Modular and expandable storage rack for quick assembly and disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage racks occupy a large space and are not conducive to disassembly and storage, as they are structurally characterized by integrated layer plates connected through connecting pieces and long support rods.
Innovation Solution
A storage rack design featuring first and second connecting pieces, support rods, and storage partitions, where the connecting pieces and support rods form a rectangular array, allowing for easy assembly and disassembly by improving the tightness of connections with bumps and reinforcing plates, and enabling the storage partitions to be conveniently disassembled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If integrated layer plates are connected through connecting pieces and long support rods, then the storage rack structure is stable and strong, but the occupied space is large and disassembly is difficult
Solution Approach 1:
The storage rack is divided into modular components: connecting pieces with insert structures, support rods with corresponding insert holes, and layer plates that can be independently assembled and disassembled. This segmentation allows the structure to maintain strength through proper connection mechanisms while enabling easy disassembly by simply removing the layer plates and support rods.
2Stability of the object's composition
If integrated layer plates are connected through connecting pieces and long support rods, then the storage rack maintains structural integrity, but the occupied space during storage is large
Solution Approach 1:
The rack is segmented into discrete components that can be stored separately in a compact manner. The connecting pieces remain fixed while support rods and layer plates can be removed and stored in minimal space, dramatically reducing the volume required for storage when the rack is not in use.
Solution Approach 2:
The support rods are designed to insert into the connecting pieces, creating a nested configuration where components fit within each other. This nesting approach allows the disassembled rack components to be stored in a compact, space-efficient manner while maintaining structural integrity when assembled.
3Ease of operation
If the storage rack is designed to be detachable for transportation and storage, then the ease of disassembly is improved, but the structural strength may be compromised
Solution Approach 1:
The connection system is segmented into insert structures within connecting pieces and corresponding insert holes in support rods. This segmentation enables simple attachment and detachment while maintaining strong connections during use through the interference fit and geometric interlocking of the insert mechanisms.
Solution Approach 2:
The insert structures act as intermediary elements that facilitate strong connections between connecting pieces and support rods. These intermediaries provide both the strength needed for structural integrity and the simplicity required for easy assembly and disassembly operations.

AI summary
A modular and expandable storage rack for quick assembly and disassembly includes a plurality of first connecting pieces, a plurality of second connecting pieces, a plurality of third connecting pieces, a plurality of fourth connecting pieces, a plurality of support rods, and a plurality of storage partitions, which are distributed in a rectangular array respectively. Each storage partition includes four connecting rods. Each first connecting piece, each second connecting piece, each third connecting piece, and each fourth connecting piece include a longitudinally-extending hollow tube and different quantity of side hollow tubes respectively to receive at least one corresponding support rod and at least one corresponding connecting rod. One opposing end of the first longitudinally-extending hollow tube is fixedly provided with a first bump for attaching to an outer side of one corresponding support rod.
