Solution Overview

Problem

Typical refrigerators with transparent door baskets suffer from exposed mounting parts, reduced mounting stability due to increased storage capacity, and risk of arbitrary separation when the door is opened, compromising both appearance and user convenience.

Innovation Solution

A refrigerator design featuring a door basket with a transparent storage part and a firm frame part, where the mounting projection is covered by the frame part, providing stable support and secure attachment through a horizontal extension and elastic fixation system, ensuring the door basket remains securely attached even under increased load or rotation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of stationary object

If the storage capacity of the door basket is increased, then the mounting stability is lowered, but the door basket may separate arbitrarily

Engineering Contradiction:
Improvestorage capacity of door basketVSAvoidmounting stability of door basket
Core Design Contradiction:
Volume of stationary objectVSStability of the object's composition

Solution Approach 1:

The mounting structure is segmented into multiple independent mounting parts distributed across the door basket. Instead of relying on a single mounting point, the door basket is provided with multiple mounting parts that engage with corresponding mounting projections on the door. This segmentation distributes the mechanical load across multiple attachment points, preventing arbitrary separation even when the storage capacity and weight of the door basket are increased.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If the door basket capacity is increased, then more foods can be stored, but the mounting stability decreases under increased load

Engineering Contradiction:
Improveamount of foods storedVSAvoidmounting strength under load
Core Design Contradiction:
Quantity of substanceVSStrength

Solution Approach 1:

The mounting structure is divided into multiple mounting parts that are distributed across the door basket. Each mounting part engages with a corresponding mounting projection on the door, creating multiple attachment points. This segmentation allows the mounting system to distribute the weight of stored foods across multiple engagement points, maintaining mounting strength even when the storage capacity is increased to hold more and heavier foods.

Inventive Principle:
Principle #1Segmentation

AI summary

A refrigerator (1) includes: a cabinet (10) having a storage space formed therein; a door (30, 50) mounted to the cabinet (10) to open/close the storage space; a mounting projection (200) formed at a rear surface of the door (30, 50); and a door basket (100) attachably/detachably mounted at the rear surface of the door (30, 50) by the mounting projection(200), wherein the door basket (100) 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 (200) to support the door basket (100) and simultaneously shield the mounting projection (200) at the outside.
