Modular Storage Frame Assembly With Nested Positioning Tubes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional modular storage frames face difficulties in assembly due to the lack of anti-slip and positioning functions in the coupling tube, making it challenging to engage handles and pressed elements effectively.
Innovation Solution
The modular storage frame design includes coupling heads with top and bottom coupling portions, neck portions with cavities, and joining tubes with positioning elements, which form an enclosed area to securely position storage boards, and supporting elements that allow for height adjustment and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If coupling tubes with radially reduced thickness and smooth peripheral surface are used, then the structure is simplified, but the anti-slip and positioning function is lost
Solution Approach 1:
The coupling tube is divided into multiple functional segments: the outer tube provides structural support, while the inner tube with positioning elements provides engagement functionality. This segmentation allows each part to have optimized characteristics - the outer tube can be simple and smooth, while the inner tube provides the necessary anti-slip and positioning features through its positioning elements.
Solution Approach 2:
The inner tube is nested within the outer tube, with the inner tube's positioning elements extending through the outer tube's wall. This nested configuration allows the positioning elements to protrude from the smooth outer surface, providing engagement functionality without compromising the simplicity and smoothness of the outer tube structure.
2Adaptability or versatility
If supporting elements are added for height adjustment and movement, then the functionality is enhanced, but the assembly complexity increases
Solution Approach 1:
The supporting elements are designed to perform multiple functions: they provide height adjustment capability, enable movement/repositioning, and maintain structural support. By integrating these functions into a single component that couples with both the coupling heads and inner tubes, the design enhances versatility without proportionally increasing complexity.
Solution Approach 2:
The supporting elements feature self-adjusting mechanisms that allow users to easily modify height and position without requiring complex tools or procedures. The coupling design between supporting elements, coupling heads, and inner tubes enables intuitive assembly and adjustment, making the system self-explanatory and easy to configure.

AI summary
A modular storage frame includes: at least two storage floors each having four coupling heads, four coupling tubes, at least four opposing elements and a storage board, wherein the coupling head has two coupling portions, two neck portions and a joining portion; at least four joining tubes having four inner tubes and four outer tubes; and four supporting elements coupling respectively with the bottommost ones of the inner tubes, wherein the outer tube has two positioning elements protruding to an outside thereof. The positioning elements may provide the storage floors to be relatively firmly positioned. The opposing elements protruding from the coupling tubes may have the storage board to be easily placed and the plight that the opposing elements are not easily assembled with the coupling heads may be avoided.
