Modular Rack Assembly with Independent Shelf Adjustment Levels

Solution Overview

Problem

Conventional modular rack assemblies require time-consuming and labor-intensive processes to add or remove intermediate shelf units, as they necessitate the removal of articles and subsequent components above the target height, disrupting the storage arrangement.

Innovation Solution

The modular rack assembly features a support rod module with upright legs having specific hole configurations and a shelf module with position-limiting members and sleeves, allowing for the quick and lateral assembly or disassembly of shelf units without disturbing upper components, utilizing second shelf units with insertion holes and supporting members for height adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If shelf units are sequentially connected to support rods from bottom to top with limiting members, then the structure provides stable support and easy assembly, but removing or adding intermediate shelf units requires removing all components above the target height, which is time-consuming and labor-consuming

Engineering Contradiction:

Improveease of shelf unit adjustmentVSAvoidtime for shelf unit removal and addition

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The support rod is divided into multiple independent connection levels, each with its own limiting member and engagement structure. This segmentation allows each shelf unit to be independently attached or detached from the support rod without affecting other levels, enabling intermediate shelf units to be removed or added without disturbing components above or below the target position.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If shelf units are sequentially connected to support rods from bottom to top with limiting members, then the structure provides stable support and easy assembly, but the process of adding or removing intermediate shelf units requires displacing articles from upper shelves, which is labor-intensive

Engineering Contradiction:

Improveease of shelf unit adjustmentVSAvoiddisplacement of articles during shelf adjustment

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The support rod is divided into multiple independent connection levels, each with its own limiting member and engagement structure. This segmentation allows each shelf unit to be independently attached or detached from the support rod without affecting other levels, enabling intermediate shelf units to be removed or added without disturbing components above or below the target position.

AI summary

A modular rack assembly includes upright support legs, two first shelf units, and a second shelf unit. Each upright support leg has two spaced-apart first hole units, and a plurality of spaced-apart second holes disposed between the first hole units. The first shelf units are connected to the upright support legs through the first hole units. The second shelf unit is engaged to the second holes of the upright support legs which are at the same height, and includes a second shelf plate formed with insertion holes, and supporting members that are engaged to the second holes at the same height and that are inserted into the insertion holes to support the second shelf plate.
