Solution Overview

Problem

Conventional refrigerators with a single evaporator for both refrigerating and freezing chambers face challenges in maintaining temperature differences and efficiency due to the placement and design of dampers, which affect the capacity and aesthetics of the refrigerating chamber.

Innovation Solution

The design includes a damper arranged inside the freezing chamber duct, inclined to facilitate condensate water drainage and prevent dew condensation, with a connection duct system that allows for selective opening and closing to control cold air flow between the refrigerating and freezing chambers, ensuring efficient temperature management and increased refrigerating chamber capacity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the damper is arranged inside the refrigerating chamber duct, then the temperature control between chambers is improved, but the refrigerating chamber capacity is reduced and the front surface is not flat

Engineering Contradiction:
Improvetemperature difference between refrigerating and freezing chambersVSAvoidrefrigerating chamber capacity
Core Design Contradiction:
TemperatureVSVolume of moving object

Solution Approach 1:

The damper is extracted from the refrigerating chamber duct and relocated to the freezing chamber duct. This extraction removes the obstruction from the refrigerating chamber space, restoring its full capacity and maintaining a flat front surface, while the damper continues to perform its temperature control function from the new location.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The damper arrangement is moved from one spatial dimension (refrigerating chamber duct) to another dimension (freezing chamber duct). This dimensional relocation allows the damper to maintain its control function while eliminating its negative impact on refrigerating chamber capacity and appearance.

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

2Temperature

If the damper is arranged inside the refrigerating chamber duct, then the temperature control is improved, but the structure becomes complex and aesthetics are compromised

Engineering Contradiction:
Improvetemperature control between chambersVSAvoidduct structure complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The damper is extracted from the complex refrigerating chamber duct structure and placed in the freezing chamber duct. This simplifies the overall duct configuration and eliminates the need for complex accommodations within the refrigerating chamber duct, while maintaining temperature control functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

3Temperature

If the damper is arranged inside the refrigerating chamber duct, then the temperature control is improved, but the front surface flatness and aesthetics are reduced

Engineering Contradiction:
Improvetemperature control between chambersVSAvoidfront surface flatness
Core Design Contradiction:
TemperatureVSShape

Solution Approach 1:

The damper is extracted from the refrigerating chamber duct location that would compromise the front surface flatness. By relocating it to the freezing chamber duct, the front surface can maintain its flat, aesthetically pleasing appearance while the damper continues to control temperature distribution.

Inventive Principle:
Principle #2Taking out (Extraction)
