Lattice Shelf Profile Nesting for Load Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lattice shelves for storage racks lack sufficient stability and load-bearing capacity, particularly when storing heavy loads, due to inadequate connection points and contact areas between crossbeams and support profiles.
Innovation Solution
The lattice shelf design incorporates angled wire ends of the wire mesh mat that dip into outer profile supports, with support profiles and outer profile supports featuring C-shaped cross-sections and recesses for secure insertion of intermediate profile carriers, and vertical tabs that provide additional framing and fixation, allowing for a self-supporting and mutually supporting connection of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If complex plug-in connections with pronounced contact areas are used to ensure load-bearing capacity, then the load-bearing capacity is improved, but the device complexity increases
Solution Approach 1:
The patent implements nesting by inserting the C-shaped cross-beams into the C-shaped support profiles, creating a nested structure where one profile is placed within another. This nested configuration provides inherent stability and load-bearing capacity through the interlocking geometry, eliminating the need for complex additional connection mechanisms while maintaining structural strength.
2Stability of the object's composition
If multiple connection points with notches and tabs are implemented, then the stability is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent changes the geometric parameters of the profiles by using C-shaped cross-sections with specifically designed openings, notches, and tabs. These parameter modifications allow the profiles to interlock and provide structural stability through their shape alone, eliminating the need for complex manufacturing processes while ensuring stable assembly through the inherent geometry of the nested components.

AI summary
The rack (1) has front and rear outer profiles (7a) that are provided in the installed position on the shelf transverse bearing profiles (6), and is orthogonal to the bearing profiles that extend in the longitudinal direction of rack. A profiled support and a wire mesh mat (9) extend between the outer profiles, and are provided in the outer profile member dipping wire ends (14). The bearing profile and the outer profile have C-shaped cross-section and the bearing profile is formed with recesses into which the outer profile and the support are inserted.
