice making unit with a drainage duct and fixer to enhance cooling efficiency and facilitate easy replacement or repair.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the refrigerant pipe is fixed inside the ice making compartment, then cooling performance is improved, but maintenance and replacement become difficult

Engineering Contradiction:
Improvecooling performanceVSAvoidmaintenance difficulty
Core Design Contradiction:
TemperatureVSEase of repair

Solution Approach 1:

The refrigerant pipe is divided into two portions: a first portion fixed outside the ice making compartment and a second portion that can be detached. This segmentation allows the pipe to remain stable during operation while enabling easy removal for maintenance, resolving the contradiction between fixed positioning for cooling performance and accessibility for repair.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second portion of the refrigerant pipe is extracted from the ice making compartment, allowing it to be detached from the ice making unit. This extraction enables maintenance personnel to access and replace the pipe portion without disassembling the entire ice making compartment, thus improving ease of repair while maintaining cooling performance through the first fixed portion.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If the ice making unit is permanently installed, then cooling efficiency is maintained, but replacement and repair are complicated

Engineering Contradiction:
Improvecooling efficiencyVSAvoidreplacement ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The ice making unit is designed with dynamic characteristics, allowing it to be detachably coupled to the refrigerant pipe. This means the unit can be securely installed for normal operation to maintain cooling efficiency, but can also be easily removed and replaced when needed, transforming a static permanent installation into a dynamic reversible connection.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The coupling mechanism between the ice making unit and refrigerant pipe is segmented into detachable portions, enabling the unit to be separated into manageable components. This segmentation allows the ice making unit to remain stable during operation while facilitating simple replacement procedures when maintenance is required.

Inventive Principle:
Principle #1Segmentation

3Temperature

If the refrigerant pipe is securely fixed, then cooling performance is enhanced, but assembly complexity increases

Engineering Contradiction:
Improvecooling performanceVSAvoidassembly complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The refrigerant pipe assembly is segmented into a first portion with external fixing and a second portion for detachable coupling. This segmentation simplifies the overall assembly process by allowing the first portion to be installed once and left fixed, while the second portion can be easily connected and disconnected without complex fastening mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The complex fixing mechanism is extracted and replaced with a simpler detachable coupling system. Instead of requiring complex internal fixation within the ice making compartment, the solution uses an external fixing member and a simple detachable connection for the second portion, reducing assembly complexity while maintaining secure positioning for cooling performance.

Inventive Principle:
Principle #2Taking out (Extraction)
