Solution Overview

Problem

Existing refrigerators with built-in water dispensers often protrude or interfere with storage space, making them inconvenient to use and inefficient in terms of space utilization.

Innovation Solution

A dispenser is strategically positioned between receiving members or between a receiving member and the side wall of the refrigerator compartment, allowing for easy access to dispense drinking water without protruding, and the associated components like the water tank, filter, and pump are housed behind the dispenser to optimize space usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a dispenser is installed on the outer surface of the refrigerator door, then water dispensing convenience is improved, but the refrigerator structure becomes more complex and may interfere with door operation

Engineering Contradiction:
Improvewater dispensing convenienceVSAvoidrefrigerator structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The dispenser is extracted from the traditional door-mounted position and relocated to the interior of the refrigerator compartment. Specifically, it is positioned between upper and lower receiving members (shelves or drawers), removing it from the door structure entirely. This extraction simplifies the door structure while maintaining water dispensing functionality inside the refrigerator space.

Inventive Principle:
Principle #2Taking out (Extraction)

2Device complexity

If a dispenser is provided inside the refrigerator compartment, then door structure is simplified, but space utilization may be reduced due to potential interference with receiving members

Engineering Contradiction:
Improvedoor structure complexityVSAvoidstorage space utilization
Core Design Contradiction:
Device complexityVSVolume of moving object

Solution Approach 1:

The dispenser is positioned in a specific local region of the refrigerator compartment - between the upper and lower receiving members. This localized placement utilizes the vertical space between shelves/drawers that would otherwise be empty, ensuring that the dispenser occupies a niche space without interfering with the horizontal storage capacity of the receiving members.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The dispenser utilizes the vertical dimension of the refrigerator compartment by positioning it between upper and lower receiving members. This vertical placement allows the dispenser to occupy space in the height direction rather than competing for horizontal storage space, effectively using three-dimensional space optimization.

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

3Ease of operation

If the dispenser protrudes forward for easy access, then user convenience is improved, but the available storage space is reduced

Engineering Contradiction:
Improvedispenser accessibilityVSAvoidstorage space
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The dispenser is nested within the space between the upper and lower receiving members, with its front surface substantially flush with the front surfaces of the receiving members. This nesting approach allows the dispenser to be accessible from the front while not protruding beyond the plane of the receiving members, thereby maintaining maximum storage space.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A refrigerator is provided. The refrigerator includes a main body defining a refrigerator compartment and a freezer compartment, a door selectively closing the refrigerator compartment and the freezer compartment, respectively, a plurality of receiving members spaced apart vertically from each other in the refrigerator compartment, and a dispenser between upper and lower spaces of the receiving members, the dispenser supplying drinking water.
