Transport Rack Profile Elements from Cardboard Tube
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport frames made of corrugated cardboard or profile elements have unsatisfactory carrying capacity relative to their weight and require a variety of different profiles, leading to complex production processes and non-standardized dimensions.
Innovation Solution
A transport frame formed from at least two units, each comprising a carrying device and a foot device, where all profile elements are made from a single cardboard tube, cut and folded to create tubular profiles with increased stability and axial section modulus, allowing for standardized production and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple different profile elements are used to form transport frames, then the structural stability and carrying capacity are improved, but the device complexity and production complexity increase
Solution Approach 1:
The patent applies universality by using a single standardized cardboard tube that can be transformed into multiple different profile elements (corner profiles, edge profiles, support profiles) through cutting and folding operations. This single tube design serves multiple functions that previously required different specialized components, thereby reducing production complexity while maintaining structural stability and carrying capacity.
Solution Approach 2:
The patent applies segmentation by dividing the single cardboard tube into multiple sections through cutting, where each section is then folded into different profile types. This segmentation allows one standardized component to be transformed into multiple functional elements, reducing the need to manufacture and manage multiple different profile types while maintaining the structural integrity required for carrying capacity.
2Weight of moving object
If corrugated cardboard is used for transport frames, then the dead weight is reduced and ecological benefits are improved, but the carrying capacity relative to weight is insufficient
Solution Approach 1:
The patent applies composite materials by constructing the transport frame from multiple profile elements made from standardized cardboard tubes that are connected through joints and fasteners. This creates a composite structure where the combination of multiple standardized profile elements provides enhanced strength and carrying capacity relative to the total weight, overcoming the limitation of simple corrugated cardboard while maintaining low dead weight and ecological benefits.
Solution Approach 2:
The patent applies dimensionality change by transforming the flat or simple tubular cardboard structure into three-dimensional profile elements with specific geometric configurations (corner profiles, edge profiles, support profiles). This dimensional transformation increases the structural efficiency and carrying capacity relative to the material weight by optimizing the distribution of material in three-dimensional space.
3Ease of manufacture
If standardized cardboard tubes are used for all profile elements, then the production is simplified and inventory is reduced, but the adaptability to special shapes and dimensions is limited
Solution Approach 1:
The patent applies dynamics by designing the standardized cardboard tube system to be transformable through cutting and folding operations. The same standardized tube can be dynamically reconfigured into different profile types and dimensions by varying the cutting patterns and folding angles, allowing adaptation to special shapes and dimensions while maintaining standardized production processes and inventory management.
