Solution Overview

Problem

Traditional refrigerators with transparent door baskets suffer from exposed mounting parts, compromising their appearance and stability, especially when storage capacity increases or under high loads.

Innovation Solution

A refrigerator design featuring a transparent door basket with a frame part that covers the mounting projection, using a combination of opaque materials and elastic components to ensure stable mounting and prevent separation during door rotation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If the door basket is made transparent to allow users to check foods stored therein, then the appearance is improved and visibility is enhanced, but the mounting part becomes exposed through the transparent material, compromising the appearance

Engineering Contradiction:
ImproveappearanceVSAvoidexposed mounting part
Core Design Contradiction:
ShapeVSObject-generated harmful factors

Solution Approach 1:

A frame part made of opaque material is introduced as an intermediary element between the transparent door basket and the mounting projection. This frame part effectively blocks the view of the mounting projection through the transparent material, resolving the appearance issue while maintaining the transparency benefit for food visibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If the capacity of the door basket is increased to provide more storage space, then the storage capacity is improved, but the mounting stability is lowered, causing the door basket to be arbitrarily separated when the door is opened

Engineering Contradiction:
Improvestorage capacityVSAvoidmounting stability
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The mounting structure is segmented into multiple mounting parts distributed across the door basket. This segmentation allows the mounting force to be distributed across multiple attachment points, maintaining stability even as the overall capacity and size of the door basket increases.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The door basket employs a composite structure combining transparent material for the main body with opaque frame material for structural reinforcement and mounting. This composite approach provides both the desired transparency for visibility and the structural integrity needed for stable mounting of larger capacity baskets.

Inventive Principle:
Principle #40Composite materials

3Shape

If the door basket is made transparent to improve appearance, then aesthetic value is enhanced, but the mounting part is exposed, requiring additional components to shield it

Engineering Contradiction:
Improveaesthetic valueVSAvoidmounting structure
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The frame part serves multiple functions simultaneously: it provides structural support for mounting, shields the mounting projection from view, and reinforces the overall door basket structure. By merging these functions into a single component, the design achieves aesthetic goals without significantly increasing complexity.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A refrigerator includes: a cabinet having a storage space formed therein; a door mounted to the cabinet to open/close the storage space; a mounting projection formed at a rear surface of the door; and a door basket attachably/detachably mounted at the rear surface of the door by the mounting projection, wherein the door basket includes: a storage part formed of a transparent material to allow the inside thereof to be seen, the storage part forming a space in which foods are stored; and a frame part formed at a bottom end of the storage part, the frame part being coupled to the mounting projection to support the door basket and simultaneously shield the mounting projection at the outside.
