Solution Overview
Problem
Existing display racks, particularly those made of cardboard, lack sufficient strength to support products with considerable weight while allowing high-quality printing on external surfaces, and often require extensive use of plant-based materials.
Innovation Solution
A display rack with a metal skeletal structure covered by a cardboard outer cover, featuring mounting sockets and flaps that wrap around crosspieces, allowing for interchangeable covers and shelves with metal brackets for enhanced stability and printability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cardboard material is used for the display rack, then printing quality on external surfaces is improved, but structural strength to support heavy products deteriorates
Solution Approach 1:
The display rack combines cardboard outer covers with a metal skeletal structure. The cardboard provides printable surfaces while the metal frame provides structural strength, resolving the contradiction between printability and load-bearing capacity.
Solution Approach 2:
The rack is divided into separate components: a metal skeletal structure and interchangeable cardboard outer covers. This segmentation allows each component to fulfill its specific function - metal for strength, cardboard for printing - while working together as a unified system.
2Strength
If metal skeletal structure is used, then structural strength is improved, but ability to support high-quality printing on external surfaces deteriorates
Solution Approach 1:
The solution uses composite construction where the metal skeletal structure provides the load-bearing framework while separate cardboard outer covers provide the printable surfaces, allowing both metal strength and cardboard printability to coexist.
Solution Approach 2:
The cardboard outer cover acts as an intermediary between the metal skeletal structure and the printing function. It transfers the aesthetic and informational functions to the metal frame system, allowing the metal structure to focus on structural support.
3Shape
If extensive plant-based materials are used, then aesthetic appeal is improved, but structural integrity for heavy products deteriorates
Solution Approach 1:
The rack uses a composite of metal and cardboard materials, where the metal provides structural integrity for heavy products while the cardboard covers maintain aesthetic appeal through printable surfaces and natural material appearance.
Solution Approach 2:
Different materials are applied to different parts of the structure: metal is used where structural strength is needed (the skeletal framework), while cardboard is used where aesthetic and informational functions are needed (the outer covers).
