Solution Overview

Problem

Modular scaffolding systems face limitations in height due to overstressing at the connection area of horizontal beams to vertical supports, requiring enhanced load-bearing capacity and ease of assembly.

Innovation Solution

A corner strut with different connecting elements at each end, allowing for simple connection to horizontal bars without tools and secure attachment to vertical supports via movable connecting means and locking mechanisms, such as pipe clamps or pawls, which can be easily assembled and disassembled.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of stationary object

If the scaffolding height is increased, then the scaffolding can reach higher buildings, but the loads at the connection points increase excessively

Engineering Contradiction:

Improvescaffolding heightVSAvoidload at connection point

Core Design Contradiction:

Length of stationary objectVSStress or pressure

Solution Approach 1:

The connection system is divided into separate functional components: a first connecting element for the horizontal beam and a second connecting element for the vertical post, allowing independent optimization of each connection's load-bearing capacity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different connecting elements are used at different locations based on their specific load requirements - the first connecting element is simplified for horizontal beam connection while the second connecting element with movable components and locking means is designed for high-load vertical post connection

Inventive Principle:

Principle #3Local quality

2Strength

If additional connecting elements are added to reinforce the connection, then the load-bearing capacity increases, but the assembly complexity increases

Engineering Contradiction:

Improveload-bearing capacityVSAvoidassembly complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The second connecting element incorporates movable components that can be positioned and locked into place, allowing the connection to be made quickly and easily while maintaining high load-bearing capacity through the locking mechanism

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The locking means enable the connecting elements to secure themselves to the vertical post without requiring additional fastening tools or complex assembly procedures, reducing assembly complexity while maintaining strength

Inventive Principle:

Principle #25Self-service
