Solution Overview

Problem

Traditional scaffolding setup methods require protection systems for worker safety, but these methods are complex and risky, especially when setting up the parapet of an upper floor from a lower floor, as they often lack the necessary protection mechanisms.

Innovation Solution

A modular parapet component with a trapezium profile, comprising vertical and horizontal elements with self-locking hooks and antislippage mechanisms, allowing for safer and faster assembly by enabling bottom-to-top setup without the need for additional protection systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional protection catching systems are used for scaffolding setup, then worker safety is improved, but device complexity and setup time increase

Engineering Contradiction:
Improveworker safetyVSAvoidprotection system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the parapet structure with the protection function by integrating horizontal elements that serve both as structural components and as safety barriers. The parapet itself becomes the protection system, eliminating the need for separate catching systems while maintaining worker safety during setup operations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The parapet is pre-assembled on lower floors before workers need to access upper levels. This preliminary construction of protective elements ensures that safety barriers are already in place before workers begin assembling higher sections, eliminating the need for additional protection systems during the setup process.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If traditional protection systems are implemented, then worker safety is improved, but setup speed and simplicity deteriorate

Engineering Contradiction:
Improveworker safetyVSAvoidsetup speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

By merging the parapet structure with the protection function, the system eliminates separate protection components that would slow down assembly. Workers can simultaneously build the structural framework and the safety barriers using the same modular elements, significantly improving setup speed while maintaining safety.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The parapet elements serve multiple functions: they provide structural support, define the working platform boundary, and simultaneously act as protection barriers. This multi-functionality eliminates the need for dedicated protection systems, allowing workers to assemble both structure and safety features at the same rate.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If modular parapet components are used, then assembly speed is improved, but weight of individual parts increases

Engineering Contradiction:
Improveassembly speedVSAvoidparapet component weight
Core Design Contradiction:
ProductivityVSWeight of moving object

Solution Approach 1:

The parapet is divided into modular components including vertical elements, horizontal elements, and connection pieces that can be independently manufactured and assembled. This segmentation allows each component to be optimized for weight while maintaining the overall structural integrity and protection function of the complete parapet system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different sections of the parapet use varying material thicknesses and densities based on local structural requirements. Critical load-bearing areas use heavier, stronger materials while non-critical sections use lighter materials, optimizing the overall weight distribution and reducing the weight of individual components that need to be handled during assembly.

Inventive Principle:
Principle #3Local quality

AI summary

Parapet (1) for modular scaffolding of the kind made up of a plurality of oblong elements (21, 22, 31, 32, 4), comprising: - a pair of lateral upright elements (21, 22), disposed, when the parapet (1) is assembled over the scaffolding, substantially perpendicular to the trampling floor; - a pair of stringer elements (31, 32) interposed between said lateral upright elements (21, 22) and disposed, when the parapet (1) is assembled over the scaffolding, substantially parallel to the trampling floor; and - a brace element (4), disposed, when the parapet (1) is assembled over the scaffolding, substantially oblique with respect to the trampling floor, the overall arrangement being such that said elements define a trapeze structure and an adjacent triangular structure (Fig. 1A).
