Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scaffolding systems are heavy and expensive due to their design, which makes them difficult to manufacture and transport, and poses a challenge in achieving the necessary structural strength and weight optimization.
Innovation Solution
A vertical frame for scaffolding is designed using hollow profiles with a diagonal strut that connects the horizontal and vertical struts, providing increased structural strength and allowing for lighter materials to be used, while also optimizing manufacturing processes through welded connections and the use of different metals for weight and strength optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional scaffolding designs are used, then structural strength is achieved, but weight increases and manufacturing complexity increases
Solution Approach 1:
The patent applies parameter changes by using hollow profiles with optimized wall thicknesses and specific cross-sectional dimensions. The diagonal strut has a rectangular, oval or pentagonal cross section with dimensions specifically designed to achieve the necessary structural strength while minimizing weight. The wall thickness and external dimensions are precisely controlled parameters that balance strength requirements with weight reduction goals.
Solution Approach 2:
The patent employs composite construction by combining multiple hollow profile elements (vertical struts, horizontal struts, diagonal struts) with different cross-sectional characteristics to create a vertically integrated frame structure. The diagonal strut with its distinct rectangular, oval or pentagonal cross section complements the round tube vertical and horizontal struts, creating a composite structural system that achieves superior strength-to-weight ratio compared to traditional homogeneous designs.
2Stability of the object's composition
If traditional scaffolding designs are used, then structural stability is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent applies segmentation by dividing the vertical frame into distinct modular components: vertical struts, horizontal struts, and diagonal struts, each made from hollow profiles with specific cross-sectional characteristics. This segmentation allows each component to be manufactured independently using standardized hollow profile production methods, simplifying the overall manufacturing process while maintaining structural stability through the integrated assembly of these segmented elements.
Solution Approach 2:
The patent uses parameter changes by specifying precise wall thicknesses and cross-sectional dimensions for each strut type. The hollow profiles are manufactured with controlled parameters (external dimensions, wall thickness tolerances) that ensure structural stability when assembled. The diagonal strut's rectangular, oval or pentagonal cross section with specific dimensions provides enhanced stability while remaining compatible with standard hollow profile manufacturing processes.
3Weight of moving object
If hollow profiles are used, then weight is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent addresses manufacturing precision requirements by establishing specific parameter ranges for the hollow profiles. The wall thicknesses and external dimensions are defined with controlled tolerances that balance weight reduction with manufacturability. The diagonal strut's cross-sectional parameters (rectangular, oval or pentagonal with specified dimensions) are designed to achieve the necessary precision levels using conventional hollow profile manufacturing techniques.
Solution Approach 2:
The patent applies segmentation by using standardized hollow profile segments that can be manufactured with consistent precision using established production methods. Each strut type (vertical, horizontal, diagonal) is a segmented component with defined dimensional parameters, allowing for controlled precision manufacturing. This segmentation approach enables the use of off-the-shelf hollow profiles with tight manufacturing tolerances, reducing the need for custom high-precision fabrication.

AI summary
The invention relates to a vertical frame (10) for a scaffold. The vertical frame (10) comprises at least two vertical struts (11) and at least one horizontal strut (12). At least one diagonal strut (13) is provided between the horizontal strut (12) and the vertical strut (11). The diagonal strut (13) is made of a hollow profile having a cross-section with different axial dimensions. A second outer dimension of the cross-section of the diagonal strut (13) is smaller than a first outer dimension of the diagonal strut (13). The diagonal strut (13) is fixed to the horizontal strut (12) and to the vertical strut (11) such that the longer dimension is arranged substantially perpendicular to a plane spanned between the horizontal strut (12) and the vertical strut (11).
