Combined type shelf
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional combined type shelves require specific tools for assembly and disassembly, making the process difficult and time-consuming, and they lack flexibility for horizontal extension, reducing user convenience.
Innovation Solution
The design incorporates double-rod frames with connecting assemblies and storage-layer connector structures that allow for tool-free assembly and disassembly, providing a simple, solid, and flexible shelving system without the need for cross-shaped lead lines, enabling horizontal extension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cross-shaped lead line structures and welding are used to mount storage layers to double-rod frames, then the shelf structure becomes fixed and stable, but assembling and disassembling requires specific tools and becomes difficult and time-consuming
Solution Approach 1:
The shelf is divided into modular components: double-rod frames, storage layers, and connecting assemblies that can be independently assembled and disassembled. The connecting assembly includes a main body, back portion, and engaging structures that separate the storage layer from the frame, enabling tool-free assembly while maintaining stability during use.
Solution Approach 2:
The connecting assembly transitions from a static welded connection to a dynamic, reversible connection system. The engaging structures allow the storage layer to be easily attached and detached from the double-rod frame without tools, providing both stability when assembled and ease of reconfiguration when disassembled.
2Reliability
If cross-shaped lead line structures are mounted to double-rod frames at the rear portion, then storage layers can be mounted fixedly, but the shelf structure inhibits horizontal extension and reduces use convenience
Solution Approach 1:
The connecting assembly serves multiple functions: it provides fixed mounting of storage layers to double-rod frames, enables horizontal extension by allowing additional frames to be connected, and facilitates easy assembly and disassembly. The standardized engaging structures work across different shelf configurations, making the system versatile and adaptable.
Solution Approach 2:
The connecting assembly features a nested structure where the back portion fits within the space between the double-rod frames, and the engaging structures are integrated within the main body. This nested design allows horizontal extension without requiring external support structures, as each connecting assembly is self-contained and can be added between existing frames.
3Strength
If conventional shelf structures use welded metal wires to frames, then the structure becomes solid, but both assembling and disassembling become difficult and time-consuming requiring specific tools
Solution Approach 1:
The welding process is replaced with a mechanical engagement system. The connecting assembly uses engaging structures that mechanically connect the storage layer to the double-rod frame through insertion and engagement actions, eliminating the need for welding tools and processes while maintaining structural solidity during use.
Solution Approach 2:
The connecting assembly is designed to be self-assembling through simple insertion and engagement actions that do not require external tools. The engaging structures are configured to automatically secure the storage layer to the frame when properly positioned, allowing users to assemble and disassemble the shelf quickly without specialized equipment or extensive time investment.

AI summary
A combined type shelf includes double-rod frames, connecting assemblies, double-rod frames and storage-layer connector structures. The double-rod frame includes vertical post assemblies and horizontal rods, and the vertical post assembly includes a first straight upright rod and a second straight upright rod parallel to each other to provide a gap for receiving therebetween ends of the plurality of horizontal rods. The connecting assembly includes a main body, a back portion, a horizontal-rod engaging groove, a vertical-rod engaging groove and a first connecting-piece engaging cavity. The storage layer is disposed between the double-rod frames. The storage-layer connector structure, disposed to the storage layer, includes an inserting piece to be plugged into the first connecting-piece engaging cavity to connect each of the storage-layer connector structures to the connecting assembly to assemble the storage layer to the double-rod frame.
