Solution Overview

Problem

Existing refrigerator designs face challenges in air circulation and temperature distribution within the freezer compartment, which limits the dimensions and positioning of the freezing element, necessitating a gap between the freezing element and the door, thereby restricting the capacity and flexibility of the ice storage system.

Innovation Solution

Incorporating an air flow channel on the freezing element that connects the first and second compartments, allowing for improved air circulation and temperature distribution, eliminating the need for a gap between the freezing element and the door, and enabling more flexible design and positioning of the freezing element.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the freezing element is positioned close to the door to maximize storage capacity, then the ice storage capacity is improved, but the air circulation and temperature distribution in the freezer compartment deteriorates

Engineering Contradiction:
Improveice storage capacityVSAvoidtemperature distribution uniformity
Core Design Contradiction:
Volume of moving objectVSTemperature

Solution Approach 1:

The freezing element is divided into two functional parts: an ice storage compartment for holding ice cubes and a front part containing air flow channels. This segmentation allows the front part to be positioned close to the door for maximum capacity while the air flow channels maintain proper air circulation and temperature distribution in the freezer compartment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Air flow channels are introduced as an intermediary mechanism between the freezing element and the freezer compartment. These channels facilitate proper air circulation and heat exchange, allowing the freezing element to be positioned close to the door without compromising temperature distribution uniformity in the surrounding space.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Temperature

If a gap is maintained between the freezing element and the door for air circulation, then the temperature distribution is improved, but the ice storage capacity is reduced

Engineering Contradiction:
Improvetemperature distribution uniformityVSAvoidice storage capacity
Core Design Contradiction:
TemperatureVSVolume of moving object

Solution Approach 1:

The freezing element is segmented into an ice storage compartment and a front part with air flow channels. This allows the front part to be positioned close to the door (maximizing capacity) while the air flow channels provide the necessary air circulation path without requiring a physical gap.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of maintaining a gap in the horizontal dimension (which reduces storage capacity), the air flow channels provide air circulation paths in vertical and lateral dimensions. This dimensional shift allows the freezing element to occupy maximum horizontal space while air circulation is maintained through alternative pathways.

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

3Volume of moving object

If the freezing element dimensions are increased to hold more ice, then the ice storage capacity is improved, but the positioning flexibility is reduced

Engineering Contradiction:
Improveice storage capacityVSAvoidpositioning flexibility
Core Design Contradiction:
Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The freezing element is divided into a larger ice storage compartment and a front part with air flow channels. This segmentation allows the overall dimensions to be increased for greater capacity while the front part's air flow channels ensure proper air circulation regardless of the element's position, thus maintaining positioning flexibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The front part of the freezing element serves multiple functions: it contains air flow channels for temperature distribution and can be positioned close to the door. This multi-functionality allows the freezing element to have increased dimensions for storage capacity while maintaining adaptability in positioning.

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