Solution Overview

Problem

Refrigerators face challenges in maintaining freshness of stored foods due to gases like ethylene generated from preserved items, which deteriorate food quality, and existing deodorizing devices are either inefficient or too large for integration within refrigerators.

Innovation Solution

A compact deodorizing device with a suction fan, filters, and UV light emitting modules that efficiently deodorize a large volume of air by using filters and UV light to remove harmful substances, while being designed to fit within the refrigerator without obstructing airflow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a deodorizing device is designed to deodorize a large amount of air per hour, then deodorizing efficiency is improved, but the device size increases making it difficult to integrate within refrigerators

Engineering Contradiction:
Improvedeodorizing efficiencyVSAvoiddevice size
Core Design Contradiction:
ProductivityVSVolume of moving object

Solution Approach 1:

The patent repositions the suction fan from the traditional horizontal airflow configuration to a vertical airflow configuration. The fan draws air from the suction port located at the bottom and discharges it upward through the discharge port, utilizing the vertical dimension to achieve compact integration while maintaining effective air circulation and deodorizing performance within the refrigerator space

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

Solution Approach 2:

The suction fan is pre-positioned adjacent to the suction port before air intake, creating immediate negative pressure that actively draws air through the deodorizing filters. This preliminary positioning ensures efficient air capture and directs it through the UV-C lighting and filtration system, maximizing deodorizing efficiency in a compact configuration

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If the deodorizing device is made compact to fit within refrigerators, then ease of integration is improved, but deodorizing efficiency decreases

Engineering Contradiction:
Improveintegration capabilityVSAvoiddeodorizing efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent combines multiple deodorizing functions into a single integrated unit: the suction fan, UV-C light emitting module, and deodorizing filters are merged into one compact assembly. This unified structure maintains effective deodorizing performance while achieving the compact size needed for refrigerator integration

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

By transitioning to vertical airflow configuration, the device exploits the vertical space within the refrigerator to achieve compact horizontal footprint while maintaining sufficient air processing capacity for effective deodorizing

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

3Reliability

If traditional deodorizing devices are used, then deodorizing function is provided, but they are too large to be attached to the interior of the refrigerator

Engineering Contradiction:
Improvedeodorizing functionVSAvoiddevice size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The suction fan is reconfigured to operate in a vertical airflow orientation, drawing air from the bottom suction port and discharging it upward. This dimensional change allows the device to maintain its deodorizing function while reducing its horizontal footprint to fit within refrigerator interior space constraints

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

Solution Approach 2:

The suction fan is positioned immediately adjacent to the suction port before air intake, creating immediate negative pressure that actively draws air through the compact deodorizing system. This preliminary positioning ensures efficient air capture and directs it through the UV-C lighting and filtration system within the compact device structure

Inventive Principle:
