Solution Overview

Problem

Existing refrigerator shelf systems are complex to install and remove, requiring separate storage and often involving slidable mechanisms that are costly and difficult to manage.

Innovation Solution

A pivotable shelf system where the shelf is supported by a holder guided along the side edge of an intermediate floor, allowing the shelf to be easily extended in length without protruding above the floor, with a guide mechanism that includes a support element with a guide groove and projection for space-saving folding and locking, and U-shaped support rails for protection and easy assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a slidable mechanism is used to extend the shelf, then the storage space can be increased, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improvestorage spaceVSAvoidmechanism complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The shelf is designed to be pivotable between a folded position (parallel to intermediate floor) and an unfolded position (below intermediate floor), transforming a static structure into a dynamic one that adapts storage capacity based on need without complex slidable mechanisms

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The shelf system is divided into separate components: the intermediate floor, the shelf, and the holder with pivot mechanism, allowing independent assembly and simplifying the overall structure while maintaining functionality

Inventive Principle:
Principle #1Segmentation

2Volume of moving object

If the shelf is made larger to increase storage area, then more goods can be stored, but the shelf protrudes above the intermediate floor when folded

Engineering Contradiction:
Improvestorage areaVSAvoidshelf length
Core Design Contradiction:
Volume of moving objectVSLength of stationary object

Solution Approach 1:

The shelf extension is achieved by utilizing the vertical dimension through pivoting motion, allowing the shelf to extend below the intermediate floor rather than protruding above it, thus increasing storage area without increasing the horizontal footprint when folded

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

3Ease of operation

If the holder is not guided along the side edge, then the structure is simpler, but the shelf cannot be pushed backwards in a space-saving manner

Engineering Contradiction:
Improvespace-saving positioningVSAvoidguide structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The guide groove acts as an intermediary element between the holder and the intermediate floor, providing guided motion that enables space-saving positioning while keeping the overall structure simple and easy to manufacture

Inventive Principle:
Principle #24Intermediary (Mediator)
