Solution Overview

Problem

The assembly process for configuring ducts in refrigerators is complex, and the space for storing food is reduced due to the volume occupied by the ducts.

Innovation Solution

A food storage apparatus with ducts that directly diverge from a scroll part with a blowing fan, reducing the total duct length and integrating the duct, damper, and scroll part into one body, simplifying the manufacturing process and reducing assembly difficulties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional duct assembly process is used, then duct configuration is achieved, but assembly complexity increases and manufacturing cost rises

Engineering Contradiction:
Improveduct assembly processVSAvoidassembly complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines the duct, damper, and scroll part into a single integrated duct unit. The duct body serves as both the air passage structure and the housing for the damper mechanism, eliminating the need for separate assembly of these components. This merging approach directly reduces assembly complexity while maintaining the functional integrity of each component.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If traditional duct configuration is used, then air guidance function is achieved, but storage space is reduced due to duct volume

Engineering Contradiction:
Improvecold air guidanceVSAvoidstorage room volume
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The patent positions the scroll part vertically above the duct body, utilizing the vertical dimension rather than horizontal expansion. This dimensional reorganization allows the air guidance function to be achieved while minimizing the horizontal footprint and maximizing the storage room volume. The cold air is guided upward through the scroll part and then distributed, maintaining functionality while optimizing space utilization.

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

3Ease of manufacture

If duct and damper are separate components, then individual component manufacturing is simplified, but overall assembly difficulty increases

Engineering Contradiction:
Improvecomponent manufacturingVSAvoidassembly difficulty
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The damper is integrated within the duct body structure, with the damper blade rotating within the duct's air passage. The damper shaft extends through the duct wall and connects to the scroll part, creating a unified structure where the damper cannot be separated from the duct. This integration eliminates assembly steps while maintaining the ability to manufacture each functional element with standard processes.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If multiple separate duct components are used, then flexibility in configuration is improved, but productivity is reduced due to increased assembly steps

Engineering Contradiction:
Improveduct configuration flexibilityVSAvoidwork productivity
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The integrated duct unit incorporates a rotatable damper blade that can dynamically adjust the air flow distribution to different storage rooms. The damper shaft can rotate to redirect cold air to either the first or second storage room, providing operational flexibility without requiring multiple separate duct configurations. This dynamic adjustment capability maintains adaptability while significantly improving productivity by eliminating assembly variations.

Inventive Principle:
Principle #15Dynamics
