Assembled shelf
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shelf structures are inconvenient to assemble due to the need for numerous snap-on locators and have weak stability, leading to reduced assembly efficiency and load-bearing capacity.
Innovation Solution
A shelf assembly system featuring a positioning hanger and a locking fastener that work together to securely attach main beams to uprights, allowing for quick and convenient assembly while enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional snap-on locators composed of two pieces A and B are used, then the shelf can be assembled with standard components, but the assembly process becomes troublesome and assembly efficiency is reduced
Solution Approach 1:
The patent combines two separate snap-on locators (pieces A and B) into a single integrated locator component. This merging eliminates the need to find and assemble multiple matching pieces during installation, directly resolving the technical contradiction by maintaining standard component availability while significantly improving assembly efficiency.
2Device complexity
If traditional snap-on locators are used, then the shelf structure can be simple, but the fixing effect between locators and connecting fixtures is insufficient, resulting in weak load-bearing capacity and stability
Solution Approach 1:
The patent segments the connection function into two distinct parts: the snap-on locator that provides positioning and the integrated fixing member that provides secure attachment. This segmentation allows each component to be optimized for its specific function while working together, resolving the contradiction between structural simplicity and connection reliability.
Solution Approach 2:
The patent introduces an intermediate fixing member that acts as a mediator between the snap-on locator and the connecting fixture. This intermediary component enhances the fixing effect and load-bearing capacity while maintaining the overall simplicity of the connection structure.

AI summary
An assembled shelf including main beams and uprights is disclosed. The main beam is detachably fixed to the upright through a shelf beam connection structure that includes a positioning hanger and a locking fastener. When assembling, a hanger body of the positioning hanger is attached to a surface of the upright, a hanging hook portion is positioned and clamped on a second side edge; then the fastening hook portion is clamped on the second side edge, the hanger body is embedded into the fastener body, and the positioning hanger positioned and clamped on the upright is tightly locked; next the main beam is connected to the locking fastener. The shelf is easy to be assembled, the stability of the assembled shelf is better.
