Corrugated Cantilevered Display Rack for Shelf Visibility and Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display racks do not utilize corrugated paper material with a support frame having only two angled walls and openings for receiving three corners of reinforced shelves, resulting in shelves being cantilevered with only one edge exposed for visibility and access.
Innovation Solution
A display rack made of fully recyclable corrugated paper with a support frame having two angled walls and tubular reinforcing structures, where shelves are cantilevered with two edges exposed by engaging their corners into openings in the frame, providing enhanced visibility and access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If display racks are made with a back wall and two side walls (cabinet-like structure), then structural stability is improved, but only one edge of the shelves is exposed reducing visibility and access
Solution Approach 1:
The invention removes the back wall from the traditional cabinet-like display rack structure, extracting only the necessary two side walls to maintain stability while allowing shelves to cantilever forward. This extraction enables two edges of each shelf to be exposed, significantly improving visibility and customer access to displayed articles.
2Ease of operation
If shelves are cantilevered from support walls, then visibility and access are improved, but structural strength may be compromised
Solution Approach 1:
The invention uses corrugated fiberboard, a composite material with fluted inner layer sandwiched between flat outer layers, to construct both the support walls and shelves. This composite structure provides exceptional strength-to-weight ratio, enabling the shelves to cantilever forward with two edges exposed while maintaining the structural strength to support heavy articles.
Solution Approach 2:
The support walls are formed with curved surfaces that provide structural reinforcement while maintaining an attractive display appearance. The curvature distributes stress more effectively, enhancing the strength of the cantilevered shelf structure.
3Strength
If traditional display racks are made of wood or metal, then structural strength is improved, but recyclability and environmental friendliness are reduced
Solution Approach 1:
The invention uses corrugated fiberboard, a recyclable material, for the entire display rack construction. After use, the racks can be easily disassembled and the fiberboard material recovered for recycling, eliminating the need for metal or wood disposal and supporting environmental sustainability initiatives.

AI summary
A display rack for displaying articles has a support frame with two walls extending at an angle from a narrow strip at the rear corner of the frame. A tubular reinforcing structure extends along the forward free edge of each wall, and aligned openings are in the strip and the reinforcing structures. A plurality of shelves having front and rear corners and opposite side corners are supported on the frame between the walls, with the rear corners engaged in respective openings in the strip and the side corners engaged in respective openings in the reinforcing structures. A forward portion of the shelves projects forwardly of the frame for greater visibility of and access to articles supported on the shelves. A reinforcing brace extends diagonally in each shelf from the rear corner to the front corner, whereby the shelves are essentially cantilevered from the frame.
